Ingredients
- 1.5-2 pounds skinless chicken breast
- 2 cups enchilada sauce (such as Frontier brand)
- 1 cup shredded Mexican cheese blend
- 1/4 cup diced onion
- 10 ounces Rotel mild diced tomatoes and green chilies

- 1/4 teaspoon cumin
- 1/2 teaspoon chili powder

- Step 2: Preheat your oven to 400°F (200°C).
- Step 3: In a frying pan over medium-high heat, add shredded chicken, diced onion, and the entire can of Rotel tomatoes with juices. Season with salt, black pepper, cumin, chili powder, and cayenne pepper if using. Cook for about 5 minutes, stirring occasionally.
- Step 4: Remove the pan from heat and stir in the enchilada sauce, reserving 1/2 cup of the sauce to use later on top.
- Step 5: In a casserole dish, start layering: spread some chicken mixture, sprinkle cheese, then place 4 tortillas over them. Repeat to create 2 layers if desired. Finish with the final layer of tortillas, pour the reserved enchilada sauce over them to keep moist, and top with remaining cheese.

For the Chicken Filling
- 1.5–2 pounds skinless chicken breast
- 1/4 cup diced onion
- 10 ounces Rotel mild diced tomatoes and green chilies (including juice)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon cumin

Other Ingredients
- 2 cups enchilada sauce (used Frontier brand)
- 1 cup shredded Mexican cheese blend
Instructions
- Prepare Tortillas and Chicken: Begin by cooking the coconut flour tortillas according to your preferred recipe or the linked instructions. Meanwhile, boil the chicken breasts until cooked through, then shred them finely.
- Preheat Oven: Set your oven to 400°F (204°C) to get it ready for baking the casserole.
- Cook Chicken Mixture: Transfer the shredded chicken to a frying pan over medium-high heat. Add the diced onion and pour in the entire can of Rotel including its juice, which helps with cooking. Season with salt, black pepper, cumin, chili powder, and cayenne pepper if desired. Cook this mixture for about 5 minutes to blend flavors and slightly reduce liquid.
- Add Enchilada Sauce: Remove the pan from heat and stir in the enchilada sauce thoroughly. Reserve about 1/2 cup of the sauce separately to use on top of the casserole layers later.
- Assemble the Casserole: In a baking dish, start layering by spreading some of the chicken mixture first, followed by a sprinkle of shredded cheese and then 4 coconut flour tortillas. Repeat this layering once more if desired. The final layer should be tortillas topped with the reserved enchilada sauce to keep them moist, and then a generous layer of shredded cheese on top.
- Bake: Place the assembled casserole in the preheated oven and bake for 20 minutes, or until the cheese is fully melted and bubbly.
- Cool and Serve: Remove from the oven and allow the casserole to cool slightly before serving, which helps it set and makes it easier to portion.

- Using Rotel with its juice adds moisture and flavor; do not drain it.
