How to Make Baked Spaghetti
Step 1: Preheat the Oven
Preheat your oven to 375°F and adjust the rack to the top third of the oven. This ensures even baking and helps brown the cheese on top.
Step 2: Cook the Spaghetti
Boil salted water in a large pot. Add the spaghetti and cook for 2 minutes less than the package instructions. Drain the spaghetti and transfer it to a 9x13 casserole dish.
Step 3: Brown the Meat
In a skillet, cook the ground beef, chopped onion, oregano, and optional red pepper flakes over medium-high heat. Stir until the beef is browned and the onions are soft, about 5–7 minutes.
Step 4: Add Garlic and Sauce
Stir in the minced garlic and cook for an additional minute. Then, add the marinara sauce to the skillet, stirring until warmed through.
Step 5: Combine the Mixtures
Pour the beef and sauce mixture over the spaghetti in the casserole dish. Toss everything gently to coat the spaghetti evenly. Spread the mixture evenly across the dish.
Step 6: Add the Cheese and Bake
Top the spaghetti mixture with mozzarella, cheddar, and parmesan cheeses. Bake uncovered for 20 minutes until the cheese is melted and bubbly.
Step 7: Broil and Serve
If desired, broil for a couple of minutes to lightly brown the cheese. Let the dish sit for 5–10 minutes before serving. Garnish with fresh parsley if you like.

Pro Tips from My Kitchen
✓ Cook Pasta Al Dente – Make sure to cook your spaghetti al dente, as it will continue to cook in the oven. This prevents it from becoming mushy later.
✓ Use Fresh Ingredients – Fresh garlic and quality marinara sauce truly elevate the flavor. Seek out brands you love or make your sauce from scratch if you can.
✓ Cover While Baking – If you see the cheese browning too quickly while baking, cover the dish with foil for part of the baking time. This allows everything to heat evenly without burning the top.
✓ Cool Before Storing – If you're making this dish ahead, allow it to cool before storing in the fridge. This helps prevent condensation from making it soggy.
✓ Pair with a Salad – Serve baked spaghetti with a fresh green salad for a complete meal. The crisp greens balance the richness of the pasta perfectly.
