Gingered Flounder in Parchment

Gingered flounder in parchment is the French en papillote technique steered toward Asian flavors. Delicate flounder fillets briefly marinate in a tangy mix of soy sauce, olive oil, garlic, and freshly grated ginger, then bake sealed inside heart-shaped parchment packets with julienned snow peas, red bell pepper, carrots, and scallions.

The steam trapped inside the packet does all the cooking work. Fish steams in its own juices and the vegetables wilt just enough to stay vibrant, all in 15 to 20 minutes. The result is a one-packet meal that arrives at the table puffed and dramatic, with all the marinade pooled inside as built-in sauce.

Cutting the parchment in a heart shape isn’t just aesthetic, it’s structural. The shape lets you pleat the edges tight from rounded top down to the point, sealing all the way around.

Chef Tips

• Pleat the edges firmly with overlapping folds, not just rolls. Loose seals let steam escape and the fish ends up dry instead of poached.
• Cut vegetables thin and uniform. Thick carrots stay crunchy while thinly sliced ones cook in time with the fish.
• Use parchment over foil if possible. Parchment puffs dramatically when served at the table, foil packets are flatter and lack that wow factor.
• Test doneness by carefully cutting one packet open. The fish should flake easily but still look just barely set in the center.

Variations

• Swap flounder for tilapia, sole, or salmon fillets, adjusting cook time for thicker cuts.
• Add a splash of mirin or rice vinegar to the marinade for sweet-tangy depth.
• Use baby bok choy or shredded cabbage in place of the snow peas for variety.
