What is Lasagna Casserole?
Lasagna casserole is essentially a deconstructed version of classic lasagna. Instead of the layered approach, you combine the ingredients in a casserole dish for an easier and quicker method.

You get the same indulgent, satisfying experience but with less fuss, making it perfect for busy weeknights or when you want something quick and comforting.
Ingredients List for Lasagna Casserole
Here’s a breakdown of the ingredients you’ll need for a delicious lasagna casserole. You can also make substitutions based on your preferences (see Substitutions and Variations section).
For the Casserole:
- 12 oz pasta (rigatoni, penne, or rotini) – These shapes hold the sauce well and are easier to serve in a casserole.
- 1 lb ground beef or Italian sausage – Provides the savory base for the dish.
- 1 medium onion, diced – Adds sweetness and depth to the sauce.
- 3 cloves garlic, minced – Brings aromatic richness to the meat sauce.
- 1 (24 oz) jar of marinara sauce or homemade tomato sauce – The foundation of the lasagna’s sauce.
- 1 (15 oz) container of ricotta cheese – Adds creaminess and texture.
- 2 cups shredded mozzarella cheese – For that gooey, melty top.
- 1 cup grated parmesan cheese – Adds sharpness and depth of flavor.
- 1 large egg – Helps bind the ricotta mixture.
- 2 teaspoons Italian seasoning – A blend of herbs to enhance the sauce.
- Salt and pepper, to taste – For seasoning.
Optional Additions:
- 1 cup chopped spinach – Adds nutrition and color.
- ½ cup ricotta or bechamel sauce – For added creaminess.
- Crushed red pepper flakes – For a little kick of heat.
Substitutions and Variations
One of the great things about lasagna casserole is its versatility. Here are some ways to change up the recipe to suit your tastes or dietary needs:
- Meat: Swap the ground beef or sausage with ground turkey, chicken, or even plant-based crumbles for a vegetarian option.
- Cheese: If you’re not a fan of ricotta, you can use cottage cheese or cream cheese as a substitute. You can also mix and match different types of shredded cheeses—try cheddar or gouda for a different flavor profile.
- Pasta: Any short pasta will work well, like penne, rigatoni, or even rotini. For a gluten-free option, use gluten-free pasta.
- Veggies: Add veggies like mushrooms, zucchini, or bell peppers for extra nutrients and flavor.
- Sauce: For a richer sauce, try using a combination of marinara and alfredo sauce. You can also spice it up with some crushed red pepper or add extra garlic and basil for more depth of flavor.
Step-by-Step Cooking Instructions

Follow these simple instructions to make your lasagna casserole:
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add your pasta of choice and cook according to package instructions until al dente (firm to the bite). Drain and set aside.
Step 2: Prepare the Meat Sauce
While the pasta is cooking, heat a large skillet over medium heat. Add the ground beef or Italian sausage and cook until browned and fully cooked, breaking it up with a spoon. Once cooked, remove excess fat if necessary. Add the diced onion and minced garlic, sautéing until the onion is soft, about 3-5 minutes. Stir in the marinara sauce and Italian seasoning. Simmer the sauce for 10 minutes to allow the flavors to meld. Season with salt and pepper to taste.
Step 3: Prepare the Ricotta Mixture
In a medium bowl, combine the ricotta cheese, parmesan, egg, and a pinch of salt and pepper. Stir until well mixed. For added flavor, you can stir in some chopped spinach or fresh parsley.
Step 4: Assemble the Casserole
Preheat your oven to 375°F (190°C). In a large casserole dish (9x13 inches works well), start by spreading a thin layer of the meat sauce at the bottom. Then, add half of the cooked pasta, followed by half of the ricotta mixture, half of the remaining meat sauce, and a generous sprinkle of mozzarella cheese. Repeat this layering process with the remaining ingredients: pasta, ricotta, sauce, and mozzarella.
Step 5: Bake the Casserole
Cover the casserole dish with foil and bake for 20 minutes. After 20 minutes, remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly, and the top is golden brown.
Step 6: Let it Rest
Once your lasagna casserole is done, remove it from the oven and let it sit for 10 minutes. This allows the dish to set and makes it easier to slice and serve.
How to Cook Lasagna Casserole: A Step-by-Step Guide
Here's a simplified step-by-step guide for making lasagna casserole:
- Cook the pasta until al dente and drain.
- Make the meat sauce by browning the meat and mixing it with onions, garlic, and marinara sauce.
- Prepare the ricotta mixture by combining ricotta, parmesan, and an egg for a creamy filling.
- Layer the ingredients in a casserole dish: meat sauce, pasta, ricotta, and cheese.
- Bake the casserole covered, then uncovered, until the cheese is bubbly and golden.
Common Mistakes to Avoid
- Overcooking the pasta: Make sure to cook the pasta to al dente, as it will continue to cook when baked in the oven. Overcooked pasta can turn mushy in the casserole.
- Skipping the seasoning: Be sure to taste your sauce before assembling the casserole. Adjust the salt, pepper, and herbs to make sure the dish is well-seasoned.
- Not letting it rest: Let the casserole sit for at least 10 minutes before serving to allow it to set and make it easier to serve.
- Using too much sauce: While sauce is great, adding too much can result in a soggy casserole. Use just enough to coat the pasta and meat mixture.
Serving and Presentation Tips
How you serve and present your lasagna casserole can elevate the meal. Here are some ideas:
How to Serve Lasagna Casserole:
- Family-Style: Serve directly from the baking dish, allowing everyone to help themselves. This method is perfect for a casual dinner or potluck.
- Individual Portions: Scoop out neatly cut squares of casserole for individual plates. Garnish with fresh basil or parsley for added color and freshness.
Presentation Ideas for Lasagna Casserole:
- Fresh Garnish: A sprinkle of freshly chopped basil or parsley not only adds color but also a touch of freshness.
- Add Parmesan on Top: Once out of the oven, sprinkle additional grated parmesan cheese on top for a final layer of flavor.
- Serve with Garlic Bread: Nothing complements lasagna like garlic bread. Add a side of toasted garlic bread or a simple salad for a complete meal.
