Start things off by getting your oven warmed up to 400°F. In your 9×13 inch casserole dish, toss in the onion, bell pepper, uncooked rice, cayenne (if using), and fajita spice mix. Stir them all together until everything looks well spread out. This step sets us up with those mouthwatering smells and flavors.

Grab a bowl or measuring container and mix together the chicken stock, tomato paste, olive oil, and green chilies. Keep stirring it around until there are no lumps left. This broth mix is what brings all the flavors together while the rice fluffs up.

Pour your mixed broth right over the rice in the baking dish. Stir it all up so the liquid gets evenly absorbed into the dry mix. Then, toss in the shredded chicken, black beans, and corn. Mix it all just enough to combine without squishing it down too much.

Seal the casserole tightly with foil. Pop it in the oven and let it cook for about 1 hour and 5-10 minutes. Check to make sure the rice has soaked up all the broth and is soft. If using brown rice, keep an eye on it—it takes longer than white rice to finish.

Carefully pull the dish out of the oven and lift the foil (watch out for steam!). Sprinkle the shredded Monterey Jack evenly across the top. The hot rice should start melting the cheese, but we want to bake it again so the cheese gets all gooey and browned.

Pop the uncovered dish back into the oven. Give it 5-10 minutes for the cheese to fully melt and get a bit golden in spots. Pull it out and let it sit on the counter for another 5-10 minutes before digging in. Add some garnishes like avocado slices, green onions, or salsa for extra color and tastiness if you’d like.
