Description
A hearty and nutritious high-protein chicken rice casserole packed with tender chicken, brown rice, and vegetables, perfect for a wholesome family meal.
Ingredients
2 cups cooked brown rice
1.5 pounds boneless skinless chicken breasts, cut into bite-sized pieces
1 tablespoon olive oil
1 medium onion, diced
3 cloves garlic, minced
1 cup low-sodium chicken broth
1 cup plain Greek yogurt
1 cup shredded reduced-fat cheddar cheese
1 cup frozen peas
1 cup chopped carrots
1 cup chopped broccoli florets
1 teaspoon dried thyme
1 teaspoon dried oregano
1/2 teaspoon black pepper
1/2 teaspoon salt
Instructions
Preheat the oven to 375°F (190°C).
Heat olive oil in a large skillet over medium heat. Add diced onion and cook for 3-4 minutes until softened.
Add minced garlic and cook for 1 minute until fragrant.
Add the chicken pieces to the skillet and cook for 5-7 minutes, stirring occasionally, until the chicken is no longer pink on the outside.
In a large mixing bowl, combine cooked brown rice, cooked chicken mixture, chicken broth, Greek yogurt, shredded cheddar cheese, frozen peas, chopped carrots, chopped broccoli, dried thyme, dried oregano, black pepper, and salt. Mix well until all ingredients are evenly combined.
Transfer the mixture into a greased 9×13 inch casserole dish and spread it out evenly.
Cover the casserole dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil and bake for an additional 10-15 minutes until the casserole is bubbly and the cheese is melted and slightly golden.
Remove from the oven and let it rest for 5 minutes before serving.

In terms of equipment, you just need a good skillet and a baking dish—nothing fancy, nothing complicated. I usually like to serve this with a simple green salad to add a little crunch and freshness. If you want to switch things up, sometimes I swap out the peas for green beans or add a handful of chopped mushrooms, though I haven’t tested all these variations thoroughly, so it’s a bit of a culinary experiment. For a bit more warmth, a sprinkle of smoked paprika can add a nice twist, though I keep it pretty classic most of the time.
FAQ
Can I use white rice instead of brown? You can, but brown rice adds a nuttier flavor and more fiber, which balances the richness of the casserole.
Is it freezer-friendly? Yes, leftovers freeze well. Just thaw overnight before reheating.
Can I use other vegetables? Definitely. Carrots, broccoli, peas are great, but feel free to add your favorites.
How do I know when it’s done? When the cheese is bubbly and golden, and the chicken is cooked through, it’s ready.
