Flounder Fillets 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 griddle finish so the Flounder Fillets stays central instead of getting buried under the rest of the plate.

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

Trim and season the Flounder Fillets 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.
Keep the griddle hot and work fast so the pieces stay clean, browned, and tender.
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.

Keep the seasoning clean and let the cut set the pace. Leftovers keep best when cooled quickly and packed shallow; Louisiana meals built around Flounder Fillets are usually stronger on day one than after repeated reheats.
