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 Tartar Sauce
Step 1: Combine the Sauce Base
In a medium-sized mixing bowl, combine the mayonnaise and sweet relish. If you’re using finely minced pickles instead of sweet relish, aim for a texture that’s similar to relish – small, uniform pieces. This forms the creamy foundation of our tartar sauce. Stir these two ingredients together until they are thoroughly incorporated. You want a smooth, consistent mixture without any streaks of mayonnaise or pockets of relish. This is where the flavor really begin extracts to develop.
Step 2: Add Flavor Enhancers
Next, it’s time to add the seasonings that will elevate this simple mixture into a delicious tartar sauce. Add the dried dill and the lemon juice to the bowl. The dried dill will impart a wonderfully fresh, herbaceous note, reminiscent of the classic Filet-O-Fish. The lemon juice will cut through the richness of the mayonnaise and provide a bright, tangy counterpoint, making the sauce more appealing and balanced. Whisk everything together until all the ingredients are evenly distributed. Taste the sauce at this stage and adjust the dill or lemon juice to your preference. If you like a stronger dill flavor, you can add a pinch more. If you prefer it tangier, a tiny splash more lemon juice can be added. Remember, this sauce is going to complement the fish, so it should be flavorful but not overpowering.
Cooking the Fish Patties
Step 3: Prepare the Fish
If you are using frozen breaded fish burgers, follow the package instructions for cooking. This typically involves baking them in the oven until they are golden brown and heated through. If you are using fresh fish filets, you will need to bread and cook them. For a homemade breading, you can dip the filets in flour, then egg wash, and finally panko breadcrum extractbs seasoned with salt and pepper. Then, pan-fry them in a little oil until golden and cooked through, or bake them. The key is to ensure the fish is cooked thoroughly and has a nice, crispy exterior. For the purpose of these sliders, it’s best if the fish burgers or filets are roughly the size of your slider buns. If they are too large, you might need to cut them into more manageable pieces before placing them on the buns.
Assembling the Sliders
Step 4: Prepare the Buns and Melt Cheese
While your fish patties are cooking or have just finished, it’s time to get your slider buns ready. Slice each slider bun horizontally in half. This is crucial for creating the layered effect of a slider. Melt the butter in a small saucepan or microwave it until it’s liquid. Brush the cut sides of all the slider buns generously with the melted butter. This will give them a beautiful golden-brown color when toasted and add a lovely richness. Place the buttered buns, cut-side down, onto a baking sheet. You can then place these under a broiler for a minute or two, or pop them into a warm oven, just until they are lightly toasted and slightly crisp. Keep a close eye on them as they can burn quickly. Once the buns are lightly toasted, arrange the slices of American cheese (or cheddar) evenly over the bottom halves of the buns. Place the baking sheet back into the warm oven (or under the broiler again for a very brief moment) for about 30-60 seconds, just until the cheese is melted and gooey. This step ensures perfectly melted cheese that adheres nicely to the bun.
Step 5: Constructing the Filet-O-Fish Sliders
With your buns toasted and cheese melted, you’re ready for the final assembly. Carefully place one cooked breaded fish burger (or filet) onto each of the cheese-covered bottom halves of the slider buns. Ensure the fish is centered on the bun for an even bite. Now comes the best part – generously spread a good amount of your prepared tartar sauce over the top of each fish patty. Don’t be shy with the sauce; it’s a key component of the classic flavor! Aim for about 1-2 tablespoons of sauce per slider, depending on your preference. Finally, place the top half of each slider bun over the tartar sauce to complete your Filet-O-Fish Sliders. Serve them immediately while they are warm and the fish is crispy, and the cheese is delightfully melty. These sliders are perfect for a casual meal, a party appetizer, or whenever you’re craving that nostalgic fish sandwich flavor in a fun, bite-sized format.
