Squash Casserole

I love low-carb recipes that use fresh, seasonal ingredients. Zucchini and squash are some of my favorites. They are colorful and have so many nutrients. Plus, the cream cheese adds a layer of creamy goodness.

You won’t be able to wait to sink your teeth into it.

When I started eating low-carb, I knew that I wanted to create recipes that my family can eat with me. It isn’t fun to eat different foods that everyone else all the time. That’s why I created something full of fiber and vitamins that will keep me in ketosis and be good for my kids too.

What’s In this Low Carb Cheesy Squash Casserole

There are only a few really easy-to-remember ingredients in this recipe. You might already have most of them in your refrigerator.

  • Squash
    Cream Cheese
    Shredded cheddar cheese
    Pork rinds
    Sliced mushrooms
    Sour cream
    Garlic powder

The Crunchy Low Carb Topping

Bread crumbs are obviously not low carb, so for this recipe, I used ground pork rinds for the crunchy topping. They add the perfect amount of crunch to the casserole without any additional carbs. Plus, this makes the recipe gluten-free too. You can ground them yourself by crushing them in a plastic storage bag or you can use these Pork Rind Breadcrumbs.

How to Avoid Cutting Up An Onion

I don’t blame you, I don’t like chopping up onions either. I’ve heard that using a really sharp knife will lessen the number of tears you get but that’s just not enough for me.

If you really want to avoid chopping up an onion, just use an onion chopper or buy frozen diced onions at the store. Saves you lots of time – and tears. Win-win!

Can you use diced garlic?

I prefer to just use garlic powder in this recipe. But if you want, you can use diced garlic too. You can use the same amount for the same taste.

How Long Will Low Carb Squash Mushroom Casserole Last?

Honestly, zucchini and squash recipes that I make with cream cheese don’t reheat very well. I’d only keep this in the refrigerator for about a week, max. Try to eat it all up at dinner though, it just tastes a lot better when you eat it fresh.

How to Freeze It

Before you bake it, put the casserole dish in the freezer, sealed tight with a lid. Then, when you are ready to bake the casserole, take it out the night before and let it thaw in the refrigerator. Bake it the next day.
