This satisfying Keto Chicken Enchilada Casserole brings all the comforting Tex-Mex flavors you crave without the carbs. The creamy, cheesy goodness wrapped around tender shredded chicken creates that authentic enchilada experience while keeping your low-carb lifestyle intact.
I first created this recipe when my family transitioned to a lower carb lifestyle but couldn't bear giving up our weekly Mexican food night. After several attempts perfecting the sauce to cheese ratio, this casserole has become our most requested dinner even by non keto friends.
Ingredients
- Shredded chicken: I recommend rotisserie for convenience and rich flavor
- Cream cheese: creates that creamy texture you crave in traditional enchiladas
- Cheddar cheese: sharp varieties add the perfect tangy depth to balance the richness
- Mozzarella cheese: provides that Instagram worthy cheese pull when serving
- Red enchilada sauce: look for low sugar versions for authentic flavor without carbs
- Green chilies: adds subtle heat and authentic Southwestern character
- Fresh garnishes: lime, cilantro, and avocado brighten the rich casserole
Step-by-Step Instructions
- Prepare The Cheese:
- Grate and combine both cheeses in a bowl. Freshly grated cheese melts significantly better than pre-shredded varieties which often contain potato starch. Reserve half for the topping and use half in the filling mixture.
- Create The Filling:
- Thoroughly mix one cup of enchilada sauce with the cream cheese until completely smooth. Fold in half of your cheese mixture and all of the shredded chicken. This creamy base is essential for capturing that authentic enchilada creaminess without tortillas.
- Assemble The Casserole:
- Spread the chicken mixture evenly across your baking dish, pressing gently to create a solid base. This ensures even cooking and proper serving portions later. Top with remaining cheese ensuring complete coverage.
- Final Layer And Bake:
- Pour remaining enchilada sauce over the cheese layer allowing it to seep slightly into the cracks. Sprinkle with fresh diced green chilies. Bake at 390°F for 15-20 minutes until the edges are bubbling and cheese has developed light golden spots.

The secret to this casserole's incredible flavor is allowing the cream cheese to fully incorporate with the enchilada sauce. The first time I served this at a neighborhood potluck, three people asked for the recipe before dinner was over, completely unaware it was keto friendly.
Make Ahead Options
This casserole actually improves with time as the flavors meld together. You can assemble the entire dish up to 24 hours before baking. Simply cover tightly with plastic wrap and refrigerate. When ready to bake, allow the casserole to sit at room temperature for 30 minutes before placing in the oven. You may need to add 5-7 minutes to the baking time if starting from cold.
Customization Ideas
While this recipe is perfect as written, I love how adaptable it is to different tastes and dietary needs. For a spicier version, add diced jalapeños or a teaspoon of chipotle powder to the chicken mixture. To increase the vegetable content, fold in sautéed bell peppers, zucchini, or spinach. For those who miss the texture of traditional enchiladas, consider adding thin slices of jicama as a tortilla substitute layered throughout the casserole.
Serving Suggestions
This versatile dish can be served multiple ways depending on your preferences. For a complete meal, pair with a simple side salad dressed with olive oil and lime juice. For family style serving, set out bowls of optional toppings like sour cream, extra cheese, sliced jalapeños, and diced avocado so everyone can customize their portion. If you have non keto family members, consider serving with a side of black beans or Spanish rice for them.
