Ingredients
Scale
- 1 pound (450 g) ground beef (8590% lean) or a mix of beef and Italian sausage
- 1 medium yellow onion, finely diced
- 4 cloves garlic, minced
- 1 can (28 ounces/800 g) crushed tomatoes
- 1 can (15 ounces/425 g) tomato sauce
- 2 tablespoons tomato paste
- 1 teaspoon sugar (optional, to balance acidity)
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- ½ teaspoon dried thyme or Italian seasoning
- ½ teaspoon red pepper flakes (optional, for mild heat)
- Salt and black pepper, to taste
- 2 tablespoons olive oil
- 12 lasagna noodles (regular or no-boil)
- 15 ounces (425 g) ricotta cheese
- 1 large egg
- ½ cup grated Parmesan cheese, plus extra for topping
- 2 tablespoons chopped fresh parsley, plus more for garnish (or 1 teaspoon dried)
- 34 cups shredded mozzarella cheese
- Water for boiling noodles (if using regular)
Instructions
- Prep the oven and pan: Preheat the oven to 375°F (190°C). Lightly oil a 9×13-inch baking dish or similar casserole pan.
- Cook the noodles (if not using no-boil): Bring a large pot of salted water to a boil.Cook lasagna noodles until very al dente, about 2 minutes less than package time. Drain and lay flat on a lightly oiled sheet to prevent sticking.
- Brown the meat: Heat olive oil in a large skillet or pot over medium-high heat. Add ground beef (and sausage if using) and cook, breaking it up, until browned and no longer pink.Drain excess fat if needed.
- Sauté aromatics: Add onion and cook until softened, about 45 minutes. Stir in garlic and cook 30 seconds until fragrant.
- Build the sauce: Stir in crushed tomatoes, tomato sauce, and tomato paste. Add oregano, basil, thyme, red pepper flakes (if using), sugar (if needed), and a generous pinch of salt and pepper.Reduce heat and simmer 1520 minutes, stirring occasionally. Taste and adjust seasoning.
- Mix the ricotta layer: In a bowl, combine ricotta, egg, Parmesan, parsley, a pinch of salt, and a few grinds of black pepper. Mix until smooth.
- Layer the lasagna: Spread a thin layer of sauce on the bottom of the baking dish.Add a layer of noodles, slightly overlapping.
- First layer: Spread one-third of the ricotta mixture over the noodles. Sprinkle with mozzarella. Spoon sauce over the top.
- Repeat layers: Add another layer of noodles, then ricotta, mozzarella, and sauce.Repeat for a total of three layers, ending with sauce on top.
- Finish with cheese: Sprinkle remaining mozzarella and a handful of Parmesan over the top. Cover the pan loosely with foil, tenting it so the cheese doesnt stick.
- Bake: Bake covered for 25 minutes. Remove foil and bake another 1520 minutes, until the top is bubbly and lightly golden.
- Rest before slicing: Let the lasagna rest for at least 1520 minutes.This helps it set, making cleaner slices and better texture.
- Serve: Garnish with extra parsley and a little Parmesan. Slice and serve warm.
