Prepare the Chicken: Cut the chicken breast into bite-sized pieces. Season the chicken pieces with salt, pepper, and paprika.
Cook the Chicken: In a large skillet or pan, melt 1 Tbsp of butter over medium heat. Add the seasoned chicken pieces to the skillet. Cook until the chicken is seared, golden brown and cooked through (about 5-7 minutes). Once done, remove the chicken from the skillet and set it aside.
Sauté the Vegetables: In the same skillet, add the remaining 1 Tbsp of butter. Add the chopped onion and minced garlic to the skillet. Sauté until the onions are translucent and the garlic is fragrant (about 2-3 minutes).
Add Rice and Seasoning: Stir in the white long grain rice, ensuring that the rice is fully coated with the butter and sautéed onions. Add the dry ranch seasoning mix and chicken bouillon powder and stir to evenly distribute it throughout the rice.
Cook Rice: Pour in the chicken broth and bring the mixture to a boil. Once boiling, reduce the heat to low, cover the skillet, and let the rice simmer for about 15 minutes, or until most of the liquid is absorbed and the rice is tender.
Add Cheese, Broccoli and Chicken: Add 1 cup of cheese, the chopped broccoli and cooked chicken pieces to the skillet with the rice. Stir to combine, then cover the skillet again and let it cook for an additional 5-7 minutes, or until the broccoli is tender and the chicken is heated through.
Top with Cheese: Sprinkle the remaining cup shredded cheddar cheese over the chicken, rice, and broccoli mixture. Cover the skillet with a lid and let it sit for 1-2 minutes or until the cheese is melted.
