In this sumptuous twist on a classic, we elevate the humble potato to royal status, creating a Duchess Potatoes Casserole that combines the creamy richness of traditional Duchess Potatoes with the hearty, family-style comfort of a casserole.

Why You’ll Love This

This whipped potatoes recipe might change your side dish landscape. We all have had traditional mashed potatoes. I love ’em, to be honest.

But when we whipped (see what I did there?) these potatoes, we honestly didn’t realize that this might be the replacement for mashed potatoes going forward. They’re that good.

When we say decadent, it’s really not an exaggeration. This dish has heavy cream, butter, egg yolks, and Pecorino Romano cheese in it. If you’re looking for a low-calorie dish, this isn’t one of them. They’re worth the cheat, though, I promise.

This recipe is a nod to the elegance of Duchess Potatoes, reimagined as a cozy casserole that’s perfect for family dinners. It’s where culture meets comfort food.

Additionally, this dish makes a perfect side for almost any main course. This is to include a typical weekday meal or at the holiday table.

A tradition for me at the holidays always includes mashed potatoes. This year, these will be gracing our table.

Key Ingredients

This easy mashed potatoes recipe only calls for a handful of simple ingredients. The final product nails it. Perfect mashed potatoes!

  • Potatoes – We use a mix of Russet potatoes and Yukon Gold potatoes for fluffy whipped potatoes. Yukon golds add the desired creaminess to the potatoes.
  • Liquids – Unsalted butter, heavy cream (heavy whipping cream), and eggs.
  • Seasonings – Pecorino Romano cheese, kosher salt, and freshly ground black pepper.

How To Make Whipped Potatoes

The dish itself is not that complicated. With the exception of a few more ingredients and how it’s cooked, it comes together pretty quickly.

  • Peel and dice all your potatoes into 1-inch pieces. Place them in a large stockpot (any large pot will do) and cover them with cold water (cool water is fine, too).

Add one tablespoon of kosher salt and bring it to a boil over medium heat on a low boil.

Cook the potatoes for approximately 10 minutes or until fork-tender.

  • While the potatoes are boiling, melt the butter in a small saucepan over medium to medium-high heat. Cook the butter, stirring often until the butter begins to brown and become fragrant. This takes around 5 minutes.

Once lightly browned, remove the butter from the saucepan and place it into a bowl, and set aside.

  • When the potatoes are ready, drain them and return them to the pot or mixing bowl. Add 1/2 cup of the cream and blend until smooth with a hand mixer.

  • Add one egg yolk and beat into the potatoes. Once incorporated, add the other egg yolk and beat until combined well. Slowly add the browned melted butter, discarding any burned bits, and continue to combine with a hand mixer.

Once the butter has been incorporated, add the Pecorino Romano cheese, 1/2 teaspoon of freshly ground black pepper, two teaspoons of kosher salt, and the remaining 1/2 cup of heavy cream and beat until smooth.

  • Put your oven on high broil and place the oven rack approximately 8 inches from the heat. Depending on your oven, broil the potatoes until the top is browned, approximately 5-6 minutes.
  • Once browned, remove from oven and garnish with chopped chives and freshly ground black pepper.

Tips

Use a food mill or potato ricer for an even creamier experience.

Red potatoes are a good substitute for Yukon golds if you’re having an issue finding them.

Taste the salted water when cooking your potatoes. It should taste like the ocean.

You can use whole milk versus heavy cream to save some calories.

For a thicker mashed potato texture, use a touch less milk.

Variations

Herb-Infused Variation: Add fresh herbs like rosemary, thyme, or sage to the potatoes while boiling. This will infuse them with a fragrant, herbal flavor, adding a new dimension to the dish.

Cheesy Twist: Incorporate different types of cheese such as Gruyère or sharp cheddar for a more robust flavor profile. This variation would add a depth of flavor and create a more indulgent casserole.

Garlic and Onion Version: Sauté finely chopped garlic and onions until caramelized and mix them into the mashed potatoes before baking. This would add a sweet and savory element to the dish, enhancing its overall taste.

FAQ’s

What’s the difference between mashed and whipped potatoes?

Mashed potatoes have a little butter and some milk, typically mashed with a potato masher. Whipped potatoes are beaten with an electric mixer with lots of butter, heavy cream, and egg yolks.

How can I lighten these whipped potatoes with heavy cream?

Well, this is a very rich and decadent dish. If you must, you can try half and half instead of heavy cream. Maybe cut back on the butter a bit.

Storing Leftovers

Let the whipped mashed potatoes cool to room temperature, place in an air-tight container or cover with plastic wrap, and store in the refrigerator for up to 4 days.

Can you freeze whipped potatoes?

Yes! Let it come to room temperature, place it in a freezer-safe container or bag, and freeze for up to 2 months for best quality. When reheating you might need to add a little more butter or cream.
