Fish under Marinade (classic recipe)
Fish under marinade is a Soviet-era classic that has earned a permanent spot on family dinner tables and festive spreads alike. Tender pieces of fried sea fish are buried under a glossy, sweet-tangy blanket of slow-stewed onion, carrot, and tomato. Left overnight in the fridge, the fish drinks in the marinade and turns from a simple fry-up into a rich, complex appetizer. Light, healthy, and naturally vegetarian-friendly when the fish is set aside, this dish is also a Lenten favorite across the Russian-speaking world.
Ingredients
Show ingredients
- hake – 2 pcs. (weight about 500 g);
- onion – 2 pcs. (medium);
- carrot – 1 large (or 2 medium);
- tomato paste – 2 tbsp. (or 70 g);
- salt, black pepper – to taste;
- sugar – to taste and desire;
- bay leaf – 2-3 pcs;
- allspice – 4-6 pcs;
- flour – 2-3 tbsp. for breading;
- vegetable oil – for frying.
Preparation
- For cooking, fish like hake, pollock, pelengas, or any sea fish to your taste will work well. Prepare all the ingredients in advance and lay them out on the workspace so the steps flow without interruption.
- Peel the onion and cut it into quarter rings. The shape is important here: quarter rings stay distinct in the marinade and offer a pleasant texture against the soft fish, rather than dissolving into the sauce as small dice would.
- Grate the carrot into strips. You can use a large grater or resort to a grater for Korean-style carrots, but in this case, both the taste and the structure of the vegetable dressing will be different. Choose the cut that suits your texture preference.
- Fill a sauté pan or other thick-bottomed dish with a little vegetable oil. Add the onion and bring it to a golden color, but do not dry it out. When the onion has acquired a nice tint, add the prepared carrot. Immediately add the tomato paste and pour in half a glass of water. Reduce the heat and simmer the vegetable dressing until the carrot is cooked. During the simmering, add salt, pepper, allspice, and bay leaf. If the sauce thickens too much, add a little more water. For flavor balance, a small pinch of sugar may be needed. The vegetables can be cooked very soft or kept slightly al dente, according to family preference.
- Now move on to the fish. The fish must be cleaned, removing all excess: cut off the fins, clean the insides. Do not forget about the black membrane in the belly, which gives bitterness to the product and must be removed. Cut the fish into portioned pieces, mix with salt. Let it sit for about ten minutes and fry on all sides in vegetable oil. Flour is needed for breading.
- Place the golden pieces of fish on paper towels to remove excess oil. Let them cool down a bit for a few minutes. The brief rest also lets the crust set, so the breading does not slide off when the fish is moved to the serving dish.
- After frying, it is easy to remove the backbone from the pieces of fish. It can be done very easily by hand, and the pieces hold their shape and do not crumble. Place the prepared pieces immediately in the dish where we will pour and later serve the fish.
- Now we have two finished components: stewed vegetables in tomato and fried fish. Time to combine them into a single, layered dish that will continue to develop flavor as it rests in the fridge.
- Evenly spread the vegetables over the fish and pour the remaining tomato sauce on top. The sauce will seep through the pieces of fish and add juiciness. Let the dish cool at room temperature, then send it to the refrigerator. Fish under vegetable marinade is best prepared the night before so the fish absorbs the marinade overnight.
- Fish under Marinade (classic recipe) is ready and can be served. We did not stew the fish in the tomato-vegetable dressing, as this would turn it into a different dish — simple fish preserves in tomato. Layering keeps the fish flavor distinct beneath the bright marinade. Serve chilled with rye bread or boiled potatoes alongside.
Tips and Tricks
Tip 1. Choose a firm white fish for best results. Hake, pollock, cod, and pelengas all hold their shape well during frying and stand up to overnight marinating. Avoid delicate fish like sole or flounder — they fall apart under the weight of the marinade. Frozen fillets work fine; just thaw them slowly in the fridge and pat dry before salting and breading.
Tip 2. Make the vegetable marinade slightly more seasoned than tastes right on its own. The fish will dilute the salt and acid as it sits, and a marinade that tastes a touch sharp warm will mellow into perfect balance after a night in the fridge. The same logic applies to the brine in classic pickle soup — under-seasoning is harder to fix later than over-seasoning is to dilute.
Tip 3. Bread the fish lightly. Heavy flour coats turn pasty under the wet marinade. A thin dusting fries up crisp, and once the marinade soaks in, the breading dissolves into a soft, flavorful skin around each piece. Shake off excess flour before the fish hits the pan; clumps in the oil burn and give the marinade a bitter aftertaste.
Tip 4. Layer the dish properly: half the marinade on the bottom, fish in the middle, the rest of the marinade on top. This ensures even flavor penetration and prevents the bottom layer of fish from drying out. Use a non-reactive glass or ceramic dish — metal can pick up the tomato acid and add a metallic taste similar to issues seen with poorly stored tomato paste.
FAQ
How long should fish under marinade rest before serving?
The minimum is two hours in the fridge, but the dish reaches its peak after eight to twelve hours of resting. Many cooks make it in the morning for an evening dinner, or in the evening for the next day. The marinade penetrates the fish slowly, building flavor in layers. Serve the dish chilled or just slightly cool from the fridge for the brightest taste.
Can I bake the fish instead of frying it?
Yes, baking is a healthier option. Place the breaded fish on a parchment-lined sheet, drizzle with a little oil, and bake at 200°C for 15-20 minutes until golden. The texture will be drier than fried fish, but the marinade adds back moisture during the rest. Skip the breading entirely if you want the lightest version — just season the fish and bake it plain before layering.
How long does fish under marinade keep in the fridge?
Properly stored in a covered glass or ceramic container, the dish keeps for three to four days in the refrigerator. The flavors continue to deepen for the first 24 hours, then plateau. After day four the fish texture starts to break down. This dish does not freeze well — the vegetables become watery and the fish texture suffers significantly upon thawing, so plan to enjoy it fresh.
Is this recipe suitable for Lent or vegetarians?
Fish under marinade is a Lenten favorite for those who include fish during the fasting period. For a fully vegetarian version, replace the fish with thick slices of fried eggplant, zucchini, or pan-seared tofu. The vegetable marinade itself is naturally vegan and shines just as brightly over plant proteins as over fish. Serve with bread or boiled grains for a complete meal.
