How to bake fish perfectly? Wrapping the fish and vegetables in parchment packets creates steam that keeps the tuna moist while it cooks. Plus, it's a fun presentation.

Ingredient Checklist


Instructions Checklist
  • Preheat oven to 450 degrees F. Cut 4 large sheets of parchment paper, each about 16 by 12 inches (or use pre-cut parchment sheets).

  • Combine mayonnaise, parsley, mustard, honey and turmeric in a small bowl.

  • To make packets, lay the parchment sheets on a work surface with the long sides closest to you. Fold each in half (bringing the short sides together), then open. Place 1/2 cup potatoes on one side of each piece of parchment and sprinkle with 1/4 teaspoon salt and 1/8 teaspoon pepper. Top each with 1 cup of kale and a piece of tuna. Sprinkle the tuna with the remaining 1/4 teaspoon each salt and pepper. Brush with the mayonnaise mixture. Close the packets and seal the edges with small, tight folds. Place the packets on a large baking sheet.

  • Bake until the fish is just cooked through, 10 to 15 minutes. (Carefully open one packet to check for doneness--be cautious of the steam.) Set each packet on its own plate. Let stand for 3 minutes. Cut an X in the top of each packet with scissors and carefully fold open to serve.


Equipment: Parchment paper or pre-cut parchment sheets

This was so easy and turned out very well. It is a new favorite way to have tuna. Love the mustard topping. Used low fat mayo and Greek yogurt mix. The fish was very good in about 10-12 minutes and I probably could have gone less. Fish was moist and flavorful. Read More

We like our tuna on the medium rare side and even cooking the packets 18 minutes the fish was undercooked and the potatoes were still raw. I cooked another 5 minutes until the tuna was to our taste but the potatoes weren't cooked. Read More

Loved this recipe. I actually used CURRY POWDER instead of turmeric as I was out and it was SO delicious! I was worried about the lack of oil/butter in order to cook the potatoes and kale but it turned out just fine. I halved the recipe and baked two packets in the toaster oven which I believe caused the kale to be a little crispier than intended but still super yummy! Read More
