Ingredients You’ll Need

1 bunch fresh asparagus, trimmed
Salt and black pepper, to taste
1 tablespoon olive oil

4 tablespoons unsalted butter, melted
3–4 garlic cloves, minced
Zest of 1 lemon
Juice of 1 lemon
1 teaspoon Italian seasoning (optional)
Fresh parsley or dill, chopped (for garnish)
Step-by-Step Instructions
🔥 Step 1: Preheat and Prep
Preheat your oven to 400°F (200°C). Line a baking sheet with large sheets of aluminum foil—one for each salmon fillet.
🥬 Step 2: Arrange Asparagus
Place asparagus in the center of each foil sheet. Drizzle lightly with olive oil and season with salt and pepper.
🐟 Step 3: Add the Salmon
Lay a salmon fillet on top of the asparagus. Season the salmon with salt and black pepper.
🧄 Step 4: Make the Lemon Garlic Butter
In a small bowl, mix melted butter, minced garlic, lemon zest, lemon juice, and Italian seasoning.
🍋 Step 5: Sauce It Up
Spoon the lemon garlic butter sauce generously over each salmon fillet and asparagus bundle.
📦 Step 6: Seal the Foil
Fold the foil over the salmon and asparagus, sealing the edges tightly to create a packet.
⏱️ Step 7: Bake
Bake for 15–18 minutes, depending on thickness. Carefully open the foil and broil for 2–3 minutes if you prefer a lightly golden top.
How to Know When Salmon Is Done
Perfectly baked salmon should:
