What Is Bluefish and How Can I Use It?
Here's everything worth knowing about bluefish and how to pick it, what it is, how to store it, and what to use instead, plus 10 recipes to cook tonight.
Key Points
- Oily, full-flavored Atlantic fish with dark, meaty flesh that suits the grill and broiler.
- Acid and bold seasoning balance its richness; lemon, tomato, and fennel are naturals.
- Cut out the dark lateral muscle if you find the flavor too assertive.
- Highly perishable: cook within a day or two, freeze no longer than two months.
- Best swaps are Spanish or king mackerel; skip lean fish like cod or tilapia.
What is bluefish?
Bluefish is a fast, oily saltwater fish caught along the Atlantic coast. Anglers and cooks reach for it when they want real flavor.
The flesh runs darker and richer than most white fish, with a meaty texture and a pronounced taste that turns mild and almost sweet when the fish is very fresh. That richness is the whole story with bluefish, and it comes from a high oil content.
The oil makes the fish a natural for the grill but also means it does not keep well. Freshness matters more here than with cod or haddock.
Cooking With Bluefish
Bluefish takes well to high, dry heat. Broiling and grilling are the classic moves because the oil bastes the flesh and the skin crisps instead of going rubbery. Maple Basted Broiled Bluefish glazes the fillet under the broiler so the sugars caramelize against the dark meat.
Bold flavors are your friends.
Acid in particular cuts the richness, which is why Blue Fish with Oranges & Oregano Flowers and Bluefish with Fennel & Tomato Sauce both work. The tomato, citrus, and fennel all push back against the oil.
A whole fillet cooks in 8 to 12 minutes, depending on thickness. Pull it the moment the flesh turns opaque and flakes, because bluefish dries out fast once it is past done.
If the flavor is too strong for you, cut away the darker red lateral muscle down the fillet, which carries most of the assertive taste.
Smoked bluefish is a New England tradition worth knowing. The oily flesh takes smoke beautifully and flakes into chowders and spreads, as in Peter's Smoked Bluefish Chowder.
What to Pair It With
Bright, herbal, acidic flavors balance bluefish best: lemon, tomato, capers, mustard, fennel, and fresh herbs like dill and oregano. A simple mock tartar sauce, as in Baked Breaded Bluefish with Mock Tartar Sauce, gives the richness something tangy to lean on.
The common mistake is treating bluefish like a delicate white fish and seasoning it timidly. Underseason it and the oiliness reads as fishy rather than rich.
The other mistake is buying it a day too late. Off bluefish develops a strong, almost ammoniated edge that no amount of lemon will fix.
Substitutes
If you cannot find bluefish, reach for another oily, full-flavored fish. Spanish mackerel is the closest match in both fat and taste, and king mackerel works the same way. Atlantic mackerel is smaller and a touch milder but cooks the same.
For something gentler, fresh sardines or whole trout will stand in, though both are leaner and you may want to add a little oil or butter. Skip cod or tilapia: too lean and bland to behave like bluefish under the broiler.
Buying and Storing Bluefish
Buy bluefish the day you plan to cook it, or as close to that as you can manage. Look for firm, shiny flesh with a clean sea smell and bright gray-blue skin.
A sour or sharply fishy odor means it is past its prime; whole fish should have clear eyes and red gills.
Because of its high oil content, bluefish spoils faster than lean fish. Keep it on ice or in the coldest part of the fridge and cook it within a day, two at the outside.
For longer storage, freeze it well wrapped and use it within two months. The same oils that make the fish so good also go rancid in the freezer faster than leaner fish would.
