• 15 oz can black beans, drained: Adds fiber and protein; rinse well to cut sodium by 40%.
• 1 cup fire-roasted corn kernels: Frozen works great—thaw first for better texture integration.
• 10 oz can diced tomatoes with green chiles: Rotel-style for built-in spice; mild if feeding kids.
• 2 cups shredded reduced-fat cheddar: Melts perfectly; Mexican blend adds extra zing.
• 1 packet low-sodium taco seasoning: Or homemade with chili powder, cumin, garlic powder, onion powder, and paprika.
• 1 cup salsa verde: Tangy green variety brightens flavors; use your favorite heat level.
• 2 cups cooked brown rice: Keeps it hearty and healthy; quinoa swaps in easily.
• 1 bell pepper, diced: Red or yellow for sweetness that balances the spice.

Step-by-Step Instructions

Step 1: Prep Chicken and Veggies

Preheat oven to 375°F and lightly grease a 9×13-inch baking dish. Shred cooked chicken breasts (or dice raw ones), then toss with black beans, corn, diced tomatoes with chiles, bell pepper, brown rice, taco seasoning, and salsa verde until evenly coated—the mixture should look vibrant and saucy.

Step 2: Layer and Bake

Spread everything evenly in the prepared dish, then sprinkle shredded cheddar over the top. Bake uncovered for 25-30 minutes until cheese bubbles and turns golden brown around the edges—it should smell irresistibly smoky and spicy.

💡 Pro Tip: For extra crisp, broil on high for 2 minutes at the end, watching closely to avoid burning.

Step 3: Rest and Serve

Remove from oven and let sit 5 minutes—the casserole sets up so slices hold together perfectly, with steam releasing juicy flavors.

Common Mistakes (And How to Fix Them)

• Soggy Casserole: Use cooked rice and drain beans/corn thoroughly; bake uncovered to evaporate excess moisture.
• Dry Chicken: Shred pre-cooked rotisserie chicken or add 1/4 cup chicken broth to the mix for built-in moisture.

Storage & Reheating

• Fridge: Covers tightly for up to 5 days.
• Freezer: Portion into airtight containers for up to 3 months; thaw overnight before reheating.
• Reheating: Microwave 2-3 min or oven at 350°F for 15 min until hot (165°F internal).

Serving Suggestions

• Top with fresh avocado slices, cilantro, and a squeeze of lime for creamy contrast.
• Serve alongside tortilla chips for scooping or a simple green salad.

Is this casserole spicy?

Mild to medium depending on your salsa and tomatoes; swap mild versions or add diced jalapeños post-bake for heat control.​
