Description

These comforting low-carb green chicken enchiladas deliver all the savory, cheesy satisfaction of a classic Mexican-inspired casserole without the heavy carb load. By using juicy chicken thighs and sneaking in fresh zucchini, the filling stays incredibly tender and flavorful. Making the bright, slightly spicy green chile sauce from scratch elevates the entire dish, though a high-quality store-bought version works perfectly in a pinch.

Instructions

Build the sauce base: Heat 1 tablespoon of avocado oil in a saucepan over medium heat. Sauté the diced onion and jalapeño for about 5 minutes, until the onions turn translucent and smell sweet—they should yield easily when pressed with a spoon. Stir in the minced garlic and cook for 1 minute until fragrant.
Simmer and blend: Add the green chiles, chicken broth, cumin, salt, and oregano to the saucepan. Bring the mixture to a rapid boil, then reduce the temperature to medium-low heat and let it simmer gently for 10 minutes to meld the flavors. Carefully transfer the mixture to a blender, add the fresh lime juice, and blend for about 1 minute until completely smooth. Set the sauce aside.
Season the chicken: Pat the chicken thighs thoroughly dry with paper towels to ensure they brown properly in the pan. In a small bowl, whisk together the kosher salt, black pepper, cumin, garlic powder, chili powder, and smoked paprika. Rub this spice blend evenly over both sides of each chicken piece.
Sear the chicken and zucchini: Heat 2 tablespoons of avocado oil in a large skillet over medium heat. Cook the chicken for 6 to 7 minutes per side, until deeply browned and the internal temperature reaches 165°F on a meat thermometer. Transfer the chicken to a clean plate to cool. Drain all but a thin layer of oil from the skillet, return to the heat, and sauté the diced zucchini for 3 to 4 minutes, until tender-crisp and brightly colored. Once the chicken has cooled, dice it and toss it with the zucchini in a large mixing bowl.
Roll the enchiladas: Preheat your oven to 350°F. Pour ½ cup of the green enchilada sauce into the bottom of a 9×13-inch baking dish, spreading it to the edges. Spoon about ⅓ cup of the chicken and zucchini mixture into each tortilla, sprinkle 1 tablespoon of cheese inside, and roll tightly. Place the rolled tortillas seam-side down in the baking dish.
Bake and broil: Pour the remaining green sauce evenly over the top of the enchiladas, ensuring the edges of the tortillas are covered so they don’t dry out. Scatter the remaining cheese over the top. Bake uncovered at 350°F for 20 minutes, until the sauce is visibly bubbling around the edges. Switch the oven to broil for 2 to 3 minutes, watching closely, until the cheese is gooey and speckled with golden-brown spots. Let the dish rest for 5 minutes before serving.

Notes

Why It Works

Using chicken thighs instead of breasts ensures the filling remains incredibly juicy, even after searing and baking.
The fresh lime juice added at the end of the sauce preparation provides a crucial pop of acidity that balances the richness of the cheese and chicken.
Sautéing the zucchini in the leftover chicken spices infuses it with smoky flavor while keeping its texture distinct.

Common Pitfalls to Avoid

Blending hot liquids: Always vent the lid of your blender when pureeing the hot sauce to prevent steam pressure from blowing the lid off. Cover the vent lightly with a clean kitchen towel to catch splatters.
Soggy tortillas: Don’t let the assembled, unbaked enchiladas sit around for too long before putting them in the oven, or the low-carb tortillas may absorb too much liquid and break apart.
Dry edges: Ensure the top layer of sauce covers the outer ends of the rolled tortillas before baking; exposed edges will turn hard and brittle in the oven.

Variations

Heat level: For a spicier kick, leave the seeds in the jalapeño or swap one can of mild green chiles for a fire-roasted or hot variety.
Speed it up: If you’re short on time, substitute the raw chicken thighs with 3 cups of shredded rotisserie chicken. Simply toss the cooked meat with the spices and warm it through in the skillet before mixing with the zucchini.

Allergy Alert

This recipe contains dairy (cheese) and potentially gluten (depending on the brand of low-carb tortillas used). Substitute with a melting vegan cheese and certified gluten-free tortillas as needed.
