There are only a few ingredients in this slow cooker spaghetti squash casserole recipe. This healthy, low-carb alternative to spaghetti cooks in just a couple of hours time.
Okay I’ll admit it – this is a revision of a previous recipe, my Low Carb Spaghetti Squash Pizza Casserole. I pretty much used the same recipe (with a few modifications) and cooked it in the slow cooker. I’ve said it before and I’ll say it again – most recipes can easily be converted for the slow cooker. Please note this recipe calls for a spaghetti squash that has been previously cooked.
Did you know you can cook spaghetti squash in the microwave in under 10 minutes? Pierce a whole spaghetti squash all over with a knife, place on microwave-safe dish and heat 7-10 minutes or until soft. Be careful removing the squash from the microwave because it will be hot.
You can add as little or as many topping to this as you would like. I kept this version pretty simple and didn’t add any extra vegetables or anything just spaghetti squash, diced tomatoes, Italian seasoning, cheese, pepperoni, and sausage (previously browned).
Seriously, the sky is the limit with this recipe – you can make it vegetarian or pack it full of meat.Print

Spaghetti squash releases liquid when it cooks so don’t be surprised if the finished product is a little wet. If you have a pizza seasoning you like, feel free to swap that out for the Italian seasoning.

I’ve used both a 3.5-quart and a 6-quart slow cooker when making this and they both work fine.
