Casserole dishes are a favorite in our household. They’re easy to make and always so satisfying.

I was in the mood for a taco casserole, but I didn’t want to use tortillas. It’s hard to find gluten-free ones at the store, and I didn’t have time to make a batch of my coconut flour tortillas or almond flour tortillas.

A lot of people use zucchini in place of noodles in casseroles. So, I thought why not use yellow squash in place of tortillas for a keto taco casserole. Sounds reasonable, right?

Turns out, it was a great idea! This low carb yellow squash casserole is a winner. I’m putting it down as a regular on my low carb menu.

This tasty dish only takes about 10 minutes to prep and another 25 to bake. So you can be sitting down to a tasty dinner in under 40 minutes!

And with the tasty melted cheese, ground beef, and taco seasoning, even your kids will scarf it down. It’s a great way to sneak some veggies into a hearty meal.

The next time you’re in the mood for a low carb taco casserole that doesn’t require tortillas, give this easy keto taco bake a try!

How to make the casserole

Would you believe me if I told you that this recipe comes together in five easy steps? It’s truly so easy!

Preparing the ingredients

1. Thinly slice the summer squash, then pan-grill to remove excess moisture. The pan-grilling step is optional, but it helps prevent a soggy casserole.
2. Brown the ground beef in a skillet and drain any excess grease.
3. Add the canned tomato and seasonings to the ground beef and simmer for about 5 minutes.

Assembling and baking the casserole

1. Place the sliced squash in the bottom of a 9×13 inch baking pan. Layer the ground beef over the squash, then sprinkle the cheese on top.
2. Bake at 350°F for about 25 minutes.

That’s it! This taco casserole is so easy to make, it’s perfect for whipping up on a busy weeknight. 

If you have any leftovers, you can store covered in the refrigerator for up to 5 days.

Best way to prep the summer squash

I mentioned that pan grilling your summer squash to remove excess moisture is optional. Every squash is going to have slightly different water content, so it’s really a judgement call.

The other option is to lightly salt both sides of the summer squash slices and let them sit for about 30 minutes. This will draw out the water. 

Once you see droplets, you can simply wipe them away with a towel.

You have the option to entirely skip these steps. However, if your casserole turns out a bit soggy, the moisture in your squash is probably to blame.

Variations

To keep this taco casserole keto, I wanted to use summer squash in place of tortillas. 

This was mostly because I had a large crop of summer squash from my garden that I needed to use. If you can’t find summer squash, zucchini will work just as well! You’ll cook it the exact same way.

The same thing goes for the cheese. I used cheddar simply because I usually have some in the refrigerator. A Mexican cheese blend or even pepperjack would work very well for this recipe.

For an extra kick, try adding 2 or 3 freshly chopped green chilis to the ground beef and tomato mixture. If you want something a bit milder, a can of diced green chilis could be used as well.

You can also dress up this casserole however you like. After the bake, feel free to add toppings like sour cream, black olives, green onions, avocado, or even more cheese!
