Step-by-Step Instructions

Step 1: Preheat and prep

Preheat your oven to 375°F (190°C). Lightly grease a 9×13” baking dish.

Step 2: Cook the potatoes

Toss diced potatoes in olive oil, garlic, salt, and pepper. Spread on a baking sheet and roast for 20 minutes, or until lightly golden and fork-tender.

Step 3: Mix the base

In a large bowl, combine the roasted potatoes, cooked chicken, steamed broccoli, sour cream, milk, and half of the cheese. Season with onion powder, salt, and pepper. Mix well.

Step 4: Bake the casserole

Transfer the mixture into the prepared baking dish. Sprinkle remaining cheese over the top. Cover with foil and bake for 20 minutes, then uncover and broil for 2–3 minutes to brown the cheese (optional).

Let the casserole rest for 5 minutes. Top with bacon or green onions if desired.
