Why make salmon in a parcel?

Cooking fish en papillote — sealed in paper parcels — is a classic French technique that produces incredibly moist, flavourful results with almost no effort. The steam trapped inside the parcel gently cooks the salmon while the butter, lemon zest and thyme infuse the vegetables below, creating a self-basting environment that requires no turning or monitoring.

Each person gets their own individual parcel, which makes for a wonderfully interactive serving moment at the table — opening a parcel to a rush of fragrant thyme and lemon steam is one of those small culinary pleasures that never gets old. It’s also a great technique for batch cooking or adjusting portions for different household members.

Ingredients (serves 4)

Servings4

Thyme butter

• 80 g butter, softened
• 1 tbsp lemon zest
• 2 tsp thyme leaves

Parcels

• 2 zucchini, thinly sliced diagonally
• 1 red onion, cut into wedges
• 1 bunch asparagus, woody ends trimmed
• 4 salmon fillets (approx. 150g each), skin on
• 2 long red chillies, halved lengthways (optional)

To serve

• 1 lemon, cut into wedges
• Fresh thyme sprigs

Tip: The thyme butter can be made up to 3 days ahead and stored in the fridge, or rolled in cling wrap and frozen for up to a month. Having it on hand means these parcels come together in minutes.

How to make thyme butter salmon parcels

Step 1: Preheat and make the thyme butter

Preheat oven to 200°C. Combine softened butter, lemon zest and thyme leaves in a small bowl. Season well with salt and pepper and mix until combined.

Step 2: Assemble the parcels

Cut four 30cm x 45cm pieces of baking paper and place on a clean work surface.

Divide the zucchini, red onion wedges and asparagus evenly among the four pieces of paper. Arrange one salmon fillet over the vegetable mixture on each. Top with sliced chilli if using, then divide the thyme butter evenly over each fillet. Season with salt and pepper.

Step 3: Seal and bake

Bring the two long sides of each piece of paper together at the centre and fold over twice to seal. Roll up the ends tightly to fully enclose the parcel. Place all four parcels on a baking tray.

Bake for 15 to 20 minutes or until the salmon is just cooked through.

Step 4: Serve

Divide the parcels among serving plates. Open at the table for the best presentation. Serve with lemon wedges and fresh thyme sprigs.

Tips for best results

• Make sure to seal the parcels tightly so no steam escapes during baking
• Slice the zucchini thinly on the diagonal so it cooks through in the same time as the salmon
• Use softened butter — it will spread more evenly over the salmon and melt into the vegetables faster
• Check the salmon at 15 minutes — thickness varies and you don’t want to overcook it
• Open the parcels carefully at the table as the steam inside will be hot
• The chilli is optional but adds a gentle warmth that works beautifully with the lemon and thyme

Serving suggestions

These thyme butter salmon parcels pair beautifully with:

• Steamed baby potatoes or crushed chat potatoes
• Warm crusty bread to soak up the butter sauce
• A simple green salad with lemon vinaigrette
• Steamed broccolini or green beans on the side
• A chilled glass of Chardonnay or Pinot Gris

Open them at the table for a theatrical touch — the rush of fragrant steam and the sight of perfectly cooked salmon and vegetables is a moment that never disappoints.
