Preparation of Tuna en Papillote
Take the tuna or tuna steak, clean it or have it cleaned at the fish market.
Place it on a sheet of parchment paper large enough to then close it easily.Add to the fish’s belly the lemon slice, parsley, garlic, rosemary, salt, pepper, and a drizzle of olive oil.
Close the parchment paper like a candy, sealing the sides well to retain steam during cooking. This way, during cooking, the steam released will stay inside the package, cooking it without drying it out.
Bake in a preheated oven at 400°F for about 30-35 minutes. The cooking depends on the size of the fish, so check the cooking by gently opening the package. If necessary, close it again and continue cooking.
Once cooked, you can serve the tuna en papillote on the plate with the parchment paper for a more scenic presentation, moreover, the liquid part it releases will ensure it doesn’t dry out quickly.
Useful Tips for Tuna en Papillote
Removing skin and bones: Once on the plate, the first thing I do is remove the skin from the fish, as once it cools it becomes difficult to remove, then I remove the bones, the central one that removes easily, the dorsal ones, and the ones underneath. VIDEO HOW TO REMOVE THE BONES
Serving with sauce: You can accompany the tuna with a light sauce, like mayonnaise or yogurt sauce, to add a touch of freshness.
Seasonal substitutes: You can enrich the tuna with other fresh herbs like thyme or marjoram. In summer, add fresh cherry tomatoes or grilled zucchini to the package for a richer dish.
Why choose parchment paper instead of aluminum?
Read the product label to see if it’s suitable for exposure to the oven with acidic foods such as lemon, tomato… Aluminum, being a metal, can accumulate in the body even in low doses and cause discomfort. To learn more, I refer you to this link of “Il fatto alimentare”.
Defrosting
If, like me, you had this fish frozen, I suggest thawing it slowly by placing it in the refrigerator several hours before, so it thaws correctly.
