Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. In a large bowl, whisk together Greek yogurt, salsa, chicken broth, green chiles, chili powder, cumin, smoked paprika, garlic powder, salt, and pepper until smooth.
3. Stir in chicken, black beans, corn, bell pepper, and onion. Taste and adjust salt if needed. IMO, a pinch more smoked paprika never hurts.
4. Spread half the tortilla strips on the bottom of the baking dish. Pour in half the chicken mixture. Sprinkle with half the mozzarella and cheddar.
5. Add the remaining tortilla strips and the rest of the chicken mixture. Top with the remaining cheese. Press down gently to settle everything.
6. Bake uncovered for 22–28 minutes, until bubbly around the edges and the top turns golden.
7. Let it rest for 8–10 minutes so it sets. Squeeze fresh lime juice over the top and add your favorite toppings. Slice, serve, and accept the compliments.

Smart Swaps And Easy Upgrades

Save

Keep It Lean

• Use nonfat Greek yogurt to shave a few calories.
• Swap some cheese for cotija crumbs for big flavor with less melt.

Pack More Veg

• Add zucchini or spinach to the mix. Sauté first to avoid extra moisture.
• Roast the peppers and corn for a smoky edge. Small effort, huge payoff.

Spice Level: Choose Your Fighter

• Mild: Use mild salsa and skip jalapeños.
• Medium: As written. Trust the balance.
• Hot: Add chipotle in adobo and a dash of cayenne. Live dangerously.

Serving Ideas That Win Dinner

• Bowl style: Spoon over cilantro-lime rice or cauliflower rice.
• Crunch factor: Top with crushed baked tortilla chips right before serving.
• Fresh finish: Pico de gallo, extra lime, and a dollop of yogurt or sour cream.
• Party mode: Serve with a simple romaine and avocado salad. Balanced and bougie.

FAQ

Can I use leftover grilled chicken instead of rotisserie?

Absolutely. Shred or cube it and follow the recipe as-is. If it tastes a little dry, add an extra splash of broth in the sauce. The casserole will still hit all the right notes.

Do I need the tortilla layer?

Nope, but it adds that cozy casserole texture. If you prefer low-carb, skip tortillas and spoon the filling into a dish, then bake with cheese on top. It becomes a killer chicken-and-bean bake.

What kind of salsa works best?

Chunky medium salsa brings the best balance. If you use a super watery salsa, reduce the broth by a few tablespoons. Thick, fire-roasted salsa delivers great depth, IMO.

How do I prevent a soggy casserole?

Drain beans well, thaw and pat dry frozen corn, and don’t go rogue with extra liquid. Let it rest after baking so the layers set. Also, avoid covering it while it bakes so moisture can escape.

Can I make it dairy-free?

Yes. Use a thick dairy-free yogurt (like coconut or almond-based), swap cheese for a melty dairy-free option, and check your tortillas. It still tastes fantastic with the spices doing the heavy lifting.

What sides pair well with this?

Simple slaw with lime and cumin, roasted sweet potatoes, or a citrusy salad. Keep it fresh and bright to balance the richness. Chips and guac never hurt anyone either.
