This flounder with lemon butter sauce is easy, healthy, quick, elegant, family-friendly, and requires that you clean up only a single skillet. That’s to say nothing of its crisp brown crust and flaky perfection.
Why You Need To Use Fresh, Not Frozen, Fish In This Recipe
Though it may be tempting, don’t substitute frozen fish for fresh in this impressive weeknight-friendly recipe. Frozen fish, no matter how thoroughly you thaw it or pat it dry, will exude quite a lot of moisture during cooking, effectively making it impossible to attain that lovely crisp crust that otherwise forms on fish tossed into a hot skillet. So you end up with soggy steamed fish rather than those crisp edges that give way to tender fish in a way that makes your heart skip a beat. Trust us when we say it’s worth a few extra hard-earned dollars for fresh rather than freezer-case fish.

Pat the fish dry with paper towels and season with salt and pepper. Pat the fillets dry a second time just to be sure to remove all the moisture. If desired, sprinkle a little flour over both sides of the fillets and use your fingers to evenly coat both sides.
Heat the oil in a large skillet (preferably cast-iron or stainless steel rather than nonstick) over medium-high heat until the oil shimmers but isn’t smoking, 1 1/2 to 2 minutes. Add the fillets to the skillet and cook, without moving, for 2 minutes. Slide a thin metal spatula underneath the fillets (making sure to use a little pressure to scrape up any of the golden crust that may be sticking to the bottom) and carefully flip the fish. If it seems impossible to slip the spatula beneath the fillet and the skillet, wait 30 to 60 seconds or so and try again. The fish will release when it’s ready–and only when it’s ready.
Place a slice of butter on top of each fish fillet and stand idly by as the butter melts and infuses the fish with flavor. Cook the fish until it springs back from light pressure, about 2 minutes. Use a spatula to transfer the fish to a platter or to 4 plates.
Carefully squeeze the lemon juice into the skillet and, with the skillet still over medium-high heat, use a wooden spoon to scrape up any browned bits stuck to the bottom of the skillet. Stir in the fresh herbs and spoon the sauce over the fish. Originally published July 26, 2012.
*NOTE: How To Make This Flounder Recipe Gluten-Free
Although a dusting of flour does make for a swell crust on these pan-seared fish fillets, it’s not necessary. There’s an editor here at LC (ahem) who can attest that flour isn’t at all essential for a lovely sear on fish. She sizzles flounder fillets for supper quite frequently in a sturdy stainless steel skillet and they never, ever have a flour coating. It’s just not necessary. If you’re accustomed to the thin coating imparted by flour but are gluten-free, then you can use rice flour in place of all-purpose flour, as noted in the recipe above, and it will work just dandy.

There’s nothing better than simple for dinner. This flounder recipe with lemon butter sauce is easy to prepare and delicious to eat. The preparation allows the fish to shine as the main ingredient.
I chose not to use the flour and just used a good stainless steel pan that I’d lightly oiled. This produced a light crust without overcooking the fish. The juice of 1 large lemon was enough to make a light pan sauce and I chose fresh tarragon and parsley for the herbs. Since basa was on sale, I used that.
A simple dish that made for a great meal. I’d certainly make this again.
This flounder recipe makes a nice, light, quick meal. Wonderful on a hot summer day. The crust was indeed crisp and brown and the fish tender and moist.
I used snapper instead of flounder and lightly dredged the fish with flour instead of dusting it. The pat of butter on top was a unique twist to the way I usually make fish and it added a richness not only to the finished sauce but also to the fish itself. I liked the tangy lemony sauce on its own and left out the herbs.
