Tips for Making This Spaghetti Bake

  • For a leaner option, opt for ground chicken or ground turkey. For more flavor, you can even use crumbled Italian sausage
  • Make sure your spaghetti is cooked al dente, as the pasta tends to cook a little bit more in the oven and you don’t want them to get mushy. 
  • You can also add veggies to this spaghetti pasta bake, like mushrooms, green bell peppers, diced zucchini or whatever you feel like it.

  • 1 pound lean ground beef
  • 1 small onion, chopped
  • 1 jar (24 ounce) spaghetti sauce, (any kind)
  • cups water, divided
  • 2 teaspoons Italian seasoning
  • 2 teaspoons garlic powder
  • teaspoons salt
  • 1 teaspoon black pepper
  • 8 ounces uncooked spaghetti noodles
  • ¾ cup shredded mozzarella cheese
  • ¼ cup grated Parmesan cheese



  • In a large skillet, cook and crumble ground beef and onion over medium heat until beef is no longer pink. Drain and return to skillet. Wipe skillet if needed.
  • To the ground beef, add spaghetti sauce, 1 cup water, Italian seasoning, garlic powder, salt, and pepper. Stir and bring mixture to a boil. Reduce heat to low and simmer for 5 minutes, stirring occasionally.
  • While meat sauce is simmering, preheat oven to 350°F. Lightly spray a 9x13-inch baking dish with cooking spray. Break spaghetti noodles into thirds and place onto bottom of dish. Pour remaining ½ cup water over noodles.
  • Spread meat mixture over noodles. Tightly cover dish with aluminum foil and bake for 40 minutes. Uncover dish, sprinkle with mozzarella and Parmesan cheese and bake for an additional 10 minutes, uncovered, until cheese as melted.
  • Remove from oven and toss before serving. Garnish with additional cheese, if desired.


  • The meat sauce may seem too watered down, but it should be like that, as it will need the extra liquid to cook the noodles once in the oven.
