Ingredients
- 5 oz medium waxy potatoes (such as Yukon Gold)
- 2 tablespoons unsalted butter
- ½ medium yellow onion
- 3 tablespoons whole grain German mustard
- ½ cup full-fat sour cream
- ½ cup vegetable broth
- 4 whole large eggs
- ½ teaspoon sea salt
- ¼ teaspoon freshly cracked black pepper
- 1 tablespoon fresh dill (optional garnish)
Instructions
- 1
Cut 5 ounces of medium waxy potatoes into 1/2-inch cubes — you want them uniform so they cook evenly. Place them in a small pot, cover with cold salted water, and bring to a boil over medium-high heat. Cook until just tender when pierced with a fork, about 8-10 minutes. You're looking for them to hold their shape but have no resistance at the center.

While the potatoes cook, peel and finely dice half a medium yellow onion into 1/4-inch pieces — this small amount will perfume the sauce without overpowering it.
- 3
In a small bowl, whisk together 3 tablespoons of whole grain German mustard, 0.5 cup of full-fat sour cream, and 0.5 cup of vegetable broth until completely smooth. Season with 0.5 teaspoon of sea salt and 0.25 teaspoon of freshly cracked black pepper. Set aside.

Drain the cooked potatoes in a colander and set aside. Return the empty pot to medium heat and add 2 tablespoons of unsalted butter. Once melted and foaming, add the diced onion and sauté until softened and translucent, about 2-3 minutes. You should smell the onion's sweetness develop.
- 5
Pour the mustard-sour cream mixture into the pot with the softened onion, stirring constantly to combine. Heat through over medium, stirring occasionally, until the sauce is steaming but not boiling — about 2 minutes. The sauce should smell pungent and rich.

Gently add the drained potatoes to the sauce and stir to coat. Let them warm in the sauce for 1 minute, then carefully create 4 shallow wells in the potato mixture using the back of a spoon — these are where your eggs will nestle.
- 7
Crack 4 large eggs directly into each well, one at a time. Reduce the heat to medium-low and cover the pot with a lid. Cook until the egg whites are set but the yolks remain soft and runny, about 4-5 minutes. Check at 4 minutes by gently tilting the pot — the whites should be opaque and firm, while the yolk should jiggle slightly when you gently shake the pot.
- 8
Divide the potato and mustard sauce mixture between two shallow bowls, making sure each gets 2 eggs with some sauce. Spoon any extra sauce from the pot over the eggs. If using fresh dill, tear 1 tablespoon of leaves and scatter over the top. Serve immediately while the eggs are still warm and the yolks are runny — the runny yolk will create its own sauce when broken into the mustard cream.
