Ingredients
- 12 ounces dried spaghetti (or other long pasta)
- 1 to 1.5 pounds ground beef or turkey (can substitute Italian sausage or plant-based meat for variety)
- 1 medium onion, finely diced
- 2 teaspoons minced garlic (approximately 2 cloves)
- 24 ounces jarred pasta sauce (marinara or tomato-basil recommended)
- 1/2 teaspoon dried Italian seasoning (or a blend of oregano and basil)
- 1/2 teaspoon salt (adjust to taste)
- 1/4 teaspoon ground black pepper
- 1 cup cottage cheese (or ricotta cheese for a richer flavor)
- 1 egg, lightly beaten
- 2 cups shredded mozzarella cheese (divided)
- 1/2 cup grated Parmesan cheese
- Nonstick cooking spray or olive oil (for greasing the baking dish)
- Chopped fresh parsley or basil (optional, for garnish)
Directions
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick spray or olive oil.
- Cook the spaghetti according to package instructions until al dente. Drain well and set aside.
- Prepare the meat sauce: In a large skillet over medium heat, cook the ground beef (or turkey/sausage). Add diced onion and cook until softened, about 3-5 minutes. Stir in minced garlic and cook until fragrant. Drain excess fat if needed.
- Pour in the pasta sauce, Italian seasoning, salt, and pepper. Let simmer for 5-10 minutes, stirring occasionally, until flavors meld.
- Mix the cheese layer: In a medium bowl, combine cottage cheese (or ricotta), beaten egg, 1 cup of the mozzarella, and half of the Parmesan. Mix until well blended.
- In the bottom of the prepared baking dish, layer half of the cooked spaghetti. Top with half of the meat sauce, then half of the cheese mixture.
- Repeat the layers: spaghetti, meat sauce, remaining cheese mixture.
- Sprinkle the top with the remaining 1 cup of mozzarella and the rest of the Parmesan cheese.
- Bake uncovered for 30-35 minutes, or until the casserole is hot and the cheese is golden and bubbly.
- Let rest for 5-10 minutes before slicing and serving. If desired, garnish with fresh parsley or basil.
Serving Suggestions and Variations
- Vegetarian Option: Omit the meat and stir in sautéed mushrooms, zucchini, spinach, or bell peppers for a veggie-packed version.
- Gluten-Free Swap: Use your favorite gluten-free spaghetti noodles to make the casserole gluten-free.
- Different Cheeses: Swap out mozzarella for provolone or add a sprinkle of sharp cheddar for extra flavor.
- Spice It Up: Add hot pepper flakes or use spicy Italian sausage for extra kick.
- Make-Ahead: Assemble the casserole up to a day in advance. Cover and refrigerate, then bake when ready.
- Freezer Friendly: Freeze the assembled casserole (unbaked) for up to two months. Thaw in the fridge overnight and bake as directed, adding extra time if needed.

Tips for the Perfect Spaghetti Casserole
- Drain the Pasta: After cooking, make sure the spaghetti is well drained. Excess water can make the casserole runny.
- Brown the Meat Thoroughly: Cooking the meat completely before combining with sauce ensures best texture and flavor.
- Use Good Quality Sauce: A flavorful marinara or tomato-basil pasta sauce enhances the overall taste.
- Rest Before Serving: Allow the casserole to cool for a few minutes after baking. This helps it set for easier slicing.
- Double for a Crowd: This recipe can be doubled and baked in two pans for feeding a large group or for leftovers.

Common Questions
- Can I use different types of pasta?
Absolutely. Spaghetti is traditional, but linguine, fettuccine, or even short pastas like penne work well. Adjust cooking time as needed. - Is it possible to make this casserole ahead?
Yes! Prepare and assemble up to a day in advance. Cover and refrigerate, then bake when ready. You may need to add 10–15 minutes extra bake time if baking from chilled. - How do I keep the casserole from being watery?
Be sure to drain the cooked pasta well before assembling, and simmer the meat sauce until thickened. - What sides go well with baked spaghetti casserole?
Pair it with garlic bread, Caesar salad, steamed green beans, or roasted vegetables for a complete meal. - Can I use cottage cheese instead of ricotta?
Yes, cottage cheese offers a lighter texture and is more affordable, though ricotta provides a richer taste. Both options work nicely in this dish.
