Keto Taco Casserole

  • Author: Stephanie Parlegreco

  • Yield: 12 servings 1x


We have the BEST Keto Taco Casserole right here! It’s loaded with ground beef, and topped with cheesy goodness. It has everything you love about a taco without all the carbs. Your entire family will love it!


  • 2 lbs ground beef  
  • 4 tbsp homemade taco seasoning 
  • ½ cup chopped onion 
  • ½ cup chopped bell pepper 
  • 1 can Rotel tomatoes with green chiles 
  • 6 eggs 
  • ¼ cup heavy cream 
  • ⅓ cup sour cream 
  • 2 cups shredded cheddar cheese





I like to use 85% or 80% lean ground beef

If there is liquid after cooking the ground beef, you may want to drain it. 

A meat chopper is a great tool for breaking up and mixing ground meat. If you don’t have one I’d suggest getting one

9×13 casserole dish is perfect for this recipe. Glass or ceramic will work. 

Topping Suggestions: sour cream, olives, salsa, cilantro, tomatoes, jalapenos.

Egg-Free Option: If you have an egg allergy you can leave out the eggs and the egg mixture entirely. Instead, mix in 8 oz of cream cheese with the meat mixture while still in the frying pan. Transfer to baking dish, then top with cheddar cheese and bake. 

TO REHEAT IN THE MICROWAVE: Place in a microwaveable dish for 60-90 seconds or until desired heat has been reached. 

TO REHEAT IN THE OVEN: Bake in the oven for 10-15 minutes at 300 degrees. 

FREEZE BAKED LEFTOVERS OPTION 1: If you have leftover keto Mexican casserole, place it in an airtight container and place it in the freezer for up to 3 months. 

FREEZE BAKED LEFTOVERS OPTION 2: Bake the low carb taco casserole, let it completely cool. Cover with plastic wrap and foil. Place in the freezer for up to 3 months.

THAWING INSTRUCTIONS: Let your keto taco casserole thaw in the fridge, before baking it. If you place an ice-cold glass or ceramic baking dish straight from the freezer to the oven it may crack when reaching the hot temperature. Remove the plastic wrap and foil. Bake for 15-20 minutes at 350 degrees.
