How to Make Baked Pasta Casserole
1. Cook the Pasta
Preheat the oven to 375°F (190°C). Bring a large pot of salted water to a boil. Cook the pasta for about 2 minutes less than the package directions recommend. Drain well.
Cooking the pasta slightly less than fully done helps prevent it from becoming too soft while baking.
2. Prepare the Tomato Sauce
Heat olive oil in a large skillet over medium heat. Add the finely diced onion and sauté until softened.
Add the minced garlic and dried oregano. Cook briefly until fragrant, being careful not to burn the garlic.
3. Add the Marinara
Pour the marinara sauce or crushed tomatoes into the skillet. Stir everything together and simmer for about 2 minutes.
Taste and adjust with salt and black pepper as needed.
4. Combine the Pasta and Sauce
Add the drained pasta to the skillet. Toss gently until every piece is coated with the tomato sauce and seasonings.
5. Assemble the Casserole
Transfer the pasta mixture to a 9×13-inch baking dish and spread it evenly.
Sprinkle the shredded mozzarella over the top, followed by the freshly grated Parmesan cheese.
6. Bake
Place the casserole in the preheated oven and bake for 20–25 minutes, or until the cheese is melted, bubbly, and golden brown.
7. Rest and Serve
Remove the casserole from the oven and let it rest for about 5 minutes. Garnish with fresh basil or parsley and serve warm.
This step-by-step recipe creates tender pasta, flavorful tomato sauce, and an irresistibly cheesy baked topping.
Pro Tips and Cooking Secrets
- Don’t overcook the pasta: It continues cooking in the oven, so slightly undercooking it gives the best texture.
- Use freshly grated Parmesan: It melts and browns beautifully.
- Don’t overcrowd the dish: Spread the pasta evenly for consistent baking.
- Season every layer: Proper seasoning makes a simple pasta casserole much more flavorful.
- Let it rest: Five minutes allows the cheese and sauce to settle before serving.
- For extra browning: Place the casserole under the broiler for the final 1–2 minutes, watching carefully.
Serving Suggestions
Serve this cheesy baked pasta with a simple side salad and warm garlic bread for a complete dinner.
It also pairs nicely with:
- Roasted vegetables
- Steamed broccoli
- Garlic bread

For a heartier meal, add cooked chicken, ground beef, or sausage to the casserole.
How to Store Baked Pasta Casserole
Refrigerator: Store leftovers in an airtight container or cover the baking dish tightly. Refrigerate for up to 4 days.
Freezer: Allow the casserole to cool completely, then freeze in an airtight freezer-safe container for up to 2–3 months.
Make-ahead: Assemble the casserole, cover it tightly, and refrigerate before baking. When ready, bake until heated through and the cheese is bubbly.
Reheating: Reheat individual portions in the microwave or warm the casserole in a covered oven-safe dish until hot.
If the pasta seems dry after refrigeration, add a small spoonful of marinara sauce before reheating.
