This is, without a doubt, our favorite way to prepare potatoes.

We love all kinds of potatoes, from classic french fries to best-ever mashed potatoes. But, folks, these luscious potatoes are like none you’ve ever made or served before. Fondant is French for “melting” and they literally melt in your mouth. They are what you would call a “special occasion” dish, but you’ll want to make them constantly, after one bite.

The Ingredients You Will Need

Believe it or not, there are just a handful of ingredients for these spectacular potatoes. There are couple of ingredients, that put them in a league of their own, starting with the duck fat. Here’s what you’ll need to have on hand:

Potatoes – Starchy is what you want. Gold or Russet work great. Outside North America: Sebago and King Edward are great choices.
Fat or Oil – Duck fat is our recommendation. It can be found in many supermarkets, including Whole Foods. Bacon grease will work, too, as well as pork lard. Vegetable oil will even work.
Seasonings – Salt and pepper is all you need.
Butter – Unsalted, cubed.
BrothHomemade chicken stock is great, but store-bought is just fine. Vegetable broth works great, too.
Garlic – Whole cloves, cut in half, lengthwise.
Herbs – Sprigs of thyme are perfect.
Coarse salt – Any kind of finishing salt is excellent. Coarse sea salt works, Maldon Flakey Sea Salt is wonderful.

EXPERT TIP: To form perfect cylinders, use a 1½” cookie cutter to cut a 2″ tall piece of circular potato (2nd photo below). Or, peel each potato, cut the ends off, and then use a sharp knife to form a 2-inch cylinder (1st photo below).

Tips for Making Perfect Potatoes Fondant

Use the Right Potatoes – Use a starchy potato such as Russet or Yukon Gold for the best texture. Don’t use waxy potatoes, such as red potatoes.

Cut the Potatoes Evenly – Cut the potatoes into even, thick slices to ensure that they cook evenly and have a consistent texture. A cookie cutter makes this a snap. Use excess potatoes to make mashed potatoes.

Use a Combination of Oil and Butter – Use a combination of unsalted butter and oil to cook the potatoes, which will give them a nice crispy texture and rich flavor. Duck fat delivers incredible taste.

Baste the Potatoes – Basting the potatoes with the cooking liquid during the cooking process and then right after will help to keep them moist and tender, and add flavor.

How To Cook Fondant Potatoes

Think of cooking the potatoes like searing meat or sea scallops. You’ll start them off in a hot skillet with oil, preferably duck fat.

You can move them around occasionally in the skillet, especially if there are hot spots over the heat. They should turn a nice golden color before you flip them and sear the other side.

Finishing them off in the oven with butter, garlic, herbs, and stock allows the potatoes to absorb the liquid (except the oil) and become extremely tender (hence the name: Fondant, which translates to ‘melting’).

Baste at least once during the baking process.

How To Serve

When you and your family try these potatoes, you’ll immediately understand why these are considered a “special occasion” dish.

They are spectacular to serve alongside a steak at an elegant dinner party. They are also wonderful to serve family-style during the holiday season.

But, honestly, they are so simple to prepare, they are fun to whip up for a Sunday night dinner at home.

You can plate them along side the main protein (ie, steak) and then serve. Or, you can do what we like to do, and place them all on a platter and then drizzle the sauce over the potatoes and top with herbs and sea salt.

Potatoes Fondant are called "melting potatoes" because they do just that...they melt in your mouth. If you can't find duck fat, then go with bacon grease or just plain vegetable oil. You'll still have stunning potatoes.

  • Sturdy skillet that can go in the oven such as a cast-iron skillet


  • 4 lbs potatoes starchy, such as russet or gold
  • 3 tbsp duck fat see NOTES, divided
  • Salt and pepper
  • 4 tbsp unsalted butter cubed
  • 4 cloves garlic peeled and cut in half, lengthwise, and then smashed with the side of a knife
  • 3 sprigs thyme fresh
  • cups chicken stock
  • coarse sea salt for finishing


  • Preheat oven to 400°F.
  • Peel the potatoes, and then cut the ends off of each side. Use a sharp knife to cut the potato into 1 to 2-inch cylinders. Use a sharp knife to shave off the edges to make straight-edge cylinders, or use a 1½" cookie cutter to cut out the cylinders. (See the video for reference). Save excess potatoes to make mashed potatoes.
    4 lbs potatoes
  • Place the potatoes in a large bowl. Add 1 tbsp of the duck fat and season liberally with salt and pepper. Toss the potatoes to fully coat. Set aside.
    3 tbsp duck fat, Salt and pepper
  • Heat the remaining 2 tbsp duck fat in a large oven-safe skillet over medium-high heat. Place the potato cylinders into the skillet and sauté until golden brown on the underside, moving occasionally to achieve even browning, about 7 to 8 minutes.
  • Turn each potato and sear again for another 7 to 8 minutes (moving occasionally) until browned.
  • Add the butter, garlic, thyme, and chicken stock to the pan and bring to a boil. Remove from the heat and place in the oven for 20 minutes. After 10 minutes, spoon the sauce over the potatoes. After 20 minutes, most of the liquid should be gone, leaving only the butter.
    4 tbsp unsalted butter, 4 cloves garlic, 3 sprigs thyme, 1½ cups chicken stock
  • Remove from oven and discard the garlic and thyme. Spoon the sauce over the tops of the potatoes.
  • Plate the potatoes, and then spoon more of the butter sauce over the top. Garnish on top with a little chopped thyme and a sprinkling of the coarse salt. Serve at once.

Duck fat can be found in many well-stocked supermarkets near where shortening and oils are sold. Whole Foods sells it. Bacon grease, pork lard, or even vegetable oil can be used in place of duck fat. 
These potatoes are best served warm, but they are still delicious at room temperature. 
The potatoes can be cut and then kept in water for several hours before proceeding with the recipe. Be sure to pat them dry completely.
