I appreciate how quickly this dish goes from prep to plate. The oven does most of the work, and I only need one pan, which makes cleanup easy. I enjoy how the lemon juice and zest brighten the rich salmon, while the butter keeps everything moist and flavorful. The asparagus roasts alongside the fish, making this a complete meal in one simple step. It’s light, fresh, and perfect for both weeknights and special occasions.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.)
1 pound Salmon cut into 2 Filets 1 bunch asparagus ends trimmed 6 tablespoons unsalted butter divided ½ teaspoon chili powder or paprika ½ teaspoon salt ½ teaspoon ground black pepper 3 tablespoons lemon juice 1 lemon, zested 1 teaspoon parsley chopped Lemon slices cooking spray
Directions
I begin by gathering all the ingredients and preheating the oven to 350°. I lightly spray a rimmed baking sheet with cooking spray.
I place the salmon on one end of the pan, slightly spaced apart, and arrange the trimmed asparagus on the other side. I pat the salmon dry with a paper towel to remove excess moisture.
Next, I melt 4 tablespoons of butter and drizzle it evenly over both the salmon and the asparagus. I sprinkle the chili powder (or paprika), salt, and black pepper over everything.
I drizzle the lemon juice over the salmon and asparagus and then sprinkle the lemon zest on top. I allow the salmon to sit with the lemon juice for about 5 minutes so the flavors can begin to absorb.
I divide the remaining butter into four small pieces and place a pat of butter on each end of the salmon filets. I top each with a slice of lemon or a little extra zest and sprinkle with chopped parsley.
I bake the salmon and asparagus for about 11 minutes. Once done, I remove the pan from the oven and let the salmon rest for 5 minutes before serving. I finish by sprinkling any remaining parsley over the top and serve it warm.
When I want to switch up the vegetables, I use broccoli, onions and peppers, cauliflower, or small diced potatoes instead of asparagus.
If I prefer a milder flavor, I use paprika instead of chili powder.
Sometimes I add minced garlic to the melted butter for extra depth.
For a slightly crispier top, I broil the salmon for the last 1–2 minutes, keeping a close eye on it so it doesn’t overcook.
Storage/Reheating
I store leftover salmon in an airtight container in the refrigerator for up to 3 days.
To reheat, I warm it gently in the oven at 300° until heated through, which helps keep it from drying out. I sometimes cover it loosely with foil to retain moisture.
If I’m short on time, I microwave it in short intervals, though I prefer the oven method for the best texture.
FAQs
How do I know when the salmon is done?
I look for the salmon to flake easily with a fork while remaining moist in the center.
Can I use frozen salmon?
I thaw it completely and pat it dry before baking for the best results.
What internal temperature should salmon reach?
I aim for an internal temperature of about 125–130°F before resting, allowing it to finish cooking as it sits.
Can I prepare this ahead of time?
I prep the ingredients and arrange them on the pan ahead of time, but I bake it just before serving for the freshest flavor.
Why shouldn’t I overbake salmon?
I find that salmon dries out quickly, so baking it just until done and letting it rest keeps it buttery and smooth.
Does the lemon juice cook the salmon?
I know that lemon juice is acidic and can begin to “cook” the fish slightly, but in this short time it mainly enhances flavor rather than fully cooking it.
Can I use dried parsley?
I can substitute dried parsley, though I use less since it’s more concentrated.
What can I serve with this dish?
I enjoy pairing it with rice, quinoa, or a simple side salad for a complete meal.
Can I make this dairy-free?
I replace the butter with a dairy-free alternative or olive oil when needed.
How do I prevent the asparagus from overcooking?
I trim thicker ends and choose evenly sized spears so they roast at the same rate as the salmon.
