Ingredients:
- 9-12 pieces breaded fish burgers (or fish filets, store bought or homemade, quantity will vary depending on size of fish used)
- 12 slider buns (or dinner rolls)
- 2 tbsp butter (melted)
- 12 slices American cheese (or slices cheddar cheese)
- 3/4 cup Mayonnaise
- 1/2 cup sweet relish (or finely minced pickles (dill or sweet))
- 1/2 tbsp dried dill (if using regular relish or diced dill pickles uses only 1/4 tbsp of dried dill)
- 1 tbsp lemon juice
Preparing the Fish Patties
Baking the Fish Burgers
First, let’s get our fish burgers ready for assembly. If you’re using store-bought breaded fish burgers, follow the package instructions for baking. Typically, this involves preheating your oven to around 400°F (200°C). Arrange the frozen fish burgers in a single layer on a baking sheet lined with parchment paper for easier cleanup. Parchment paper also helps prevent them from sticking. Bake for approximately 15-20 minutes, flipping them halfway through to ensure even cooking and a golden-brown crust on both sides. The exact cooking time will depend on the thickness and size of your fish burgers. You want them to be thoroughly heated through and crispy. If you are using fresh fish filets, you will need to bread and cook them. You can pan-fry them in a bit of oil until golden and cooked through, or bake them using a similar method. For this recipe, we’re aiming for that classic Filet-O-Fish texture, so a nice crispy exterior is key.
Crafting the Tangy Tartar Sauce
Mixing the Sauce Ingredients
While the fish is baking, we can prepare our delicious and tangy tartar sauce. In a medium-sized bowl, combine the mayonnaise, sweet relish (or your finely minced pickles), dried dill, and lemon juice. If you are using regular relish or diced dill pickles, you will want to slightly reduce the amount of dried dill to about 1/4 tablespoon, as these ingredients can already be quite flavorful. The lemon juice adds a bright, zesty counterpoint to the richness of the mayonnaise and the sweetness of the relish, creating that signature tartar sauce flavor profile. Stir all of these ingredients together until they are well combined and have a consistent texture. Taste the sauce and adjust the seasonings as needed. You might want a little more lemon juice for extra tang, or perhaps a pinch of salt and pepper if you feel it’s lacking. This sauce is incredibly versatile and can be used as a dipping sauce for fries or other seafood as well.
Assembling the Sliders
Toasting the Buns
Once your fish burgers are cooked and your tartar sauce is ready, it’s time to assemble these delightful Filet-O-Fish Sliders. The first step in assembly is to prepare the slider buns. Carefully slice each slider bun in half horizontally. You can do this with a serrated knife for a clean cut. For an extra layer of flavor and a lovely golden hue, we’re going to lightly toast the cut sides of the buns. Melt the 2 tablespoons of butter in a small saucepan over low heat, or in the microwave for about 30 seconds. Once melted, lightly brush the cut sides of the slider buns with the melted butter. You can then either place them cut-side down in a dry non-stick skillet over medium-low heat for a minute or two until lightly golden and fragrant, or place them on a baking sheet and toast them in the oven alongside the fish for the last few minutes of cooking, keeping a close eye to prevent burning. A lightly toasted bun provides a much better structure and adds a pleasant texture to the finished slider.
Layering the Components
Now for the fun part – building your sliders! Start with the bottom half of each toasted slider bun. Generously spread a layer of your prepared tartar sauce onto the cut side of the bottom bun. Don’t be shy with the sauce; it’s a key component of the flavor! Next, take one of your perfectly cooked, crispy breaded fish burgers and place it on top of the tartar sauce. If your fish burgers are a bit large, you might need to trim them slightly to fit neatly within the confines of the slider bun. For that classic Filet-O-Fish experience, the next crucial layer is the cheese. Place one slice of American cheese (or cheddar, if you prefer) directly on top of the warm fish burger. The residual heat from the fish will begin extract to gently melt the cheese, creating that wonderfully gooey and delicious finish.
Finishing the Assembly
To complete your Filet-O-Fish Sliders, take the top half of each toasted slider bun. Spread another, perhaps slightly smaller, dollop of tartar sauce on the cut side of the top bun. This adds another burst of flavor and helps hold the top bun in place. Carefully place the top half of the bun onto the cheese-covered fish burger. You should now have a beautifully layered slider with a crispy fish patty, melted cheese, and that signature tangy tartar sauce, all nestled within a soft, toasted bun. Repeat this layering process for all your sliders. You can serve these immediately while the fish is hot and the cheese is melty. They are perfect for parties, game days, or just a fun weeknight meal. The combination of textures and flavors – the crisp fish, the soft bun, the creamy, zesty sauce, and the melted cheese – makes these sliders utterly irresistible. Enjoy your homemade taste of a fast-food favorite!

Frequently Asked Questions:
Can I make the fish patties ahead of time?
Yes, you absolutely can! You can form the fish patties and store them in the refrigerator for up to 24 hours before cooking. For longer storage, freeze them on a baking sheet until firm, then transfer to an airtight container or freezer bag.
What’s the best way to ensure the fish stays moist?
The key to moist fish is not to overcook it. Cook the patties until they are just opaque and flake easily with a fork. Overcooking will result in dry fish. Also, using fresh, good-quality fish will make a significant difference.
