Sheet Pan Garlic Butter Lobster with Golden Scallops

Sheet Pan Garlic Butter Lobster & Golden Scallops – The Ultimate Easy Seafood Dinner

I still remember the first time I made this Sheet Pan Garlic Butter Lobster and Golden Scallops — it was a quiet Tuesday evening in my tiny NYC apartment, and I wanted something that felt like a celebration without spending hours in the kitchen. Growing up in Morocco, my mother would prepare seafood with such reverence — pinching cinnamon and saffron into tagines, basting fish with spiced butter until the whole house smelled like the sea met the spice souk. Now, living in New York and trained in classic French kitchens, I’ve learned that the best dishes are the ones that carry a bit of your story. This garlic butter seafood sheet pan recipe is that dish for me: it’s weeknight-easy but dinner-party-fancy, with a thick, scroll-stopping avocado drip that turns a simple sheet pan into art. The first time I pulled that tray from the oven, with the lobster tail glistening and the scallops golden at the edges, I knew I’d created something I’d make again and again — and now I’m sharing it with you.

Imagine this: a single sheet pan, brushed with a garlic butter baste so fragrant it’ll make your neighbors knock on your door, carrying a split lobster tail that’s been butterflied and set right on the shell, alongside plump sea scallops that turn golden and tender in just twelve minutes. The butter sizzles as it hits the hot seafood, and the paprika and Old Bay seasoning bloom in the heat, creating a crust that’s both delicate and deeply savory. Underneath it all, a bed of crunchy purple cabbage slaw adds a cool, tangy bite, and then — the moment that makes this recipe unforgettable — you flood everything with a thick, pale green avocado sauce that drips over the seafood and pools into the slaw. It’s the kind of visual that stops you mid-scroll, and the kind of flavor that keeps you coming back for more. Every forkful is a contrast: warm and cool, rich and bright, tender and crunchy.

What sets this easy lobster scallop dinner apart from other sheet pan recipes is the technique I brought from my training in Paris — the way we pat seafood perfectly dry before seasoning (a non-negotiable step I learned at Le Cordon Bleu), and the careful balance of garlic butter that’s brushed generously but not drowning. The avocado drip is my own twist, inspired by the creamy sauces I grew up eating alongside grilled fish in Morocco. I’ve tested this recipe a dozen times to get the timing just right — no overcooked scallops, no tough lobster, just pure, buttery perfection. 💡 Stella’s Pro Tip: The key to the most tender scallops is placing them with a little space between each one on the sheet pan, so they brown rather than steam. And if you’re wondering whether this is a beginner-friendly recipe — absolutely yes. A sheet pan does the heavy lifting, and I’ll walk you through every step. Let’s get cooking.

Why This Sheet Pan Garlic Butter Lobster and Scallops Recipe Is the Best

The Flavor Secret: This isn’t just garlic butter — it’s a garlic butter baste enriched with a splash of seafood broth and fresh lemon juice, which keeps the seafood moist while adding depth. The paprika and Old Bay bring a smoky, slightly spicy warmth that complements the natural sweetness of lobster and scallops. I learned in Paris that butter sauces need acidity to balance richness, and that bright finish is what makes this garlic butter seafood sheet pan recipe sing. It’s the same principle my mother used when she’d squeeze lemon over grilled fish in our Moroccan courtyard — simple, but transformative.

Perfected Texture: The challenge with cooking lobster and scallops together is that they have different cook times — but not in this recipe. By splitting the lobster tail and keeping it attached to the shell, and by selecting large sea scallops (about 1 ½ inches wide), both proteins finish at the same moment. The scallops develop a golden crust while staying tender inside, and the lobster becomes opaque and succulent. The technique of patting the seafood bone-dry before seasoning — a classic French mis en place — ensures you get browning, not steaming. ⚠️ Common Mistake to Avoid: Don’t skip drying the seafood! Even a little moisture will cause the scallops to release liquid and stew instead of sear.

Foolproof & Fast: Thirty minutes from fridge to table, including prep. The sheet pan keeps cleanup minimal, and the slaw and avocado drip come together while the seafood bakes. This is the kind of recipe that makes you look like a hero on a Wednesday night. I’ve made it for friends who thought cooking lobster was intimidating, and they were shocked at how simple it was — because really, the oven does the work. All you need is a sharp pair of kitchen shears and a blender for the sauce.

