3-Ingredient Holiday Ranch Potato Casserole
Ingredients
| Ingredient | Quantity |
|---|---|
| Frozen diced hash brown potatoes, thawed | 1 bag (32 oz) |
| Sour cream | 1 container (16 oz) |
| Dry ranch seasoning mix | 1 packet (1 oz) |
Instructions
Step 1: Preheat and Prepare the Pan
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or oil.
Step 2: Make the Ranch Mixture
In a large bowl, whisk together the sour cream and ranch seasoning until smooth and fully blended.
Step 3: Combine the Potatoes
Add the thawed hash brown potatoes to the bowl and gently fold until evenly coated with the ranch mixture. Spread the mixture into the prepared baking dish and press lightly to level it.
Step 4: Bake
Bake uncovered for 40–50 minutes, until the edges are bubbling and the top turns lightly golden.
Step 5: Cool and Serve
Let the casserole rest for 5–10 minutes before serving so it sets slightly and is easier to scoop.
