Parchment Packet Baked Tuna Steaks & Vegetables with Creamy Dijon-Turmeric Sauce


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.

4 packets


  • ¼ cup mayonnaise

  • 1 tablespoon chopped fresh parsley

  • 2 teaspoons Dijon mustard

  • 1 teaspoon honey

  • ½ teaspoon ground turmeric

  • 2 cups thinly sliced Yukon Gold potatoes (about 1/8-inch)

  • ½ teaspoon salt, divided

  • teaspoon ground pepper, plus 1/4 teaspoon, divided

  • 4 cups chopped kale

  • 1 ¼ pounds tuna (about 1 inch thick), cut into 4 pieces


  1. 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).

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

  3. 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.

  4. 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

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
