Mediterranean Sea Bass en Papillote

by admin

I was treated to a delightful seafood lunch featuring a healthy, tasty Mediterranean Sea Bass en Papillote . With the Lenten season in full force, I knew I had to recreate this delicious dish at home.

Mediterranean Sea Bass en Papillote

The big question was if the picky hubby would eat more than a courtesy bite. I’d be happy to finish his portion, of course, but my fingers were crossed. After years of cooking French recipes from Dorie Greenspan’s cookbook, Around My French Table, I was quite comfortable cooking en papillote. And besides the questionable fish (at least for the one who questions any seafood that’s not in a tuna casserole), the ingredients were straight forward. All classic Mediterranean foods. The whole process is quite easy, I promise.

This recipe is courtesy of Chef Ryan Nelson of Late Harvest Kitchen, one of our favorite local restaurants. He hosted a lunch along with  the Seafood Nutrition Partnership and demonstrated how to cook seafood en papillote, which is cooking in a parchment envelope. Our first course was a salad of greens and tender salmon tossed in a Caesar dressing with a touch of tomato paste and hot sauce, then this lovely sea bass. We were pampered!

What Does en Papillote Mean?

Literally, papillote is the French term for the frilly paper used to decorate the rib bones on crown roasts, ends of lamb chops, etc. But the phrase en papillote refers to baking food inside a wrapping of parchment . Chef Ryan gave us some pre-made parchment envelopes that were slick to use. Otherwise, you can easily make a packet from a half sheet of parchment paper.

On occasion, Dorie instructed us to cook in foil as well as parchment, as it’s easier to seal.  If you’re concerned about having foil touch your food, you can always wrap it in parchment first, then foil. You’ll want to leave some room for the steam to expand, so you don’t need to seal the packets up too tightly.

How to Cook Mediterranean Sea Bass en Papillote

Since the ingredients inside the parchment basically steam while in the oven, the ingredients must be nicely seasoned as well as being flavorful themselves. This was the perfect recipe to showcase this French cooking method.

  • Season the Barramundi fillets, AKA Sea Bass, generously with salt and pepper, then top with capers, olives, tomatoes, and garlic after a quick saute and deglazing with wine. So many delicious layers of flavor!
  • Next, place the fish in the bag, top with lemon slices and thyme, then half or a third of the topping. Fold over the open end of the bag tightly two or three times. It can be secured with a stapler or paper clips if the folds aren’t secure.
  • Place the packets on a rimmed baking sheet and cook  at 400º for about 12 minutes.
  • Generally seafood is cooked for about 10 minutes/inch of thickness.
  • The packets can be brought to the table on dinner plate, then slit with a knife to open (do this carefully to avoid getting blasted with hot steam). A fun production especially for dinner guests.
  • Use your favorite mild, white fish for this recipe like cod, halibut, branzino, flounder, talapia, perch grouper have all been offered as substitutes. The barramundi is quite thin, so you may need to adjust your baking times.

P.S. Bill, AKA, the picky hubby, loved this dish. I’m slowly making progress expanding his seafood repertoire!
