This easy keto taco casserole sneaks in healthy squash along with ground beef, melted cheese, and delicious taco flavor! Plus it only takes about 10 minutes to prepare and is ready in 5 simple steps.
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. My kids love spaghetti squash lasagna too!
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 keto squash casserole recipe comes together in five easy steps? It’s truly so easy!
Preparing the ingredients
- 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.
- Brown the ground beef in a skillet and drain any excess grease.
- Add the canned tomato and seasonings to the ground beef and simmer for about 5 minutes.
Assembling and baking the casserole
- Place the sliced squash in the bottom of a 9x13 inch baking pan. Layer the ground beef over the squash, then sprinkle the cheese on top.
- 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.
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!

Thanks for sharing. Can't wait to try.
Looks very goid
I was wondering how it would change the carb content if I make this using the base from your low carb pizza casserole for this instead of the summer squash. Any idea? I guess I can enter all the ingredients in an app counter. I am not a squash fan. ????
You can definitely sub out the squash with low-carb pizza crust or tortillas. There's a free recipe analyzer on MyFitnessPal you could try. Most keto diet apps also have a calculator.
I made this tonight with my abundance of garden summer squash. I’m not following keto, so I added some tortilla strips on top for some crunch. I had 2 helpings. I thought it was just spicy enough ( I used tomatoes with green chili’s), but a little saltier than I like to cook. That might have been due to the fact that I salted the squash to reduce the moisture before cooking, rather than grill them. It was a good addition to my garden squash recipes. If you have kids who don’t care for spicy, just leave out the cayenne and/or reduce the chili powder and cumin. But I think kids would like this casserole, especially if you add some tortilla chips on their portions.
My family and I absolutely loved the casserole! It was my 1st time making a low carb casserole. All the spices blended well with the squash. We topped it w/salsa and sour cream. It was absolutely wonderful!
Ms Lisa I preorder your cookbook, I haven't gotten it yet. And I'm so excited and can't wait to get it! Thank you for sharing your love of cooking????
I'm so happy the casserole was a hit. Thanks so much for preordering the cookbook! I hope you enjoy the book recipes too.
Your recipe was so delicious and fit perfectly into my meal prep!
Looks yummy, but approximately how many squash equal 2 cups? Or, how many ounces or grams? I need some clarity for my macros.
It's about 2 medium yellow squash.
I tried this last night without cayenne pepper and added sour cream, black olives, and green onions, also sprinkled a little cheddar on top after it was done, and oh, my my my, even my hubby LOVED it. Thank you so much for sharing this recipe! 🙂
Sorry for stupid question from new cook but is summer squash yellow zucchini or is there something that is actually called summer squash
I've never heard it called yellow zucchini, but it is a squash similar to zucchini but yellow in color.
