How to Make Duchess Potatoes
Peel + Prep the Potatoes
Before anything prep those potatoes. Rinse and peel the potatoes before chopping them into quarters.
We peel the potatoes for this recipe so that when you pipe the potatoes into mounds, the peels won’t get stuck in the pipping bag.
Add the potatoes to a large pot of salted water and bring to a boil. Let the potatoes boil for 15-20 minutes until they are fork tender.
Strain the potatoes and place them in a separate large bowl.
Mash + Pipe
Mash the potatoes with a potato masher until there are no lumps. We suggest hand mashing so that you don’t overwork the potato. It can become too gluey making it hard to pipe and hold its form while baking.
After you have mashed the taters, add three tablespoons of the butter to the potatoes and stir. Then, add one egg yolk at a time until they are combined.
Spoon the mashed potatoes into a pipping bag and pipe them into 12 mounds on a baking sheet. Brush the mounds with the remaining melted butter.
Place the duchess potatoes into the oven and bake them for 18-20 minutes or until set and golden brown.
