How to Make Keto Squash Casserole, Step-by-Step Photos
This keto squash casserole recipe almost makes itself! Still, here are some tips to make sure it’s as easy to make as it is to serve and eat!:
Best Ingredients To Use & Why
This is one of many great keto yellow squash casserole recipes, and we use a few special ingredients to keep carbs in squash low, even though it tastes every bit as good as the carby original.
Yellow squash – These versatile veggies (actually, fruit!) yellow squash nutrition are low in calories and high in vitamin C and folate. When picking out yellow squash, choose small, firm fruit that are free of blemishes.
If you can’t find yellow squash, you can always sub in zucchini, or even spaghetti squash for a keto spaghetti squash casserole!
Pork rinds – These are made from fried pig skins. They work beautifully in dishes like this one as a crunchy topping in place of crackers or bread crumbs.
Xanthan gum – This is a thickener that is often used in recipes where traditional flour is subbed out — it thickens sauces in a fraction of the amount! So you can use less, and save loads of carbs.
Storing Tips
I can’t imagine having any leftovers from this decadent keto squash casserole recipe, but if you do have any, store them in an airtight container in the refrigerator.
Reheat in the microwave — or the oven or toaster oven for a crispier top layer.
Can You Freeze This?
You can definitely freeze this keto squash casserole recipe, simply make sure it’s stored in an airtight container.
Thaw in the fridge and reheat like above. If you want to freeze before you bake it, assemble and wrap it in a good amount of freezer foil. When you’re ready to cook, thaw the casserole in the fridge, then bake as directed, for a mouth-watering side dish ready to go!
Recipe Variations
Looking to mix it up? Here are some great ways to customize this keto squash casserole recipe:
- Add more vegetables. Sub some of the summer squash for a myriad of squashes, like zucchini (try zucchini casserole) or butternut. Cauliflower is another subtle tasting veggie that’d be easy to sneak in for another healthy yellow squash recipes.
- Add meat. Turn this into a keto chicken casserole by adding in some cooked meat. You could also try adding some ground beef as the base for this recipe is similar to my keto cheeseburger casserole.
- Make it spicy. If you want a bit more heat, you can always add more, or throw in a bit of cayenne!
- Use different kind of cheese. Try mozzarella for lasagna vibes (or try my cabbage lasagna ), pepper jack for something with a little zest, or any meltable cheese you have on hand.
- Add sour cream. Want to try a squash casserole with sour cream? Try adding a little sour cream as this recipe is suuuper easy to customize!

Very good
So glad you enjoyed it Ann! 🙂
4 cups of pork rinds sounds like an awful lot. Is this right??
Thanks
Hi Kim! Yes it is, they break down a lottt when smashed into “crumbs” for the topping. Hope you enjoy!
Thank you! Oh my, I guess I had a “duh” moment thinking it was 4 cups after crushing! Sorry!?
I totally get it! That would be a lot hehe!
This is a really great recipe! Could you tell me how much crumbs there is when you crush the pork rinds? I’m using pork planks and have been guessing about a cup.
Hi Kathleen, yay! Happy you enjoyed it! Nice, that will make the job way easier. You’ll want about 1 cup of crushed pork rinds.
