Equipment
- Large skillet or Dutch oven
- 9×13-inch baking dish
- Two forks or stand mixer for shredding chicken
- Instant-read thermometer (if cooking raw chicken from scratch)
Step-by-Step Instructions
Step 1: Cook and Shred the Chicken (12 minutes)
Heat olive oil in a large skillet over medium heat. Season chicken with salt and pepper and cook 6–7 minutes per side until internal temperature reaches 165°F (74°C). Transfer to a plate, rest 5 minutes, then shred with two forks.
Return skillet to medium heat. Sauté onion and bell pepper 4–5 minutes until softened. Add garlic, chili powder, and cumin; stir 30 seconds until fragrant. Return shredded chicken to the pan and toss to coat.
Step 2: Mix the Light Enchilada Filling (3 minutes)
In a large bowl, whisk Greek yogurt with 1 cup enchilada sauce until smooth. Fold in chicken mixture, black beans, corn, and half the cheese (3/4 cup). Stir in cilantro. Taste and adjust salt or spice—add a pinch of cayenne if you want more heat.
Step 3: Layer the Casserole (5 minutes)
Preheat oven to 375°F (190°C). Spread 1/2 cup enchilada sauce on the bottom of a greased 9×13-inch dish. Add one-third of the tortilla pieces, one-third of the chicken filling, and a drizzle of sauce. Repeat layers twice, ending with tortillas on top.
Pour remaining enchilada sauce evenly over the top and sprinkle with remaining cheese.
Step 4: Bake Until Bubbly (20–25 minutes)
Cover with foil and bake 15 minutes. Remove foil and bake 10–12 minutes more until cheese is golden and edges bubble. Let rest 5–10 minutes before serving so layers set when you scoop.
Step 5: Serve
Scoop portions with a large spoon and top with extra cilantro, a dollop of Greek yogurt, and lime wedges. Add jalapeño slices for heat lovers.
Serving Suggestions
- Classic: Spanish rice, refried beans, and simple shredded lettuce salad.
- Light: Cilantro-lime slaw and sliced avocado.
- Party: Set out toppings bar—diced tomato, onion, hot sauce, and extra cheese.
Tips for the Best Skinny Enchilada Casserole
- Do not skip the rest: Cutting too soon makes layers slide apart.
- Control moisture: Drain beans and corn well so the casserole is not soupy.
- Tortilla choice: Corn tortillas stay slightly firmer; flour gets softer and lasagna-like.
- Make ahead: Assemble unbaked, cover, and refrigerate up to 24 hours; add 10 minutes bake time.
Storage, Reheating, and Freezing
Refrigerate cooled leftovers in airtight containers up to 4 days. Reheat individual portions in the microwave covered, or warm the whole dish at 350°F until heated through.
Freeze baked portions up to 2 months. Thaw overnight in the fridge and reheat covered with a splash of enchilada sauce to restore moisture.
Substitutions and Variations
- Vegetarian: Swap chicken for 4 cups sautéed mushrooms and extra beans.
- Dairy-free: Use dairy-free yogurt and cheese shreds.
- Spicier: Stir in diced green chiles or use hot enchilada sauce.
- Lower carb: Replace half the tortillas with thin zucchini ribbons.
Recipe Checklist
- Cook chicken to 165°F before shredding.
- Drain beans and thaw corn to avoid excess liquid.
- Whisk Greek yogurt smooth with sauce before folding.
- Layer tortillas, filling, and sauce evenly in three passes.
- Cover for first half of baking, uncover to brown cheese.
- Rest 5–10 minutes before scooping.
- Garnish with cilantro and lime at the table.

Is skinny chicken enchilada casserole healthy?
It is lighter than traditional versions thanks to lean chicken, Greek yogurt, and reduced-fat cheese—while still delivering protein, fiber from beans, and satisfying cheese flavor.
