High-Protein Chicken Enchilada Casserole (Low-Carb Meal Prep)

Traditional chicken enchiladas are pure comfort food, but they are often loaded with extra carbs and heavy oils that leave you sluggish. This High-Protein Chicken Enchilada Casserole delivers all the bold, cheesy, Tex-Mex flavor you love while significantly boosting the protein and keeping the carb count manageable. By layering lean shredded chicken breast, low-carb corn-and-wheat tortillas, and a rich blend of sharp cheddar and Greek yogurt-infused red enchilada sauce, you get a warm, satisfying meal that fits perfectly into your fitness goals.

Why This Recipe Works

  • 42g of Protein Per Serving: Uses lean chicken breast and a high-protein cheese sauce blend to keep you full for hours.
  • Meal-Prep Friendly: Reheats exceptionally well without turning soggy, making it ideal for weekday lunches.
  • Smart Carb Swaps: Low-carb tortilla strips absorb the sauce like traditional tortillas without spiking blood sugar.
  • Simple Pantry Staples: No complicated techniques—just simple assembly and an easy bake.

Key Ingredients & Roles

  • Cooked Shredded Chicken Breast: The primary protein anchor. Using poached or rotisserie chicken breast saves prep time while keeping fat low.
  • Red Enchilada Sauce: Look for a low-sugar red sauce with robust chili powder, cumin, and garlic notes.
  • Plain Non-Fat Greek Yogurt: Mixed into the enchilada sauce to create a velvety, rich texture and add extra protein without heavy cream.
  • Low-Carb Tortillas: Cut into wide strips to create structural layers that hold the sauce and chicken together.
  • Diced Green Chilies: Adds subtle heat and authentic tangy flavor throughout the casserole.
  • Reduced-Fat Sharp Cheddar & Monterey Jack: Sharp cheddar provides maximum flavor payoff with less total fat, while Monterey Jack melts smoothly.

Cooking & Assembly Tips

1. Blend the Sauce for Smooth Creaminess: Whisking the Greek yogurt into room-temperature enchilada sauce prevents curdling and yields a luxurious, cream-like sauce base.

2. Layer Evenly: Start with a thin coating of sauce on the bottom of the baking dish. This keeps the bottom layer of tortilla strips soft and prevents sticking.

3. Don't Over-Bake: Since the chicken is already fully cooked, baking is primarily to melt the cheese and heat the layers through. Keep it to 22–25 minutes at 375°F (190°C) so the chicken remains tender.

Frequently Asked Questions

Can I use raw chicken breast for this casserole?
It is best to use pre-cooked, shredded chicken breast. If using raw chicken, cook and shred it before assembling to ensure proper cooking times and prevent excess liquid from watering down the casserole.

How do I keep low-carb tortillas from getting soggy?
Baking at 375°F (190°C) without foil for the final 10 minutes helps excess moisture evaporate, keeping the tortillas firm yet tender.

Can I make this dairy-free?
Yes. Use a plant-based unsweetened Greek-style yogurt alternative and your favorite dairy-free melting cheese shreds.

Is this dish suitable for strict Keto diets?
Yes, as long as you use low-carb tortillas (typically 3–4g net carbs each) and a low-sugar red enchilada sauce, each portion fits comfortably within daily keto macro limits.

  • 1 tsp ground cumin
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder

  • 6 low-carb flour or corn-wheat blend tortillas, cut into 1-inch strips
  • 1 cup (112g) reduced-fat sharp cheddar cheese, shredded

  • 2 tbsp fresh cilantro, chopped (for garnish)

Equipment Needed

  • 9x13-inch baking dish
  • Large mixing bowl

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C). Lightly spray a 9x13-inch baking dish with non-stick cooking spray.
  2. Make Sauce: In a large mixing bowl, whisk together the red enchilada sauce, Greek yogurt, diced green chilies, cumin, garlic powder, onion powder, and salt until smooth and combined.

  6. Assemble Second Layer: Repeat with the remaining tortilla strips, remaining chicken mixture, and the remaining reserved sauce poured evenly over top. Finish with the rest of the shredded cheese.
  7. Bake: Bake uncovered at 375°F (190°C) for 22–25 minutes until the casserole is bubbly around the edges and the cheese is fully melted and lightly golden.
