Whipped Potato Casserole is a decadent side dish that will elevate your holiday table. Each bite is pillowy, creamy, and full of flavor thanks to browned butter and extra-sharp cheese.
If you want a potato side dish that will wow your guests while remaining simple to prepare, this Whipped Potato Casserole is a perfect choice. It’s comforting, elegant, and one you’ll return to for holidays and special dinners.
This version was inspired by whipped potato recipes from Southern-style kitchens. The presentation is attractive and the texture—a light, cloud-like mash—makes it impossible not to dig in when it reaches the table.
These whipped potatoes practically melt in your mouth. Rich, creamy, and satisfying, they’ll earn approving looks from everyone gathered. The best part is the short ingredient list and easy steps. Let’s get started.
Simple Ingredients:
- Yellow potatoes – Yukon Golds are ideal for a naturally creamy, buttery texture.
- Brown butter – Browning the butter adds a nutty, caramelized depth of flavor.
- Half and half – Used here instead of heavy cream for a rich but balanced finish.
- Sharp cheddar – Extra-sharp white cheddar gives a pronounced cheesy punch.
- Egg yolks – Add silkiness and body to the potatoes; they improve texture noticeably.
- Seasonings – Salt, black pepper, and a touch of garlic powder.
- Green onion slices – For a fresh, bright garnish after broiling.
Substitutions:
- Potatoes – Russets or red potatoes can be used if Yukon Golds aren’t available.
- Butter – Browning the butter is optional; unbrowned butter still yields a delicious result but with a milder flavor.
- Cheese – Cheddar, Parmesan, or Gruyère are all good choices depending on the flavor you want.
How To Make Whipped Potato Casserole:
See full instructions in the recipe card below
Step One. Place peeled, cubed potatoes in a large pot with 1 tablespoon kosher salt and enough cold water to cover. Bring to a boil over medium-high heat and simmer until potatoes are fork-tender.
Step Two. While the potatoes cook, brown the butter: melt 12 tablespoons salted butter in a small saucepan over medium-high heat, stirring constantly until it turns a deep golden brown and develops a nutty aroma. Pour into a heatproof bowl and let it cool so the solids settle; reserve the clear browned butter and leave behind any sediment.
Step Three. Drain the cooked potatoes and return them to a large bowl. Add 1/2 cup of half-and-half and use a hand mixer to beat until mostly smooth. Add the egg yolks one at a time, mixing after each until incorporated. Stir in the reserved brown butter (avoiding the sediment), the shredded cheese, the remaining 1/2 cup half-and-half, and the seasonings.
Step Four. Beat the mixture gently with the hand mixer until the potatoes are light, fluffy, and mostly smooth—avoid overmixing to prevent a gummy texture. Transfer the whipped potatoes to a greased 9×13-inch baking dish, smooth into an even layer, and place under a preheated broiler about 8 inches from the heat source. Broil 5–6 minutes until the top is a deep golden brown. Remove and garnish with sliced green onions or chives.
Important Tips:
- Cooking potatoes: Make sure potatoes are fully cooked and very tender so they whip to a smooth texture.
- Whipping: Avoid overmixing—stop when potatoes are fluffy and smooth. A few small lumps are fine; the cheese will melt under the broiler.
- Brown butter: Let the browned butter cool so the solids sink. Use only the clear butter for the best flavor and texture.
- Room temperature ingredients: Bring the half-and-half, egg yolks, and cheese to room temperature before mixing to ensure a silky finish.
Common Questions:
If potatoes are lumpy, they were likely undercooked. Cook until a fork passes through them effortlessly.
Yes. Prepare through the mixing step, cool completely, cover, and refrigerate up to one day. When ready, bring to room temperature 30 minutes, bake at 350°F for 35–40 minutes until heated through, then broil 5–8 minutes to brown the top.
Yes. Adding yolks to very warm potatoes effectively heats them and provides a safe, creamy result.
No. Egg yolks add richness and texture without imparting an eggy flavor.

Whipped Potato Casserole
Equipment
-
1 large stock pot
-
1 small sauce pot
-
1 9×13-inch baking dish
Ingredients
- 4 pounds Yukon gold potatoes, peeled and cut in 1 inch cubes
- 1 tablespoon kosher salt
- 1 ½ sticks salted butter, 12 tbsp
- 1 cup half and half, divided, at room temperature
- 3 large egg yolks, room temperature
- 1 cup shredded extra sharp white cheddar cheese, at room temperature
- 1 ½ teaspoon kosher salt
- 1 teaspoon ground black pepper
- ¼ teaspoon garlic powder
- sliced green onions or chives for garnish
Instructions
-
Add prepared potatoes to a large pot along with 1 tablespoon of kosher salt. Fill pot with just enough cold water to cover the potatoes. Place pot on the stove and turn heat to medium high and bring to a medium boil. Cook potatoes until fork tender. You want the fork to effortlessly go through the potatoes.
-
Meanwhile make brown butter. Add 12 tablespoon butter to a small sauce pot over medium-high heat. Bring to a light simmer and use a whisk to constantly stir butter until it turns a deep golden brown. This takes about 5-6 minutes. When the butter is browned pour into a heat proof bowl and allow to cool and rest.
-
Set your oven rack about 8 inches from the top heat source. Turn your broiler on high and allow it to heat.
-
When potatoes are cooked drain in a colander and transfer to a large bowl. Add ½ cup of half and half, then use a hand mixer to beat potatoes until mostly smooth. Add egg yolks one at a time, beating in-between until incorporated.
-
Next, pour in brown butter, making sure to leave behind the sediment at the bottom of the dish. Add 1 cup of cheese, remaining ½ cup of half and half, 1 ½ teaspoon kosher salt, 1 teaspoon pepper, and ¼ teaspoon garlic powder. Use hand mixer to blend until mostly smooth and potatoes are fluffy.
-
Transfer whipped potatoes to a greased 9×13-inch baking dish and spread out in an even layer. Place under the broiler for 5-6 minutes until deep golden brown. Make sure to keep an eye on it so the top doesn’t burn. Garnish with green onions slices or chives.
