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 warms up, grab two sheet pans and line them with parchment paper or foil to simplify cleanup. This will be crucial for your Filet-O-Fish Sliders, keeping everything organized and making way for that crispy fish goodness.
Step 2: Bake the Fish
On one of the lined sheet pans, arrange your breaded fish burgers in a single layer. Follow the package instructions for baking, typically around 15-20 minutes, until they are golden brown and crisp. Keeping the fish warm and ready will ensure your sliders have a delightful crunch.
Step 3: Mix Up the Tartar Sauce
While the fish is baking, it’s time to prepare your creamy tartar sauce. In a mixing bowl, combine ¾ cup of mayonnaise, ½ cup of sweet relish, 1 tablespoon of lemon juice, and ½ tablespoon of dried dill. Stir everything together until smooth and well-blended. Pop your sauce in the fridge to chill while the fish finishes cooking.
Step 4: Prepare the Slider Buns
Next, take the remaining sheet pan and lay out the slider buns. Brush the tops with 2 tablespoons of melted butter for added flavor and moisture. Place the buns in the oven and warm them for 2-3 minutes. They should be lightly toasted, ready to cradle the delicious fillings of your Filet-O-Fish Sliders.
Step 5: Slice and Get Ready to Assemble
After warming, carefully remove the buns from the oven and let them cool for a minute. Slice each bun in half, keeping the tops and bottoms separate. The slightly crispy edges will add a great texture to your sliders, preparing them for the tasty builds ahead.
Step 6: Assemble the Sliders
Now, it’s assembly time! On each bottom half of the slider bun, place a slice of American cheese, followed by the hot, crispy fish from the oven. Generously spread your chilled tartar sauce over the fish. This is the moment when your Filet-O-Fish Sliders start to come to life, combining all those delightful flavors.
Step 7: Cap and Serve
Finish off by placing the tops of the slider buns over the sauced fish. If desired, slice the assembled sliders in half for easy serving. These Filet-O-Fish Sliders are now ready to be savored; serve them fresh and watch everyone enjoy this fun, homemade take on a classic favorite!

Filet-O-Fish Sliders Recipe FAQs
What type of fish is best for Filet-O-Fish Sliders?
For the crispiest and most delicious Filet-O-Fish Sliders, I recommend using breaded fish burgers made from white fish like cod or pollock. These types of fish provide a mild flavor and a flaky texture that pairs beautifully with the tartar sauce. If you prefer a healthier option, you can also make homemade cornflake-crusted fish fillets for a delightful crunch.
How should I store leftover Filet-O-Fish Sliders?
Absolutely! Store any unassembled sliders in an airtight container in the refrigerator for up to 3 days. To keep the buns from becoming soggy, I suggest storing the tartar sauce separately and adding it just before serving. This way, you can maintain their delicious crispiness and freshness.
Can I freeze cooked Filet-O-Fish Sliders?
Yes, you can! If you plan ahead, assemble your sliders without tartar sauce and freeze them. Wrap each slider tightly in plastic wrap and then place them in a freezer-safe bag. They can last up to 3 months in the freezer. When you’re ready to enjoy them, just bake them straight from frozen at 350°F (175°C) for about 10-15 minutes until heated through.
Are there any allergy substitutions I should be aware of?
Great question! If you or your loved ones have allergies, consider substituting key ingredients. For example, you can make the tartar sauce dairy-free by using a plant-based mayonnaise. Also, if gluten is an issue, be sure to use gluten-free buns and fish. Always check labels for hidden allergens, such as in relishes or sauces used in the recipe.
How can I make a vegetarian version of Filet-O-Fish Sliders?
For a delightful vegetarian twist, substitute the fish with a plant-based fish burger available at many grocery stores. Alternatively, you could use a breaded portobello mushroom cap for a hearty base. Simply follow the same baking instructions, and your family will love this meatless version just as much!
What if my fish doesn’t turn out crispy?
If you find that your fish isn’t as crispy as you’d like, ensure that your oven is preheated properly before baking. Also, avoid stacking the fish on top of each other while baking, as this can cause steaming instead of crisping. Lastly, for an even crunchier finish, try finishing them under the broiler for the last couple of minutes of cooking. Enjoy experimenting!
