Baked spaghetti is a perfectly delicious cheesy and meaty pasta dish — turned casserole! It’s the ultimate quick and easy meal that can even be prepped in advance. Baking it involves loading on a bunch of yummy Parmesan and mozzarella which makes the whole thing ooey and gooey with cheese.

Ingredient Notes

  • Spaghetti Pasta: Any brand of spaghetti will work, but make sure to cook it al dente.
  • Olive Oil: Use extra virgin olive oil for the best flavor.
  • Ground Beef: For a leaner option, you can use ground turkey or chicken.
  • White Onion: White onion is mild and sweet, but you can substitute with yellow onion if that’s what you have on hand. Make sure to dice it finely so it softens quickly.
  • Garlic: If you’re out of fresh garlic, you can use 1/2 teaspoon of garlic powder per clove as a substitute.
  • Tomato Paste: Open both ends of the can and push from one side to easily remove all of the tomato paste from the can.
  • Crushed Tomatoes and Tomato Sauce: If you prefer a smoother sauce, you can use all tomato sauce or blend the crushed tomatoes before adding them.
  • Dried Basil and Oregano: These herbs are essential for classic Italian flavor.
  • Parmesan Cheese: Freshly grated Parmesan melts a lot better!
  • Mozzarella Cheese: Shredded mozzarella provides that gooey, cheesy top layer.

Make Ahead Option

To make this dish ahead of time, follow the recipe as instructed. Instead of baking, simply cover it with plastic wrap and place it in the fridge for up to 24 hours. When ready, remove the plastic wrap and proceed with baking as directed in the original recipe.

Storage and Reheating Instructions

Refrigerate leftovers in an airtight container for 3-4 days.

To freeze, fully assembly the casserole and cover the pan well with plastic wrap or an airtight lid and place it in the freezer. You may consider using an aluminum baking dish as it makes storing it easier. It will keep frozen for up to 3 months. Let it thaw in the fridge overnight, then follow the baking instructions as directed in the original recipe.

Reheat in the oven: If you’re reheating a larger portion, cover the dish with foil to prevent the cheese from over-browning. Bake at 350°F (175°C) for about 20-25 minutes, or until heated through.

Reheat in the microwave: For individual servings, microwave on high in 30-second increments, stirring in between, until thoroughly warmed.
