How Long to Cook Herring
Atlantic herring (Clupea harengus) is one of the most abundant and historically important fish in the world — a nutritional cornerstone of Northern European diets for thousands of years. Supremely rich in omega-3 fatty acids, herring has an assertive, savory flavor that lends itself to every form of preservation and cooking. Fresh herring briefly simmered is prized in Scandinavia and the Netherlands; the majority of global production is pickled, salted, or smoked.
- Very oily — simmer, never boil
- Slight acid in cooking water helps flavor

Cooking temperature: liquid at 82 to 90°C / 180 to 194°F. Start timing once the water reaches a gentle simmer.
Always add a splash of white wine vinegar to the cooking liquid. Herring is done when the flesh is opaque throughout and pulls away from the backbone cleanly.
Preparation
How to Prepare Herring Before Cooking
Herring has small, fine scales that come off easily. Scale from tail to head with a knife or scaler. Gut through the belly and remove the gills. Rinse thoroughly under cold running water.
For fillets: make a cut along the backbone from just behind the head to the tail, and lift off each fillet. Herring fillets contain many fine pin bones distributed throughout the flesh. Run your finger along the centerline to locate them and remove with tweezers, or leave them — they are edible and soften significantly during cooking.
The key preparation is the cooking liquid. Add white wine vinegar (1 to 2 tablespoons per litre), onion, bay leaf, allspice, and peppercorns. The acidity directly counteracts herring’s rich oiliness and is not optional for best results.
Method
How to Cook Herring Step by Step
- Scale, gut, remove gills, and rinse herring thoroughly.
- Prepare cooking liquid: water, white wine vinegar, onion, bay leaf, allspice, peppercorns.
- Place herring in cold liquid and bring to a gentle simmer.
- Whole herring (150 to 250 g): simmer 12 to 18 minutes. Fillets: simmer 8 to 12 minutes.
- Check doneness: flesh is opaque throughout and pulls from backbone cleanly.
- Remove carefully and drain. Serve immediately.
- Reserve cooled cooking liquid enriched with extra onion and vinegar as a base for herring in aspic or pickled herring broth.

Herring Cooking Time Chart
| Form | Method | Time | Notes |
|---|---|---|---|
| Whole (150–250 g) | Gentle simmer | 12 to 18 minutes | Opaque throughout; pulls from backbone. |
| Fillets | Gentle simmer | 8 to 12 minutes | Thin fillets cook fast; watch closely. |
| Whole (150–250 g) | Rolling boil | 9 to 13 minutes | Not recommended — strong flavor, dry flesh. |
| Fillets | Rolling boil | 6 to 9 minutes | Gentle simmer strongly preferred for oily fish. |
Doneness
How to Know When Herring Is Done
Herring is done when the flesh is completely opaque throughout — no translucency remaining near the spine — and pulls away from the backbone cleanly when pressed with a fork. The flesh should be tender and slightly firm, not falling apart. For fillets, check the thickest point: it should separate into soft flakes.
Because herring is an oily fish, it remains moist even when slightly over the minimum time. However, boiling too hard degrades the oils and produces strong, unpleasant flavors — always simmer gently.
Safety note: fish is safe to eat when it reaches an internal temperature of 63°C / 145°F and the flesh is fully opaque throughout. Fresh herring must be thoroughly cooked before eating.
Seasoning
Best Seasonings for Herring
Court-bouillon with white wine vinegar, onion, bay leaf, allspice, and peppercorns is the essential preparation. Dill, mustard, and cream-based sauces complement the richness. Scandinavian tradition serves with sour cream, dill, and pickled cucumber. Dutch tradition celebrates raw herring (maatjes) with onion and pickles — a preparation that requires no cooking. Mustard sauce is universally flattering with cooked herring.
Avoid this
Common Mistakes
- Boiling hard — makes the flesh strong-tasting and dry despite the oil content.
- Not adding acid to the cooking water — results in a heavy, overly fishy flavor.
- Over-seasoning an already assertive fish.
- Serving without an acid accompaniment — mustard, vinegar, pickles, or lemon are essential.
- Using stale fish — herring deteriorates quickly; buy the day you plan to cook it.
Serving
What to Serve With Cooked Herring
With dill cream, mustard sauce, pickled vegetables, and dark rye bread. Cold poached herring with sour cream and onion is a classic Northern European preparation. The cooled cooking liquid, enriched with more onion and vinegar, can be used as a base for herring in aspic — a traditional Polish and Scandinavian dish. Boiled potatoes and pickled cucumber are the standard accompaniments.

Leftovers
Storing and Reheating Cooked Herring
Cooked herring keeps refrigerated for 1 to 2 days. It is better served cold than reheated — reheating intensifies the fishy flavor. Cold poached herring with sour cream or mustard dressing is excellent. The cooking liquid, cooled and enriched, can be used as a pickling brine for leftovers.

Useful Tools for Cooking Herring
- Fish scaler or knifeFor the fine scales — work over the sink or in a bowl of water.
- Kitchen tweezersFor removing pin bones from fillets, or simply leave them as they soften with cooking.
- Wide shallow panAllows whole herring to lie flat and cook evenly.
- Fine strainerFor straining and reserving the flavorful cooking liquid for sauces or aspic.
- Slotted spoonFor lifting delicate whole fish or fillets without breaking them.
Questions
FAQ
How long does fresh herring take to cook?
Whole fresh herring (150 to 250 g) takes 12 to 18 minutes at a gentle simmer. Herring fillets take 8 to 12 minutes. Test by checking that the flesh is fully opaque throughout and separates from the backbone without resistance. Always add acid (vinegar or white wine) to the cooking liquid.
Is fresh herring always boiled?
No. Herring is most commonly consumed pickled, salted, smoked, or grilled rather than boiled. Fresh herring simmered in court-bouillon is a traditional Northern European preparation, particularly in Scandinavia and the Netherlands. The various cured and pickled preparations are far more common globally — boiling fresh herring is a regional specialty.
How do you deal with herring’s bones?
Herring has a central spine and rib bones plus many small pin bones distributed in the fillet. After filleting, run your finger along the centerline to locate pin bones and remove with tweezers if desired. For whole cooked herring, remove bones at the table. The small bones soften considerably with cooking and are edible — many people simply eat them.
Why is freshness so important for herring?
Herring has a very high oil content and its oils begin to oxidize and degrade quickly after the fish dies. Stale herring has a very strong, unpleasant, rancid-tasting flavor. Always buy herring the day you plan to cook it; look for bright eyes, firm flesh, and a fresh sea smell rather than a strong fishy odor.
