$1000 Baked Spaghetti Pasta Casserole Recipe Is a Winner Dinner Casseroles Pasta Vegetarian Dinner Italian Recipes

Here’s a spaghetti 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. You've heard to the TikTok million dollar baked spaghetti recipe and million dollar chicken casserole, well this is my $1000 baked spaghetti recipe!

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.

For the cheesy baked spaghetti casserole recipe, you'll need spaghetti noodles, grated Parmesan cheese, grated mozzarella, sour cream, eggs, Italian seasoning, spaghetti sauce, spaghetti seasoning and meatballs. If you have a favorite homemade spaghetti sauce, by all means substitute that for the jarred sauce and spaghetti seasoning. You could easily substitute ground beef meatballs or your favorite meatballs instead.

Serve this pasta casserole with a garden salad on the side and fresh bread.
