How to Make Baked Spaghetti Casserole

Step 1: Prepare the Pasta

Start by boiling the spaghetti until it’s just al dente, usually about 8 minutes. Drain the pasta and toss it lightly with a bit of olive oil to prevent sticking while you prepare the rest.

Step 2: Cook the Meat and Aromatics

In a large skillet, heat olive oil over medium heat, then sauté chopped onions and garlic until fragrant and translucent. Add ground beef or sausage and cook until browned and thoroughly cooked, breaking it up into small pieces as it cooks.

Step 3: Mix in Sauce and Seasonings

Pour the marinara sauce into the skillet with the meat mixture and add Italian seasoning, salt, and pepper. Let it simmer for a few minutes to combine all the flavors wonderfully.

Step 4: Combine Pasta, Cheese, and Sauce

In a large bowl, gently mix the cooked spaghetti with the meat sauce and dollops of ricotta cheese. This ensures every bite is creamy and flavorful.

Step 5: Assemble the Casserole

Transfer half of the spaghetti mixture into a greased baking dish. Sprinkle a generous layer of mozzarella and parmesan cheese. Add the remaining spaghetti on top, then finish with another layer of cheese for that golden, bubbly crust.

Step 6: Bake to Perfection

Bake the casserole at 375°F (190°C) for about 25-30 minutes or until the cheese is melted and slightly golden. Let it cool for a few minutes before serving to help it set.

Pro Tips for Making Baked Spaghetti Casserole

• Don’t overcook the pasta: Cook spaghetti al dente to prevent it from becoming mushy after baking.
• Drain excess fat: After browning the meat, drain any leftover fat to keep the casserole from becoming greasy.
• Use a mix of cheeses: Combining mozzarella, ricotta, and parmesan adds creaminess, gooeyness, and sharp flavor for a well-rounded taste.
• Let it rest: Allow the casserole to sit for 5-10 minutes after baking so it firms up and slices more cleanly.
• Customize seasoning: Taste the sauce before baking and adjust herbs, salt, and pepper to suit your preference.

How to Serve Baked Spaghetti Casserole

Top your baked spaghetti casserole with fresh chopped basil or parsley to add a pop of color and herbal brightness. A light sprinkle of crushed red pepper flakes can bring a subtle heat if desired.

Side Dishes

This casserole pairs beautifully with a crisp green salad dressed in tangy vinaigrette to balance the richness. Garlic bread or warm dinner rolls are perfect for soaking up any extra sauce left on the plate.

Creative Ways to Present
