What are Duchess Potatoes?

Believed to be named after a British Duchess who visited France, these potatoes are more of a fancy cousin to mashed potatoes. Egg-yolk enriched and blended with delicious parmesan cheese, Duchess potatoes are piped into fancy golden domes and baked to picture perfection.

How do I store Duchess Potatoes?

These delicious potatoes can be prepped, piped, refrigerated, and then baked the following day. After baking, store in the refrigerator in an airtight container. They will stay well for four days.

Can I freeze Duchess Potatoes?

You totally can, but you don’t want to bake them and then freeze them. You want to pipe the potato mixture onto a parchment paper lined sheet tray. Then place the tray in a freezer. Leave in there for approximately 30-40 minutes.

For best results, wrap each mound of potatoes in freezer plastic wrap. This will stop them from sticking to each. Then you can place them in a freezer safe container or freezer bag. Pull out as many as you like when it’s meal time! They will last up to 2 – 3 months.

For best cooking results, remove from freezer and place in the fridge the day before you want to cook them.

Do I have to use a piping bag to make Duchess potatoes?

If you don’t own piping tools or don’t have the extra time, you can also spoon the potatoes onto the baking sheet and create decorative swirls with the tines of a fork.

What kind of potatoes should I use for Duchess Potatoes?  

The natural and firm texture of Yukon Gold Potatoes has always created the prettiest ridges. They also hold their shape better than most potato varieties.

Tips for Making Duchess Potatoes

  • If you can, avoid whipping the potatoes with a mixer. The potatoes may become gluier. A mixer with a dough attachment works really well!
  • Freezing the potato mounds for 15 minutes before baking will help them keep their beautiful, piped shape while they’re baking.
  • You may find it easiest to peel the potatoes first before cooking them. Be sure to cut the potatoes into even sizes so that they will cook at the same time.

Notes

You and your guests will love these Duchess Potatoes. But, before you fix them up, keep these tips in mind: 

  • Begin preparations on the morning of the day you plan to serve these potatoes. Piping can take longer than you think and requires some elbow grease.
  • Brush the exterior gently with melted butter before baking so the surface can turn brown along the ridges.
  • If you don’t have a piping bag, try adding the potatoes to a Ziploc bag. Cut the corner off and gently squeeze.

Substitutions

  • Dairy-Free – you can use any dairy-free or vegan margarine instead of butter. Use unsweetened almond milk instead of heavy cream. They won’t be as creamy, but they will still be delicious.
  • Cheese– If you use a cheese other than parmesan, choose one that melts evenly. Cheddar, Muenster, Pepper Jack, Fontina or Gruyère would all be good choices.
  • Egg-free– Use panko crumbs instead of eggs to add binding stability to the potatoes.

Duchess Potatoes Recipe

Think of Duchess Potatoes as a fun and exciting way to dress up your favorite mashed potatoes. They look so elegant that your guests will think you spent hours on them.

Prep Time 15 minutes
Cook Time 20 minutes
Total Time 35 minutes

Ingredients

  • 2 1/2 lbs potatoes (around 6-7 medium potatoes)
  • 6 tbsp butter
  • 1 head of garlic
  • 3 - 4 tbsp heavy whipping cream
  • 1/2 cup parmesan cheese, shredded
  • 4 large egg yolks
  • Salt and pepper to taste
  • Parsley, for garnish

Instructions

  1. Begin by bringing the potatoes to a boil in a large, deep pot. Add two tablespoons of salt to the water as it boils. Reduce and allow to cook for about 15 minutes in the water until softened well. Drain, cool, and peel when finished.
  2. Mash the peeled potatoes into a large bowl. Make sure there are no lumps at all. I used a dough blender.
  3. Preheat the oven to 425F. Cover the bottom of a cookie sheet with parchment paper.
  4. While the oven is preheating, mince your garlic and add it with four tablespoons of the butter into a small pan. Cook at a medium heat until the garlic is softened and yellowed.
  5. Remove the pan with the garlic butter from the heat and stir in the heavy whipping cream. Pour into a bowl and set aside.
  6. In the bowl with the mashed potatoes, add in the parmesan and the garlic and butter from its saucepan. Allow the mixture to cool for a few minutes before the next step.
  7. Add in each egg yolk one by one while stirring.
  8. Place the bowl of potatoes into a piping bag with a star tip. Going in a circle all the way up, create the duchess potatoes that are around 2-3 inches wide and tall. Carefully brush with butter.
  9. Baked between 15-20 minutes or until golden brown and slightly crisped. Garnish with parsley and parmesan if desired or your garnish of choice.
