Ingredients In Keto Squash Casserole

So what do you need to make this yummy yellow squash casserole low carb? You probably have all of these ingredients handy (and have used them recently and frequently!) if you’ve been eating keto for any length of time:

  • Yellow squash
  • Green onion
  • Egg
  • Heavy whipping cream
  • Cheddar cheese
  • Butter
  • Pork rind
  • Parmesan cheese
  • Salt and pepper

See? Not even 10 ingredients!

Is Yellow Squash Low Carb?

When I first went low carb, I didn’t realize I could enjoy zucchini and squash. I thought I was stuck with kale and lettuce and broccoli.

So, is squash a carb? Your quick answer is NO!

Your average cup of squash has only about 3 net carbs per serving. With so few carbs in squash, you have so many options: spaghetti squash, zucchini, summer squash, yellow Italian squash…how exciting! (source)

You can even use a squash mixture if you have all of the above handy for a new take on an old classic, comfort food, southern style casserole. Squash medley casserole follows the same recipe, just using a variety for the vegetables.

How To Make Simple Squash Casserole: Easy Peasy!

This is a really easy recipe to make (and easy is my favorite kind!). The first step is chopping your yellow squash up. Next, cook it in a skillet with some water.

Next you’ll add green onions to the skillet. Sauté them and season them with salt and pepper.

Place the vegetables in a casserole dish, a 9×9 square (if you double the recipe, you can just use a 13×9).

Combine a beaten egg and heavy whipping cream and pour over the squash. (Some recipes use sour cream instead, but this works really well with the other flavors).

To make the crumbly topping, mix together parmesan cheese and crushed pork rinds and then add melted butter to it.

Spread the shredded cheese on top of your chopped squash.

Top the cheese with the pork rind parmesan crumbles.

Bake them for 20 minutes until the cheese is bubbly and the casserole is hot and flavorful.

Low Carb/Keto Yellow Squash Casserole Tips

Isn’t it easy? If you’ve never had yellow squash casserole, you’re in for a huge treat. And if you’ve been eating low carb and afraid you were going to have to miss out on this southern favorite, you’ll be pleased to know it’s not true.

This keto squash casserole has all of the flavor and even texture of the carbohydrate laden classic. Here are a few tips to make it even easier to make.

Make Your Keto Squash Casserole Ahead Of Time

Go ahead an assemble it all, cover it well, and put in your fridge or freezer. Simply remove it straight to the oven and start baking. You’ll have to add 5-10 minutes if it’s been in the fridge and 15-20 from the freezer (just watch it and test the middle).

Reheating Leftover Squash Casserole

To reheat in the microwave, simple add a few drops of water to the bottom of your dish and cover loosely.

You can also heat it in a toaster over or traditional oven.

Making Yellow Squash Casserole A Main Dish

Want to enjoy your keto squash casserole as your main dish? Just add some protein!

You can add in cooked ground beef or diced smoked sausage. Adding Italian sausage or even crumbled breakfast sausage also adds a delicious flair to this dinner.

A more subtle flavor would be to add shredded chicken. I find doing this and adding in some baby spinach is quite yummy. Add some chopped jalapeños for some heat.

Another delicious option is making your keto squash casserole with bacon. Add some bacon crumbled over the top -and, if you’ve got plenty, add it into the casserole too. This makes an excellent side to a quiche, but it can easy stand alone for a simple keto lunch.

You can also turn it into a Greek squash casserole by swapping the parmesan for feta and adding baby spinach and chopped kalamata olives right before baking. When it comes out, top with diced tomatoes.

What If I Don’t Have Yellow Squash?

This keto squash casserole recipe can also be made with zucchini or any squash you have (even spaghetti or acorn!). Make it up and enjoy! If you use a much firmer squash, just cook it in the skillet until tender.
