The Crispy Fish Burger is a delicious alternative for those looking for variety and not always wanting to eat meat. It consists of a crispy breaded fish fillet, often complemented with refreshing ingredients like iceberg lettuce, tomatoes, and onions. A creamy sauce, often made with mayonnaise and a hint of lemon, gives the burger a special touch. This burger is not only popular in fast-food restaurants but is also easy to prepare at home. The Crispy Fish Burger can also be prepared with different types of fish to achieve different flavors.
TIP:
A sweet and spicy honey mustard sauce is a perfect accompaniment. Preparation is simple and straightforward. Mix honey and mustard in a 1:1 ratio until you get a smooth sauce. You can also add spices or ingredients to vary the flavor, such as vinegar, mayonnaise, or dill.

You really have to like fish burgers to become a fan . This burger, however, is significantly more upscale than the "old favorite" – Prime Recipes

Crispy Fish Burger
For the burger
2 burger buns
300g cod
150g panko breadcrumbs (for marinating)
50g flour (for marinating)
1 egg (for marinating)
2 slices of cheddar cheese
1 onion
2 Lollo Bianco lettuce leaves
1 tbsp salt
2 L oil for frying
For the remoulade sauce
50g Greek yogurt
50g mayonnaise
20g capers
2 gherkins
1/4 bunch of chives
1/4 bunch of parsley
1/4 bunch of dill
1 tsp mustard
2 tsp sugar
1 tbsp olive oil
Salt & pepper
7-step preparation
1. Prepare the remoulade sauce
Finely chop the capers and gherkins. Wash the herbs, shake dry, and finely chop them as well. Mix Greek yogurt and mayonnaise in a bowl. Stir in mustard, olive oil, sugar, salt, and pepper. Finally, add the chopped ingredients and mix thoroughly. Chill the finished sauce.
2. Prepare the onions
Peel the onion and slice it into thick rings. Set aside.
3. Bread the fish
Prepare three bowls: – 1 with flour, – 1 with beaten egg (whipped until frothy), – 1 with panko breadcrumbs and a little salt. Pat the cod dry, first coat it in flour, then dip it in the egg, drain well, and coat thoroughly in the panko until all sides are well coated.
4. Heat the oil
Heat enough oil in a deep pot to approximately 175–180°C.
Caution: Never leave the fish unattended and ensure that no water gets into the hot oil!
5. Fry the fish
Carefully add the breaded cod to the hot oil and fry for 4–7 minutes until golden brown and crispy. Drain on paper towels and immediately top with a slice of cheese to melt slightly.
6. Toast the buns
Cut the burger buns in half, brush the cut sides with butter, and toast cut-side down in a pan for about 30 seconds until lightly browned.
7. Assemble the burgers
Brush the toasted bun halves with the remoulade sauce. Then top the burger with lettuce leaves, the fried cod with cheese, and the onion rings. Place the top bun half on top and serve immediately.
💡 Save calories –
Total savings potential: 👉 Up to 200–300 kcal per serving if you:
Reduce panko to 75g – some of it usually goes unused anyway
Replace frying oil with baking or air fryer – saves a lot of fat
Use only 1 slice of cheese instead of 2 or choose a light cheese
Halve the mayonnaise in the sauce or replace it with low-fat yogurt
Omit olive oil from the sauce (yogurt still makes it creamy)
Replace or omit sugar with calorie-free alternatives (little impact on flavor)
👉 This keeps the burger crispy, flavorful, and fresh, but significantly lighter and more balanced in calories.
