Ingredients

Scale

4 pounds russet potatoes, peeled and cut into 1-inch pieces
1 cup sour cream
1/2 cup whole milk
1/4 cup unsalted butter, melted
1 cup shredded cheddar cheese
1/2 cup sliced green onions, plus more for garnish
Salt and pepper to taste
1/2 teaspoon garlic powder
1/4 teaspoon paprika

Optional substitutions:

For a lighter version, use Greek yogurt instead of sour cream.
Use almond milk instead of whole milk for a dairy-free option.
Substitute vegan butter for unsalted butter to make it vegan-friendly.

Instructions

Step 1: Preheat Your Oven

Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius) to ensure an even bake throughout the casserole.

Step 2: Prepare the Potatoes

Place the peeled and diced potatoes into a large pot and cover them with cold water. Bring to a boil over high heat, then reduce the heat and simmer for about 15-20 minutes or until the potatoes are tender when pierced with a fork.

Pro Tip: For extra creamy potatoes, use a potato ricer instead of a masher.

Step 3: Drain and Mash

Drain the potatoes and return them to the pot. Add the sour cream, milk, melted butter, garlic powder, paprika, salt, and pepper. Use a potato masher or a fork to smash the potatoes until well combined, leaving some texture for that homemade feel.

Step 4: Add the Cheese and Onions

Fold in the shredded cheddar cheese and sliced green onions, mixing until they are evenly distributed throughout the mixture.

Step 5: Assemble and Bake

Transfer the potato mixture to a greased 9×13 inch casserole dish and smooth out the top using a spatula. Bake in the preheated oven for 20-25 minutes until the top is golden and the edges are bubbly.

Notes

For a crispy top: Sprinkle additional shredded cheddar cheese over the top before baking.
Make it ahead: You can prepare the casserole up to 2 days in advance and refrigerate it. When ready to serve, bake as directed.
Customize it: Add crispy chekin bits, caramelized onions, or sautéed mushrooms to make it a unique casserole creation.
