Salmon and vegetable en papillote

En papillote means cooking sealed in paper: the food cooks in its own steam, with no added fat. Salmon and vegetables en papillote give 33 g of protein for 275 kcal and 10 g of fat. The fish keeps all its tenderness and omega-3s, the vegetables their vitamins. A healthy, effortless cooking method.

At 275 kcal, en papillote is an ideal cutting or balance dish: plenty of protein and vegetables, few calories, the fat coming mostly from the salmon's omega-3s. For a heartier meal, serve it with rice or steamed potatoes. It is also easy to digest, perfect in the evening.

Cut the vegetables thin so they cook at the same speed as the fish. Lay them under the salmon fillet, add lemon, garlic and dill, seal the parchment (or foil) tightly and bake 15-20 minutes at 200 °C. The fold must be well sealed to trap the steam. Open it at the table: the aroma that escapes is part of the pleasure.

En papillote is a method more than a recipe: once you have the technique, you vary it endlessly. Follow the seasons for the vegetables — zucchini, tomato and pepper in summer, leek, carrot and fennel in winter — cutting them thin so they cook with the fish. Salmon swaps for cod, sea bream, trout, or even a thin chicken breast.

The aromatics set the dish's mood for zero calories: lemon and dill for the classic, ginger, soy sauce and sesame for an Asian note, tomato, olives and thyme for the Mediterranean. One parcel per person takes five minutes to prepare and cooks unattended — ideal for entertaining or for a healthy dinner on rushed evenings.

Salmon is only a starting point. Rainbow trout offers similar flesh that is slightly lighter, cod or pollock give a very lean version, and sea bream brings a more delicate note. Thickness matters more than species: a 2 cm fillet cooks in 15 to 18 minutes at 200 °C, while a thinner fillet can be ready in 12 minutes. When in doubt, the flesh should flake into large pieces with a fork and lose its translucent look in the centre.

For the vegetables, pick those that cook at the same speed as the fish: zucchini, pepper, cherry tomatoes, mushrooms, thin asparagus, very thin green beans, sliced fennel. Harder vegetables such as carrot or potato must be cut into very thin rounds or grated, otherwise they will stay crunchy while the fish is done. You can also par-cook them for two to three minutes in boiling water. For a more complete meal, serve the parcel with basmati rice, quinoa or steamed potatoes: count 150 to 200 g cooked per person depending on your carb needs.

Aromatics change everything without adding calories: lemon zest, parsley, chives, tarragon, thyme or fresh coriander. A teaspoon of wholegrain mustard or reduced-salt soy sauce adds character. If you want a little fat for flavour, a drizzle of about 5 g of olive oil per parcel adds 45 kcal, a decision to make according to your current goal.

The most common mistake is a badly sealed parcel: the steam escapes, the fish dries out and the vegetables roast instead of steaming. Fold the paper twice over itself along the edges and leave a little air inside so the parcel puffs up. A second mistake is vegetables that are too thick or too numerous, which release water and dilute the flavours. Stay at around 200 to 250 g of vegetables per person and cut them finely.

For safety and texture, do not cook longer than needed: overcooked salmon becomes dry and turns white on the surface. A fillet cooked through stays slightly pearly. Store leftovers in the fridge in a closed container and eat them within 24 hours; reheat gently in the oven or the microwave at low power. Cooked fish does not freeze ideally, but you can assemble the raw parcels ahead and keep them chilled for a few hours before baking.

To adapt the recipe to your goal, play on the side dish rather than the parcel itself. When cutting, keep it as is with a salad or extra green vegetables, for about 275 kcal per serving. When bulking, add a portion of rice, quinoa or whole-wheat pasta and a drizzle of olive oil, which easily takes the meal beyond 550 kcal. The 33 g protein base stays the same in both cases.
