Ingredients

  

• 2 cups cooked, shredded chicken (rotisserie or poached)
• 1 (15-ounce) can black beans, drained and rinsed
• 1 cup frozen or canned corn, drained if canned
• 1 cup plain nonfat Greek yogurt (or 2% for extra creaminess)
• 1 cup salsa (choose your preferred heat level)
• 1 (10-ounce) can diced tomatoes with green chiles, drained
• 1 tablespoon olive oil
• 1 small yellow onion, diced
• 1 red bell pepper, diced
• 2 cloves garlic, minced
• 2 tablespoons taco seasoning (store-bought or homemade)
• 1/2 teaspoon ground cumin
• 1/2 teaspoon smoked paprika (optional, for depth)
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon black pepper
• 8 small corn tortillas, cut into strips (or use crushed baked tortilla chips)
• 1 1/2 cups reduced-fat shredded Mexican blend cheese (or cheddar/Monterey Jack)
• Fresh cilantro, chopped, for garnish
• Optional toppings: diced avocado, sliced jalapeños, lime wedges, extra salsa, hot sauce

Method

 

1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
2. Warm a large skillet over medium heat. Add olive oil, then sauté the onion and red bell pepper for 4–5 minutes until softened.
3. Stir in the garlic and cook for 30 seconds. Add the taco seasoning, cumin, smoked paprika, salt, and pepper. Cook 1 minute to bloom the spices.
4. Add the black beans, corn, and diced tomatoes with green chiles. Stir and warm through for 2–3 minutes.
5. In a large bowl, combine the shredded chicken, salsa, and Greek yogurt. Fold in the warm bean-corn mixture. Taste and adjust salt if needed.
6. Layer half the tortilla strips evenly across the bottom of the baking dish. Spoon on half of the chicken mixture, then sprinkle with one-third of the cheese.
7. Repeat with the remaining tortillas and chicken mixture. Top with the remaining cheese.
8. Bake uncovered for 20–25 minutes, until the casserole is bubbly and the cheese is melted with golden spots.
9. Let it rest for 10 minutes to set. Garnish with cilantro and add any optional toppings before serving.

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

3. Stir in the garlic and cook for 30 seconds.

   Add the taco seasoning, cumin, smoked paprika, salt, and pepper. Cook 1 minute to bloom the spices.

4. Add the black beans, corn, and diced tomatoes with green chiles. Stir and warm through for 2–3 minutes.
5. In a large bowl, combine the shredded chicken, salsa, and Greek yogurt.

   Fold in the warm bean-corn mixture. Taste and adjust salt if needed.

6. Layer half the tortilla strips evenly across the bottom of the baking dish. Spoon on half of the chicken mixture, then sprinkle with one-third of the cheese.
7. Repeat with the remaining tortillas and chicken mixture.

   Top with the remaining cheese.

Keeping It Fresh

• Storage: Cover and refrigerate for up to 4 days. Keep toppings like avocado and jalapeños separate until serving.
• Reheating: Warm individual portions in the microwave for 60–90 seconds, or reheat the whole dish at 325°F until hot.
• Freezing: Assemble without the fresh toppings, wrap tightly, and freeze up to 3 months.

  Thaw overnight in the fridge, then bake at 350°F until heated through.

• Keep tortillas from getting soggy: If you prefer a firmer bite, lightly toast tortilla strips in a dry skillet before layering.

Health Benefits

• High-quality protein: Chicken and black beans support muscle repair and keep you fuller for longer.
• Fiber-rich: Beans, corn, and veggies deliver fiber for digestion and steady energy.
• Lighter creaminess: Greek yogurt adds body and tang with extra protein and fewer calories than sour cream.
• Balanced macros: Protein, complex carbs, and healthy fats make it a complete, satisfying meal.
• Micronutrients: Bell peppers, tomatoes, and beans bring vitamin C, potassium, and antioxidants.

What Not to Do

• Don’t skip seasoning: Under-seasoned filling can taste flat. Taste as you go and adjust salt and spice.
• Don’t use watery salsa without draining: Excess liquid makes the casserole soupy. If your salsa is runny, spoon off a bit of liquid first.
• Don’t overbake: Too long in the oven dries out the chicken.

  Pull it when the cheese is melted and bubbly.

• Don’t add fresh toppings before baking: Avocado, cilantro, and jalapeños go on after to keep their color and bite.

Recipe Variations

• Spicy chipotle: Stir in 1–2 teaspoons minced chipotle in adobo for smoky heat.
• Low-carb swap: Replace tortillas with a layer of cauliflower rice or sliced zucchini (pat dry first).
• Extra protein boost: Add an extra 1/2 cup Greek yogurt or a can of pinto beans.
• Dairy-free: Use a dairy-free yogurt and your favorite vegan cheese. Check taco seasoning for hidden dairy.
• Veggie-loaded: Mix in sautéed spinach or zucchini for more greens.
• Crunchy topping: Sprinkle a handful of crushed baked tortilla chips during the last 5 minutes of baking.
• Skillet-to-oven method: If your skillet is oven-safe, assemble right in it to cut down on dishes.

FAQ

Can I use raw chicken instead of cooked?

Yes, but cook it first. Dice and sauté chicken with a little oil, salt, and pepper until fully cooked, then shred or chop and proceed with the recipe.

Starting with cooked chicken keeps timing predictable and texture tender.

What tortillas work best?

Corn tortillas give that classic taco flavor and hold up well. Flour tortillas get softer and can turn doughy, so if you use them, toast lightly first. Crushed baked tortilla chips also work for a sturdier, slightly crunchy layer.

How can I make it spicier without overwhelming the dish?

Use medium or hot salsa, add a pinch of cayenne, and top with sliced jalapeños.

You can also mix in a teaspoon of chipotle powder or hot sauce to the filling. Keep the yogurt as-is to balance the heat.

Can I make this ahead?

Absolutely. Assemble up to 24 hours in advance, cover, and refrigerate.

When ready to bake, add 5–10 extra minutes if going straight from the fridge, and watch for bubbly edges and melted cheese.

What cheese melts best here?

A Mexican blend melts smoothly and browns nicely. Monterey Jack or a 50/50 cheddar-Jack combo gives a great pull. Reduced-fat cheese works, but full-fat melts more evenly.

Is there a gluten-free option?

Yes.

Use corn tortillas and confirm your taco seasoning and salsa are gluten-free. Everything else in the base recipe is typically safe.

How do I keep leftovers from drying out?

Cover tightly and reheat gently. A splash of chicken broth or a spoonful of salsa stirred into your portion before reheating helps keep it moist without diluting flavor.

Can I add rice?

You can.

Fold in 1–1 1/2 cups cooked brown rice or cauliflower rice. If using regular rice, reduce tortilla strips slightly so the casserole doesn’t get too dense.
