It has a loyal following that spikes every spring, and at 380 calories it is one of the lighter sandwiches you can order. Here is the 2026 price and the full nutrition picture.

What is in a Filet-O-Fish

A crispy battered fish fillet made from wild-caught Alaska pollock, tartar sauce, and half a slice of American cheese on a steamed bun. The steamed bun is the detail that defines the sandwich: soft all the way through, no toast, no crunch, which lets the crispy fillet and creamy tartar sauce do all the textural work. The half slice of cheese is the original 1962 build, and McDonald’s has never changed it.

Filet-O-Fish nutrition facts

Full nutrition breakdown for one Filet-O-Fish, based on McDonald’s official US nutrition data.

Nutrient	Amount per Filet-O-Fish
Calories	380
Total fat	19g
Total carbohydrates	38g
Protein	16g
Sodium	580mg

For a fried sandwich the numbers are friendly: 380 calories, moderate fat, and sodium at 580 mg, which is lower than any of the beef burgers. The 16 grams of protein make it reasonably satisfying, though it will not fill you up like a Quarter Pounder.

Allergens

The Filet-O-Fish contains egg, fish, milk, soy, and wheat. The fish is the fillet itself, the egg comes from the tartar sauce, the milk and soy from the cheese and bun ingredients, and the wheat from the bun and batter. The bun may also contain sesame depending on the supplier. With fish and egg both in play, this is one of the more allergen-heavy items on the menu, so check the current guide at your restaurant if you have severe allergies.

How to customize your Filet-O-Fish

• Full slice of cheese instead of half: the most common request, usually free or a tiny upcharge.
• Extra tartar sauce: free at most locations and the easiest way to improve the sandwich.
• Double Filet-O-Fish: two fillets. It exists on request and it is excellent.
• Add lettuce or tomato: available where the restaurant stocks them for other sandwiches.
• No cheese: an option, though the cheese is load-bearing for the classic flavor.

Is the Filet-O-Fish available all day

It is on the regular lunch and dinner menu, typically starting at 10:30 AM on weekdays and 11:00 AM on weekends, though exact times vary by location. Demand peaks during the spring season, when some locations run two-for deals, so watch the app around that time.
