Ingredients for Baked Spaghetti

  • Meat: Choose either ground beef or Italian sausage or a combination of the two. For a leaner option, ground turkey is a great option.

  • Sauce: Use your favorite brand of pasta sauce or marinara sauce and add in diced tomatoes and Italian Seasoning for extra flavor
  • Spaghetti: Replace the spaghetti noodles with any long pasta or whole wheat spaghetti.
  • Cheese: The crowning glory. A mix of mozzarella and parmesan brings that gooey, golden finish we all adore.

How to Make Baked Spaghetti

  1. Brown beef and onions. Add veggies and tomato sauce and simmer.
  2. Toss the sauce with cooked spaghetti and transfer it to a baking dish.
  3. Top with cheese and bake!

Holly’s Tips

  • Esure the spaghetti is cooked al dente as the noodles cook a bit more in the oven.
  • Add whatever you like to the sauce, replace green pepper with diced mushrooms or zucchini.  
  • You can easily adjust this to your liking and add more or less sauce if you’d prefer.

Prep Ahead

  • Since the pasta and the sauce are warm when making this dish, bake it for about 25 minutes.
  • If you prep it ahead of time and refrigerate it, it’ll take a bit longer. Remove it from the fridge 30 minutes before baking and bake for about 35 minutes or until hot in the center.
  • The prep can be done the night before and then baked before serving, making this baked spaghetti the perfect potluck dish!
  • Don’t cover the baked spaghetti so the cheese can form a nice crust. Covering it will also make it steam which can overcook the spaghetti.

Just like stuffed shells, this easy recipe is perfectly served with garlic bread and a Caesar salad.
