Ingredients
Method
- Preheat and prep: Heat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with olive oil or butter.
- Sauté aromatics (optional but recommended): In a skillet over medium heat, add a little oil. Cook the onion and bell pepper with a pinch of salt until softened, 4–5 minutes. Stir in the garlic for 30 seconds. Remove from heat.
- Make the creamy taco sauce: In a mixing bowl, combine cream cheese, sour cream, tomato paste, taco seasoning, and chicken broth. Whisk until smooth. Taste and adjust salt, pepper, or seasoning.
- Combine the filling: In a large bowl, add shredded chicken, sautéed veggies, green chiles, and 1 cup of shredded cheese. Pour the sauce over and mix until everything is coated.
- Assemble the bake: Spread the mixture evenly in the prepared baking dish. Top with the remaining 1 cup of cheese.
- Bake: Place in the oven for 18–22 minutes, until the edges are bubbling and the cheese is melted.
- Broil for color (optional): Switch to broil for 1–2 minutes to brown the top slightly. Watch closely so it doesn’t burn.
- Rest and garnish: Let the bake rest 5–10 minutes so it sets. Top with cilantro, green onions, sliced jalapeño, and diced avocado if you like. Serve with lime wedges.
- Serve ideas: Spoon into bowls with a side salad, pile onto shredded lettuce, or serve with low-carb tortillas or cheese crisps for scooping.
What Makes This Recipe So Good
- Big taco flavor, low carbs: You get the zesty spice blend, melty cheese, and all the toppings—without the carb-heavy shells.

Add optional toppings so everyone can customize.

Keeping It Fresh
- Storage: Cool completely, then cover or transfer to airtight containers. Refrigerate for 3–4 days.
- Reheating: Microwave individual portions for 60–90 seconds, or warm in a 325°F (165°C) oven until hot.
Add a splash of broth if it seems dry.
- Freezing: Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge, then reheat. For best texture, add fresh toppings after reheating.
- Meal prep tip: Bake in two smaller dishes.
Eat one now, freeze the other.
Health Benefits
- High in protein: Chicken provides steady energy and supports muscle maintenance, keeping you satisfied longer.
- Ketogenic-friendly fats: Cream cheese, sour cream, and cheese deliver fats that help you stay within keto macros and feel full.
- Low in carbs: No tortillas or beans here. Using tomato paste and optional veggies keeps carbs in check while adding flavor.
- Nutrient boosts: Avocado and cilantro add fiber, potassium, and antioxidants. Bell peppers contribute vitamin C if you include them.
Pitfalls to Watch Out For
- Hidden sugars: Many store-bought taco seasonings contain sugar or starch.
Choose a sugar-free blend or make your own.
- Too much liquid: If your chicken is very moist, pat it dry. Drain green chiles well. Otherwise, the bake can turn soupy.
- Salt overload: Between cheese, seasoning, and broth, sodium can add up.
Taste the sauce before adding extra salt.
- Overbaking: This can dry out the chicken. Pull it when the cheese is melty and the edges bubble, then let it rest to set.
- Carb creep from toppings: Tomato-heavy salsa or sweetened hot sauces can bump carbs. Check labels and portion sizes.
Variations You Can Try
- Spicy chipotle: Add 1–2 teaspoons chipotle in adobo (minced) to the sauce and use pepper jack on top.
- Fajita-style: Swap taco seasoning for fajita seasoning and load up on sautéed bell peppers and onions.
- Green enchilada twist: Stir in 1/3 cup sugar-free salsa verde and finish with Monterey Jack and fresh lime.
- Cauliflower layer: Add a base of riced cauliflower (lightly sautéed and well-drained) for extra bulk with minimal carbs.
- Tex-Mex bake: Add chopped bacon and a pinch of smoked paprika.
Top with a dollop of guacamole at serving.
- Dairy-light: Use reduced amounts of cheese and swap sour cream for full-fat Greek yogurt. Still creamy, just a little lighter.
- Turkey or pork: Replace chicken with leftover turkey or shredded pork carnitas for a new spin.
Can I Make This Ahead?
Yes. Assemble the casserole up to the cheese topping, cover, and refrigerate for up to 24 hours.
When ready to bake, let it sit at room temperature for 15–20 minutes, then bake as directed, adding a few extra minutes if needed.
Is This Recipe Gluten-Free?
It can be. Most ingredients are naturally gluten-free, but check your taco seasoning and broth for hidden gluten. Use certified gluten-free products to be safe.
How Many Carbs Per Serving?
Exact carbs vary with brands and optional veggies.
A typical serving lands around 5–7 net carbs without high-carb toppings. For accuracy, plug your exact ingredients into a nutrition calculator.
What If I Don’t Have Rotisserie Chicken?
Poach chicken breasts in salted water or broth until just cooked, then shred. Or roast thighs for extra juiciness.
Leftover grilled chicken works well too.
Can I Use Low-Fat Dairy?
You can, but full-fat dairy makes the sauce richer and more keto-friendly. If using low-fat, watch for added starches and expect a slightly thinner texture.
How Do I Make My Own Taco Seasoning?
Mix 2 teaspoons chili powder, 1 teaspoon cumin, 1 teaspoon smoked paprika, 1/2 teaspoon oregano, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/4 teaspoon cayenne, plus salt and pepper to taste. Double or triple and store airtight.
What Toppings Work Best?
Think low-carb and fresh: diced avocado, sliced jalapeño, chopped cilantro, green onions, a squeeze of lime, and a spoon of sour cream.
Use sugar-free hot sauce if you like heat.
