Tomato paste
Italian seasoning
Dried oregano
Garlic powder
Fine sea salt
Black pepper
Mozzarella cheese, shredded
Cheddar cheese, shredded
Parmesan cheese, grated
Cream cheese (optional)
Fresh parsley, chopped

Directions

I preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
I cook the spaghetti until al dente according to the package directions, then drain it.
I heat the olive oil in a large skillet and cook the ground beef or Italian sausage until browned.
I add the diced onion and garlic, cooking until they become soft and fragrant.
I stir in the marinara sauce, tomato paste, Italian seasoning, oregano, garlic powder, salt, and pepper, then let the sauce simmer for about 10 minutes.
I toss the cooked spaghetti with part of the shredded mozzarella and cheddar cheese.
I spread half of the spaghetti into the prepared baking dish, top it with half of the meat sauce, and repeat the layers.
I sprinkle the remaining mozzarella, cheddar, and Parmesan cheese evenly over the top.
I bake for 20–25 minutes, or until the cheese is melted, bubbly, and lightly golden.
I let the spaghetti rest for about 10 minutes before garnishing it with fresh parsley and serving.

Variations

I use spicy Italian sausage when I want a little more heat.
I mix ricotta cheese into the pasta layers for a lasagna-inspired twist.

Storage/Reheating

I store leftover cheesy spaghetti in an airtight container in the refrigerator for up to 4 days. For longer storage, I freeze individual portions or the entire casserole for up to 3 months. When I’m ready to enjoy it again, I reheat it in a 350°F (175°C) oven until heated through or warm individual servings in the microwave. If needed, I add a splash of marinara sauce to keep the pasta moist.

FAQs

Can I make this recipe ahead of time?

Yes. I assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking.

What cheeses work best?

I like using a combination of mozzarella, cheddar, and Parmesan because they create the perfect balance of creaminess and flavor.

Can I freeze baked cheesy spaghetti?

Yes. I let it cool completely, wrap it well, and freeze it for up to 3 months before thawing and reheating.

How do I keep the spaghetti from drying out?

I make sure there is plenty of sauce, and I cover the baking dish with foil for part of the baking time if necessary.
