Leftover Spaghetti Bake with Cheese: Easy Recipe!

A delicious and comforting way to repurpose leftover pasta into a cheesy, oven-baked casserole featuring a creamy ricotta blend and melted mozzarella.

Ingredients

Scale
  • 4 cups leftover cooked spaghetti
  • 2 cups marinara sauce
  • 1 cup ricotta cheese
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 2 large eggs
  • 1 teaspoon dried oregano
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon red pepper flakes (optional)
  • Fresh basil leaves for garnish (optional)

Instructions

  1. Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish.
  2. In a large mixing bowl, stir together the leftover spaghetti and marinara sauce until well-coated.
  3. In a separate bowl, whisk together the ricotta, half of the mozzarella, Parmesan, eggs, oregano, garlic powder, salt, pepper, and red pepper flakes until creamy.
  4. Gently fold the ricotta mixture into the sauced spaghetti.
  5. Spread the mixture evenly into the prepared baking dish and top with the remaining mozzarella cheese.
  6. Bake for 25 to 30 minutes until the cheese is bubbly and golden. (Optional: broil for 1-2 minutes for extra crispiness).
  7. Let the dish rest for 5 to 10 minutes before slicing. Garnish with fresh basil and serve.

Notes

  • Ensure the spaghetti is broken up slightly if it has clumped together in the fridge.
  • You can add cooked ground beef or Italian sausage to the sauce for extra protein.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days.
