How to Make Buttery Baked Salmon & Asparagus
Step 1 – Preheat the oven
Preheat your oven to 425°F and line a baking sheet if desired for easier cleanup.
Step 2 – Prepare the foil packets
Cut two large pieces of foil, about 14×12 inches each, and place them on a flat surface.
Step 3 – Make the lemon butter mixture
In a small bowl, combine broth or white wine, lemon juice, garlic, hot sauce if using, and half of the butter cubes.
Step 4 – Assemble the packets
Place asparagus on each foil sheet and top with a salmon fillet, skin-side down. Season with salt and black pepper.
Step 5 – Add the toppings
Spoon the lemon butter mixture over the salmon. Add lemon slices and the remaining butter cubes on top.
Step 6 – Seal and bake
Fold the foil tightly into sealed packets and place on a baking sheet. Bake for 10–12 minutes until the salmon flakes easily with a fork.
Step 7 – Garnish and serve
Carefully open the packets to avoid steam burns. Garnish with chopped parsley and serve immediately.
What to Serve Them With
Serve with fluffy rice, mashed potatoes, or roasted baby potatoes.
A crisp green salad pairs perfectly with the buttery lemon flavors.
Warm crusty bread is great for soaking up the extra sauce.
Variations / Substitutions
Swap asparagus for green beans, broccoli, or zucchini.
Use olive oil instead of butter for a lighter option.
Add fresh dill or thyme for extra herb flavor.
Replace white wine with chicken broth if preferred.
Storage & Leftovers
Store leftovers in an airtight container in the refrigerator for up to 2 days.
Reheat gently in the oven or microwave until warmed through.
Freezing is not recommended as the asparagus may become soft after thawing.
