How to Make Baked Salmon in Foil
Step 1: Prepare the Garlic Lemon Butter Sauce
Ingredients:
- 4 tablespoons unsalted butter (or 2 tbsp olive oil + 2 tbsp butter)
- 3 cloves garlic, minced
- 2 tablespoons fresh lemon juice
- 1/2 teaspoon lemon zest
- Salt and pepper to taste
Instructions:
- In a small saucepan, melt butter over low heat.
- Add garlic and cook for 1–2 minutes until fragrant (not browned).
- Stir in lemon juice, zest, salt, and pepper.
- Remove from heat and set aside.
Step 2: Prep the Salmon and Asparagus
- Preheat oven to 375°F (190°C).
- Trim ends off 1 bunch of asparagus (about 1 lb) and divide into 4 equal portions.
- Cut 4 pieces of foil (approx. 12” x 18” each).
- Place asparagus spears in the center of each foil sheet.
- Pat 4 salmon fillets dry and place one on top of each asparagus bed.
Step 3: Assemble Foil Packets
- Spoon garlic lemon butter sauce evenly over each salmon fillet.
- Add lemon slices and sprinkle with fresh herbs (optional).
- Bring the sides of the foil together and fold to seal tightly.
- Place foil packets on a baking sheet.
Step 4: Bake and Serve
- Bake for 18–20 minutes, depending on the thickness of the salmon.
- Carefully open packets (steam will escape).
- Serve hot with extra lemon wedges and a sprinkle of parsley or dill.
Tips for Perfect Baked Salmon
- Choose even-thickness fillets for uniform cooking.
- Don’t overbake—salmon is done when it flakes easily with a fork.
- Add wine or broth for extra moisture if baking longer.
- Let packets rest for 3 minutes before opening.
- Use a meat thermometer—internal temp should be 135–145°F.
