Finnish Egg Sauce is a comforting white sauce with hard-boiled eggs, fresh dill, chives, and a splash of lemon juice. It’s the perfect accompaniment to boiled or breaded fish, smoked fish, new potatoes, and seasonal vegetables. This classic Finnish sauce is easy to make and brings fresh Nordic flavors to everyday meals.
Fresh Herbs Make the Difference
This is the version of Finnish Egg Sauce I grew up with. Fresh dill, chives, and a splash of lemon juice give the sauce a lighter, fresher flavor while still keeping it wonderfully creamy.
Some recipes use only milk, instead of combining milk, cream, and stock. In many recipes, there is no lemon juice either. I like the combination of dill and chives because they complement the eggs and add plenty of fresh flavor. The lemon juice balances the richness of the sauce without making it taste lemony.
Finnish Egg Sauce is traditionally served with fish, but it’s just as delicious with boiled new potatoes and seasonal vegetables. It’s a simple, comforting sauce that lets the flavors of the main ingredients shine.
A Creamy Sauce with Fresh Nordic Flavors
This recipe uses simple, everyday ingredients and comes together in about 25 minutes.
The creamy white sauce is made with whole milk, a little cream, and a classic butter-and-flour roux. Chopped hard-boiled eggs make the sauce hearty, while fresh dill and chives add plenty of flavor and color. A splash of lemon juice brings everything together and gives the sauce a fresh finish.
It’s a versatile recipe that’s easy enough for a weeknight dinner but also perfect for serving as part of a traditional Finnish meal.
How to serve Finnish Egg Sauce
Finnish Egg Sauce is traditionally served with boiled fish and potatoes, but there are many delicious ways to enjoy it.
I often serve it with breaded whitefish fillets, boiled new potatoes, yellow beans, and carrots. It also pairs beautifully with smoked fish or simply spooned over gently cooked white fish. The creamy sauce complements delicate fish without masking its flavor.
Whether you’re preparing a family dinner or a summer meal with fresh new potatoes, this sauce is a classic choice that never goes out of style.
Tips for the Best Egg Sauce
Whisk the milk into the roux a little at a time to keep the sauce perfectly smooth. Let it simmer gently for about 10 minutes so the flour cooks through and the sauce develops a silky texture.
Once you’ve stirred in the chopped eggs, the sauce will thicken a little more. If needed, simply add a splash of vegetable or fish stock until it reaches your preferred consistency.
Fresh dill and chives give the best flavor, but frozen herbs work well when fresh ones aren’t available.

Leftovers can be gently reheated over low heat. Add a splash of milk if needed to loosen the sauce. The sauce is very delicious with boiled vegetables too.
