What Are Sardines and How Can I Use Them?
Wondering what to do with sardines? This guide covers how to pick them, cook them, store them, and swap them, plus 9 recipes to put them to work.
Key Points
- Small, oily herring-family fish; canned for the pantry or grilled fresh, bones soft enough to eat.
- Rich and briny: brighten with lemon, vinegar, or a sharp aioli to cut the richness.
- Eat canned straight from the tin on toast, in sandwiches, or blended into a pate.
- Grill fresh sardines 2 to 3 minutes a side; a minute too long turns them dry.
- Brisling, sprats, and canned mackerel are the closest swaps; anchovies are saltier, use less.
What are sardines?
Sardines are small, oily fish in the herring family, sold most often canned but also wonderful fresh off the grill. The name covers several species of young, small fish packed whole or filleted, soft enough that the tiny bones cook down and become edible, calcium and all.
The flavor is rich and briny, far bolder than a flaky white fish. That intensity is exactly why people love them or keep their distance, and a good squeeze of lemon brings the whole thing into balance.
How to Use Sardines
Canned sardines are ready to eat straight from the tin. They are one of the fastest proteins in the pantry.
Mash them onto buttered toast, fold them into a salad, or build them into a quick lunch.
The sandwich is their natural home. Open Face Sardine Sandwiches with Quick Aioli pile the fish on bread with a garlicky mayonnaise, the Bumstead Sandwich stacks them tall, and Sardine Sandwich Butter blends them with butter into a spread for crackers or toast.
They also blend smooth. Norwegian Sardine Pate turns the canned fish into a soft, spreadable starter, while Sloppy Sardines cooks them down into a saucy, casual supper.
Fresh sardines are a different pleasure. Score the sides and grill them over high heat for 2 to 3 minutes a side until the skin blisters, or roll them into pasta, as in Perciatelli with Fresh Sardines, where the oily fish melts into the sauce.
Pairing and Common Mistakes
Sardines want acid and brightness to cut their richness. Lemon, vinegar, tomato, capers, red onion, parsley, chili: all of them pull their weight, and a sharp mustard or aioli gives canned sardines a tangy lift.
The most common mistake is serving them cold and plain and expecting them to win over a skeptic. Warm them through and dress them with lemon on good toast, and the same fish convinces far more people.
The other slip is overcooking fresh sardines. They are thin and oily, so a minute too long turns them dry and chalky; pull them the moment the flesh turns opaque.
Substitutes
Reach for another small, oily fish. Brisling and sprats are nearly the same thing under different names, and canned mackerel brings the same richness in a slightly larger, milder package.
Anchovies are far saltier and more intense, so use them where you want a savory hit rather than a main event, and cut the quantity.
For a milder swap on toast, canned tuna works, though it lacks the briny depth and the soft, edible bones.
Buying and Storing Sardines
Canned sardines keep for years unopened in a cool, dark cupboard. Many fans say they improve with a little age in the tin. Once opened, move any leftovers to a covered container and refrigerate, then use within two days.
Sardines packed in olive oil tend to taste richer and hold up better than those in water; the oil also makes a fine base for a dressing once the fish is gone.
Fresh sardines are intensely perishable because of their oil content. Buy them shiny and firm with a clean sea smell, keep them on ice, and cook them the same day.
They turn fast, often the day after they are caught, so freshness is not negotiable.
