Best Sauce for Fish Burger [10 Delicious Ideas]

Best Sauce for Fish Burger
Share on:

Fish burgers gained popularity thanks to McDonald’s filet-o-fish sandwich that was introduced to the menu of this fast-food chain in the early 60s. There are many delicious versions of this meal, and you can pair it with a variety of sauces. Still, what is the best sauce for a fish burger?

You can enhance the taste of your fish burger with anything from homemade mayonnaise, ketchup, classic burger sauce, tartar, lemon aioli, Remoulade, garlic butter sauce, to chimichurri, pesto, and greek mint sauce.

There are many sauces that can enhance the taste of your fish burger, and in the following text, you will find a list of the best ones.  

Homemade Mayonnaise

Mayonnaise is a simple and classic addition to any sandwich, and it becomes even better if you make it yourself. All you need is mustard, oil, egg yolk, lemon juice, and salt. 

Homemade sauce is more beneficial for your health in comparison to store-bought mayo. It doesn’t include chemicals like store-bought mayonnaise and is a source of vitamins E and K. It takes 2-3 minutes to make and goes well with any fried food.

One cup of homemade mayo contains about 1,440 calories, so there are definitely better solutions than this if you are trying to lower your daily intake of calories. However, you can try out the vegan version made with mustard, boiled potatoes, and almond milk. 

Ketchup Sauce

Homemade ketchup sauce is another classic that will enrich the taste of your fish burger. Though it will take more time to make than it would to go to the shop and buy a bottle of ketchup, it is a healthy and tasty solution. 

You can make this sauce at home with tomatoes, sugar, honey or brown sugar, vinegar, salt, water, onion, and garlic powder. If you conserve ketchup properly, it can last for a couple of months.

The ketchup, both homemade and store-bought, is also a good base for other sauces. You can mix it with oregano or dill, crushed onions, olive oil, and tomato puree to give it more density and flavor and serve a fish burger with it.


Ketchup vs. Mayo: Differences & Which Is Better

Classic Burger Sauce

Classic burger sauce has several variations, each of which is a true delicacy. It is a perfect addition to any fried meat made from mayonnaise, ketchup, pickle relish, white vinegar, and spices.

Another way to prepare this sauce is by replacing pickle relish and vinegar with mustard, lemon juice, and buffalo sauce. The taste will be slightly different but rich and piquant.

Tartar Sauce

Best Tartar Sauce for Fish Burger

This sauce is one of the most common additions to the fish burger. It contains mayonnaise, doll, pickles, finely chopped onions, lemon juice, sugar, and pepper. 

Creamy mayonnaise base and onion, pickle tangy, fresh taste the sauce compliment fish meat, while the acidic and bright note of lemon juice balances the entire meal. Tartar sauce is versatile, and you can pair it with various types of fish meat. 

If you notice that the onion tastes too strong for the sauce, peel it, place it in a bowl of warm water, and use it after half an hour.

Lemon Aioli

Lemon aioli is another sauce with a mayonnaise base. It also contains minced garlic, lemon juice, salt, and pepper. This sauce is simple to prepare, and you can change the amount of lemon or garlic to make it according to your preferences.

Garlic Butter Sauce

This delicious spicy sauce works well with fish in any way you prepare it. You can make it with unsalted butter, minced garlic, fresh parsley, salt, pepper, and red pepper flakes. All you need to do is to melt the butter in a saucepan and add the rest of the ingredients.

The best option is to use garlic sauce right after you make it, but you can also store it in a glass container with an airtight seal and refrigerate it. Bear in mind that the butter will become hard once it cools, so you need to heat the sauce once you get it out of the fridge.


Remoulade is a sauce French culinary masters designed to compliment the taste of various seafood. You can make it with mayonnaise, Dijon mustard, shallots, fresh parsley, capers, pickles, lemon juice, Tabasco sauce, and salt and pepper.

Remoulade pairs well with a fish burger because of its acidic and spicy note. However, if you want to make it less intense, add a mild hot sauce instead of Tabasco or cut the amount of lemon juice.

Chimichurri Sauce

South American chimichurri sauce is a popular choice for various dishes, but its fragrance makes it a perfect match for a fish burger. It contains herbs, garlic, olive oil, and vinegar.

Chimichurri sauce usually contains herbs such as cilantro, parsley, and oregano, which make it more aromatic and flavorful. It is a great choice if you want to turn your fish burger into a more elegant and exotic meal. 

In case you are not planning to use it immediately, you can store it in the fridge until the next meal. However, avoid refrigerating it for more than a day.


One of the favorite Italian sauces, pesto, is a good match for pasta plates with prosciutto and any meal with fish meat. It includes fresh oregano, parmesan cheese, pine nuts, minced garlic, olive oil, salt, and black pepper.

Pesto has an intense flavor, so I advise you to mix it with a few tablespoons of cooking cream and heat it until it becomes creamy. That is a variation of the sauce you should serve right away. However, if you don’t have time for additional cooking, you can simply spread the sauce on a burger without adding cream. 

Greek Mint Sauce

Best Greek Mint Sauce for Fish Burger

Greek mint sauce is a traditional side dish in the Mediterranean country. It contains mashed potatoes, garlic, chopped mint, olive oil, lemon juice, and salt and pepper.

The freshness of the mint and the acidic note from the lemon juice match up very well with fried fish. It is a perfect summer sauce, but that doesn’t mean you cannot add it to your fish burger at any time of the year.
