Is Squash Good For Keto?

The answer to this question depends on what kind of squash we’re talking about.

Varieties of summer squash, like zucchini or yellow squash, are pretty low in carbs. They usually contain around 4 grams of carbohydrates and 1 gram of fiber per cup. Summer squash have a long shape and soft, edible skin.

Winter squash, on the other hand, have more variety in both shape and nutrient profiles. For example, butternut squash has 21.5 grams of carbs and 6.6 grams of fiber per cup while acorn squash has 15 grams of carbs and 2.1 grams of fiber per cup.

Spaghetti squash is one of the lowest-carb winter squashes with 7 grams of carbs and 1.5 grams of fiber per cup. That’s why you may see it used in Keto-friendly pasta dishes in place of traditional, high-carb noodles.

So long story short, you’re usually pretty safe with summer squash, like the yellow squash used in this recipe. You can still enjoy winter squash in moderation, just be sure to watch your serving size.

Can You Use Something Instead Of Pork Rinds For The Toppings?

You bet!

I know not everyone likes pork rinds. In that case, just use these homemade bread crumbs instead. You only need 4 ingredients to make them, and they add an amazing crunch!

The breadcrumbs will also turn your Keto squash casserole into a vegetarian-friendly dish. So if you’re cooking for a crowd, this recipe is a great low-carb, gluten-free, meat-free option to please a wide variety of eating preferences.

On a side note: if it’s the smell of pork rinds that you don’t like, I have a suggestion for you. 

Simply crush them into a crumb consistency, then place them in a bowl in the freezer for about 15 minutes. It works wonders for getting rid of the smell!

Can You Store Keto Squash Casserole?

Absolutely. After all, one of the best parts about making a casserole is knowing that you get to enjoy the leftovers later in the week!

Simply store the casserole in an airtight container in the refrigerator. When properly stored, it will last for up to 5 days.

To reheat your casserole, I recommend sticking it back in the oven. This will both warm it up and crisp up the topping for that satisfying crunch!
