• 1 packet (1 oz) dry ranch seasoning mix

---

Instructions

Step 1: Preheat and Prep the Dish
Set your oven to 350°F (175°C). Grease a 9×13-inch baking dish with oil or cooking spray.

Step 2: Mix the Ranch Base
In a large bowl, stir together the sour cream and ranch seasoning until the mixture is smooth and uniform.

Step 3: Combine With the Potatoes
Add the thawed hash browns to the bowl and fold gently until every piece is evenly coated. Spread the mixture into the prepared baking dish, pressing it down slightly.

Step 4: Bake the Casserole
Bake uncovered for 40–50 minutes, or until the edges are bubbling and the top has a light golden color.

Step 5: Let It Rest and Serve
Allow the casserole to cool for 5–10 minutes so it sets up a bit, making it easier to scoop and serve.
