Ingredients 

  • 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

How to Make Sour Cream and Onion Smashed Potato Casserole – Step by Step

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.

Helpful Tips 

  • 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 bacon bits, caramelized onions, or sautéed mushrooms to make it a unique casserole creation.

Cooking Tips 

  • Use starchy potatoes like russet for the fluffiest texture.
  • Warm your milk and sour cream before adding to prevent cooling down the potatoes.
  • Mash by hand for a rustic texture. Avoid using a food processor to prevent the potatoes from becoming gluey.

Serving Suggestions 

This creamy casserole pairs wonderfully with:

  • Roasted Chicken or Baked Ham
  • Grilled Vegetables like asparagus or bell peppers
  • Fresh Garden Salad with a tangy vinaigrette

To make it a complete meal, serve it with a side of crusty garlic bread and a glass of Chardonnay.
