Keto Cheesy Chili Spaghetti Squash Casserole

Raise your hand if you love cheese! Just kidding, put it down….you know I can’t really see you right???

Don’t worry though, I know how you feel. I felt your fervent love of cheese from all the way over here. Because who doesn’t love cheese? Even people who can’t eat cheese WISH they could.

What’s not to like, really? Cheese makes everything better, and that’s a fact.



Recipes containing cheese practically write themselves because I can literally start with cheese, open my fridge and grab 5 other random things to add to that cheese and BAM! Delicious.

I put a little more effort into it than that for this Keto Cheesy Chili Spaghetti Squash recipe, but not much (shhh, don’t tell anyone.)

My one caution about buying pre-shredded cheese is that you should be aware that all shredded cheese has added starch to coat the shreds and keep them from sticking together in the package. That can add a gram or two of carbs per serving, so if you are on a very low carb diet (20g or less) you may want to opt for the block and shred it yourself at home.

Another option is sliced cheese – I sometimes just layer the slices in a keto casserole recipe like this one, or the Easy Cheesy Cauliflower Gratin, which uses slices of pepper jack cheese.  Loaded with flavor and super easy to throw together, you definitely need to check that keto cauliflower recipe out if you haven’t already!



This cheesy keto casserole recipe has a spaghetti squash base, then a layer of cheese, a layer of sour cream, a layer of chili, and then more cheese (of course.)  It’s hearty and satisfying, but not so heavy that it will weigh you down.

I like mine sprinkled with cilantro, but that’s completely optional.  You can also serve this keto cheesy chili spaghetti squash casserole alongside some salsa, additional sour cream, and guacamole or slices of avocado (sadly, mine weren’t ripe yet so they didn’t make the photos.)



Whether you eat this tasty keto spaghetti squash casserole as is, or garnish it with your favorite chili toppings, this one is going to be a hit with the whole family!
