Ingredients You’ll Need
Getting this recipe right is all about having the right, simple ingredients that each play an important role in flavor, texture, and presentation. From the rich butter to the bright lemon and fresh garlic, every element is essential to create the magic inside the foil packets.
- Salmon fillets (4, about 6 ounces each): Choose fresh, skin-on fillets for the best texture and flavor retention.
- Salt and freshly ground black pepper: Essential seasonings to enhance the natural taste of the fish and asparagus.
- Asparagus (1 pound, trimmed): Adds a crisp, green contrast that complements the richness of salmon beautifully.
- Lemon (1, sliced thinly): Brings brightness and tang with every bite and pairs perfectly with garlic butter.
- Unsalted butter (¼ cup, melted): Provides the silky base for the sauce, carrying garlic and lemon flavors.
- Garlic cloves (3, minced): Adds aromatic depth and a little zing to the dish.
- Fresh lemon juice (1 tablespoon): Intensifies the citrus notes, balancing the richness and lifting the overall flavor.
- Italian seasoning (2 teaspoons): A perfect herb mix that layers savory notes without overpowering.
- Fresh parsley (1 tablespoon, chopped, optional): For a fresh, herbaceous garnish that beautifies the finished dish.
How to Make Baked Salmon in Foil with Asparagus and Lemon Garlic Butter Sauce Recipe
Step 1: Preheat and Prepare Foil
Begin by preheating your oven to 375°F (190°C) to ensure it’s ready when your salmon packets are assembled. Preparing your aluminum foil sheets now will streamline the assembling process, making it smooth and fun. Aim for four large enough sheets to fold over and seal the packets securely, which locks in all the juices and flavors during baking.
Step 2: Season the Salmon
Place each salmon fillet in the center of a foil sheet with the oily side down. Don’t rush this step—season the fillets generously with salt and freshly ground black pepper. These simple seasonings let the natural flavor of the salmon shine and are the first step in building a profoundly delicious dish.
Step 3: Add Asparagus and Lemon
Next, divide the trimmed asparagus evenly among the four foil sheets, nesting it around each salmon fillet. Lay a few thin lemon slices on top of each piece of salmon. This layering not only looks beautiful when you serve but also infuses the fish and veggies with a fresh citrus aroma as it bakes.
Step 4: Make the Lemon Garlic Butter Sauce
In a small bowl, whisk together the melted butter, minced garlic, fresh lemon juice, and Italian seasoning. This sauce is the heart of the dish, combining richness, acidity, and herbaceous notes. Drizzle it evenly over each foil packet for that luscious, flavorful finish inside.
Step 5: Seal and Bake
Now fold the sides of the foil over the salmon and asparagus to form a well-sealed packet. This sealing is key—it keeps steam in, making the salmon perfectly tender and locking in every drop of the garlic butter sauce. Place these packets on a baking sheet and slide them into the preheated oven. Bake for 20-25 minutes, or until the salmon flakes easily with a fork.
Step 6: Garnish and Serve
When done, carefully open your foil packets—watch out for hot steam! Sprinkling chopped fresh parsley on top adds a pop of color and fresh flavor that brightens the entire dish.
How to Serve Baked Salmon in Foil with Asparagus and Lemon Garlic Butter Sauce Recipe

Garnishes
Fresh herbs like parsley or dill are truly delightful here. They introduce a fresh, mildly peppery note that cuts through the richness and adds visual appeal. A few thin lemon slices on top can provide an elegant finishing touch and extra zest when presented to guests.
Side Dishes
This dish pairs wonderfully with simple sides that let the salmon shine. Think garlic mashed potatoes, fluffy couscous, or a light quinoa salad. Steamed rice or a crusty slice of artisan bread can also soak up every bit of the luscious lemon garlic butter sauce perfectly.
Creative Ways to Present
For a rustic yet refined presentation, serve each salmon packet directly on a plate with the foil slightly peeled back, letting guests enjoy the reveal and aroma first-hand. Alternatively, flake the salmon atop a bed of lemony orzo or tucked inside lettuce wraps for a fun twist that’s both casual and sophisticated.
Make Ahead and Storage
Storing Leftovers
Leftover salmon in foil can be refrigerated in an airtight container for up to two days. Keep the asparagus with the salmon to maintain moisture and flavor balance. This makes for an easy next-day lunch or quick dinner option.
Freezing
If you want to prepare this recipe ahead of time, you can freeze the foil packets before baking. Simply wrap them tightly and place in a freezer-safe container. When ready to eat, thaw overnight in the refrigerator then bake as directed for perfect results.
Reheating
Reheat leftovers gently in the oven at 300°F (150°C) while still wrapped in foil to keep the fish moist and tender. Avoid microwaving if you want to preserve texture and flavor, but if pressed for time, brief microwave heating covered loosely with a microwave-safe lid can work as well.
FAQs
Can I use frozen salmon for this recipe?
Yes, but it’s best to thaw the salmon fully in the refrigerator before assembling the foil packets. Cooking salmon from frozen may result in uneven cooking and longer bake times.
What if I don’t have Italian seasoning?
No worries! You can substitute with a mix of dried basil, oregano, thyme, and rosemary for a similar herbal profile that complements the salmon beautifully.
Can I add other vegetables to this dish?
Absolutely! Thinly sliced zucchini, bell peppers, or cherry tomatoes can add both color and flavor. Just be mindful of the cooking time and slice veggies thinly to ensure even cooking.
How do I know when the salmon is perfectly cooked?
The salmon should flake easily with a fork but still be moist inside. It will appear opaque and slightly pink in the very center if you prefer it medium; otherwise, cook it through fully to your liking.
Is this recipe suitable for meal prep?
Definitely! The foil packets make it perfect for portion-controlled meals you can prepare ahead and reheat, making healthy and delicious eating effortless throughout the week.
