Filet-O-Fish Sliders Ingredients
For the Fish
- Breaded Fish Burgers/Filets – Provide the main protein source; use store-bought or homemade for tastier results.
For the Buns
- Slider Buns – Form the base and structure of the slider; substitute with dinner rolls if desired.
- Butter (melted) – Adds golden color and flavor to the buns; can use olive oil for a lighter option.
For the Tartar Sauce
- Mayonnaise – Acts as the base for the tartar sauce; substitute with Greek yogurt for a healthier twist.
- Sweet Relish (or minced pickles) – Provides sweetness and tang to the tartar sauce; use dill pickles for a different flavor profile.
- Dried Dill – Adds a herbal note to the tartar sauce; fresh dill can be substituted when in season.
- Lemon Juice – Brightens the flavor of the tartar sauce; lime juice can be a suitable alternative.
For the Cheesy Layer
- American Cheese or Cheddar Cheese (slices) – Provides creaminess and flavor; swap for a dairy-free alternative for vegan sliders.
Step‑by‑Step Instructions for Filet-O-Fish Sliders
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven is heating, line two baking sheets with parchment paper or foil to catch any drips. This simple prep will help ensure your Filet-O-Fish Sliders come out perfectly golden and delicious!
Step 2: Bake the Fish
Place your breaded fish filets on the prepared baking sheets and bake them according to the package instructions, usually about 15-20 minutes, or until they are golden brown and crispy. You’ll know they’re ready when they reach an internal temperature of 145°F (63°C) and are visibly crunchy on the outside.
Step 3: Make the Tartar Sauce
While the fish is baking, it’s time to whip up a creamy homemade tartar sauce. In a mixing bowl, combine mayonnaise, sweet relish, lemon juice, and dried dill. Stir until mixed well and then cover the bowl and chill in the refrigerator until your sliders are ready for assembly. The coolness will enhance the flavors!
Step 4: Toast the Buns
Once the fish is nearly cooked, melt some butter in the microwave or on the stove. Remove the buns from their packaging, brush them lightly with the melted butter, and place them in the oven for 2-3 minutes. They should be warm and slightly crispy, ready to cradle all the deliciousness of the Filet-O-Fish Sliders.
Step 5: Assemble the Sliders
After the fish is done baking, take the buns out of the oven and slice them in half. Start by layering a slice of cheese on the bottom half of each bun. Next, place a crispy fish filet on top of the cheese, allowing it to melt slightly, then generously spread your tartar sauce over the fish.
Step 6: Close and Serve
Finally, place the top half of the buns onto the assembled sliders. You can slice them into smaller portions if desired, making them perfect for sharing. Serve your Filet-O-Fish Sliders immediately while they’re hot and fresh, and watch your family dive in for an exciting meal!

How to Store and Freeze Filet-O-Fish Sliders

Reheating: When ready to enjoy, thaw in the fridge overnight, then reheat in the oven at 350°F for 10-15 minutes until warmed through. Avoid reheating with tartar sauce to keep it fresh and creamy.
