Keto Chicken Enchilada Casserole
This cheesy, no-tortilla chicken enchilada casserole is a weeknight hero that comes together with rotisserie chicken and a quick cream cheese sauce. It bakes bubbly and golden with all the spicy, tangy flavors of classic enchiladas, minus the carbs.
If you’ve been missing the comfort of a good enchilada bake, this one will hit the spot without knocking you out of ketosis. It’s rich, it’s fast, and it reheats beautifully for lunch the next day.
Why This Casserole Works
The cream cheese and sour cream give the sauce a velvety texture that coats every shred of chicken. You really don’t miss the tortillas at all.
Using rotisserie chicken means the prep is mostly measuring and stirring. You can have it in the oven in about 15 minutes.
It tastes even better the next day, which makes it a great meal prep option for busy weeks.
Ingredients
- 2 cups shredded cooked chicken: rotisserie or poached, whatever you have on hand.
- 4 oz cream cheese, softened: full-fat for the best texture and keto macros.
- 1/2 cup sour cream: full-fat again; it keeps the sauce creamy.
- 1 cup red enchilada sauce: look for a low-carb brand with no added sugar (check the label).
- 1 can (4 oz) diced green chiles, drained: mild heat and a nice pop of flavor.
- 1 tsp ground cumin
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 2 cups shredded Mexican blend cheese, divided: cheddar jack or a similar mix works well.
- Salt and pepper to taste
- Optional: sliced black olives, chopped cilantro, and extra sour cream for serving.
Variations and Substitutions
- Swap the protein: shredded beef works just as well. Just make sure it’s cooked and ready to fold in.
- Add more heat: fold in some diced jalapeños or a pinch of cayenne with the green chiles.
- Dairy-free option: use dairy-free cream cheese and sour cream. The texture will be a little looser, but it still tastes great.
- No green chiles?: a diced fresh poblano or a small can of drained diced tomatoes with green chiles (Rotel) will do the job.

How to Make Keto Chicken Enchilada Casserole
Step 1: Mix the Creamy Sauce
Preheat your oven to 375°F (190°C) and lightly grease an 8×8 baking dish. In a large bowl, beat the 4 oz softened cream cheese, 1/2 cup sour cream, 1 cup enchilada sauce, 1 tsp cumin, 1/2 tsp garlic powder, and 1/2 tsp onion powder until smooth. Season with a pinch of salt and pepper, then fold in the 2 cups shredded chicken and the drained green chiles.
The mixture will be thick and creamy, with the green chiles speckled throughout. It smells a little like a taco night already.
Step 2: Layer the Casserole
Spread half of the chicken mixture evenly across the bottom of the prepared dish. Top it with 1 cup of the shredded cheese. Add the remaining chicken mixture on top, smoothing it out, then finish with the last cup of cheese.
You don’t need perfect layers. Just spread things out so every scoop gets a good ratio of chicken, sauce, and cheese.
Step 3: Bake Until Bubbly
Slide the dish into the preheated oven and bake for 20 to 25 minutes. You’ll know it’s ready when the edges are bubbling like crazy and the cheese is melted and just starting to turn golden.
If you want a more browned top, you’ll handle that in the next step. For now, a knife tip inserted in the center should come out hot, and the whole dish should look like it’s happily simmering.
Step 4: Broil and Serve
Switch the oven to broil and let the top get golden and blistered. This takes 1 to 2 minutes, so watch it closely. Pull the casserole out and let it rest for about 5 minutes so the layers settle a bit. Top with sliced olives, a handful of chopped cilantro, and maybe a dollop of sour cream. Serve it hot.
A Few Notes Before You Start
- Don’t skip the broil.: It gives the top layer of cheese those irresistible brown spots and a little crunch that contrasts with the creamy filling.
- Let it rest.: Those 5 minutes out of the oven help the casserole hold together when you scoop, instead of sliding apart on the plate.
- Full-fat dairy matters.: Low-fat sour cream or cream cheese can turn watery as they bake, which makes the casserole less creamy.
Storing Leftovers
- Refrigerate: store leftovers in an airtight container for up to 4 days.
- Reheating: a few minutes in the microwave works, or warm it gently in a 350°F oven until heated through.
- Freeze: you can freeze the unbaked, assembled casserole (covered tightly) for up to 3 months. Thaw overnight in the fridge and bake as directed, adding 10 extra minutes if needed.
What to Serve with Keto Chicken Enchilada Casserole
This casserole is rich, so I like something crisp and fresh on the side. A simple green salad with avocado and a lime vinaigrette cuts through the creaminess perfectly. Sautéed zucchini or a pile of warm cauliflower rice also work if you want a more substantial plate.
Frequently Asked Questions
Can I use fresh chicken instead of rotisserie?
Yes, absolutely. Poach or bake two medium chicken breasts until cooked through, then shred them while warm. You’ll need about 2 cups total.
My casserole turned out watery, what went wrong?
The most common culprit is a thin enchilada sauce. Some store-bought sauces are on the watery side. Next time, simmer the sauce in a small pan for a few minutes to thicken it before mixing. Also drain the green chiles well.
Is this recipe gluten-free?
It is, as long as you use a gluten-free enchilada sauce and check that your cheese shreds don’t include any starchy anti-caking additives. Most standard shredded cheese is fine, but it’s worth a glance.
Can I prepare it ahead of time?
Yes, assemble the casserole, cover it tightly, and refrigerate for up to 24 hours before baking. When you’re ready to cook, add an extra 5 to 10 minutes to the bake time since it’s starting cold.
