Easy Baked Spaghetti
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!
- Brown beef and onions. Add veggies and tomato sauce and simmer.
- Stir in spaghetti and place in a dish.
- 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.
Serve this with a side salad and garlic toast for an easy meal. This easy casserole is great leftover and freezes perfectly!
