FAQs & Tips
What is spaghetti squash?
Spaghetti squash is a cucurbita pepo vegetable. In other words, it’s a squash. The seeds inside spaghetti squash are similar to pumpkin seeds. When cooked, the inside flesh is scraped into spaghetti-like strands. Hence why spaghetti squash exploded on the scene a few years ago as a popular, healthy, alternative to spaghetti. You can cook spaghetti squash several ways, including in the slow cooker; either by itself or as a part of a recipe like you see here.
What pizza topping should you use?
What I love most about this recipe is that when it comes to the toppings, the sky is the limit! I wanted a meaty pizza so I used a combination of pre-cooked sausage & pepperoni. Make it a vegetarian pizza by using chopped vegetables like olives, bell peppers, onions, etc. Whatever you like on your pizza, you can use here as your topping for this pizza casserole.
What can you substitute for the pizza seasoning or Italian seasoning?
I suggest another dried herb like oregano or basil.
How do you store leftovers?
Store leftover spaghetti squash pizza in the refrigerator for up to 4 days.
What size slow cooker did you use?
I used a large 6-quart slow cooker.

This was surprisingly good. We have been trying various recipes to use our bounty of spaghetti squash from the garden and this one is the best we’ve found hands down! We added green peppers, onion, a couple mushrooms and a bit of sausage for toppings. Thank you for this delightful, healthy meal!
CAn you make it in the instantpot?
If I wanted to cook in the oven instead of in my crock pot how long would I cook it for?
Bake at 375 for 20 min or until cheese melted. Here’s an oven version for reference – https://fitslowcookerqueen.com/low-carb-spaghetti-squash-pizza-casserole/
We tried this just now and it’s so incredible!! Thanks SO MUCH for sharing this recipe, and I think we have a new family favourite! <3
This was absolutely delicious!! i made some minor modifications… I placed separate servings of the squash spaghetti in a muffin baking pan and baked for about 15 min to dry out some of the moisture. Then, I added the sauce, cheese, and turkey pepperoni and continued to baked until cheese melted. Finally, I broiled for about 2 minutes to get the golden brown tone on the cheese. This made up our healthy lunch servings for the week.
Genius! I love that you made them into muffins. I never thought to bake them to dry out some of the moisture. Thank you so much for sharing. I’m so glad to hear you enjoyed the recipe!
