Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 6 Large Russet Potatoes – Peeled and diced into chunks
• ¼ Cup Unsalted Butter – Adds rich, smooth flavor
• 4 Ounces Cream Cheese – Softened to blend easily into the potatoes
• ⅔ Cup Sour Cream – For a tangy and creamy texture
• ½ Cup Whole Milk – Helps create the perfect consistency
• ½ Teaspoon Garlic Powder – Adds subtle depth of flavor
• Salt – To taste
• Black Pepper – To taste
• 2 Cups Shredded Sharp Cheddar Cheese – Divided, for inside the mix and on top
• ¼ Cup Diced Green Onions – For garnish and added freshness

Directions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with non-stick spray or butter.
2. Peel and dice the russet potatoes into medium-sized chunks. Add them to a large pot, cover with water, and bring to a boil. Cook until potatoes are fork-tender, about 10–15 minutes.
3. Drain the potatoes well and return them to the pot while still warm. Add the butter, cream cheese, sour cream, and milk. Gently fold the ingredients together. Avoid mashing completely—some chunks should remain for texture.
4. Add garlic powder, salt, and black pepper to taste. Stir in 1½ cups of the shredded cheddar cheese.
5. Transfer the mixture to the prepared casserole dish and spread evenly. Sprinkle the remaining ½ cup of cheddar cheese over the top.
6. Bake in the preheated oven for 25–30 minutes, or until the cheese on top is melted and bubbly.
7. Remove from the oven and sprinkle diced green onions over the top before serving.
