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 Buns and Tartar Sauce
Step 1: Toasting the Slider Buns
First things first, let’s get those slider buns ready. You want them to have a nice golden-brown hue and a slightly crispy texture, which will prevent them from getting soggy under the fish and sauce. Take your 12 slider buns (or dinner rolls if you’re using those) and carefully slice each one in half horizontally. This creates the top and bottom halves. Next, grab your melted butter. Using a pastry brush or a spoon, generously brush the cut sides of each bun half with the melted butter. You can also do this in batches if you have a large griddle or frying pan. Place the buttered sides down onto a preheated griddle or non-stick skillet over medium heat. Toast them for about 2-3 minutes, or until they turn a beautiful golden brown. Keep a close eye on them, as they can burn quickly. Once toasted, set them aside, keeping the top and bottom halves together for each bun so you don’t mix them up.
Step 2: Crafting the Tangy Tartar Sauce
Now, let’s whip up a quick and delicious tartar sauce that will elevate our sliders. In a medium-sized bowl, combine your mayonnaise. To this, add the sweet relish. If you’re using finely minced dill pickles instead of sweet relish, be sure to mince them very finely so they blend well into the sauce. This is also where you’ll add your dried dill. If you’re using sweet relish or diced dill pickles, start with 1/4 tablespoon of dried dill, and then add the full 1/2 tablespoon if you’re using regular relish or plain diced dill pickles for a more pronounced dill flavor. Finally, add the tablespoon of fresh lemon juice. The lemon juice is crucial here as it cuts through the richness of the mayonnaise and adds a bright, zesty note. Whisk all of these ingredients together thoroughly until everything is well combined and the sauce has a consistent texture. Taste it and adjust the seasoning if you like – maybe a pinch more salt or pepper, or even a touch more lemon juice for extra tang. This sauce is best made a little ahead of time, allowing the flavors to meld, so cover it and pop it in the refrigerator while you prepare the fish.
Cooking the Fish and Assembling the Sliders
Step 3: Cooking the Breaded Fish Burgers
It’s time to cook the star of our show – the breaded fish burgers! You can cook these using your preferred method, but pan-frying or baking are excellent options for achieving a crispy exterior. If you’re pan-frying, heat a tablespoon or two of neutral oil (like vegetable or canola oil) in a skillet over medium-high heat. Once the oil is shimmering, carefully place your breaded fish burgers into the skillet. Don’t overcrowd the pan; cook them in batches if necessary. Fry them for about 3-5 minutes per side, or until they are golden brown and heated through. If you prefer to bake them, preheat your oven to 400°F (200°C). Place the breaded fish burgers on a baking sheet lined with parchment paper. Bake for 15-20 minutes, flipping halfway through, until they are golden and crispy. The exact cooking time will depend on the thickness and size of your fish burgers, so ensure they are cooked through and have a lovely crisp coating.
Step 4: Melting the Cheese onto the Fish
This step is crucial for achieving that signature Filet-O-Fish vibe. Once your fish burgers are cooked, it’s time to get that cheese melty and gooey. If you’re pan-frying, you can do this directly in the skillet. After flipping the fish burgers, place a slice of American cheese (or cheddar, if you prefer) on top of each one. Cover the skillet for about a minute or two, allowing the residual heat to melt the cheese beautifully. The steam trapped under the lid will help it melt evenly. If you’ve baked your fish burgers, you can achieve the same result by placing a slice of cheese on each burger after removing them from the oven. You can then place them back in the oven for a minute or two, or simply cover them with foil for a few minutes to let the cheese melt. The goal is a wonderfully melted, slightly draped slice of cheese clingin extractg to the warm fish.
Step 5: Assembling Your Filet-O-Fish Sliders
We’re in the home stretch! It’s time to bring all our delicious components together to create these irresistible sliders. Start with the toasted bottom halves of your slider buns. Generously spread a good dollop of your homemade tartar sauce onto each one. Don’t be shy; this is where a lot of the flavor comes from! Next, carefully place one of the cheese-covered fish burgers on top of the tartar sauce on each bottom bun. Now, take the toasted top halves of the buns. You can add a little extra tartar sauce to the underside of the top bun if you like, or leave it plain. Gently place the top bun onto the fish burger. Press down slightly to help everything settle. Repeat this process for all your sliders. You should have 9 to 12 perfectly formed Filet-O-Fish sliders ready to be devoured. Serve them immediately for the best crispy texture and gooey cheese.
