What Do Sardines Taste Like? Canned vs Fresh, and How to Enjoy Them

What do sardines taste like? Rich, oily and savory, with a medium-strong “sea” flavor that is stronger than canned tuna but milder than cured anchovies. Canned sardines are firm, dense and salty with soft, edible bones; fresh sardines are softer, moister and noticeably milder. The closest familiar comparison is a small, oilier mackerel.

If you like canned tuna and want more flavor, start with sardines packed in olive oil, on toast with lemon. If mackerel is too much for you, choose small skinless, boneless sardines and dress them well; if you want no fishiness at all, see our mild fish guide.

Are sardines fishy?

Moderately, and size and freshness matter more than the fish itself. NOAA’s Pacific sardine profile says that “when fresh, small sardines have a delicate flavor,” while larger sardines have a fuller, oilier flavor it compares to anchovies, only milder. NOAA also says to cook fresh sardines within a day of purchase; after that, the oil that makes them taste good starts to make them taste fishy.

Canning concentrates everything. Water-packed sardines taste the fishiest because nothing buffers the flavor; olive oil rounds it off; tomato and mustard sauces cover it.

Do sardines taste like tuna?

No. Canned light tuna in water has 0.96 g of fat per 100 g; sardines in oil have 11.4 g. That fat is the whole difference: tuna is meaty, dry and nearly neutral, while sardines are oily, soft and taste of the sea. Sardines also come with skin and bones (edible, but noticeable); tuna does not.

Neither fish is savory because of glutamate. The Umami Information Center measures free glutamate at 10–20 mg per 100 g in sardine and 1–10 mg in tuna, against 630 mg in cured anchovies. The savoriness in sardines comes from fat, salt and the inosinate in the muscle (280 mg per 100 g by the same source), not from the aged, cheese-like depth of anchovies. For the leaner fish, see what tuna tastes like.

What do sardines taste like from the can? Oil vs water vs tomato

In olive oil: the richest and roundest. The oil absorbs flavor and is worth using on the toast. Best for eating plain.
In water: leaner and cleaner, but the fish flavor stands out more. Rinse, then dress with lemon, olive oil and salt.
In tomato or mustard sauce: the sauce dominates. USDA’s record for Pacific sardines in tomato sauce shows 185 kcal, 10.4 g fat and 240 mg calcium per 100 g, with 1.4 g of EPA and DHA.
Skinless and boneless: milder and smoother, but the bones are where most of the calcium is, so you trade away much of the 382 mg figure above.
Smoked: sweeter and drier, closer to smoked mackerel, and a good base for a smoked fish dip.

Fresh sardines vs canned sardines

They are almost different foods. NOAA sums up the texture in four words: “firm when canned; soft when fresh.” A fresh sardine, grilled whole with salt and lemon, is mild, juicy and flaky, and the skin crisps like a tiny mackerel’s. A canned sardine is compact and salty, built for bread.

In the US, fresh sardines are mostly an import. NOAA reports that the Pacific sardine fishery closed in 2015 and has not reopened, so the fresh fish at the counter is usually Portuguese or Mediterranean. Buy them the day you cook them.

How to make sardines taste good

Four things fix almost any sardine: acid, fat, crunch and aromatics.

Toast: oil-packed sardines on buttered or oiled toast, lemon juice, flaky salt, parsley, black pepper. Add thin red onion or a smear of mustard.
Pasta: mash a tin into warm olive oil with garlic, chili flakes and lemon zest; toss with spaghetti and toasted breadcrumbs. Fennel and raisins make it Sicilian.
Salad: treat them like tuna. Mash with mayo or yogurt, mustard, celery and lemon.
Grill or fry fresh ones: salt, oil, hot grill, three minutes a side; or dredge in seasoned cornmeal and shallow-fry, the way a Florida fish camp (or the fish fry at Fish On Fire) treats small fish.

If the backbone bothers you, split the fish with a fork and lift it out in one piece.

Are sardines healthy, and are they safe to eat?

Yes on both counts. The FDA lists sardines among its “Best Choices,” the group it says can be eaten two to three times a week, including during pregnancy. Sardines are small plankton-eaters that NOAA says usually live no more than five years, which keeps mercury low.

Per 100 g drained, USDA lists 208 calories, 24.6 g protein, 382 mg calcium, 4.8 µg vitamin D, 8.94 µg vitamin B12, 2.92 mg iron and about 1 g of EPA and DHA. Sodium is 307 mg per 100 g in oil; cholesterol is 142 mg, higher than most fish.

Where sardines come from, season and sustainability

“Sardine” is a market name, not one species, and three fish fill the tins sold in the US:

Pacific sardine (Sardinops sagax), the West Coast species NOAA profiles: it schools from Southeast Alaska to Baja California and grows to more than 12 inches. The 2025 assessment found the stock overfished, directed fishing has been closed since 2015, and the rebuilding target is 2035.
European pilchard (Sardina pilchardus), the fish in most Portuguese, Spanish and Moroccan olive-oil tins. Seafood Watch’s February 2024 list rates Moroccan purse-seine sardines yellow (“Good Alternative”) and the Mediterranean and Iberian-coast fisheries red (“Avoid”).
Small Atlantic herring (Clupea harengus), canned as sardines in Canada and Maine; USDA’s “sardine, Atlantic, canned in oil” record is literally this species.

MSC-certified sardines from Australia and Mexico’s Gulf of California carry Seafood Watch’s top “certified” (blue) rating.

Sardines vs anchovies

Sardines are a fish you eat; anchovies are mostly a seasoning. Sardines grow past 12 inches, northern anchovies to about 7; sardines in oil carry 307 mg sodium per 100 g, cured anchovies 3,670 mg; and anchovies have about 30 times the free glutamate. Full comparison in what anchovies taste like. For the fresh-fish relatives, see mackerel and Florida’s Spanish mackerel; for the richest fish of all, eel.

Bottom line

Sardines taste like a richer, oilier, saltier version of mackerel, firm from the can and soft from the grill. Buy them in olive oil, add lemon and something crunchy, and they go from “fishy” to one of the best cheap proteins in the store.
