Packed with seasoned ground beef, melted cheese, sour cream, and fresh toppings, this Low-Carb Mexican Taco Casserole delivers all the flavor of a classic taco bake without any flour or tortillas.
While clickbait social media captions often claim recipes like this are “zero carbs,” ingredients like tomatoes, onions, olives, and dairy naturally contain small amounts of carbohydrates—making this an ultra-low-carb, keto-friendly option rather than strictly zero-carb.

Step-by-Step Instructions
Step 1: Cook the Meat Base
1. Preheat oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Heat a large skillet over medium-high heat. Add ground beef and diced onions; cook for 6 to 8 minutes until the meat is fully browned. Drain any excess fat.
3. Stir in taco seasoning, water, and green chilies. Simmer for 3 to 5 minutes until the sauce thickens, then transfer the meat into the prepared baking dish.
Step 2: Layer the Cream Cheese & Cheese
1. In a small bowl, stir together the softened cream cheese and sour cream until smooth.
2. Spread the cream cheese mixture evenly over the warm taco meat layer.
3. Top generously with the 2 cups of shredded Mexican blend cheese.
Step 3: Bake & Top
1. Bake uncovered for 15 to 20 minutes, or until the cheese is melted and bubbling at the edges.
2. Remove from the oven and allow to cool for 5 minutes.
3. Layer the fresh toppings—diced tomatoes, sliced black olives, jalapeño rings, diced avocado, and fresh cilantro—evenly over the melted cheese before serving.
Chef’s Tips
Extra Base Layer: For a sturdier base without carbs, fold cauliflower rice or riced zucchini into the seasoned meat before baking.
Make Ahead: Assemble the meat and cheese layers ahead of time, cover, and store in the fridge. Bake directly when ready and add fresh toppings right before serving.
