Keto Chicken Enchilada Casserole – A Cozy, Low-Carb Comfort Dinner
Ingredients
- 3 cups cooked shredded chicken (rotisserie chicken works well)
- 1 medium zucchini, sliced lengthwise into thin ribbons (or 6–8 thin egg wraps/low-carb tortillas)
- 1 cup red enchilada sauce (no-sugar-added)
- 1/2 cup sour cream
- 1 1/2 cups shredded cheese (Mexican blend, Monterey Jack, or cheddar)
- 1/2 small onion, finely diced
- 1 small bell pepper, diced (any color)
- 1–2 tablespoons olive oil
- 1 teaspoon ground cumin
- 1 teaspoon chili powder
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon garlic powder
- Salt and pepper to taste
- Optional toppings: sliced avocado, chopped cilantro, green onions, pickled jalapeños, lime wedges
Instructions
- Preheat the oven: Set your oven to 375°F (190°C). Lightly grease a 9×9 or 9×13 baking dish, depending on how thick you want the layers.
- Prep the zucchini: Use a mandoline or vegetable peeler to slice the zucchini lengthwise into thin ribbons. Lay them on paper towels and sprinkle a little salt to draw out moisture. Pat dry after 10 minutes. If using egg wraps or low-carb tortillas, skip this step.
- Sauté the veggies: Heat olive oil in a skillet over medium. Add the onion and bell pepper with a pinch of salt. Cook 4–5 minutes until softened. Stir in cumin, chili powder, smoked paprika, and garlic powder. Cook 30 seconds to bloom the spices.
- Make the sauce mix: In a bowl, whisk enchilada sauce with sour cream until smooth. Taste and adjust salt and pepper. This creates a creamy, clingy sauce that keeps the casserole moist.
- Toss the chicken: In a large bowl, combine shredded chicken with the sautéed veggies and half of the sauce mixture. Stir to coat everything evenly.
- Layer the casserole: Spoon a thin layer of the remaining sauce into the bottom of the baking dish. Add a layer of zucchini ribbons (or egg wraps/tortillas), overlapping slightly. Spread half the chicken mixture over the top. Add a handful of cheese. Repeat with another layer of zucchini, the rest of the chicken, and more cheese.
- Top and bake: Finish with a final layer of zucchini or wraps, the remaining sauce, and the rest of the cheese. Cover loosely with foil (tent it so it doesn’t stick to the cheese) and bake for 20 minutes. Remove foil and bake another 10–15 minutes until bubbly and golden at the edges.
- Rest and garnish: Let the casserole sit for 10 minutes so it sets and slices cleanly. Top with chopped cilantro, green onions, and optional jalapeños. Add avocado and a squeeze of lime at the table.
- Serve: Slice into squares and plate with a crisp green salad or cauliflower rice for a complete meal.
What Makes This Special

- Flexible: Works with leftover chicken or turkey, and you can adjust heat and toppings easily.

Pitfalls to Watch Out For
- Watery casserole: Zucchini holds moisture. Salt and pat it dry, and let the baked casserole rest before slicing.
- Soggy layers: Avoid over-saucing each layer. A little sauce goes a long way when cheese melts.
- Hidden sugars:</-strong> Choose a no-sugar-added enchilada sauce to keep carbs down.
Check labels carefully.
- Overcooking: Too long in the oven can make zucchini mushy. Bake just until bubbling and cheese is melted.
- Too mild or too spicy: Taste your sauce and adjust spices before layering so the flavors are balanced.
Variations You Can Try
- Green enchilada version: Swap red sauce for salsa verde or green enchilada sauce, add a pinch of cumin and coriander, and use Monterey Jack cheese.
- Creamy chipotle: Blend the sauce with 1–2 teaspoons adobo sauce from chipotle peppers for smoky heat.
- Buffalo twist: Mix a few tablespoons of buffalo sauce into the chicken and use ranch drizzle on top.
- Vegetable boost: Add sautéed mushrooms or spinach to the chicken mixture to bulk it up with minimal carbs.
- Dairy-light: Use less cheese and swap sour cream for full-fat Greek yogurt if you tolerate it.
- Tortilla feel: Use thin egg wraps or low-carb tortillas instead of zucchini for a more traditional texture.
FAQ
Can I use raw chicken instead of cooked?
Yes, but cook it first for food safety and texture. Poach, roast, or pressure-cook the chicken until done, then shred and proceed with the recipe.
What’s the best cheese for melting?
A Mexican blend or Monterey Jack melts beautifully and gives that gooey factor.
Cheddar adds sharpness but can be a bit oilier—mixing cheeses works well.
Is store-bought enchilada sauce okay on keto?
It can be. Look for a no-sugar-added sauce with simple ingredients. Many brands keep carbs low per serving; read the label to be sure.
How do I keep it from getting watery?
Salt and pat your zucchini dry, don’t overload with sauce, and let the casserole rest after baking.
These steps make a big difference.
Can I make this spicy?
Absolutely. Add diced jalapeños to the sautéed veggies, use a hot enchilada sauce, or stir in chipotle in adobo for smoky heat.
What sides go well with this?
A simple green salad with lime vinaigrette, cauliflower rice, or sautéed green beans keeps it light and keto-friendly.
Can I make it dairy-free?
Yes, use a dairy-free cheese that melts well and swap sour cream for a creamy, unsweetened dairy-free alternative. The texture will change slightly but still works.
How many carbs per serving?
Exact numbers vary by sauce, cheese, and wraps used.
With zucchini layers and no-sugar-added sauce, you can expect roughly 5–7 net carbs per serving. Always calculate with your specific ingredients.
