How to Make It

Each step is simple and relaxed no rushing, no complicated techniques perfect for cozy weeknight cooking or calm weekend meal prep.

Preheat & Build the Base

Preheat your oven to 400°F and grab a 9×13-inch baking dish.
Add the diced onion, bell pepper, uncooked rice, fajita seasoning, and cayenne pepper if using. Stir everything together so the rice is evenly coated and ready to soak up all that flavor.

This step sets the stage for a nourishing homemade meal that cooks together in one dish.

Whisk the Savory Sauce

In a separate bowl or large measuring cup, whisk together the chicken broth, green chilies, tomato paste, and olive oil until smooth.
This mixture becomes the cozy, flavorful backbone that keeps the casserole moist and comforting while it bakes.

Combine & Stir

Pour the broth mixture directly into the baking dish and stir to combine with the rice mixture.
Then gently fold in the shredded chicken, black beans, and corn until everything is evenly distributed.

At this point, you’ll already see how this becomes a balanced, protein-packed comfort meal with minimal effort.

Cover & Bake

Cover the dish tightly with aluminum foil and transfer it to the oven.
Bake for 65–70 minutes, allowing the rice to absorb the liquid and the flavors to meld into a hearty, family-style dinner.

This slow bake makes it ideal for meal prep for busy days when you want dinner to mostly take care of itself.

Add the Cheese

Remove the casserole from the oven and carefully take off the foil.
Sprinkle the shredded Monterey Jack cheese evenly over the top, then return the dish to the oven uncovered for 5–10 minutes, just until the cheese melts and turns lightly golden.

That bubbly top layer is pure cozy comfort.

Rest & Serve

Let the casserole rest for 5–10 minutes before serving.
Finish with fresh cilantro, green onions, salsa, or sliced avocado if desired perfect for customizing plates at the table.
