Best Spaghetti Casserole Recipe - Simply Stacie (1)

Growing up, we ate a lot of baked pasta casseroles. My mom was a big fan of them and this recipe for Spaghetti Casserole was one of her favorites.

Being the picky kid that I was, I hated it. That was normal for me since I disliked pretty much all foods except for a few things. Now that I’m an adult, I can see the appeal.

This casserole is delicious comfort food and is worth the bit of extra assembly required to make it.

It requires a few extra steps to prepare it. You have to cook the spaghetti noodles first as well as brown the ground beef. The veggies are chopped and cooked separately. That creamy sauce comes from a can – it’s cream of mushroom soup! I’m not a big fan of canned cream of mushroom soup, but I like it in this recipe.

It’s messy to eat but so good. It’s also huge so it serves a good amount of people. If your family is small, you’ll probably have some leftovers. It tastes just as good heated up the next day.

Once the pasta is in the sauce, add pasta water. This is the most vital step in the process. Starchy pasta water doesn't just help thin the sauce to the right consistency; it also helps it cling to the pasta better and emulsify with the fat and cheese you're going to be adding.