Sheet Pan Garlic Butter Lobster and Scallops Ingredients

One of my favorite things about living in New York City is having access to incredible seafood at markets like Citarella and the Union Square Greenmarket. I hand-pick my lobster tails there — always cold-water, always with the shell intact. The scallops I look for are dry-packed (never soaked in preservative solution, which makes them waterlogged). Below is everything you’ll need, plus my tested substitutions so you can adapt this sheet pan garlic butter lobster and scallops recipe to what’s available in your area.

Ingredients List

• The Sheet Pan Seafood:
• 1 large lobster tail (10 to 12 oz)
• 1 lb large sea scallops
• ½ tsp paprika
• ½ tsp Old Bay seasoning
• ¼ tsp salt
• ¼ tsp black pepper
• The Garlic Butter Baste:
• 5 tbsp unsalted butter, melted
• 4 cloves garlic, finely minced
• 1 tbsp fresh lemon juice
• 1 tbsp seafood or chicken broth
• 1 tbsp fresh parsley, finely chopped
• The Crunchy Slaw:
• 2 cups shredded purple cabbage
• 1 tbsp lime juice
• The Thick Pale Green Avocado Drip:
• 1 ripe avocado
• ¼ cup sour cream or Greek yogurt
• 1 tbsp lime juice

Ingredient Spotlight

Lobster Tail (10–12 oz): The star of the show. Look for cold-water tails (from Maine or Canada) — they have firmer, sweeter meat. If you only find smaller tails (6–8 oz), use two and reduce the bake time by 2–3 minutes. Frozen tails work beautifully; just thaw overnight in the fridge. I often pick up a few extra when they’re on sale at my local Whole Foods and keep them in the freezer for quick dinners.

Large Sea Scallops (1 lb): Dry-packed scallops are essential here — they sear instead of boil. If you can only find wet-packed (soaked in sodium tripolyphosphate), pat them extremely dry and expect slightly less browning. I buy mine from the fish counter at Fairway and ask for “dry-packed diver scallops” — they’re worth the extra dollar per pound. For a budget-friendly swap, you can use large shrimp, but reduce the cook time to 8 minutes.

Avocado (for the drip): Hass avocados give the creamiest, richest sauce. The avocado should yield gently to pressure but not feel mushy. If your avocado isn’t ripe yet, you can substitute with an extra ¼ cup of sour cream and a tablespoon of olive oil, though the color will be less vibrant. The lime juice in the drip isn’t just for flavor — it prevents the avocado from oxidizing and keeps that pale green color gorgeous.

Original Ingredient	Best Substitution	Flavor / Texture Impact
Lobster tail (10–12 oz)	2 small lobster tails (6–8 oz) or 1 lb large shrimp	Shrimp will be quicker to cook (8 min); less sweet than lobster but still delicious
Large sea scallops (1 lb dry)	1 lb large shrimp or 1 lb firm white fish (cod, halibut)	Fish will cook faster (8–10 min) and won’t get the same golden crust
Sour cream (avocado drip)	Full-fat Greek yogurt or coconut cream (for dairy-free)	Greek yogurt is slightly tangier; coconut cream adds tropical sweetness
Purple cabbage slaw	Shredded green cabbage + carrot, or arugula for a peppery bite	Arugula will wilt slightly from the hot seafood; less crunch but more flavor

How to Make Sheet Pan Garlic Butter Lobster and Scallops — Step-by-Step

This baked scallops and lobster recipe comes together faster than you’d think — here’s exactly how to do it, with my chef-tested tips so every component is perfect.

Step 1: Prepare the Seafood

Pat the lobster meat and scallops very dry with paper towels — this is the single most important step for golden browning. In a small bowl, mix the paprika, Old Bay seasoning, salt, and black pepper, then sprinkle the mixture evenly over both sides of the scallops and the exposed lobster meat. Using kitchen shears, carefully cut through the top of the lobster shell from the tail fin to the top, then gently lift the meat above the shell, keeping it attached at the base. This “butterfly” technique ensures even cooking and that beautiful presentation.

💡 Stella’s Pro Tip: Use sharp kitchen shears, not a knife, to split the lobster shell — it’s safer and gives you more control. Cut in a straight line down the center of the softer underside of the tail.

Step 2: Make the Garlic Butter

In a small bowl, whisk together the melted butter, finely minced garlic, fresh lemon juice, seafood or chicken broth, and chopped parsley. The broth might seem like a small addition, but it keeps the butter from separating and adds a savory backbone that plain butter doesn’t have. Set aside about 2 tablespoons of the butter for brushing after baking — this will give the seafood a final glossy finish.

