Baked Spaghetti is a favorite casserole around here!  A quick zesty meat sauce is combined with tomatoes and spaghetti and topped with cheese.  This spaghetti casserole is baked in the oven until hot and bubbly.

Just like stuffed shells, this easy recipe is perfect served with  crusty bread, homemade Garlic Butter and a Caesar Salad.

Easy Baked Spaghetti

This easy baked spaghetti casserole is a family favorite that is loaded with flavor!  We love Italian flavors from Easy Meatballs to a simple bruschetta and this cheesy casserole is no exception!

While Million Dollar Spaghetti Casserole contains a lot of cheese in the spaghetti mixture (like cream cheese, cottage cheese or ricotta), this recipe is simple has pasta and sauce with a little bit of cheese on top.

How to Make Baked Spaghetti

Baked Spaghetti Casserole is easy to make, simply prepare the meat sauce, toss with spaghetti and bake until bubbly. The prep can be done then night before and then baked before serving making this baked spaghetti the perfect potluck dish!

  1. Brown beef and onions. Add veggies and tomato sauce and simmer.
  2. Stir in spaghetti and place in a dish.
  3. Top with cheese and bake!

The cheese on top gets golden and crusty making for amazing flavor! Make sure your spaghetti is cooked al dente as the noodles do cook a bit more in the oven and you don’t want them to get mushy.

One great thing about this recipe is that you can add whatever you like to the sauce. If you don’t like green pepper, skip it and add diced mushrooms or zucchini.  You can easily adjust this to your liking and add more or less sauce if you’d prefer.

How Long to Bake Spaghetti

Since the pasta and the sauce are warm when I put this dish together, it usually takes about 25 minutes or so to bake in the oven.  If you prep it ahead of time and refrigerate, it’ll take a bit longer.  Remove it from the fridge about 30 minutes before baking and bake about 35 minutes or until hot in the centre.

Do You Cover Baked Spaghetti

I never cover baked spaghetti because the  crusty cheese on top is my favorite part!  Covering this dish also makes it steam which can overcook the spaghetti.

  1. It’s nice to have a little change now and then and this was worth trying for sure! I will definitely make this again when our kids come over.5 stars

  2. I left out the garlic, onion and green pepper (dietary issues) and substituted 1 small bunch green onions. Also, I used oregano, marjoram, thyme and sprinkling of cinnamon for the “Italian Seasoning”. Lastly, I used mozzarella and for a kick used a blend of parmesan, romano & asiago.

    It turned out fabulously! I used some angel hair pasta however, I need to use gluten-free next time, again due to dietary issues.

    Thank you for sharing this recipe!5 stars

    1. You may want to try crushing the tomatoes, the chunks remain in tact in the end. Good luck ;)
