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 use only 1/4 tbsp of dried dill)
- 1 tbsp lemon juice
Preparation and Cooking
Assembling the Tartar Sauce
The first step to creating these delightful Filet-O-Fish Sliders is to prepare the essential tartar sauce. This is where a lot of the classic flavor comes from, so don’t skimp on the quality of your ingredients here. In a medium-sized bowl, combine the mayonnaise, sweet relish, dried dill, and lemon juice. If you are using minced pickles instead of relish, ensure they are very finely chopped so they integrate smoothly into the sauce. The amount of dried dill will depend on what you are using for your pickle component. If you opted for sweet relish or sweet diced pickles, use the full 1/2 tablespoon of dried dill. However, if you’ve chosen dill pickles (whether sweet or dill), which already have a stronger dill flavor, I recommend reducing the dried dill to 1/4 tablespoon to avoid an overpowering taste. Stir everything together thoroughly until all the ingredients are well incorporated and you have a creamy, zesty sauce. Taste it and adjust the lemon juice or dill to your preference. Some people enjoy a tangier sauce, while others might prefer a more herb-forward flavor. Cover the bowl and refrigerate this mixture while you prepare the other components. This allows the flavors to meld together beautifully.
Preparing the Fish Patties
Next, we focus on the star of our sliders: the fish burgers. If you’re using store-bought breaded fish burgers, follow the package instructions for cooking. Typically, this involves baking or pan-frying them until they are golden brown and cooked through. For baking, preheat your oven to the temperature specified on the packagin extractg (usually around 400°F or 200°C). Arrange the frozen fish burgers on a baking sheet lined with parchment paper for easy cleanup. Bake for the recommended time, flipping them halfway through, until they are heated through and the breading is crisp. If you’re pan-frying, heat a tablespoon or two of oil in a non-stick skillet over medium-high heat. Carefully place the fish burgers in the hot oil and cook for about 3-4 minutes per side, or until they are golden brown and crispy. If you’re using fish filets, you’ll need to bread and fry them yourself. A common method is to season the filets, then dredge them in flour, dip them in beaten egg, and finally coat them in panko breadcrum extractbs for extra crispiness. Then, pan-fry them in about 1/2 inch of oil until golden brown and cooked through. Regardless of your chosen method, ensure the fish is cooked to an internal temperature of 145°F (63°C). Once cooked, place the fish burgers on a plate lined with paper towels to absorb any excess oil.
Toasting the Slider Buns
While the fish is cooking or resting, it’s time to prepare the slider buns. To achieve that perfect balance of soft interior and slightly crisp exterior, we’ll lightly toast them. Split each slider bun or dinner roll in half horizontally. In a small saucepan or microwave-safe bowl, melt the 2 tablespoons of butter. Once melted, brush the cut sides of the slider buns generously with the melted butter. You can also use a pastry brush for this. Alternatively, if you prefer a less buttery bun, you can simply place the cut sides down in a dry, non-stick skillet over medium heat until lightly golden. Once buttered, arrange the bun halves, cut side up, on a baking sheet. Place them under a broiler for a minute or two, keeping a very close eye on them as they can burn quickly. Alternatively, you can toast them in a toaster oven or even directly in the skillet you used for the fish if it’s clean. The goal is to achieve a light golden brown color and a slightly firm texture, which will prevent the buns from becoming soggy when you assemble the sliders.
Assembling the Sliders
Now for the most satisfying part: assembling your Filet-O-Fish Sliders! Start with the bottom half of each toasted slider bun. Generously spread a layer of your prepared tartar sauce on the cut side. Don’t be shy with the sauce; it’s what makes these sliders so delicious! Next, carefully place one cooked breaded fish burger on top of the tartar sauce on each bun bottom. Ensure the fish burger fits comfortably on the bun. If your fish burgers are larger, you might need to trim them slightly or use fewer per slider if they are very substantial. Immediately after placing the fish, lay one slice of American cheese (or cheddar cheese) over the warm fish burger. The residual heat from the fishgin extractll begin to gently melt the cheese, creating that irresistible gooey factor. If you want an even meltier cheese, you can pop the assembled bottom half with the fish and cheese under a warm broiler for about 30 seconds, just until the cheese starts to bubble and melt.
Final Touches and Serving
Once the cheese is in place and has begun to melt beautifully, it’s time to complete the sliders. Take the top half of each toasted slider bun and place it on top of the cheese-covered fish patty. Gently press down to secure everything. You should now have a cluster of perfectly assembled Filet-O-Fish Sliders, ready to be devoured. For the best experience, serve these sliders immediately while they are warm and the cheese is still melty. You can serve them as a delightful appetizer for a party, a quick and satisfying lunch, or even a fun weeknight dinner. They pair wonderfully with classic sides like french fries, coleslaw, or a simple side salad. If you have any leftover tartar sauce, keep it in the refrigerator for dipping or to serve alongside the sliders. These sliders are a fantastic way to enjoy the classic Filet-O-Fish flavor in a fun, bite-sized format that’s perfect for sharing – or not sharing, we won’t judge! Enjoy the delicious combination of crispy fish, creamy tartar sauce, and melty cheese, all nestled within a soft, toasted bun.
