Onions, Ground Beef and Spaghetti Squash

In my cupboard I have two very special cookbooks filled with family recipes. And, they are filled with family photos too. So, every time I open one of them, I get to take a walk down memory lane. The first volume was put together by my grandma and the second by my mom. Spaghetti squash casserole is a variation of my aunt’s recipe found in volume one of the family cookbook. My aunt would make it when we visited, and my mom made it a lot when we were growing up. The original recipe calls for cooked spaghetti noodles, which I’ve switched out for baked spaghetti squash. Baked Spaghetti Squash is super easy and delicious.

Browning Ground Beef

Make a Meat Sauce

Spaghetti squash casserole is all about layers, kind of like lasagna. First, start by making meat sauce. In a pan, sauté chopped onions in olive oil until they soften. Then, add ground beef to the pan. Break up the ground beef and brown it up. Stir the ground beef occasionally as it cooks, mixing it in with the sautéed onions. Once the ground beef crumbles are all cooked, season the mixture with garlic powder and dried Italian seasoning.

Here’s a quick video showing you how to finely chop an onion. This is the method I use for chopping all my onions.

Ground Beef Meat Sauce

To speed up the prep time on this recipe, add a jar of your favorite pasta sauce and a can of tomato paste to the pan. You can also make homemade pasta sauce too. Spaghetti squash casserole taste great both ways, so it’s all up to you. Let the meat sauce simmer on low for at least 20 minutes.

Cream Cheese, Cottage Cheese, Sour Cream and Seasoning

Prepare the Creamy Cheese Layer

The next layer of the casserole is filled with cheesy creamy goodness. In a bowl, combine softened cream cheese, cottage cheese, sour cream, onion powder, garlic powder, and dried Italian seasoning. Stir everything together until it’s evenly mixed and smooth. You can also use ricotta cheese instead of cottage cheese, whichever you have in your refrigerator.

Layering Spaghetti Squash Casserole

Layer the Casserole

Now that your creamy cheese mixture is ready, it’s time to start layering the casserole. Start by spraying a 9″ x 13″ dish with non-stick spray. Add half of the cooked spaghetti squash to the pan. Smooth it out into an even layer. Then, add half of the cream cheese mixture. Smooth this out on top of the squash. Repeat this process with the remaining squash and cheese mixture so that you have two layers of each.

As soon as the meat sauce is done simmering, carefully layer it on top of the second cheese layer. Finally, top the casserole with shredded mozzarella and parmesan cheese. At this point, you can immediately bake the casserole at 350° for 30 minutes until bubbly around the edges. If you’re preparing the casserole in the morning to serve later in the day, cover it and keep it in the refrigerator. Let the casserole come to room temperature before baking, or add about 10 minutes to the baking time if baking straight from the refrigerator. Lastly, you can freeze the spaghetti squash casserole. It freezes great. Bake from frozen for 55-65 minutes.
