Ingredients
1 pound boneless skinless chicken breasts, cut into 1-inch pieces
1 tablespoon olive oil
1 medium yellow onion, thinly sliced
1 teaspoon salt, divided
1/2 teaspoon black pepper, divided
1 cup long-grain white rice, rinsed
1 can (10.5 ounces) condensed French onion soup
1 1/2 cups chicken broth
1 cup shredded Swiss cheese
1/2 cup shredded mozzarella cheese
2 cloves garlic, minced
1/4 cup grated Parmesan cheese
2 tablespoons unsalted butter
Instructions
Preheat the oven to 350°F (175°C).
In a large skillet, heat olive oil over medium heat. Add the sliced onion and 1/2 teaspoon salt. Cook, stirring occasionally, until onions are soft and caramelized, about 15 minutes.
Add minced garlic to the onions and cook for an additional 1 minute until fragrant. Remove from heat and set aside.
In a large mixing bowl, combine the chicken pieces, rinsed rice, condensed French onion soup, chicken broth, caramelized onions with garlic, remaining 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Stir well to combine.
Lightly grease a 9×13-inch casserole dish with butter.
Pour the mixture into the prepared casserole dish and spread evenly.
Sprinkle shredded Swiss cheese and mozzarella cheese evenly over the top.
Cover the casserole tightly with aluminum foil.
Bake in the preheated oven for 40 minutes.
Remove the foil and sprinkle grated Parmesan cheese over the casserole.
Return the casserole to the oven uncovered and bake for an additional 5 minutes, or until the cheese is melted and bubbly.
Remove from oven and let the casserole rest for 5 minutes before serving.
