For this rendition, we’re going with cod with a fresh n funky sauce made with basil, arugula, avocado, coconut aminos, and roasted pumpkin seeds (pepitas). Does it sound strange? It’s basically pesto without the parmesan and garlic…plus the coconut aminos. 

The sauce is sex. Just trust me on this one!

Let’s make it!

How to Make Cod in Parchment Paper:

Preheat the oven to 350 degrees F and line a baking sheet with parchment paper.

Begin by preparing the sauce. To do so, add all ingredients to a food processor or blender and blend until desired texture is reached…I make mine pretty smooth.

Lay the cod fillet on the parchment paper. Sprinkle with sea salt, spoon on a generous amount of sauce, and smooth it over the fillet until the whole thing is well-coated.

How to make fish en papillote

Fold the parchment paper over the cod, creating a packet. If needed, use twine to tie the ends together so that the packet remains closed. I’ve found the packet stays nice and snug as long as I crease the paper like a gift.

Bake in the preheated oven 20 to 30 minutes, until cooked through.

Serve with your favorite side dishes and an extra drizzle of sauce!

Recipe Adaptations:

  • If you have the time, marinate the fish in the sauce for 15 minutes to 8 hours ahead of time.
  • Use your favorite fish! Tilapia, salmon, and/or halibut work great.
  • Running low on time? Swap the sauce for your favorite store-bought or homemade pesto sauce.
  • Use arugula only or basil only for the sauce
  • Substitute regular liquid aminos or tamari for the coconut aminos
  • Add 1 clove of garlic to the sauce if you don’t follow a Low-FODMAP diet.
