Low Carb Taco Casserole Recipe

Lately I’ve been in a meal planning rut. During the week, I try to plan ahead at least two or three meals in advance so when dinner time comes on those busy weeknights we’re not scrambling to get a meal on the table.

My favorite quick and easy delicious recipes are these skillet pork chops or this jalapeno popper chicken. If you haven’t tried those, get them on your menu asap! They’re always a hit and super delicious when warmed up the next day for lunch.

This Keto Taco Casserole was inspired by my vegetarian enchilada casserole. I guess I wasn’t quite ready to put Mexican food on the back burner. Although my enchilada dish is low carb with low carb corn tortillas, I was craving the ultimate keto taco casserole dish.

Ingredients you will need:

This easy keto taco casserole recipe only requires a handful of ingredients and most you probably have stocked.

  • Lean ground beef or ground turkey. Both options are delicious. I happen to have turkey more often that that I get from Costco. Ground turkey from Costco comes packaged in 1-1/2 pounds, which is the perfect amount for this recipe. However, using full-fat beef is completely acceptable when following a low carb diet.
  • Homemade taco seasoning – make your own and keep it stocked in your spice drawer. You will need 3-4 tablespoons, so if you buy the packets you’ll need 2.
  • Rotel tomatoes – pick mild, medium or hot. I use the original style. You’ll use 1/2 cup of this, so the remaining can you can mix in this cheese nacho sauce. Alternatively, you can add diced tomatoes and add 2-4 ounces of chopped green chiles.
  • Cheese – cream cheese and shredded cheese. I used a Mexican blend, but you can mix in your favorite flavors or just have one flavor like cheddar cheese, pepper jack or monterey jack cheese .
  • Sour cream – full fat for rich great tasting casserole.
  • Vegetables – diced fresh tomatoes, sliced black olives and green onion.

How to make keto taco casserole

Turn taco night in to a delicious keto style meal and finish with your favorite taco toppings.


Place the ground beef or turkey in a large skillet over medium-high heat along with the taco seasoning. If you are using a low fat protein, then you will want to add a tablespoon of avocado or olive oil to the skillet. On the other hand, if the meat if filled with excess fat or water, you may want to drain before mixing in the taco seasoning.


Next, add the diced Rotel tomatoes and cream cheese into the ground beef mixture. You can really ramp up the flavor to suit your taste buds depending on the tomatoes you use. There are so many options! I used the original version.


Mix until the cheese melts and the tomatoes are well disbursed through the taco meat.  


Place the cooked meat in a casserole dish. Top with sour cream, fresh diced tomatoes, olives and green onions.


Top the casserole with shredded cheese before placing in the oven. Bake at 350°F for 30 minutes or until cheese is melted.
