Whole Flounder with Cilantro and Onions

Louisiana cooking usually rewards patience, moisture control, and produce that can carry a little depth. This version uses Cilantro and Onions and a grilled whole fish finish so the Flounder Whole stays central instead of getting buried under the rest of the plate.

1 1/2 to 2 pounds Flounder Whole
Kosher salt
Black pepper
Neutral oil or rendered fat
1 handful Cilantro
1 to 2 cups Onions
Optional: 1 small Peppers
1 tablespoon oil

Trim and season the Flounder Whole while you prep the Cilantro and Onions.
Set up the pan, pot, or oven before you start cooking so the timing stays calm once the protein goes down.
Oil the fish well and leave it alone on the grate until it naturally releases.
Fold in the Cilantro and Onions at the right point so they support the cut instead of dissolving into the background.
Rest or hold the protein briefly, then serve while the pan juices or broth still feel connected to the plate.

If the skin sticks, the fish usually needs another minute before turning. Leftovers keep best when cooled quickly and packed shallow; Louisiana meals built around Flounder Whole are usually stronger on day one than after repeated reheats.
