Ingredients List
Gather these simple ingredients to build layers of flavor. I’ve included sensory notes and substitutions to make this recipe your own.
- For the Meatloaf Layer:
- 2 lbs ground beef (85/15 blend) – The slight fat content ensures a juicy, flavorful base. Substitute: Ground turkey or a 50/50 blend of beef and pork for richer flavor.
- 1 cup panko breadcrumbs – Creates a lighter texture than traditional breadcrumbs. Substitute: Gluten-free panko or crushed pork rinds for a low-carb option.
- 2 large eggs – The binding agent that holds everything together.
- 1/2 cup whole milk – Adds moisture and tenderness. Substitute: Buttermilk for a slight tang, or unsweetened almond milk.
- 1 small yellow onion, finely diced – Provides a sweet, aromatic foundation.
- 2 cloves garlic, minced – For that essential savory punch.
- 1/4 cup ketchup + 2 tbsp for topping – Adds sweetness and tang. Substitute: BBQ sauce or tomato paste thinned with a bit of vinegar.
- 1 tbsp Worcestershire sauce – The umami secret weapon.
- 1 tsp smoked paprika – Gives a deep, smoky aroma reminiscent of outdoor grilling.
- Salt and black pepper to taste
- For the Potato & Topping Layer:
- 4 cups prepared mashed potatoes – Use homemade for the best creamy, buttery flavor and texture, or high-quality store-bought to save time. Tip: Ensure they are stiff, not runny.
- 2 cups shredded cheddar cheese – Sharp cheddar provides the best melt and bold flavor. Substitute: A Mexican blend or Monterey Jack for a milder taste.
- 6 slices of bacon, cooked crispy and crumbled – For that irresistible salty, smoky crunch. Substitute: Turkey bacon or chopped ham.
- 2 tbsp chopped fresh chives or parsley – A fresh, colorful garnish that cuts through the richness.
Timing
Compared to the average meatloaf recipe which requires separate preparation and baking times for the meatloaf and sides (often totaling 90+ minutes), this all-in-one casserole method is a significant time-saver. The active prep is streamlined, and the oven does most of the work, freeing you up for other tasks. The result is a complete, balanced meal in nearly the same time it takes to bake a traditional meatloaf alone.

Step-by-Step Instructions
Step 1: Prepare the Meatloaf Base
Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the ground beef, panko breadcrumbs, eggs, milk, diced onion, minced garlic, 1/4 cup ketchup, Worcestershire sauce, smoked paprika, salt, and pepper. Now, here’s my pro tip: use your hands! Yes, get in there and mix until just combined. Overmixing will make the meatloaf layer dense and tough. You want to see the ingredients evenly distributed without squeezing the life out of the meat. Once mixed, press this meatloaf mixture evenly into the bottom of a 9×13 inch baking dish, creating your first savory layer.
Step 2: Assemble the Casserole
Take your prepared mashed potatoes. If they’re cold from the fridge, give them a quick stir to loosen them up. Carefully dollop the mashed potatoes over the entire surface of the meatloaf layer. Using a spoon or offset spatula, gently spread the potatoes into an even layer, sealing the edges. This potato blanket will steam the meatloaf from above, keeping it incredibly moist. Next, take the remaining 2 tablespoons of ketchup and drizzle it in thin lines or swirls over the potato layer. This isn’t just for looks—it adds a caramelized, tangy glaze as it bakes.
Step 3: Bake to Perfection
Place the uncovered casserole dish in the preheated oven. Bake for 40 minutes. You’ll know it’s progressing perfectly when you smell the savory aromas filling your kitchen and see the edges of the meatloaf pulling away slightly from the dish. The potatoes will have set, and the ketchup swirls will be darkened and sticky.
Step 4: The Final Cheesy Touch
Remove the casserole from the oven (carefully—it’s hot!). Immediately sprinkle the two cups of shredded cheddar cheese evenly over the entire top. Return the dish to the oven for just 5-7 more minutes, or until the cheese is fully melted, bubbly, and starting to get those beautiful golden spots. Once out of the oven, let it rest for 5-10 minutes. This crucial step allows the layers to set, making slicing and serving much cleaner. Finally, garnish with the crumbled crispy bacon and fresh chives. The contrast of the hot, melty cheese with the cool, crisp bacon is divine.

Healthier Alternatives
Craving comfort but watching your intake? You can easily adapt this recipe without sacrificing the soul-satisfying flavor.
- Leaner Protein: Swap the ground beef for 93% lean ground turkey or chicken. To prevent dryness, add 1 tablespoon of olive oil to the meat mixture.
- Lighter Potatoes: Use mashed cauliflower or a 50/50 blend of cauliflower and potato. Season well with garlic powder, pepper, and a touch of nutritional yeast for a “cheesy” flavor.
- Reduced-Fat Dairy: Opt for 2% milk and reduced-fat sharp cheddar cheese. The sharpness ensures you still get a big cheese flavor with less fat.
- Lower-Sodium: Use low-sodium ketchup, reduce added salt, and choose lower-sodium bacon or omit it, topping with toasted whole-wheat panko for crunch instead.
Serving Suggestions
This casserole is a complete meal, but a few simple sides can elevate it into a feast:
- Fresh & Crisp: A simple arugula salad with a lemon vinaigrette cuts through the richness perfectly.
- Vegetable Forward: Steamed green beans, roasted broccoli, or glazed carrots add color and nutrition.
- Bread Basket: Warm, crusty dinner rolls or garlic bread are perfect for soaking up any delicious juices.
- For Breakfast: Leftovers reheated with a fried egg on top make an incredible next-morning meal.
Common Mistakes
- Overmixing the Meat: This is the #1 culprit for a tough, dense meatloaf layer. Mix until just combined—no more.
- Using Runny Mashed Potatoes: If your potatoes are too loose, they’ll sink into the meat layer. They should be stiff enough to hold their shape when spread.
- Skipping the Rest Time: Cutting in too soon will cause the cheesy, saucy layers to ooze out. Let it set for clean slices.
- Overbaking Before Adding Cheese: Adding cheese for the full bake time can cause it to burn or become greasy. The final 5-7 minutes is perfect.
Storing Tips
- Refrigeration: Cool completely, then cover tightly with plastic wrap or transfer to an airtight container. It will keep for 3-4 days.
- Freezing: This casserole freezes beautifully! Assemble and bake without the cheese topping. Cool, wrap tightly in foil and plastic, and freeze for up to 3 months. Thaw overnight in the fridge, add cheese, and bake at 375°F until heated through and cheese is melted.
- Reheating: For best results, reheat individual portions in the oven at 350°F (covered) for 15-20 minutes, or until hot. The microwave works in a pinch but can make the potatoes a bit gummy.
