π©βπ³ How to Make It
1. Prepare the Crispy Flounder
Preheat the oven to 400Β°F (200Β°C) and line a baking sheet with parchment paper.
In a small bowl, combine the toasted panko breadcrumbs, melted butter, and Old Bay seasoning. Press the mixture firmly onto the top of each flounder fillet. Arrange the fillets on the prepared baking sheet and bake for 12β15 minutes, or until the coating is golden brown and the fish flakes easily with a fork.
2. Make the Apple Slaw
In a medium bowl, toss together the julienned green apple, shredded cabbage, apple cider vinegar, and celery seed until evenly coated. Let the slaw rest for a few minutes to allow the flavors to meld while maintaining its crisp texture.
3. Prepare the Lemon Tartar Crema
Whisk together the mayonnaise, sweet pickle relish, fresh lemon juice, and chopped dill until smooth, creamy, and well combined.
4. Assemble the Sliders
Spread a generous layer of the lemon tartar crema onto the bottom half of each toasted brioche slider bun. Top with a crispy baked flounder fillet, then pile on the crunchy apple slaw. Finish with the top bun.
5. Serve and Enjoy
Serve the sliders immediately while the fish is hot and crispy. Pair with kettle chips, sweet potato fries, or a fresh green salad for a complete meal.
