Recipe for Poached Fish with Mustard Sauce – Oma's Fisch mit Sosse

Oma Gerhild

by: Gerhild Fulson  / Oma Gerhild shares German recipes rooted in family tradition.

Need a recipe for poached fish, aka Pochierter Fisch? Here's one with a mustard sauce that's one of my quick meals recipes.

Poaching keeps the fish moist and provides for the base for the sauce. Instead of using flour or cornstarch to thicken the sauce, the poaching liquid is reduced. The resulting sauce is thickened by stirring in some butter at the end.

The result? Delicious and light-tasting!

This dish tastes great when served with boiled potatoes and a salad.

Use any firm, mild white fish, such as cod, haddock, or sole for this very traditional German dish.

Serving fish with mustard is very common in Germany. For another easy fish dish that uses mustard, try my Dijon salmon.
