Ingredients

Scale

Main Ingredients

  • 16 ounces uncooked spaghetti
  • 16 ounces jar pasta sauce
  • 3 cups water
  • 1 teaspoon oregano or Italian seasoning
  • 1 teaspoon salt (adjust to taste)
  • 1 teaspoon black pepper (adjust to taste)
  • 5 cloves garlic, minced
  • 1 onion, thinly sliced
  • 2 tablespoons olive oil
  • 1 cup shredded mozzarella cheese

Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius) to ensure it’s at the correct temperature before placing the baking dish inside.
  2. Combine Ingredients: In a large baking dish (approximately 11×7 inches), add the uncooked spaghetti, pasta sauce, water, oregano or Italian seasoning, salt, black pepper, minced garlic, sliced onion, and olive oil. Stir well to evenly distribute the ingredients and make sure the pasta is submerged in the liquid.
  3. Bake Covered: Cover the baking dish tightly with foil and bake in the preheated oven for 45 minutes. Around 20-25 minutes into baking, remove the dish carefully and give the mixture a good stir to prevent the pasta from sticking and to ensure even cooking.
  4. Add Cheese: After the 45 minutes, remove the foil and sprinkle the shredded mozzarella cheese evenly over the top of the pasta.
  5. Bake Uncovered: Return the baking dish to the oven and bake uncovered for another 8-10 minutes, or until the cheese is bubbly, melted, and slightly golden.
  6. Serve: Remove from the oven and let it cool for a few minutes before serving. Enjoy your cheesy, flavorful oven baked spaghetti!

Notes

  • This recipe is designed for an approximately 11×7 inch baking dish.
  • For a meatier version, cooked ground beef can be added to the pasta mixture before baking.
  • Stirring the pasta halfway through baking is essential to prevent sticking and ensure even cooking.
  • Adjust salt and pepper to taste according to your preference.
