Taco night is big around here…I mean it’s Texas!  On taco night, Maddie and I almost always make a big taco salad while the Cowboy and Paige eat tacos.  Since the weather has cooled down, I’m really not big into salads at the moment so I needed to come up with something to satisfy our taco cravings on the most anticipated dinner night of the week!  Well, especially in the winter months, I love quick and easy comfort food casseroles so this fun Cheesy Keto Taco Casserole was the answer!

Delicious Tex-Mex keto dinner on the table in 30 minutes!

This taco inspired casserole is so simple to make and can be in the oven in less than 20 minutes!  First the ground meat gets browned up with onions and seasoned with some amazing Fiesta Brand Seasonings spices like chili powder, cumin and garlic powder.  Feel free to use whatever ground meat you have on hand, beef, venison, turkey or pork will work great!

Then to make the meat filling a little saucy, add your favorite salsa!  This adds so much more flavor than plain ole’ tomato sauce and also provides a bit of heat, which I love.  You can use mild, medium or hot…whatever you like to spice up your Keto Taco Casserole.  I would just steer clear of any salsa with added sugar.

Now for the cheesy filling for this yummy taco casserole…

Now to make the cheesy filling, you’re going combine pepper jack cheese, cottage cheese, some seasonings and an egg to hold everything together.  This cheesy layer my favorite part of this casserole!!  Be sure to use a cottage cheese with at least 4% milkfat or higher to keep the carbs in this keto dinner super low. If you not a fan of the heat of pepper jack, substitute Monterrey Jack cheese.   

Now everything gets simple layered into a casserole and topped with cheese and baked for 25-30 minutes…so easy and so YUMMY!

How to serve up this taco casserole

We like to serve this Keto Taco Casserole up topped with shredded lettuce, diced tomatoes and avocado and it’s a sure fire hit!  In fact, I’ve made it twice in the past two weeks and it gets rave reviews each time!  

If you are looking forward to leftovers like I do, top each serving with lettuce and tomato instead of the whole casserole.  This will save you from having hot wilted lettuce on your lunch!
