Pan-seared trout served over rice with a creamy Czech dill sauce (koprova omacka), a classic homestyle pairing.
Koprová omáčka, Czech dill sauce, is a beloved comfort-food staple usually served over hard-boiled eggs or beef, made from a simple roux thickened with milk or cream and loaded with fresh or dried dill. Its tang comes from a splash of vinegar and a pinch of sugar, a balance typical of many Czech cream sauces that lean sweet-and-sour rather than purely rich. Here the sauce is paired with pan-seared trout, a fish commonly caught in Czech rivers and ponds, over a bed of plain buttered rice. Searing the trout skin-side down first and leaving it mostly undisturbed gives a crisp skin that holds up under the creamy sauce rather than disintegrating into it. The dill sauce itself should be smooth and pourable, with a gentle vinegar tang balanced by a touch of sugar — taste as you go, since the ratio varies depending on how sharp your vinegar and how salty your stock are. This makes a homestyle dinner that leans into classic Czech comfort-food flavors rather than typical seafood-forward preparations.
Serves 4
Melt 2 tablespoons butter in a saucepan over medium heat. Whisk in flour and cook 2 minutes, stirring constantly, until pale golden and no longer smells raw.
Gradually whisk in stock, ensuring no lumps form, then bring to a simmer and cook 8-10 minutes until thickened enough to coat a spoon.
Stir in cream, dill, vinegar, sugar, salt and pepper. Simmer 3 minutes more, then taste and adjust the vinegar-to-sugar balance to your liking.
Add vinegar and sugar gradually and taste between additions — the right balance is a gentle tang, not sharp acidity.
Season trout fillets with salt and pepper. Melt a little extra butter in a skillet over medium-high heat and sear skin-side down 4 minutes until crisp, then flip and cook 2 minutes more until just cooked through.
Spoon rice onto plates and top each with a trout fillet.
Ladle the warm dill sauce generously over the trout and rice, and serve immediately.
Use fresh dill rather than dried if possible — dried dill loses much of its bright, grassy aroma and the sauce will taste flatter.
Don't move the trout while it sears skin-side down — let it release naturally from the pan, usually after about 4 minutes, for the crispest skin.
If the sauce is too thin, simmer it a few minutes longer rather than adding more flour, which can make it taste pasty.
Serve the dill sauce over hard-boiled eggs and boiled potatoes instead of trout for the classic Czech vegetarian version.
Swap trout for poached chicken breast for a milder, family-friendly variation.
Add a spoonful of Dijon mustard to the sauce for extra depth, a common home addition.
Refrigerate sauce and fish separately up to 2 days. Reheat the sauce gently over low heat, whisking often, and warm the fish briefly in a low oven to avoid overcooking.
Koprová omáčka is one of the most iconic Czech cream sauces, traditionally served over hard-boiled eggs with boiled potatoes or beef, and remains a staple of home cooking and school cafeterias across the Czech Republic.
Yes, but use about a third of the amount and add it earlier in the simmering process so it has time to rehydrate and release its flavor; fresh dill stirred in at the end will always taste brighter.
Any mild white fish like tilapia or cod works well; adjust searing time based on thickness, aiming for opaque and flaky throughout.
Too much vinegar was added at once. Balance it by stirring in a little more sugar and cream, a small amount at a time, until the tang softens.
