What makes these sliders truly special is their versatility; they’re perfect for a weeknight family dinner, a crowd-pleasing appetizer at your next barbecue, or even a creative addition to a themed party. We’ve perfected a recipe that balances that familiar taste with a homemade touch, ensuring each little burger is a burst of deliciousness you’ll want to make again and again.
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
Prepare the Tartar Sauce
Step 1: Combine the Sauce Ingredients
This is where we create the classic tangy sauce that elevates our fish sliders. In a medium bowl, combine the mayonnaise, sweet relish, dried dill, and lemon juice. If you’re using finely minced pickles instead of sweet relish, make sure they are very finely chopped so they integrate smoothly into the sauce. Remember to adjust the amount of dried dill if you’re using dill pickles – starting with 1/4 tablespoon is a good idea to avoid an overpowering dill flavor. Whisk everything together until it’s well combined and has a creamy, consistent texture. Taste it and adjust the lemon juice or relish if you prefer it tangier or sweeter. This sauce can be made ahead of time and refrigerated, allowing the flavors to meld beautifully. It’s the secret weapon for that authentic Filet-O-Fish flavor!
Cook the Fish
Step 2: Cook the Breaded Fish Burgers
Now it’s time to get our fish ready. You’ll want to cook your breaded fish burgers according to their package instructions if they are store-bought. This usually involves baking or air frying for best results and a crispier coating. If you’re using homemade fish filets, you’ll likely want to pan-fry them until golden brown and cooked through. For baking, preheat your oven to the temperature specified on the packagin extractg, typically around 400°F (200°C). Place the fish burgers on a baking sheet lined with parchment paper for easy cleanup. Bake for the recommended time, usually 15-20 minutes, flipping halfway through to ensure even cooking and crisping. If air frying, follow your air fryer’s guidelines, which often involve a similar temperature and time. The goal is a perfectly cooked, flaky interior with a delightfully crunchy exterior.
Toast the Buns
Step 3: Prepare the Slider Buns
While the fish is cooking, we’ll prepare our slider buns. These little buns are the perfect vehicle for our delicious fish. Carefully slice each slider bun in half horizontally. In a small bowl, melt the 2 tablespoons of butter. Using a pastry brush or the back of a spoon, lightly brush the cut sides of both the top and bottom halves of the slider buns with the melted butter. This step is crucial for achieving that desirable golden-brown crisp and adding a wonderful buttery flavor to the buns, mimicking the classic burger experience. You can toast the buns in a few ways: place them cut-side down on a dry skillet over medium heat until lightly golden, or place them on the baking sheet with the fish for the last few minutes of cooking, cut-side up. Keep a close eye on them as they can toast quickly.
Assemble the Sliders
Step 4: Layer the Cheese and Tartar Sauce
This is where the magic happens! Once the fish is cooked and the buns are toasted, it’s time to assemble these delightful Filet-O-Fish sliders. Take the bottom halves of your toasted slider buns and place them on your work surface. Immediately top each bottom bun with a slice of American cheese (or cheddar, if you prefer). The residual heat from the fish will help the cheese start to melt. Now, spoon a generous amount of the prepared tartar sauce onto the cheese. Don’t be shy with the sauce – it’s a key component of the flavor profile! Ensure you distribute it evenly across the cheese.
Step 5: Add the Fish and Top the Buns
Gently place a cooked breaded fish burger on top of the tartar sauce on each bottom bun. If your fish burgers are a bit larger than the buns, you might need to trim them slightly to fit, or simply let them overlap a little. Now, take the top halves of your toasted slider buns, which should also have a lovely golden hue from the butter. Place these top buns directly onto the fish, completing each slider. You can press down gently to help everything settle. If you want your cheese to be extra melty, you can briefly place the assembled sliders back into a warm oven for 1-2 minutes or cover them with a foil tent for a few minutes to allow the heat to work its magic. Serve immediately for the best texture and flavor!
