What Is Calamari?

Is calamari squid or octopus?

Calamari is always squid, never octopus. The two are often confused because both are cephalopods with tentacles, but they're different animals. Squid (calamari) has a long tube-shaped body, ten arms, and a thin internal "pen" instead of a shell. Octopus has a rounder body, eight arms, and no internal shell at all. Squid is smaller, milder in flavor, and cooks tender faster; octopus is meatier, denser, and usually needs longer, slower cooking.

What calamari tastes like

• Taste: mild and slightly sweet, not strongly "fishy." It mostly takes on the flavor of how it's seasoned and cooked.
• Texture: tender and a little springy when cooked correctly; rubbery and chewy if overcooked.
• Appearance: the classic dish is golden-fried rings, often served with lemon and a dipping sauce like marinara or aioli.

How it's cooked

Besides frying, calamari is also grilled, sautéed, stuffed, or added to pasta, salads, and seafood stews. The cooking rule is fast and hot, or low and slow — anything in between (a few minutes in a warm pan, for example) makes it tough and chewy, which is the most common mistake home cooks make with it.

Is calamari healthy?

Squid itself is lean and high in protein, with relatively few calories before it's cooked. A 3-ounce (85 g) serving of plain squid has roughly 15 g of protein and under 100 calories, but it's also naturally high in cholesterol for its size. The popular fried version adds significant calories and fat from the breading and frying oil, so a grilled or sautéed serving is the lighter option if that matters to you.

Halal and dietary notes

Squid is seafood, and most Islamic dietary authorities classify all seafood as halal, which is why calamari is widely served and eaten in Muslim-majority countries and by observant Muslims — though some schools of thought differ on non-fish seafood, so if it matters to you, check with your own source of religious guidance rather than a general answer.

Why fast-hot or low-slow actually works: squid's proteins tighten and squeeze out moisture almost immediately when heated, which is why a quick, high-heat sear (or deep-fry) locks in tenderness before that toughening fully sets in. Cooking low and slow instead gives the connective tissue time to break down again after that initial tightening, which is why braised or stewed squid can also turn out tender — it's the in-between zone, a few minutes in a warm pan, that catches it mid-toughening with no time to soften back.

Buying fresh vs frozen: frozen squid (common at most grocery stores) cooks just as well as fresh once thawed, and is often fresher in practice since it's typically frozen at sea shortly after catch — fresh squid should smell like the ocean, not fishy or ammonia-like, which is a sign it's past its best.
