I know they will scare you with the mercury and antibiotics from the farmed fish! Well, this can be a problem. But remember, frozen fish usually comes directly from fishing boats. This is the best way to continue having fish and its health benefits in any part of the globe.

How the original fish burgers are made?

Well, suspicious types of fish flesh can be the main ingredient. They then add wheat or corn flour to get the volume and texture. Then, the in who knows what oil. Even if you use olive oil, frying starch can be quite toxic. Now, if we talk about industrially prepared ready products, you know those that you just nuke and eat, those are not even food! Just look at the label. The list of stabilisers, additives, corn starch, modified or not… You simply should not ever grab such a product. Regardless of how little time you have to cook!

Bluefish is abundant in the more desired omega fatty acid which you might know as Omega-3. These types of fatty acids are a fundamental element in preventing cerebrovascular health problems. It’s good to know, bluefish is an ideal supply of minerals such as calcium, iodine, iron, potassium or phosphorus. It also contains fat-soluble vitamins that will help preserve strong bones.

Equipment and method matters

A good food processor is also crucial because we want to save some time. However, if you feel old-fashioned, the way we often feel, simply get a cutting board and a sharp knife. It’s much easier than you think. Make sure you preheat the oven for the crispiest effect and explore the selection of dips we recommend with this creation. From our unique Hollandaise sauce, quail egg mayonnaise, and Keto ajvar to the most adequate tartar sauce! I am sure this will be your next favourite fish burger recipe!

Prep time


Cooking time






  • 400 g mackerel filet (or another type of bluefish)

  • 2 medium eggs (boiled)

  • 2 medium eggs (raw)

  • 150 g grated or chopped zucchini

  • 4 cloves garlic

  • 40 g melted butter

  • 2 tbsp fresh dill

  • 1/2 tsp black pepper

  • 50 ml lemon juice

  • 50 g crumbled feta cheese


  • If you use frozen fish, make sure it’s properly defrosted before starting. Place all the ingredients in a food processor and process till you get a smooth paste. (If you are preparing the ingredients manually, finely chop everything. In the end, add raw eggs, melted butter and lemon juice. Mix with your hands.
  • Cover the mixture with plastic foil and leave it in the refrigerator for at least 30 minutes.
  • Preheat the oven to 180ºC (350ºF). Divide the mixture into 4 parts and shape 4 medium burgers. We believe 2 burgers are a decent portion for an adult. Place them on a baking sheet lined with parchment paper. Bake for 25 minutes.
  • Serve the burgers warm with your favourite Keto-friendly dip or with a small green salad seasoned with olive oil, sea salt, herbs and lemon juice.


  • After the mixture cools down in the refrigerator you will be able to create burgers or small balls because the butter and eggs will thicken the consistency.
  • For larger amount of portions, increase the number in the servings section.
