Hi friends!
If you’re new here—welcome! And if you’ve been around before, welcome back. I’m so glad you’re here today because this one is a keeper.
We’re talking about flounder—delicate, buttery, and flaky with just the right amount of seasoning. It’s one of those “barely a recipe” recipes that feels almost unfair in the best way possible. You get all the flavor, none of the fuss, and dinner on the table before anyone has time to ask, “What’s for dinner?”

✨ Why You’ll Love This Easy Flounder Recipe for Dinner

A tender fillet with a beautifully golden, seasoned topping gives way to moist, delicate flakes at the first touch of your fork. The gentle heat of Old Bay seasoning pairs perfectly with the brightness of fresh lemon, making each bite flavorful and refreshing. Flounder is naturally mild and fresh—never too “fishy”—which makes it a great choice for everyone at the table. It cooks quickly and is almost impossible to overcook, making it the ultimate easy weeknight dinner idea.
This easy flounder recipe is inspired by Samin Nosrat’s cooking philosophy from her cookbook Salt, Fat, Acid, Heat—big flavors, simple techniques, and smart ingredients for seafood lovers and beginners alike.

🍞 Hooked on Flavor: Flounder Dinner Ideas Everyone Will Love

We enjoyed our flounder served over warm garlic naan, using Mariam’s recipe, smeared with fresh ricotta mixed with freshly grated parmesan cheese. Then, we topped them with juicy tomatoes and fresh basil, seasoned simply with garlic, salt and good olive oil.

Feel free to get creative here—try adding Calabrian Chile Crisp for some heat, swap ricotta for tangy goat cheese, or pile on some crisp salad greens. You can also make a fish sandwich by piling the fillets on a toasted brioche or potato bun with mayo, lettuce, and tomato.
Pair with a fresh green salad or roasted veggies for a complete, healthy meal. What are you planning? Drop your ideas in the comments!

💡 Pro Tips and Storage Advice for Leftover Flounder

Oven works best for cooking larger batches.
Warm flatbreads with a bit of butter and garlic powder for extra flavor. Mariyam’s recipe makes 14 flatbreads—perfect for a crowd. Want fewer? I’ve got a simple yeasted naan recipe I’ve used for years that makes 4 rounds. Or, if you’re feeling mathematically savvy, feel free to scale either recipe to fit your needs!
Store leftovers in an airtight container in the fridge for up to 2 days. Reheat gently in the oven to keep fish flaky.

Ingredients Equipment Method Notes

Ingredients

1 lb flounder fillets (In my case, this was 2 big fillets)
2 Tbsp mayonnaise
1 tsp Old Bay Seasoning
lemon wedges for garnish
parsley for garnish
kalamata olives (Optional garnish)

Equipment

air fryer or sheet pan for oven

Method

Preheat your air fryer to 400ºF or oven to 450℉
Pat the flounder fillets dry with paper towels. Arrange them on a parchment liner sized to fit your air fryer basket or sheet pan. Spread the mayonnaise evenly over the top of each fillet, then sprinkle evenly with Old Bay seasoning.
Air fry or bake the flounder until golden brown and the flesh flakes easily with a fork, about 10 minutes (8 minutes for very thin fillets; up to 12–15 minutes for thick ones). If using the broiler as an alternate cooking method, place the fish on a lightly oiled, foil-lined sheet pan to prevent sticking (skip parchment—it can burn under the broiler).
Serve hot with lemon wedges for squeezing over. Heaven!

Notes
