I have been making this spaghetti squash casserole for going on five years now and I think it’s safe to say at this point that it is in the top 10 when it comes to the number of times that I’ve made a specific recipe.
I have hesitated to share the recipe on my blog because it’s an adaptation of another blogger’s recipe. I have come to realize that while I still give her 100% credit for creating the recipe, the changes that I have made are my own and they are too complicated/involved to try and type out every time I mention making it on my blog. I just want to have a post that I can link to that spells out my adaptations of the AMAZING PaleOMG pizza spaghetti pie.
That said, welcome to the most delicious spaghetti squash casserole of your life. I don’t even know how it’s possible but this recipe really does taste like pizza. It’s kinda crazy. There is not one single person that I have introduced to this recipe that has not loved it and gone on to start making it themselves.
It’s an excellent dish to serve if you’re hosting dinner guests and also perfect as a drop-off meal for a friend as it’s easy to transport and heats over well.
I think I first learned about PaleOMG Pizza Spaghetti Pie when I was doing my first Whole30 but these days I go all out with modifications to the original 5-ingredient recipe. I can’t help myself and the recipe is very versatile.
Even though the recipe is simple, this spaghetti squash casserole does requires multiple steps to prep in that you have to bake the spaghetti squash first and then sauté the other ingredients on the stovetop. I promise that it’s all simple stuff and worth the effort. This is one of those recipes where the leftovers almost taste better than the first time you eat it so definitely plan to make two dinners out of it!
Topping the casserole with pepperoni and cheese is optional but I’m in the camp of let’s make it as pizza as possible!! 🙂
When I made the recipe this week I was shocked that Finn gobbled it up! My carb-loving, veggie-disliking boy not only ate what was on his plate but asked for MORE! While I am not always a fan of hiding/disguising veggies (I go for a mix of both approaches), I appreciate recipes like this where the veggies are front and center. This casserole includes spaghetti squash, tomatoes, mushrooms, onions, eggs, cheese, chicken sausage and more. Awesome to get all of that into one dish!
I am sharing my spin on the original recipe below but please feel free to put your own on it! This recipe is so adaptable. I have used different types of pasta sauces (the Trader Joe’s season Autumnal Sauce is SO good in this dish!), different types of cheese and different types of veggies. Some veggies that I’ve loved including are artichoke hearts and chopped spinach. Basically, anything that you’d top a pizza with would probably work great.
The BEST EVER Spaghetti Squash Casserole
