Step-by-Step Instructions
Step 1: Prep the Oven and Dish
Preheat your oven to 350°F (175°C). Spray an 8×10-inch casserole dish with nonstick spray to prevent sticking.
Step 2: Cook the Rice
In a saucepan, bring 3 cups of water to a boil. Add 1 ½ cups of long-grain white rice, reduce to a simmer, and cover. Cook according to package instructions until the rice is tender and yields about 4 cups.
Step 3: Prepare the Chicken
While the rice is cooking, cut your **chicken breast** into ½-inch cubes. Season with ½ teaspoon of salt and ½ teaspoon of pepper.
Step 4: Sear the Chicken
Heat a large skillet over medium-high heat. Add 1 tablespoon of olive oil and the seasoned chicken cubes. Sear for about 2 minutes on each side until lightly browned. Transfer the chicken to a large bowl.
Step 5: Sauté the Vegetables
In the same skillet, add the diced onion and carrots. Sauté for about 5 minutes until softened. Add them to the bowl with the chicken.
Step 6: Make the Sauce
Using the same skillet, melt 3 tablespoons of butter over medium heat. Add 3 tablespoons of flour, whisking constantly until the mixture becomes foamy. Cook for about 1 minute to eliminate the raw flour taste.
Step 7: Add Liquids to the Sauce
Slowly whisk in 1 cup of chicken broth, allowing the mixture to simmer and thicken. Gradually add 1 cup of whole milk, whisking continuously until the sauce coats the back of a spoon.
Step 8: Season the Sauce
Turn off the heat and stir in 1 teaspoon of smoked paprika, ½ teaspoon of garlic powder, and ½ teaspoon of onion powder. Mix well with the remaining salt and pepper.
Step 9: Combine All Ingredients
In the bowl with the chicken and vegetables, add the broccoli florets, cooked rice, and half of the shredded cheddar cheese (about 1 cup). Pour in the sauce and mix until everything is well combined.
Step 10: Assemble the Casserole
Transfer the mixture to the prepared casserole dish. Smooth out the top and sprinkle the remaining shredded cheese evenly over the mixture.
Step 11: Bake
Bake in the preheated oven for about 35 minutes, or until the edges are golden brown and the cheese is bubbly.
Step 12: Serve
Serve hot as a hearty, protein-packed meal. Perfect for post-workout recovery or a comforting family dinner.
Common Mistakes to Avoid
Here are a few pitfalls to watch out for when making this casserole:
- Overcooking the chicken: Searing should be brief to prevent dryness. Aim for just a light browning.
- Undercooked rice: Ensure the rice is fully cooked before adding it to the casserole to avoid crunchy bites.
- Runny sauce: Allow the sauce to thicken properly before combining with other ingredients. It should coat the back of a spoon.
How to Store & Reheat
To store leftovers, allow the casserole to cool completely. Transfer to an airtight container and refrigerate for up to 4 days. For longer storage, freeze for up to 3 months. To reheat, preheat the oven to 350°F (175°C) and warm the casserole until heated through, about 20-25 minutes. If reheating from frozen, allow it to thaw overnight in the refrigerator first.
