Why This Recipe Works
This baked salmon recipe is a win for several reasons:
- Moisture Locking: Cooking in foil keeps the salmon juicy and prevents it from drying out.
- Flavor Infusion: The lemon garlic butter seeps into both the fish and the asparagus.

- Balanced Nutrition: Omega-3-rich salmon, fiber-packed asparagus, and healthy fats from butter and olive oil make it both delicious and nourishing.
Ingredients
To serve four generous portions, you’ll need:
- 4 salmon fillets – fresh or previously frozen and thawed
- 1 bunch asparagus – woody ends trimmed for tenderness
- 4 tablespoons unsalted butter – melted, divided
- 4 cloves garlic – minced for a punch of flavor
- 2 tablespoons freshly squeezed lemon juice – for brightness
- 1 teaspoon lemon zest – adds an aromatic citrus note
- Salt – to taste
- Black pepper – to taste
- Fresh dill – for garnish and added freshness
Step-by-Step Instructions
Step 1 – Preheat the Oven
Preheat your oven to 375°F (190°C). This temperature ensures the salmon cooks evenly without drying out while still letting the asparagus become tender-crisp.
Step 2 – Prepare the Foil and Baking Sheet
Line a baking sheet with a large piece of aluminum foil. The foil needs to be big enough to fold over and seal the salmon and asparagus into a packet.
Step 3 – Arrange the Asparagus
Lay the asparagus spears in a single layer in the center of the foil. Drizzle with 1 tablespoon melted butter and season with salt and pepper. This pre-seasoning step helps the asparagus absorb flavor during baking.
Step 4 – Mix the Lemon Garlic Butter Sauce
In a small bowl, combine the minced garlic, lemon juice, and lemon zest. This zesty mixture will be the flavor powerhouse for both the salmon and vegetables.
Step 5 – Add the Salmon
Place the salmon fillets directly on top of the asparagus. Brush them generously with the remaining melted butter, ensuring each fillet is coated well. Season the salmon with salt and pepper to your liking.
Step 6 – Drizzle the Sauce
Pour the lemon garlic mixture evenly over each salmon fillet. This step allows the sauce to infuse the fish and asparagus during baking, creating a harmonious blend of flavors.
Step 7 – Seal the Foil Packet
Fold the sides of the foil over the salmon and asparagus, sealing tightly to form a packet. Leave a little air space inside for heat circulation, which helps with even cooking.
Step 8 – Bake the Salmon
Place the baking sheet in the preheated oven and bake for 15–20 minutes. Cooking time will depend on the thickness of your salmon fillets. The salmon is ready when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
Step 9 – Serve and Garnish
Carefully open the foil packet—watch out for steam—and garnish the salmon with fresh dill. Serve immediately for the best flavor and texture.
Serving Suggestions
Baked salmon in foil pairs well with:
- Herb-infused quinoa or wild rice
- Garlic mashed potatoes for a hearty option
- A light garden salad with olive oil dressing
- Crusty bread to soak up extra sauce
Tips for Perfect Baked Salmon in Foil
- Don’t Overcook – Salmon becomes dry if cooked too long. Check at the 15-minute mark.
- Use Fresh Ingredients – Fresh lemon, garlic, and herbs elevate the flavor.
- Try Olive Oil – For a lighter version, replace half the butter with extra virgin olive oil.
- Choose Evenly Sized Fillets – Ensures all pieces cook at the same rate.
- Double the Sauce – If you love extra flavor, make a little more lemon garlic butter to drizzle before serving.
- Grill Option – This recipe works beautifully on the grill for a smoky twist. Just place the foil packet over medium heat for 12–15 minutes.