⚠️ Common Mistake to Avoid: Don’t let the butter sit too long after adding the garlic — if the butter cools and solidifies, the garlic won’t distribute evenly. Whisk it again just before brushing.

Step 3: Sheet Pan Bake

Place the prepared lobster tail and scallops onto a parchment-lined baking sheet. Space the scallops about 1 inch apart — crowding them will trap steam and prevent browning. Generously brush the garlic butter mixture over the exposed lobster meat and the top of each scallop. Reserve a little butter for drizzling after baking. Bake in an oven preheated to 425°F (220°C) for 10 to 13 minutes. The lobster is done when it’s opaque and just firm to the touch; the scallops should be golden on the edges and tender in the center. If you’re using an instant-read thermometer, lobster should read 135°F and scallops 120°F.

💡 Stella’s Pro Tip: For extra golden scallops, switch the oven to broil for the final 1–2 minutes. Watch closely — they go from golden to overdone fast!

Step 4: Make the Slaw and Drip

While the seafood bakes, toss the shredded purple cabbage with lime juice in a medium bowl. Let it sit for at least 5 minutes to soften slightly and absorb the citrus. In a blender, combine the ripe avocado, sour cream (or Greek yogurt), and lime juice. Blend on high until completely smooth, scraping down the sides once. The sauce should be thick enough to hold its shape when drizzled — if it’s too thick, add a teaspoon of water; if too thin, add another spoonful of sour cream.

⚠️ Common Mistake to Avoid: Don’t over-blend the avocado sauce — it can become bitter if blended too long. Pulse until smooth, then stop. And taste it: adjust salt and lime as needed.

Step 5: Assemble and Drip

Lay down a generous bed of the crunchy purple cabbage slaw on a serving plate or shallow bowl. Arrange the hot, golden scallops and the lobster tail on top. Drizzle the reserved garlic butter over the seafood for extra shine, then flood everything with the thick pale green avocado sauce — be generous, let it drip over the sides and pool into the slaw. Serve immediately, while the seafood is still warm and the slaw is cool and crunchy.

💡 Stella’s Pro Tip: For the most dramatic “drip” effect, spoon the avocado sauce into a squeeze bottle or a ziplock bag with the corner snipped off. Drizzle in a zigzag pattern over the seafood — it makes every plate Instagram-ready.

Step	Action	Duration	Key Visual Cue
1	Pat seafood dry, season, butterfly lobster	5 minutes	Seasoning evenly coats the surface
2	Whisk garlic butter, reserve 2 tbsp	3 minutes	Butter is fragrant and slightly frothy
3	Brush and bake at 425°F	10–13 minutes	Lobster opaque, scallops golden at edges
4	Toss slaw, blend avocado drip	5 minutes	Slaw is vibrant purple; sauce is thick and pale green
5	Assemble and drizzle with avocado drip	2 minutes	Avocado sauce drips over the seafood

Serving & Presentation

This is a dish that begs to be seen — and eaten — immediately. I love serving it on a wide, shallow bowl or a rimmed plate that catches every bit of the avocado drip. Start with a generous handful of the lime-tossed purple cabbage slaw, creating a nest for the seafood. Arrange the scallops in a row or cluster on one side, and place the lobster tail on the other, with the butterflied meat facing up so everyone can see that gorgeous golden surface. Drizzle the reserved garlic butter over the top, then finish with the avocado drip in a zigzag pattern. A sprinkle of fresh parsley or microgreens adds a pop of green, and a wedge of lime on the side lets guests add extra brightness if they want.

In my NYC kitchen, I often serve this with warm crusty bread or buttered rice to soak up the avocado sauce and garlic butter pooled at the bottom of the bowl. It’s the kind of meal that feels indulgent but comes together in half an hour — perfect for a date night at home, a special weekend dinner, or even a small dinner party where you want to impress without stress. I learned in Paris that plating is about contrast — colors, textures, heights — and this dish delivers on every level.

Growing up in Morocco, we often ate seafood with a side of warm bread and a simple salad. This recipe nods to that tradition while adding the creamy, tangy avocado drip that’s pure modern NYC. It’s a bridge between the two worlds I love, and every time I serve it, I feel my mother’s kitchen and my Parisian training coming together on one plate.

