Ingredients
- 2 pounds frozen diced hash brown potatoes, thawed
- 2 cups shredded cheddar cheese, divided
- 1 can (10.5 ounces) cream of chicken soup
- 1 cup sour cream
- 1/2 cup milk
- 1 packet (about 1 ounce) ranch seasoning mix
- 1/2 small onion, finely diced
- 3 tablespoons melted butter
- 1/2 teaspoon garlic powder
- 1/4 teaspoon black pepper
- 1/2 cup cooked and crumbled bacon (optional)
- 2 tablespoons chopped fresh parsley or green onions
How to Make Cheesy Ranch Potato Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9-by-13-inch baking dish with butter or nonstick cooking spray.
Step 2: Prepare the Creamy Mixture
In a large mixing bowl, combine the cream of chicken soup, sour cream, milk, ranch seasoning, melted butter, garlic powder, and black pepper. Whisk until smooth and creamy.
Step 3: Add the Potatoes
Add the thawed hash brown potatoes and diced onion to the bowl. Stir gently until the potatoes are evenly coated with the ranch mixture.
Step 4: Mix in the Cheese
Fold in 1 1/2 cups of shredded cheddar cheese. If using bacon, add the cooked and crumbled bacon and mix until everything is evenly distributed.
Step 5: Assemble the Casserole
Transfer the potato mixture into the prepared baking dish. Spread it evenly and sprinkle the remaining 1/2 cup of cheddar cheese over the top.
Step 6: Bake Until Golden and Bubbly
Bake uncovered for 45–55 minutes, or until the potatoes are tender and the cheese is melted and golden. If the top browns too quickly, loosely cover the dish with foil.
Step 7: Garnish and Serve
Remove the casserole from the oven and let it rest for about 5–10 minutes. Sprinkle with fresh parsley or green onions and serve warm.
Tips for the Best Cheesy Ranch Potato Casserole
- Thaw the hash browns: Removing excess moisture helps prevent a watery casserole.
- Use freshly shredded cheese: It generally melts more smoothly than pre-shredded cheese.
- Don’t overmix: Stir gently to keep the potato pieces intact.
- Check for tenderness: Cooking time may vary depending on the size of the potatoes and your baking dish.
- Add extra toppings: Crispy bacon, green onions, or a little Parmesan make delicious additions.
- Let it rest: A few minutes of resting helps the casserole set before serving.

How to Store and Reheat
Store leftover casserole in an airtight container in the refrigerator for up to 3–4 days.
To reheat, place individual portions in the microwave until heated through, or cover the baking dish with foil and warm in a 350°F (175°C) oven. Add a small splash of milk if the potatoes seem dry.
You can also assemble the casserole ahead of time, cover it, and refrigerate it before baking. For the best texture, bake it within 24 hours and allow a chilled casserole a little extra time in the oven.
