En papillote, also known as cooking “in a packet” is a fuss-free and flavorful way to cook seafood, says Sidoti, of Hello Fresh. “In traditional French en papillote cooking, food is sealed in parchment paper packets and baked. Flavors mingle and intensify as the steam conducts heat and gently cooks what’s inside,” Sidoti explained. “Not only is there little to no cleanup, but it also makes for a stunning presentation as the folds of the packet are opened up like a present to reveal an elegant and aromatic result.” In summer, swap out the parchment paper for foil, which is easier to seal tightly and also reseal if you need to take a quick peek at the fish during cooking. And don’t be afraid to throw veggies, citrus, spices, and herbs into the package to amp up the color and infuse even more flavor.”
