AIP / Paleo Oven Baked Cod Fish “En Papillote” with Spinach and Leeks

AIP / Paleo Cod Fish "En Papillote" with Spinash and Leeks / A Squirrel in the Kitchen

Pretty, delicious, and healthy, this oven baked cod fish “en papillote” is a feast for the eyes!  Yet another example that you can eat like a gourmet on the paleo autoimmune protocol!  I am particularly pleased with this new fish recipe; I had a great time preparing the dish and it was so much fun opening the little packages on our plates to discover the final result.

Cooking “en papillote” is a French cooking technique in which the food is wrapped up and sealed in parchment paper, allowing the ingredients to steam in their own flavorful liquids.  The final result is a delicate and aromatic dish with incredible savor.

AIP / Paleo Cod Fish "En Papillote" with Spinash and Leeks / A Squirrel in the KitchenHow to create a papillote? This video explains quite well the traditional technique to fold your parchment paper.  If, like me, you are not very skilled at origami and other paper folding techniques, you might want to adopt a simpler, no-nonsense approach.

Start by placing all your ingredients in the middle of a sheet of parchment paper.  Arrange everything in a pretty fashion, season, then gather up all sides of the paper to form a little package that you will close with some kitchen twine.  Voilà!

Substitutions? I was lucky to find some wild caught cod fish at Costco.  I only eat fish that has been wild caught, not farmed.  I have had several bad flare ups in the past when eating farmed fish; it has to do with the nature and quality of the feed they use.  Every time, I react badly.  But that’s my personal experience and you might not react the same way I do.  That being said, you can swap the cod for any kind of fish really: salmon, tilapia, trout, red snapper, mahi-mahi, …  You can’t go wrong and your dish will taste as good!

Author: Sophie

Cuisine: Paleo Autoimmune Protocol
Serves: 4
Ingredients
  • 4 fresh cod fish fillets (approx. 200 g or 0.45 lb per person)
  • 4 cups baby spinach
  • 2 cups finely sliced leeks (white and green parts)
  • 4 TBSP finely chopped Italian parsley
  • 2 TSP finely chopped garlic
  • 4 TSP extra-virgin olive oil
  • Fine sea salt, to taste
  • Lemon wedges for garnish.
Instructions
  1. Warm up the oven to 350 degree F.
  2. Cut out 4 pieces of parchment paper of approximately 15 x 20 inches.

  4. Gather up all sides of the parchment paper to form a package with the food inside. Tie a piece of kitchen twine around the neck of the package, as low as you can. Trim the excess of paper to 1 inch over the twine.

  8. Bon appétit!

      Delicious, nutritious, beautiful, and easy. My husband and I loved it! I will definitely make this recipe again and again with all kinds of fish. Can’t wait to try some more of your recipes! The show stopping Fruit Terrine next.
      PS – I saw you on the Autoimmune Connection panel this week. Excellent job. I was diagnosed with hypothyroidism 25 years ago when information was only available in medical libraries. I appreciate that you and others are willing to share your experiences and your talents in the kitchen.

        Hello Terri!
        Thanks for your kinds words. You can indeed replace the cod fish with any kind of fish really! There will be many more Autoimmune Connection episodes in the future 🙂 Awareness about thyroid disease and autoimmunity in general is spreading. Hopefully people won’t have to suffer as much with all the information available to them.
