McDonald's Filet-O-Fish Complete Information

A McDonald's Filet-O-Fish costs $6.59 and carries 380 calories, which makes it the lightest sandwich on the whole menu. Wild caught Alaska Pollock in a crisp coating, half a slice of American cheese and tartar sauce on a steamed bun.

The Filet-O-Fish has been on the menu since 1962, four years longer than the Big Mac, and it still arrives built the same way. Two details usually surprise people: the bun is steamed rather than toasted, which is why it is soft rather than crisp, and the cheese is deliberately half a slice, so it seasons the fish instead of covering it. At 380 calories with 16g of protein it undercuts every chicken sandwich and every burger except the plain Hamburger. Pair it with Small French Fries, or look at the McCrispy if you want the same format with chicken instead.

How to Make a Filet-O-Fish at Home?

The Filet-O-Fish is unusual to reproduce because two of its three defining features are things most home cooks would call mistakes: a steamed bun and half a slice of cheese. Do both anyway. That is what makes it taste like the $6.59 original rather than a generic fish sandwich.

Tips

  • Steam the bun, never toast it. A crisp bun makes it a different sandwich entirely.
  • Half a slice of cheese is not a saving, it is the recipe. A full slice buries the fish.
  • The cheese goes under the hot fillet so the fish melts it. On top it stays cold.

Variations

  • Add a second half slice of cheese for the Double Filet-O-Fish some markets sell.
  • Use cod instead of Pollock for a firmer, slightly sweeter fillet.
  • Add a squeeze of lemon to the tartar for a sharper sauce than the original.

Serve straight away with fries. A restaurant Filet-O-Fish is $6.59, and the homemade version wins on the fish being fried to order rather than held.

Pairs Well Together

Perfect Combination

Small French Fries is the side a Filet-O-Fish is built around, and the pair is what a meal bundles anyway.

Filet-O-Fish Questions

How much is a Filet-O-Fish at McDonald's?

A Filet-O-Fish is $6.59 at a typical US restaurant, a median from live restaurant listings with the range shown under the price above. Prices are set per franchise, so the figure moves between locations.

What fish is in a Filet-O-Fish?

Wild caught Alaska Pollock, sustainably sourced and certified. It is the same fish used in most fish and chips, mild and white rather than oily. The full published ingredient statement is in the recipe section on this page.

How many calories in a Filet-O-Fish?

380 calories with 16g of protein, which makes it the lightest sandwich on the entire McDonald's menu. Only the plain Hamburger at 250 calories comes in lower among the mains.

Why does the Filet-O-Fish only have half a slice of cheese?

By design, since 1962. Half a slice seasons the fish without burying it, and a full slice would overwhelm a mild Pollock fillet. It is one of the few deliberate half portions anywhere in fast food.

Why is the Filet-O-Fish bun soft?

It is steamed rather than toasted, which is unique to this sandwich on the McDonald’s menu. The softness is intentional and matches the texture of the fish; a toasted bun would fight it.
