What Is En Papillote Cooking?
"En papillote" might sound intimidatingly fancy, but don't let the French term fool you! It simply means "in paper" โ a cooking method where food is wrapped in parchment paper and baked.
The magic happens when the ingredients create steamโจ๏ธ inside their little paper pouches, infusing flavors and cooking everything to perfection.
Ingredients
Here's what you'll need for each packet:

- Cod fillet - Mild and flaky, perfect for soaking up bold flavors while staying tender when steamed. You can also use - halibut, tilapia, or salmon.
- Fresh ginger - Adds a warm, zesty kick and classic Asian aroma.
- Oyster sauce - Brings rich, savory umami and a hint of sweetness to the marinade. Use soy sauce if not available.
- Sesame oil -A little goes a long way for deep, nutty flavor and aroma.
- Fresh lime juice - Brightens the dish and balances the richness with fresh acidity.
- Garlic cloves - Adds bold, earthy flavor that complements the ginger and sauces.
- Olive oil - Helps keep the fish moist and carries all the flavors while cooking.
- Campari tomatoes- Adds freshness and color. Use cherry tomatoes.
- Fresh parsley
- Salt and pepper to taste
See recipe card for quantities.
Additions
- Veggies โ Thin carrots, zucchini, or baby bok choy steam beautifully.
- Herbs โ Top with scallions or fresh cilantro
Step by Step Instruction
- Preheat your oven to 400ยฐF (200ยฐC). Trust me, having the oven ready is key!
- Cut your parchment: For each serving, cut a piece of parchment paper about 15x15 inches. Fold it in half.

- Layer your ingredients: Open your parchment heart and place everything on one side.

- Seal the deal: Fold the empty half of the parchment over your ingredients. Starting at the top, make small, tight, overlapping folds along the open edge, crimping as you go to create a sealed packet.

- Transfer to baking sheet: Place your beautiful packets on a baking sheet. If making multiple servings, make sure they don't overlap.
- Bake for 12-15 minutes. The exact time depends on the thickness of your cod fillets โ thicker pieces may need an extra minute or two.
- Check for doneness: The parchment should puff up and brown slightly. The fish is done when it flakes easily with a fork and reaches an internal temperature of 145ยฐF.
- Serve immediately: Place each packet directly onto dinner plates.
Common Mistakes to Avoid
Even a technique this simple has a few pitfalls. Here's how to sidestep them:
- Leaky Packets: Make sure your crimping is tight! If steam escapes, you'll lose both flavor and the wow factor of the puffed packet.
- Undercooked Fish: Remember that thicker fillets need more time. When in doubt, give it an extra minute โ the parchment prevents overcooking better than other methods.
- Flavor Imbalance: The Asian flavors here work because they're in perfect harmony. Don't go overboard on the sesame oil or ginger, which can easily dominate.
Make-Ahead Tips
- While the actual cooking should happen just before serving, you can:
- Assemble the packets up to 4 hours before baking (keep refrigerated)
- Prepare the parchment hearts up to a day ahead
- Mix the Asian sauce up to 24 hours in advance
What to Serve with Cod En Papillote?
This dish is practically a complete meal in itself, but if you want to round things out:
- Simple sides: Steamed rice or quinoa soaks up all those amazing juices
- Fresh contrast: A crisp Asian slaw provides textural balance
- Extra veggies: Roasted bok choy or steamed broccoli complement the flavors beautifully
Pro Tips
Provide scissors โ๏ธ for easy opening, or slash the tops with a sharp knife just before serving. The "ooh" and "aah" moments are guaranteed!
Recipe FAQs
