Keto Chicken Enchilada Casserole – Comforting, Low-Carb, and Easy
Craving enchiladas without the carbs or the fuss? This Keto Chicken Enchilada Casserole gives you all the bold, saucy flavor of the classic dish—minus the tortillas. It’s creamy, cheesy, and loaded with seasoned chicken, yet still fits a low-carb lifestyle.
Prep is simple, the ingredients are easy to find, and everything bakes together in one pan. It’s the kind of weeknight dinner that feels special without the extra work.
Ingredients
Method
- Preheat and prep. Heat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with a little oil or cooking spray.
- Sauté aromatics. Warm the oil in a skillet over medium heat. Add the diced onion and cook until soft, 3–4 minutes. Stir in the garlic and cook 30 seconds more.
- Season the chicken. Add the shredded chicken to the skillet, along with chili powder, cumin, smoked paprika, oregano, salt, and pepper. Toss to coat and warm through, 1–2 minutes.
- Mix the creamy layer. In a bowl, combine softened cream cheese with 1/2 cup of the enchilada sauce. Stir until smooth and spreadable.
- Assemble the first layer. Spoon a thin layer of enchilada sauce into the baking dish. If using low-carb tortillas or zucchini slices, add a single layer to help structure the casserole. This step is optional.
- Add chicken and chiles. Spread half the seasoned chicken over the base. Sprinkle over half the green chiles. Drizzle on some enchilada sauce.
- Spread the creamy mixture. Dollop and gently spread half the cream cheese mixture over the chicken. It doesn’t need to be perfect—just distribute it evenly.
- Cheese it up. Add a generous handful of the shredded cheese.
- Repeat layers. If using tortillas or zucchini, add another thin layer. Top with the remaining chicken, green chiles, cream cheese mixture, and about 1 cup more enchilada sauce.
- Finish with cheese. Sprinkle the remaining shredded cheese on top. If you like it extra saucy, add a few more spoonfuls of enchilada sauce around the edges.
- Bake. Cover loosely with foil and bake for 15 minutes. Remove the foil and bake another 10–15 minutes, until the cheese is melted, bubbly, and lightly browned.
- Rest and garnish. Let the casserole rest 10 minutes so it sets. Top with chopped cilantro, and add jalapeños, avocado, or sour cream if desired. Serve with lime wedges.
Why This Recipe Works
This casserole skips traditional tortillas and uses low-carb swaps to keep things light but satisfying. A quick homemade enchilada sauce adds depth without hidden sugars, and a blend of cheeses creates the perfect, bubbly top.
Using pre-cooked shredded chicken saves time, and layering everything in a casserole dish keeps cleanup easy. The end result is hearty, flavorful, and totally keto-friendly.

How to Store
Let leftovers cool to room temperature, then cover the dish or transfer to airtight containers. Refrigerate for up to 4 days. For longer storage, portion into freezer-safe containers and freeze for up to 2 months. Reheat in the oven at 325°F (165°C) until warmed through, or microwave individual portions. If reheating from frozen, thaw overnight in the fridge for best texture.
Benefits of This Recipe
- Low in carbs, high in flavor: You get the enchilada experience without the blood sugar spikes.
- Protein-packed: Chicken and cheese make this filling and satisfying.
- Make-ahead friendly: Assemble in the morning and bake at dinnertime, or freeze for later.
- Family-approved: Even picky eaters love the cheesy, saucy layers.
- Flexible ingredients: Works with zucchini slices, cauliflower tortillas, or no “tortillas” at all.
What Not to Do
- Don’t use sugary sauces: Many canned enchilada sauces have added sugar.
Choose a low-carb brand or make your own.
- Don’t skip resting time: Cutting in too soon makes the layers slide apart and look messy.
- Don’t overbake: Too long in the oven dries out the chicken and splits the cheese.
- Don’t slice zucchini too thick: Thick slices release water and make the casserole watery. Aim for thin, even slices.
- Don’t forget to season: Taste your sauce and chicken mixture—salt brings everything to life.
Alternatives
- Protein swap: Use shredded turkey, ground chicken, or cooked ground beef seasoned with the same spices.
- Sauce change: Try a green enchilada (salsa verde) version with pepper jack cheese and extra cilantro.
- Dairy-light option: Reduce cheese by half and add more sauce. Use lactose-free cream cheese if needed.
- Veggie boost: Layer in sautéed bell peppers or spinach (well-drained) to add fiber without many carbs.
- No “tortilla” version: Skip the layers entirely and just build chicken, creamy sauce, enchilada sauce, and cheese.
It still slices well after resting.
FAQ
How do I make a quick low-carb enchilada sauce at home?
Simmer 2 tablespoons avocado oil with 2 tablespoons chili powder for 30 seconds. Whisk in 1 tablespoon tomato paste, 1 teaspoon cumin, 1/2 teaspoon oregano, 1/2 teaspoon smoked paprika, a pinch of cayenne, 1 1/2 cups chicken broth, and salt to taste. Cook 5–7 minutes until slightly thickened.
Taste and adjust seasoning.
Can I use rotisserie chicken?
Yes. Rotisserie chicken is ideal and saves time. Just remove the skin, shred the meat, and season it in the skillet so it picks up those enchilada spices.
Will zucchini make the casserole watery?
It can if sliced too thick or layered too heavily.
Slice thinly, salt lightly, and pat dry. You can also grill or roast the slices for a few minutes to drive off moisture before layering.
Is this recipe spicy?
It’s mildly spicy as written. To make it hotter, add extra chili powder, a pinch of cayenne, or sliced jalapeños.
To make it milder, reduce the chili powder and use mild green chiles.
What cheese melts best here?
Monterey Jack and cheddar melt beautifully and bring great flavor. Pepper jack is a nice option if you want a gentle kick. Pre-shredded works, but shredding your own melts creamier.
How can I make it even lower in carbs?
Skip any tortilla layers, use a no-sugar enchilada sauce, and avoid starchy add-ins.
Focus on chicken, sauce, and cheese, plus low-carb toppings like avocado and sour cream.
Can I assemble this ahead of time?
Yes. Assemble up to 24 hours in advance, cover, and refrigerate. Add 5–10 minutes to the baking time if the casserole goes into the oven cold.
What can I serve with it?
Try a simple side salad with lime vinaigrette, grilled zucchini, or cauliflower rice.
Keep sides light and fresh to balance the richness.
