Step‑by‑Step Instructions for Baked Potato Chicken and Broccoli Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that by the time you’ve prepared your ingredients, the oven is hot and ready for roasting. A properly heated oven will give your potatoes that delightful golden color and crispiness that makes the Baked Potato Chicken and Broccoli Casserole so irresistible.
Step 2: Prepare Potatoes
In a large bowl, toss diced potatoes with olive oil, salt, and black pepper until they are well coated. This step is crucial as the seasoning enhances the potato’s natural flavor. You want the pieces to glisten with oil for the best roasting results. Once mixed, they are ready to spread on a baking sheet.
Step 3: Roast Potatoes
Spread the seasoned potatoes evenly on a baking sheet and roast them in the preheated oven for 20–25 minutes. Check for doneness; they should be golden brown and tender when pierced with a fork. Rotating the baking sheet halfway through will help achieve even browning, ensuring every bite of your casserole is flavorful.
Step 4: Cook Broccoli
While the potatoes are roasting, bring a pot of water to a boil or prepare your steamer. Add the broccoli florets and cook for 4–5 minutes until just tender yet still bright green. This step retains the broccoli’s vibrant color and nutrients, making your Baked Potato Chicken and Broccoli Casserole a wholesome dish.
Step 5: Cook Chicken
In a medium saucepan, melt butter over medium heat. Add shredded or diced cooked chicken to the pan, heating it through for about 3–5 minutes. This step is essential for ensuring the chicken is warm and flavorful, which is a key component in the hearty layers of your casserole.
Step 6: Mix Sauce
In a mixing bowl, combine sour cream, milk, garlic powder, onion powder, and half of the shredded cheddar cheese. Stir until smooth and well-blended. This creamy sauce will enrich the textures of your Baked Potato Chicken and Broccoli Casserole, providing that gooey goodness we all love.
Step 7: Layer Ingredients
In a greased casserole dish, start layering your roasted potatoes, followed by the cooked chicken and then the steamed broccoli. Ensure an even distribution for every spoonful to have a taste of each ingredient. This colorful layering will make your casserole not only delicious but visually appealing as well.
Step 8: Add Sauce
Pour the creamy sauce mixture evenly over the layered ingredients. Using a spatula, gently fold the layers together to combine without breaking the potatoes. This step ensures that every bite of the Baked Potato Chicken and Broccoli Casserole is infused with that rich flavor of the sauce.
Step 9: Top with Cheese
Sprinkle the remaining cheddar cheese and grated Parmesan cheese generously on top. This layer of cheesy goodness will melt beautifully in the oven, creating a golden, bubbly crust that is absolutely irresistible. Make sure to cover the casserole well so each portion has that delightful cheese pull.
Step 10: Bake
Reduce the oven temperature to 350°F (175°C) and bake the casserole for 20–25 minutes. Keep an eye on it; the cheese should melt and begin to bubble around the edges, signaling that it’s time for a cozy dinner. The aroma of this Baked Potato Chicken and Broccoli Casserole will surely fill your kitchen with delight!
Step 11: Rest
Once baked, remove the casserole from the oven and let it rest for 5 minutes. This resting time allows the flavors to meld and the sauce to set, making it easier to serve. Your patience will be rewarded as the layers stay together beautifully on your plates.
Step 12: Garnish
For a touch of freshness, optional garnish with chopped fresh parsley before serving. This little green addition not only brightens the appearance of your Baked Potato Chicken and Broccoli Casserole but also adds a wonderful flavor contrast to the rich, cheesy layers beneath.
