Ingredients Notes

Find the full printable recipe with specific measurements below.
- Pasta: Any medium pasta works for this recipe. I like campanelle pasta, but you can also use bow-tie pasta or penne noodles.
- Ground beef: Use lean ground beef or Italian sausage. For spice you could also try hot Italian sausage.
- Marinara sauce: This is when I like to use homemade marinara. If you prefer a jar of store-bought marinara sauce, use that.
- Cheeses: You’ll need ricotta cheese, freshly grated mozzarella, and Parmesan cheese.
- Aromatics and seasoning: Chopped onion, minced garlic, fresh basil, salt, pepper, and Italian seasoning.
How to Make Lasagna Casserole
Sauté onions in a large pot over medium heat for 3-5 minutes then add garlic. Once onions are tender, add beef and break up while cooking until no longer pink. Drain excess grease.
Stir in the marinara sauce, chopped basil, salt, and pepper. Simmer for 10-15 minutes, then stir in the cooked pasta.


In a medium bowl, mix the ricotta, mozzarella, Parmesan, with Italian seasoning.


Spoon half of the pasta mixture into a preheated 9×13 baking dish and top with dollops of the ricotta mixture. Top with the other half of the pasta mixture then sprinkle with remaining mozzarella and Parmesan.
Bake in a preheated 350°F oven for 20-25 minutes until the cheese is melted and bubbly! Serve garnished with fresh basil or parsley (I’m partial to basil here) and enjoy!


Recipe Tips
- Cook noodles to al dente so they don’t overcook in the oven.
- Grated fresh mozzarella is the way to go. It melts much more easily.
- Not a must, but serving with fresh herbs sprinkled on top really takes it up a notch.
- Let the lasagna pasta bake sit for a few minutes before serving, so it’s not hot and soupy!

Cheese: Freshly grated cheese melts better than the pre-shredded.
Make-ahead: To make in advance, simply assemble, cover with foil, and place in the fridge. The dish will keep in the fridge for about 2 days. When ready to bake, remove the foil and bake at 350°F for 35 to 45 minutes.
Reheating leftovers: Loosely cover with foil and cook in the oven at 350°F until warmed throughout. The foil helps to keep the pasta from drying out. I’ve found that it takes about 15 minutes to heat all the way through.

Recipe FAQs
Lazy man lasagna is great for meal prep because you can assemble it completely, cover it in foil, and keep it refrigerated for up to 2 days until you’re ready to bake it.
Keep leftovers stored in an airtight container for up to 4 days in the fridge.
If there’s enough to warrant using the oven, do that! Tent it loosely with foil and reheat for about 15 minutes in a 350°F oven. The foil helps prevent it from drying out.
If it’s just a small portion, use the microwave, but DO NOT tent with foil!
