This baked spaghetti recipe is a cozy, cheesy comfort food classic made with ground beef, marinara sauce, and three kinds of cheese baked to golden perfection.

Ingredients

Scale
  • 1 pound uncooked spaghetti
  • 1 pound lean ground beef
  • 1/2 medium onion, chopped
  • 1/2 teaspoon dried oregano or Italian seasoning
  • 1/2 teaspoon crushed red pepper flakes (optional)
  • 4 cloves garlic, minced
  • 4 cups marinara sauce
  • Salt & pepper to taste
  • 1 cup shredded mozzarella
  • 1 cup shredded cheddar
  • 1 cup freshly grated parmesan cheese
  • Chopped fresh parsley (optional, to taste)

Instructions

1. Preheat your oven to 375°F and move the rack to the top third of the oven.

2. Boil a large pot of salted water for the spaghetti. Cook it for 2 minutes less than the package directions. Drain and add the pasta to a 9×13-inch baking dish.

3. In a skillet over medium-high heat, add ground beef, chopped onion, oregano, and red pepper flakes. Cook until the meat is browned and the onion is tender, about 10 minutes. Spoon out excess fat if needed.

4. Stir in the minced garlic and cook for 1 minute, then add the marinara sauce. Simmer for a few minutes until warmed through. Season with salt and pepper to taste.

5. Pour the beef and sauce mixture over the cooked spaghetti. Toss until the pasta is evenly coated and smooth the top into an even layer.

6. Sprinkle mozzarella, cheddar, and parmesan cheese evenly over the top.

7. Bake uncovered for 20 minutes, then broil for a few minutes to brown the cheese if desired. Watch carefully to avoid burning.

8. Let the casserole sit for 5-10 minutes before slicing and serving.

9. Garnish with chopped fresh parsley if desired.

Notes

This recipe serves 6 to 8 people depending on portion size.

For a shortcut, use a pre-shredded mozzarella and cheddar blend.

Freshly grated cheese will melt more smoothly and give better flavor.

Use one 24 oz jar of marinara sauce plus a bit from a second jar to get the full 4 cups needed.
