If you love enchiladas, this Keto Sour Cream Chicken Enchilada Casserole will hit the spot. It's made with shredded chicken, bell peppers, sour cream, green chiles, and a clean enchilada sauce for a comforting meal without the heavy carbs. A few easy whole-food swaps make it just as satisfying - you won't miss the tortillas at all.
Our family loves Mexican food, so I love to develop Mexican-inspired recipes that align with our healthy eating lifestyle without compromising on flavor. Try our Keto Chicken Taco Soup, Keto Green Chile Chicken Casserole, or Keto Chicken Fajita Casserole.
Traditionally, an enchilada recipe calls for corn tortillas. There are low-carb tortillas out there that can be used on a keto diet. However, commercial tortillas often come with hidden ingredients like preservatives and chemical stabilizers, which are contrary to a clean-eating diet and lifestyle and can cause health problems in the long run.
Cauliflower is one of my favorite low-carb swaps for situations like these. It adds a dynamic texture without altering the flavors.

Ingredients
Taco Seasoning: Choose organic taco seasoning or create homemade taco seasoning from organic and unprocessed spices. For convenience, we love the Siete brand mild taco seasoning.
Red Enchilada Sauce: Always search for organic and unprocessed if you are purchasing jarred or packaged products to avoid unnecessary ingredients. We like Siete brand red enchilada sauce.
Cheddar Cheese: Organic is best. Get cheese by the block and shred it yourself to avoid hidden starches in pre-shredded cheese, which can affect carbohydrate intake.
Full Fat 5% Fage Yogurt: This full-fat yogurt mimics the consistency of cream cheese with all of the health benefits of yogurt.

Variations and Substitutions
For a vegetarian meal, simply omit the chicken. You can use tempeh or jackfruit in its place for texture.
For extra spicy keto enchiladas, add 1-2 diced and cored jalapenos with the peppers. You can also add a teaspoon of chili powder to the taco seasoning for an extra kick!
How to Make Keto Sour Cream Chicken Enchilada Casserole
Step 1: Season and roast cauliflower florets at 425°F for 20 minutes.
Step 2: Sauté onions, peppers, and garlic in ghee or avocado oil over medium-high heat until softened.
Step 3: Mix shredded chicken, half of the cheese, Fage yogurt, sour cream, green chilies, and taco seasoning. Stir to combine.
Add sautéed vegetables and stir again.
Step 4: In a large baking dish, place an even layer of roasted cauliflower florets and pour the chicken mixture over the cauliflower.
Step 5: Top with a layer of enchilada sauce followed by a layer of cheese.
Place in the oven at 375 degrees for 35 minutes or until cheese is lightly golden brown
Step 6: Remove from oven and let cool for 2-3 minutes. Serve with cilantro, chopped tomatoes, and avocados. Enjoy!
Hint: Do not overfill the casserole dish so it does not overflow when baking in the oven. If there is any leftover chicken mixture, save it in the fridge for another day or split it into two casserole dishes!
Expert Tips
Chop your veggies and shred your chicken while the cauliflower is roasting. When you have about 5 minutes left on the oven timer, heat the ghee in the skillet and begin to saute the vegetables.
Keto Sour Cream Chicken Enchilada Casserole FAQ's
Sour Cream is low in net carbs and high in fat, which makes it an acceptable ingredient in low-carb and keto diets.
Plain Greek yogurt, coconut yogurt, or cottage cheese all work well in place of sour cream in terms of consistency and the creamy flavor sour cream offers.
Sour cream provides the creamy texture and flavor in this enchilada recipe. It can be replaced with greek or coconut yogurt or cottage cheese. Without the sour cream, it will likely still work with a little extra cheese but will produce a different flavor.
