Ingredients

• 2 cups cooked shredded chicken

• 3 cups cooked rice

• 1 tablespoon olive oil

• 1 small onion, finely chopped

• 1 red bell pepper, diced

• 1 green bell pepper, diced

• 2 cloves garlic, minced

• 1 can (10 ounces) diced tomatoes with green chilies

• 1 cup tomato sauce

• 1 cup sour cream

• 1 1/2 cups shredded cheddar cheese

• 1 1/2 cups shredded mozzarella or Monterey Jack cheese

• 1 teaspoon chili powder

• 1 teaspoon paprika

• 1 teaspoon ground cumin

• 1/2 teaspoon oregano

• Salt and black pepper, to taste

• 2 tablespoons chopped fresh cilantro

• 2 tablespoons sliced green onions

• Extra sour cream, for topping

Instructions

Start by preheating your oven to 375°F (190°C). Lightly grease a large baking dish and set it aside.

Next, heat the olive oil in a skillet over medium heat. Add the chopped onion, red bell pepper, and green bell pepper. Cook them for about 4 to 5 minutes, stirring now and then, until they soften and smell sweet and savory. Add the garlic and cook for another 30 seconds, just until fragrant.

Now build the flavor. Stir in the diced tomatoes with green chilies, tomato sauce, chili powder, paprika, cumin, oregano, salt, and black pepper. Let everything simmer together for 2 to 3 minutes so the spices can wake up and the mixture thickens slightly.

In a large bowl, combine the shredded chicken, cooked rice, sour cream, and the warm vegetable mixture. Add half of the cheddar cheese and half of the mozzarella or Monterey Jack. Stir everything together until it’s well mixed and creamy, with the cheese starting to melt into all those warm ingredients.

Spoon the mixture into your prepared baking dish and spread it out evenly. Sprinkle the remaining cheese over the top, making sure you get good coverage from corner to corner.

Slide the dish into the oven and bake for 20 to 25 minutes, until the cheese is melted, bubbly, and just starting to turn golden on top.

Once it comes out of the oven, let it rest for about 5 minutes. This gives everything a chance to settle and makes it easier to serve. Right before bringing it to the table, finish with chopped cilantro, sliced green onions, and a dollop of sour cream on top.

Presentation

This casserole looks especially inviting served straight from the baking dish, with that golden, bubbly cheese still warm and stretchy. A sprinkle of fresh cilantro and green onions over the top adds color and freshness, while a spoonful of sour cream makes each serving look extra creamy and irresistible.

For even more color, you can scatter a few diced fresh bell peppers on top just before serving. Pair it with tortilla chips, a crisp green salad, or sliced avocado on the side for a meal that feels full, bright, and welcoming.
