📝 About This Recipe
A beloved Danish tradition, Skidne Æg (literally 'Dirty Eggs') is a comforting masterpiece of soft-boiled eggs draped in a rich, velvety mustard cream sauce. Traditionally served on 'Dirty Saturday' during Easter, this dish balances the sharp tang of Dijon and grainy mustards with the earthy depth of dark rye bread. It is a sophisticated yet rustic example of Smørrebrød that transforms simple pantry staples into a decadent, soul-warming meal.
🥗 Ingredients
The Eggs
- 8 pieces Large Eggs (organic or free-range preferred)
The Mustard Sauce (Sennepssovs)
- 3 tablespoons Unsalted Butter (high quality)
- 3 tablespoons All-purpose Flour
- 2 cups Whole Milk (warmed slightly)
- 2 tablespoons Dijon Mustard (for sharp heat)
- 2 tablespoons Wholegrain Mustard (for texture and depth)
- 1/4 cup Heavy Cream (for extra silkiness)
- 1 teaspoon Sugar (to balance the acidity)
- 1/2 teaspoon Sea Salt (adjust to taste)
- 1/4 teaspoon White Pepper (ground)
- 1 teaspoon Lemon Juice (freshly squeezed)
The Foundation and Garnish
- 4 slices Danish Rye Bread (Rugbrød) (dense and dark)
- 1 bunch Fresh Chives (finely snipped)
- 1 punnet Fresh Cress (for a peppery bite)

👨🍳 Instructions
-
1
Bring a large pot of water to a gentle boil. Carefully lower the eggs into the water using a slotted spoon.
-
2
Boil the eggs for exactly 7 to 8 minutes. This ensures a 'smilende' (smiling) egg—where the white is set but the yolk remains soft and jammy.
-
3
Immediately transfer the eggs to a bowl filled with ice water to stop the cooking process. Let them sit for at least 5 minutes before peeling.
-
4
While the eggs cool, start the roux for the sauce. In a medium saucepan, melt the butter over medium heat until it begins to foam.
-
5
Whisk in the flour to form a smooth paste. Cook for 1-2 minutes, stirring constantly, to remove the raw flour taste without browning the butter.
-
6
Gradually pour in the milk in a thin stream, whisking vigorously to prevent lumps. Continue until all the milk is incorporated and the sauce is smooth.
-
7
Reduce the heat to low and simmer the sauce for 5-7 minutes, stirring occasionally, until it thickens enough to coat the back of a spoon.
-
8
Stir in the Dijon mustard, wholegrain mustard, sugar, and heavy cream. The sauce should turn a beautiful pale yellow with visible mustard seeds.
-
9
Season with salt, white pepper, and a squeeze of lemon juice. Taste and adjust the mustard levels if you prefer a sharper kick.
-
10
Peel the cooled eggs carefully and slice them in half lengthwise.
-
11
Lightly butter your slices of dark rye bread. Place one or two slices on each plate.
-
12
Arrange four egg halves on each slice of bread, yolk side up.
-
13
Generously spoon the warm mustard sauce over the eggs, allowing it to pool slightly onto the bread.
-
14
Garnish heavily with snipped chives, fresh cress, and radish slices for a pop of color and crunch.
-
15
Serve immediately while the sauce is warm and the eggs are perfectly tender.
💡 Chef's Tips
For the most authentic experience, use a dense, seeded Danish Rugbrød; if unavailable, a heavy German pumpernickel is the best substitute. To peel eggs perfectly, crack the shells all over and peel them under a thin stream of cool running water. Don't let the sauce boil once the mustard is added, as high heat can cause the mustard to lose its characteristic pungency and become bitter. If the sauce becomes too thick, simply whisk in an extra tablespoon of milk or cream to loosen it back to a pourable consistency. Always use white pepper instead of black to maintain the clean, creamy aesthetic of the pale yellow sauce.
🍽️ Serving Suggestions
Pair with a cold Danish Pilsner or a crisp Lager to cut through the richness of the cream sauce. A chilled glass of Akvavit (Aquavit) is the traditional spirit pairing for a festive Easter lunch. Serve alongside a simple side of pickled herring or a fresh cucumber salad for a complete Smørrebrød spread. Add crispy bacon bits on top if you desire a smoky, salty contrast to the creamy eggs. For a lighter brunch, serve the eggs and sauce over toasted sourdough instead of rye.