Pairing Type	Suggestions	Why It Works
Side Dish	Crusty sourdough, buttered jasmine rice, roasted asparagus	Soaks up the avocado drip and garlic butter; adds carb comfort
Sauce / Dip	Extra avocado drip, melted butter with lemon, harissa yogurt	Harissa yogurt adds a North African spicy-tangy note
Beverage	Crisp Sauvignon Blanc, dry rosé, sparkling water with lime	Acidity cuts through the butter richness
Garnish	Fresh parsley, microgreens, lime wedges, edible flowers	Adds color and freshness; lime brightens every bite

Make-Ahead, Storage & Reheating

This sheet pan lobster tail recipe is best enjoyed fresh out of the oven, but I know life gets busy — and I’ve definitely made extra on purpose so I can enjoy it the next day. Here’s how I store and reheat leftovers in my own NYC kitchen, tested over many late-night dinners after a long day of recipe testing.

Method	Container	Duration	Reheating Tip
Refrigerator	Airtight container, seafood separate from slaw and sauce	Up to 2 days	Reheat seafood gently at 300°F for 5–7 min; don’t microwave
Freezer	Freezer-safe bag, seafood only (no slaw or sauce)	Up to 1 month	Thaw overnight in fridge, then reheat at 325°F for 8–10 min
Make-Ahead	Slaw and sauce in separate containers	Slaw 1 day ahead, sauce 1 day ahead	Assemble just before serving; stir sauce before drizzling

Here’s my honest take from many leftover experiments: the scallops and lobster are still delicious the next day, but they’ll never be quite as glorious as straight from the oven. The key to reheating is low and slow — I pop them in a 300°F oven for about 5 to 7 minutes, covered loosely with foil so they don’t dry out. The slaw should always be made fresh (it loses its crunch after a few hours), but you can prep the cabbage and lime juice in advance and toss just before eating. The avocado sauce keeps well for a day if you press plastic wrap directly onto the surface to prevent browning. Give it a good stir before using. ⚠️ Common Mistake to Avoid: Never reheat seafood in the microwave — it turns rubbery instantly. A gentle oven reheat is your best friend.

Variations & Easy Swaps

One of the things I love most about this easy lobster scallop dinner is how adaptable it is. Whether you’re cooking for someone with dietary restrictions, or you just want to switch things up with what’s in season at the Union Square market, these variations have all been tested in my kitchen. Each one keeps the soul of the recipe while letting you make it your own.

Variation	Key Change	Best For	Difficulty Impact
Spicy Harissa Garlic Butter	Add 1 tbsp harissa paste to the garlic butter	North African flavor lovers; adds heat and depth	Easy (no extra steps)
Dairy-Free / Paleo	Use ghee or olive oil instead of butter; coconut cream in drip	Dairy-free or paleo diets	Easy (simple swaps)
Citrus-Herb Slaw	Add orange zest, cilantro, and mint to the slaw	Bright, fresh summer meal	Easy (adds 2 minutes)

Spicy Harissa Garlic Butter Variation

This is my favorite variation and a direct nod to my Moroccan roots. Stir 1 tablespoon of harissa paste (I buy the New York Shuk brand from my local market) into the garlic butter before brushing. The harissa adds a warm, smoky heat that pairs beautifully with the sweet lobster and scallops. It doesn’t make the dish fiery — just deeply flavorful, with a subtle kick that builds as you eat. If you can’t find harissa, use ½ teaspoon of Aleppo pepper flakes or a pinch of cayenne. The rest of the recipe stays exactly the same, including the avocado drip, which cools the heat beautifully.

Dairy-Free / Paleo Variation

For a dairy-free version that doesn’t sacrifice richness, replace the butter with ghee (which is lactose-free) or a high-quality extra-virgin olive oil. The garlic and lemon still shine, and the seafood browns beautifully. In the avocado drip, swap the sour cream for full-fat coconut cream — it adds a subtle tropical sweetness that complements the lime and avocado. I tested this with my friend who’s dairy-free, and she said it was the best seafood she’d had in months. Note: The sauce will be slightly thinner, so add an extra tablespoon of avocado if you want it thicker.

Citrus-Herb Slaw Variation

When I find beautiful organic oranges at the Union Square Greenmarket in winter, I love adding orange zest and a handful of fresh cilantro and mint to the cabbage slaw. The orange zest adds a bright, floral note that echoes the lime juice, while the herbs bring freshness. This variation is especially gorgeous on the plate — the green herbs against the purple cabbage and pale green avocado sauce is a visual stunner. It’s also a great way to use up leftover herbs you have in the fridge.
