Step-by-Step Instructions for Casserole Lasagna
1. Cook the Pasta
Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Stir occasionally to prevent sticking. Drain and set aside.
2. Brown the Meat and Onions
In a large skillet over medium heat, cook the ground beef and diced onions until the meat is browned and the onions are soft, about 5-7 minutes. Stir frequently to break up the beef into crumbles. Drain any excess fat.
3. Add the Garlic and Sauce
Reduce heat to low and stir in half the minced garlic, marinara sauce, Italian seasoning, salt, and half of the black pepper. Let the sauce simmer for about 5 minutes, allowing the flavors to meld together.
4. Prepare the Ricotta Mixture
In a mixing bowl, combine ricotta cheese, egg, parsley, remaining garlic, and half the Parmesan cheese. Stir until fully incorporated and smooth.
5. Assemble the Casserole
In a greased 9×13 baking dish, spread half of the cooked pasta evenly. Pour half of the meat sauce over the pasta and spread it out. Spoon dollops of the ricotta mixture over the sauce, followed by a generous layer of mozzarella cheese. Repeat the layers with the remaining ingredients, finishing with a layer of mozzarella and Parmesan cheese on top.
6. Bake
Cover the dish with aluminum foil and bake in a preheated 350°F oven for 30 minutes. Remove the foil and bake uncovered for another 5-10 minutes, or until the cheese is melted and bubbly.
7. Garnish and Serve
Let the casserole rest for 10 minutes before serving to allow it to set. Garnish with fresh basil for an extra pop of flavor and color.
Best Paired With
- Garlic bread – A crispy, buttery side that’s perfect for scooping up extra sauce.
- Side salad – A light and fresh contrast to the rich, cheesy casserole.
- Roasted vegetables – Adds a wholesome and nutritious balance to the meal.
Storage and Serving
Refrigerate leftovers in an airtight container for up to 4 days. Freeze for up to 3 months. Reheat in the oven for best results.
Tips for Success
- Cook the pasta just until al dente to prevent mushiness.
- Use freshly grated cheese for better melting and texture.
Substitutes and Variations
- Ground turkey or chicken for a lighter option.
- Cottage cheese instead of ricotta for a different texture.
- Gluten-free pasta for a GF-friendly version.
