Ingredients

2 pounds new potatoes, halved
1 packet (1 ounce) ranch seasoning mix
1 cup sour cream
2 cups shredded cheddar cheese, divided
2 tablespoons olive oil

Instructions

Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish with olive oil or cooking spray.
Add the halved new potatoes to the baking dish. Drizzle with olive oil, sprinkle with ranch seasoning, and toss until every potato is evenly coated.
Cover the dish tightly with aluminum foil and bake for 35 minutes, or until the potatoes begin to soften.
Remove the foil. Stir in the sour cream and 1½ cups of shredded cheddar cheese until the potatoes are coated in a creamy, cheesy sauce.
Sprinkle the remaining ½ cup cheddar cheese over the top and bake uncovered for another 15–20 minutes, until the cheese is melted, bubbly, and lightly golden.
Let the casserole rest for 5–10 minutes before serving to allow the sauce to thicken.

Recipe Benefits
