Flounder Fillets with Onions and Thyme

South Carolina cooking leans toward brighter finishes, lighter broth, and produce that keeps the plate moving. This version uses Onions and Thyme and a quick skillet 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 to 2 cups Onions
2 sprigs fresh Thyme
Optional: 1 small Garlic
1 tablespoon butter

Trim and season the Flounder Fillets while you prep the Onions and Thyme.
Set up the pan, pot, or oven before you start cooking so the timing stays calm once the protein goes down.
Keep the pan lively and stop cooking while the texture still feels deliberate.
Fold in the Onions and Thyme 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 pan feels crowded, split the batch and keep the browning clean. Leftovers keep best when cooled quickly and packed shallow; South Carolina meals built around Flounder Fillets are usually stronger on day one than after repeated reheats.
