Ingredients
Method
- Heat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with a little oil or nonstick spray.
- Sauté the veggies: Warm oil in a large skillet over medium heat. Add onion and bell peppers, and cook 5–7 minutes until softened. Stir in garlic and cook 30 seconds more.
- Season the veggie mix with chili powder, cumin, smoked paprika, oregano, salt, and pepper. Stir to coat and remove from heat.
- Mix the creamy base: In a large bowl, combine softened cream cheese, sour cream, 1 cup of shredded cheese, and half of the enchilada sauce. Beat until smooth. Fold in the diced green chiles.
- Add the chicken: Stir shredded chicken into the creamy mixture until evenly coated.
- Layer the casserole: Spread half of the seasoned veggies in the baking dish. Spoon half the chicken mixture over them. Pour a little sauce over the top and sprinkle with a handful of cheese. Repeat with remaining veggies, chicken, a generous layer of sauce, and the rest of the cheese.
- Bake uncovered for 20–25 minutes, until the casserole is bubbling and the top is lightly browned.
- Rest and garnish: Let it sit for 5–10 minutes to set. Top with cilantro, green onions, and jalapeño slices if you like.
- Serve with simple sides: a green salad, sliced avocado, or cauliflower rice.
Why This Recipe Works
This casserole keeps carbs low by skipping tortillas and using flavorful veggies and sauce to create layers. Shredded chicken soaks up the enchilada sauce, so every bite is savory and satisfying.
A blend of cheeses melts into a creamy blanket that holds the casserole together without needing starch. Best of all, it’s easy to prep ahead, and the leftovers reheat like a dream. You get the taste of enchiladas, minus the carb-heavy wrappers.

- Freezer: Portion into airtight containers.

Health Benefits
- Low in net carbs: Skipping tortillas and using low-carb sauce keeps this dish keto-friendly.
- High in protein: Chicken and cheese help with satiety and muscle maintenance.
- Balanced fats: Dairy and olive oil provide fats that support ketosis and keep you full.
- Micronutrients: Bell peppers, onions, and chiles add vitamin C, antioxidants, and fiber with minimal carbs.
Pitfalls to Watch Out For
- Sugary sauces: Many enchilada sauces contain added sugar or flour. Read labels and choose a low-carb option with clean ingredients.
- Watery casserole: If veggies release lots of moisture, the casserole can get soupy.
Sauté until most liquid cooks off, and let the casserole rest after baking.
- Overbaking: Too long in the oven can dry out the chicken. Bake just until bubbling and browned.
- High-carb add-ins: Skip corn, beans, or tortilla chips if you want to stay strict keto.
Recipe Variations
- Green enchilada version: Swap red sauce for salsa verde or green enchilada sauce. Add a squeeze of lime and extra cilantro.
- Spicy chipotle: Stir 1–2 chopped chipotle peppers in adobo into the sauce for smoky heat.
- Veggie boost: Add sautéed mushrooms or zucchini (well-cooked to drive off moisture) for more volume and fiber.
- Dairy-light: Use full-fat Greek yogurt instead of sour cream and reduce cheese by 1/2 cup.
It will still be creamy.
- Skillet shortcut: Build the casserole in an oven-safe skillet to cut down on dishes. Sauté, layer, and bake in the same pan.
- Rotisserie rescue: Use store-bought rotisserie chicken for fastest prep.
FAQ
Can I use raw chicken instead of cooked?
It’s best to use cooked, shredded chicken so the casserole bakes quickly and evenly. If using raw chicken, cook it first by poaching or roasting, then shred before mixing with the sauce.
What’s a good low-carb enchilada sauce?
Look for sauces with no added sugar and minimal thickeners.
Many health-focused brands offer low-carb options. You can also make your own with tomato sauce, chili powder, cumin, garlic, onion powder, and a little beef or chicken broth.
How can I reduce the dairy?
Swap sour cream for full-fat Greek yogurt and reduce the total cheese by 1/2 to 1 cup. Add a bit more chicken broth to the sauce if needed.
The texture will be slightly lighter but still rich.
Is this casserole gluten-free?
Yes, as long as your enchilada sauce and spices are gluten-free. Always check labels to avoid hidden thickeners or gluten-containing additives.
Can I make it ahead?
Yes. Assemble the casserole up to the baking step, cover, and refrigerate for up to 24 hours.
Add 5–10 extra minutes to the bake time if going into the oven cold.
What can I serve with it that’s still keto?
Great sides include cauliflower rice, shredded lettuce with avocado and lime, or roasted zucchini. A dollop of guacamole or a spoonful of pico de gallo adds freshness without extra carbs.
How do I keep it from being too spicy?
Use mild enchilada sauce and skip the jalapeños. Diced green chiles are usually mild, but you can reduce or omit them if you’re sensitive to heat.
Can I use canned chicken?
You can, though the texture is softer.
Drain it very well and mix gently to avoid mushiness. Adding a bit less sauce can help keep the structure intact.
What cheese melts best?
Monterey Jack and cheddar are reliable. Pepper Jack adds a gentle kick.
Avoid pre-shredded cheese if possible, as anti-caking agents can affect melt; shred your own for best results.
How many net carbs per serving?
It varies by sauce and veggies, but typically around 5–8 net carbs per serving. For accuracy, enter your specific ingredients into a nutrition calculator.
