The Best Keto Taco Casserole
Taco night is a big deal in my household. We all have our favorite taco recipe, and one of my favorite things to do is set up a bar for everyone to assemble their own tacos.
But what's even easier, and a recipe we all love is this keto taco recipe. It's made using the best taco ingredients, and because it's a casserole, I can prepare it at the start of the week for us to enjoy all week long!
I guarantee your family is going to love this keto taco pie. It is low-carb, gluten-free, and so delicious. Perfect for making ahead of time as part of your meal prep plans or for a party like a potluck or game day.
Another one of my family's favorite ground beef meatballs is my Instant Pot Meatballs. They are the juiciest meatballs you will ever make!
Homemade Taco Seasoning
- chili powder
- garlic powder
- onion powder
- red pepper flakes
- dried oregano
- paprika
- ground cumin
One of my secrets to making the best low-carb taco casserole is to use homemade taco seasoning. Something that always frustrates me about different taco seasoning mixes is that there's always a little something I'd like to adjust about them.
Making homemade taco seasoning is the easiest way to get all the flavors you love into one simple blend. It's simple to do and so worth it! You can use store-bought taco seasoning, but if you have the necessary spices on hand I recommend making it yourself.

Keto Mexican Casserole Toppings
- Avocado
- Tomatoes
- Jalapenos
- Extra cheese
Our favorite toppings for our keto Mexican taco casserole are exactly what you'd use for tacos in shells. I personally love avocado and tomato slices for freshness, and always enjoy jalapenos for a little extra spice.
Pico de gallo or simply cilantro would also be great additions to our low carb taco casserole recipe. If you're not worried about keeping it strictly keto, you can also add fresh corn and black beans.

FAQs
This recipe is enough for 6 servings. Each serving has about 8 carbs.
Yes! Sour cream has a lot of fat content with low carb content, so it's perfect for a keto diet. We use sour cream as part of our keto taco casserole filling.
Shredded cheddar is our cheese of choice for this recipe. You can also use a shredded Mexican cheese blend, Colby Jack, or your favorite shredded cheese that melts well.
Add a little spice by giving it a dash of hot sauce or by adding jalapenos.
Avoid adding jalapenos and use less or no red pepper flakes in the seasoning.

Keto taco casserole is delicious. I was staring at the ground beef in the refrigerator wondering what to do with it as usual, then saw this recipe yesterday morning on Pinterest. I added salsa to the ground beef after browning it instead of the taco seasoning, tomatoes & chilies. Mixing eggs with sour cream & milk was new to me and it was all so easy. I didn't add oil to the baking pan as I have a non stick one. 25 minutes was plenty of time. This came out beautiful and we loved it. Served a salad and string beans along with it. Thank you! Yay Keto! Inspired to find new Keto recipes.
