I first made this sheet pan cod with spinach, tomatoes, and olives for a dinner with dear friends. I paired it with this Vietnamese-Style Shrimp Cocktail for a light and flavorful dinner.

You can pair this cod en papillote dish with rice, beans, or potatoes, or just save the calories for dessert!

There's so much to love about preparing fish en papillote. It's easy, you can layer flavors, and the fish stays super moist. Take some fish filets, layer some veggies and aromatics, add some seasonings, and then wrap it all up in parchment paper or foil. The paper or foil traps all of the essences of the seasonings and veggies and infuses them into the fish filets.

How to cook fish en papillote?
  1. Drop a dark leafy vegetable such as kale, spinach, chard, or collard greens on top of the parchment. You could also choose onions, chives, or leeks. 
  2. Add the fish filet of your choice, including cod, salmon, halibut, rockfish, or catfish. 
  3. Top the fish with aromatics, such as ginger, garlic, or herbs. 
  4. Add any veggies cut up into small pieces and drizzle with olive oil and season with salt, pepper, and herbs. 
  5. Wrap the fish packet and bake. How easy is that?!

P.S. While not traditional, I love using binder clips to seal the parchment paper for en papillote. They survive the oven nicely.
