Cheesy Baked Spaghetti Casserole Recipe Makes Everyone Happy

Here’s a casserole recipe that can be put together ahead of time, and can be as complicated as you want, depending on whether you make your own sauce or just use a jarred sauce. And it is vegetarian, thanks to the meatless meatballs.

I’m not a vegetarian, though we eat many meatless meals. But my vegan daughter introduced me to the Gardein plant-based meatballs that I prefer over “real” meatballs because they are much less greasy and they just taste great! Note that this recipe as originally written was intended to be cooked in a deep-dish pie pan, but I opted for an 8x8-inch baking pan instead.

Cuisine: Italian
Prep Time: 20 minutes
Cook Time: 30 minutes
Total Time: 50 minutes

Servings: 4 


Here’s how to make it:

  1. In a large skillet, add the spaghetti seasoning to the sauce. Heat the sauce until simmering. Add meatballs. Simmer for 10 minutes. Cut the meatballs into small pieces. Reserve some sauce in case your casserole is a little dry, especially when reheating.
  2. To your pan with cooked and drained spaghetti noodles, add 1/4 cup Parmesan cheese, 1/4 cup mozzarella cheese and stir.
  3. In a medium bowl, mix sour cream, eggs, 1/2 cup mozzarella cheese, 1/2 cup Parmesan cheese and Italian seasoning.
  4. Layer the cooked spaghetti in the bottom of a lightly greased 8x8-inch baking pan. Spread sour cream mixture on top with spatula. Cover with meatball sauce mixture.
  5. Bake uncovered in a preheated 350-degree F oven for 20 minutes. Add 1 cup mozzarella cheese and bake an additional 10 minutes.

Note: If you have a favorite homemade spaghetti sauce, by all means substitute that for the jarred sauce and spaghetti seasoning. And use your favorite meatballs.
