- Easy to customize: You can swap out the ingredients easily to use what you have or what you prefer
- Quick and simple: These sliders don’t take long to make so are ideal for evenings when time is short.
Ingredients Needed
I’ve highlighted a couple of ingredients below with some relevant notes. Aside from this, the ingredients needed are pretty basic.
- Buns – We used Hawaiian slider buns as there are 9 in the pack.
- Fish fillets – I bought 8 fish fillets for the recipe but only ended up using 7 to fill the sandwiches.
- Cheese – Any good American cheese will work nicely for this recipe.
Substitutions
Sometimes substitutions are necessary because of ingredients that are unavailable or needed for dietary restrictions. Here are some suggestions that can help:
- Hawaiian slider buns: If you can’t find Hawaiian slider buns or prefer a different type, you can easily substitute them with any small-sized buns. If you’re watching your carbs, consider using whole wheat or multigrain slider buns. For an extra zing, pretzel buns can be an interesting choice.
- American cheese: If American cheese isn’t your favorite or if you’re looking for a healthier option, try using a slice of sharp cheddar for a more robust flavor or a slice of provolone for a milder taste. For those who are lactose intolerant or vegan, there are many non-dairy cheeses available in the market that melt well and taste great.
Variations
If you want to add a unique twist to these Fish Sliders, here are a few suggestions that you might want to consider:
- Go spicy: If you’re a fan of heat, consider adding a layer of spicy mayo or your favorite hot sauce to your sliders, like we use in our buffalo chicken sliders. You could also sprinkle some crushed red pepper flakes or cayenne pepper on the fish fillets before baking them.
- Add some greens: For an added health kick, you can add a layer of fresh spinach, arugula, this KFC coleslaw recipe, or fresh lettuce to your sliders. This will not only add nutrition but also a nice crunch.
- Try a different protein: If fish isn’t your favorite protein, you can easily substitute it with grilled chicken, turkey, or even a veggie patty for a vegetarian alternative.
- Cheese variety: Experiment with different types of cheese. A smoked gouda or creamy brie can take your sliders to a whole new level of deliciousness.
- Add pickles: For a tangy crunch, consider adding sliced pickles to your sliders. Dill or bread and butter pickles both work great.
How to Make Fish Sliders
*Be sure to see the recipe card below for the full ingredients list & instructions!*
STEP 1: Cook the fish fillets. Preheat the oven to 425 degrees Fahrenheit, or as directed on the packaging of your frozen fish filets. Proceed to cook them according to the package instructions. (Image 1 and 2)
STEP 2: Mix the butter. In the meantime, combine butter and ½ teaspoon of Old Bay seasoning in a separate bowl, then heat them together in the microwave for approximately 30 seconds until melted. (Image 4)
STEP 3: Make the sauce (optional). Prepare the optional sauce by combining the ingredients together. (Image 5-6)
STEP 4: Layer the cheese and butter. Begin by slicing the buns in half. Place a layer of cheese on the bottom buns and generously spread melted butter and seasonings on the top bun. (Image 7-9)
STEP 5: Add extra butter (optional). If desired, you can utilize any remaining melted butter to brush the buns once they are out of the oven. (Image 8)
STEP 6: Heat the sliders. Preheat the oven to 425 degrees and bake for 2-3 minutes, or until the cheese has melted to perfection (Image 10)
STEP 7: Add a piece of fish and sauce then serve. Take out from the oven and place a portion of fried fish on each bun (you may need to cut some pieces in half to fit better). Drizzle with sauce, slice the buns into individual sliders, and savor the deliciousness. (Images 11-14)
Recipe Pro Tips
- Choosing the fish: Opt for a mild white fish like cod, haddock, or tilapia. These types are less “fishy” and work great for sliders.
- Cooking the fish: Make sure not to overcook the fish. It should be flaky and moist, not dry.
- Melting the cheese: Be watchful while melting the cheese in the oven. It should melt evenly and not burn.
- Serving hot: Serve the Fish Sliders hot for the best taste. If you’re preparing them in advance, you can reheat them in the oven before serving.
- Experiment with sauce: Don’t be afraid to play around with the sauce. You can add more or less of the ingredients to suit your personal preference.
- Slider size: Ensure the fish fillets are the correct size for your slider buns, so they don’t overhang. If necessary, cut into smaller fish pieces or use larger buns.
Recipe FAQs
Absolutely! If you have access to fresh fish, feel free to use it in place of frozen. You’ll need to adjust the cooking times appropriately as fresh fish will typically cook faster than frozen.
Yes, you can. While brioche buns are a popular choice for sliders because of their sweetness and soft texture, you can use any type of small bun or roll. Whole wheat or gluten-free buns can be a healthier alternative.
Old Bay is a blend of spices typically used in seafood dishes. If you don’t have it, you can make a similar blend with equal parts of paprika, dry mustard, and celery salt, with a pinch each of black pepper, red pepper flakes, ground nutmeg, and ground cloves.
You can prepare individual items ahead of time, but they’re best assembled and served immediately to maintain the freshness of the fish and the crispness of the buns.
While American cheese is suggested in the recipe, feel free to experiment with your favorite kinds of cheese. Gouda, mozzarella, and Swiss are all delicious options.
What to Serve with Fish Sliders
Fish Sliders are a versatile dish that pairs well with a variety of sides. Here are some suggestions:
- Crispy Sweet Potato Fries: A healthier alternative to traditional french fries, air fryer sweet potato fries are a delicious companion to fish sliders. Their sweet, earthy taste complements the savory flavors of the sliders perfectly.
- Coleslaw: This classic side dish adds a refreshing crunch to your meal. You can stick with traditional coleslaw or experiment with variations like apple slaw, tangy red cabbage slaw, or a coleslaw mix.
- Green Salad: A simple green salad with a light vinaigrette dressing can be a nice, light accompaniment to balance out the heartiness of the sliders.
- Pickle Spears: The tangy flavor of pickles pairs well with the rich flavors of the fish and cheese. Plus, they add a nice crunch to your meal.
- Pasta Salad: A chilled pasta salad, especially one with a tangy vinaigrette, can make a wonderful side for these hearty sliders.
Storage
Storing leftover Fish Sliders is a breeze and can come in handy for quick meals throughout the week. Firstly, let the sliders cool down completely. Transfer them to an airtight container or wrap them individually in cling wrap or aluminum foil. Leftover Fish Sliders can be stored in the refrigerator for up to 3 days.
To reheat, preheat the oven to 350 degrees and bake for approximately 10 minutes, or until the sliders are warmed through and the cheese is melty.
It is not recommended to freeze them as the texture of the fish and buns can become soggy upon thawing.
