Ingredients for Baked Spaghetti

  • Meat: Use ground beef, Italian sausage, or a combination of the two. For a leaner option, ground turkey or turkey sausage can be used.
  • Aromatics: Onion, garlic & green pepper add flavor to the sauce.
  • Sauce: Use your favorite brand of pasta sauce or marinara sauce and add in diced tomatoes and Italian Seasoning for extra flavor
  • Pasta: Since this is a baked spaghetti recipe, I used spaghetti noodles, but you can swap it for any long pasta or whole wheat spaghetti.
  • Cheese: A mix of mozzarella and parmesan add a delicious topping. Pre-shredded cheese works just fine in this recipe.

Holly’s Tips

Baked spaghetti is perfect for lasagna lovers looking for a quicker option.

  • Ensure the spaghetti is cooked al dente as the noodles cook a bit more in the oven.
  • Add extra veggies to the sauce. Try sliced mushrooms, shredded zucchini or carrots.  
  • You can adjust this to your liking and add more or less sauce if you’d prefer.

Feeling Fancy? Garnish this recipe with fresh herbs like basil or parsley before serving.

How to Prep Ahead

  • Prepare as directed and refrigerate for up to 48 hours. Remove it from the fridge at least 30 minutes before baking and bake for about 35 to 40 minutes or until hot in the center.
  • Bake the casserole uncovered 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.
