Ingredients You’ll Need
You only need a handful of pantry staples and a few fresh ingredients to whip up this Easy Italian Casserole Recipe, and each one earns its place! Every component adds its own special touch, whether it’s depth of flavor, glorious meltiness, or that irresistible golden finish.
- Ground beef or Italian sausage: Choose your favorite for a robust, savory base — either gives the casserole its meaty heart.
- Onion: Chopped onion sautés until sweet and soft, building big flavor right from the start.
- Marinara or pasta sauce: The sauce binds everything together with tangy, herby Italian goodness.
- Diced tomatoes: Drained to avoid excess moisture, they bring brightness and texture.
- Italian seasoning: A mix of classic herbs that instantly gives the dish its signature aroma.
- Uncooked pasta: Penne or rotini hold the sauce and cheese in every bite — pick your favorite shape.
- Shredded mozzarella cheese: For that gooey, stretchy topping that everyone loves.
- Grated Parmesan cheese: Adds salty, nutty depth to the cheesy layers.

How to Make Easy Italian Casserole Recipe
Step 1: Prep and Preheat
Set yourself up for success by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish, which helps make serving (and cleanup!) a breeze. This little head start sets the stage for cheesy perfection later.
Step 2: Brown the Meat and Onion
In a large skillet over medium heat, cook your ground beef or Italian sausage along with the chopped onion. Sauté until the meat is browned and crumbly and the onions are soft and fragrant. Be sure to drain off any excess grease so your Easy Italian Casserole Recipe doesn’t end up oily.
Step 3: Simmer the Sauce
Once your meat and onions are ready, stir in the marinara or pasta sauce, drained diced tomatoes, Italian seasoning, and a good dash of salt and pepper. Let this mixture simmer together for about five minutes, just to let the flavors mingle and develop that cozy, saucy richness.
Step 4: Cook the Pasta
Meanwhile, cook your pasta in a pot of salted, boiling water until just al dente — it’ll finish up in the oven, so don’t let it get mushy! Drain well so your casserole bakes up beautifully instead of soggy.
Step 5: Layer Everything Up
Combine your drained pasta and meaty tomato sauce until everything is thoroughly coated. Now comes the fun part: spread half the mixture into your prepared baking dish, dollop ricotta cheese over (if using), then shower on half the mozzarella and Parmesan. Top with the remaining pasta mixture and finish off with the rest of your cheese for a mouthwatering golden crown.
Step 6: Bake to Cheesy Perfection
Slide the dish into the oven and bake for 20 to 25 minutes, or until it’s bubbly all over and the cheese is gloriously melted and golden brown. Let the casserole sit for about five minutes before serving — it sets up a bit, making for neat, satisfying slices.
How to Serve Easy Italian Casserole Recipe

Garnishes
A sprinkle of fresh basil or parsley just before serving gives your Easy Italian Casserole Recipe a restaurant-quality finishing touch. Those pops of green freshen up every bite and make the whole dish look extra inviting.
Side Dishes
This casserole is fantastic alongside a bright, tangy salad (think arugula or mixed greens tossed with vinaigrette) or served with crisp garlic bread for dunking. Roasted broccoli or sautéed spinach can add extra color and nutrition, making the whole meal sing.
Creative Ways to Present
For family-style comfort, serve straight from the baking dish at the table — those bubbling edges are irresistible. If you’re prepping for a dinner party or potluck, try using individual ramekins for personal portions of casserole, or top each slice with a swirl of pesto for extra flair.
Make Ahead and Storage
Storing Leftovers
Leftover Easy Italian Casserole Recipe keeps beautifully! Cover the cooled casserole tightly or transfer to an airtight container and refrigerate for up to 4 days. The flavors deepen overnight, so tomorrow’s lunch might taste even better than tonight’s dinner.
Freezing
This recipe makes an excellent freezer meal. Assemble the casserole right up to the baking step, then cover well with foil and freeze for up to 3 months. Thaw overnight in the fridge when you’re ready to bake, and add a few extra minutes of oven time if needed.
Reheating
For best results, reheat the casserole (whole or in portions) in a 350°F oven until hot and bubbly, or microwave slices for a quick lunch. Add a fresh sprinkle of cheese or herbs before serving to bring back that just-baked flavor.
FAQs
Can I use a different type Main Course
Absolutely! Swap in ground turkey, chicken, or even plant-based crumbles if you want a lighter or vegetarian take. Just keep in mind that different meats may need slight seasoning tweaks.
Do I need to use ricotta cheese, or is it optional?
Ricotta cheese is optional but highly recommended for that classic creamy texture. If you prefer, you can skip it or substitute cottage cheese, or simply add extra mozzarella for more gooey goodness.
What vegetables can I add to the casserole?
Diced bell peppers, chopped spinach, or sliced mushrooms are all fantastic additions. They’ll blend right into the sauce and boost the nutrition without overpowering the Italian flair.
How do I prevent my casserole from coming out dry?
Make sure your sauce is plentiful and your pasta is cooked just until al dente. A layer of cheese on top also helps seal in moisture while baking for a perfectly tender result.
Can I assemble this Easy Italian Casserole Recipe ahead of time?
Definitely! Prepare the entire casserole right up to the baking step, cover, and refrigerate for up to 24 hours. When ready to bake, add a couple of extra minutes to the cooking time if baking straight from the fridge.
