Common Mistakes to Avoid

1. Overcooking the salmon — Start checking early because fillets vary in thickness.
2. Using very thick asparagus with thin salmon — The fish may finish before the asparagus becomes tender; choose similarly sized portions.
3. Sealing the foil too tightly against the fish — Leave a little space for steam to circulate.
4. Adding too much sauce — Excess liquid can cause the asparagus to steam rather than roast.

Required Equipment

• Rimmed baking sheet — Supports the foil packets and catches any accidental leaks.
• Heavy-duty aluminum foil — Creates a secure packet that retains moisture.
• Small mixing bowl — Makes combining the lemon-garlic sauce easy.
• Pastry brush or spoon — Spreads the sauce evenly over the salmon.
• Instant-read thermometer — Helps prevent overcooking and checks the salmon’s internal temperature.

Storage Instructions

Allow leftovers to cool and refrigerate them in an airtight glass or BPA-free food container within 2 hours of cooking.

The cooked salmon and asparagus will keep refrigerated for up to 3 days.

For best quality, freezing is possible for the salmon for up to 2 months, although the asparagus may become softer after thawing.

Reheat gently in a 160°C/325°F oven for 8–12 minutes or until warmed through. Avoid prolonged high heat because it can dry out the salmon.

📝 Ingredients

For the Salmon & Asparagus

• 4 salmon fillets, approximately 6 oz (170 g) each
• 1 lb (450 g) fresh asparagus, woody ends trimmed
• 1 tablespoon extra-virgin olive oil
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ½ teaspoon paprika, optional
• ½ teaspoon dried Italian herbs

Lemon Garlic Sauce

• 3 tablespoons unsalted butter, melted
• 1 tablespoon extra-virgin olive oil
• 4 cloves garlic, finely minced
• 2 tablespoons fresh lemon juice
• 1 teaspoon lemon zest
• 1 tablespoon fresh parsley, chopped
• ¼ teaspoon salt
• ⅛ teaspoon black pepper
• ¼ teaspoon red pepper flakes, optional

Ingredient notes: Choose salmon fillets of similar thickness so they cook at approximately the same rate. Fresh lemon juice gives the sauce a brighter flavor than bottled lemon juice.

Directions

1. Preheat the oven — 5 minutes
   Preheat to 200°C/400°F. Prepare four large sheets of heavy-duty foil on a baking sheet.
2. Prepare the asparagus — 3 minutes
   Trim the woody ends and arrange the asparagus evenly in the center of each foil sheet.
3. Season the salmon — 2 minutes
   Pat the salmon dry. Season both sides lightly with salt, black pepper, paprika, and Italian herbs. High-protein tip: Salmon is already protein-rich, so focus on keeping the fillet portion generous while using the sauce primarily for flavor.
4. Make the lemon-garlic sauce — 2 minutes
   In a small bowl, whisk melted butter, olive oil, garlic, lemon juice, lemon zest, parsley, salt, pepper, and red pepper flakes.
5. Assemble the packets — 3 minutes
   Place one salmon fillet over each portion of asparagus. Spoon the lemon-garlic sauce evenly over the salmon and asparagus.
6. Seal the foil — 2 minutes
   Fold the foil over the ingredients and seal the edges, leaving a little air space inside the packet. Tip: Do not wrap the foil so tightly that it presses against the salmon.
7. Bake — 15–20 minutes
   Place the packets on the baking sheet and bake at 200°C/400°F. Visual cue: The salmon should turn opaque and flake easily when gently pressed with a fork, while the asparagus should be bright green and tender-crisp.
8. Check doneness
   For food safety, salmon should reach 145°F/63°C at the thickest part.
9. Open carefully — 1 minute
   Carefully open the packets because hot steam will escape.
10. Finish and serve — 2 minutes
    Spoon the sauce from the packet over the salmon. Garnish with fresh parsley and additional lemon wedges.
