Step‑by‑Step Instructions for Chicken Broccoli Rice Casserole
Step 1: Preheat Oven and Prepare Baking Dish
Begin by preheating your oven to 375°F (190°C). While the oven is heating, lightly grease a 9×9 inch baking dish with a bit of olive oil or cooking spray to ensure your Chicken Broccoli Rice Casserole won’t stick during baking.
Step 2: Sauté Onion and Garlic
In a skillet, heat 1 tablespoon of olive oil over medium heat. Once hot, add ¼ cup of diced onion. Sauté for about 3-4 minutes until the onion is soft and translucent. Add 2 cloves of minced garlic and cook for another 30 seconds, until the garlic is fragrant, which will elevate the aroma of your casserole.
Step 3: Combine Chicken, Rice, and Broccoli
In a large mixing bowl, combine 2 cups of shredded cooked chicken, 2 cups of cooled cooked rice, and 2 cups of steamed broccoli florets. Incorporate the sautéed onion and garlic into the mix, gently folding everything together until evenly combined. This combination forms the hearty base of your Chicken Broccoli Rice Casserole.
Step 4: Make the Creamy Sauce
In a separate bowl, whisk together 1 cup of plain Greek yogurt, ½ cup of low-sodium chicken broth, 1 teaspoon of salt, ½ teaspoon of freshly ground black pepper, and ½ teaspoon of smoked paprika. Mix until smooth and well-blended. This creamy sauce will add moisture and flavor to your casserole.
Step 5: Combine Ingredients with Sauce
Pour the creamy sauce over the chicken mixture in the large bowl. Use a spatula to stir gently, ensuring all the ingredients are well coated with the sauce. This step is crucial for making your Chicken Broccoli Rice Casserole rich and luscious in every bite.
Step 6: Transfer to Baking Dish and Add Cheese
Carefully transfer the combined mixture into the prepared baking dish, spreading it out evenly. Sprinkle ½ cup of shredded cheddar cheese and ¼ cup of freshly grated Parmesan cheese on top, giving your casserole a deliciously cheesy finish that will melt beautifully in the oven.
Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake uncovered for 20-25 minutes. You’ll know it’s ready when the edges are bubbling and the cheese is golden brown. For an extra crispiness, consider broiling it for an additional 2 minutes, but watch it closely to prevent burning.
