A quick and flavorful one-pan salmon dish featuring a lemon caper butter sauce, roasted asparagus, and cherry tomatoes. Perfect for busy weeknights and impresses with minimal effort.

Ingredients

Scale
  • 2 salmon fillets, skin-on, about 6 ounces each
  • 1 bunch asparagus, trimmed (about 1 pound)
  • 1 cup cherry tomatoes, halved
  • 3 tablespoons unsalted butter
  • 2 tablespoons capers, drained
  • Juice and zest of 1 medium lemon
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil
  • Salt and pepper to taste
  • 2 tablespoons fresh parsley, chopped (optional)

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Trim the woody ends off the asparagus (about 1-2 inches). Halve the cherry tomatoes if not pre-halved. Toss asparagus and tomatoes in a bowl with olive oil, salt, and pepper. Set aside.
  3. Pat the salmon dry with paper towels. Season both sides generously with salt and pepper.
  4. Heat a skillet on medium-high heat. Add 1 tablespoon butter and let it melt until foamy. Place salmon fillets skin-side down carefully into the pan. Sear for 3–4 minutes until the skin is crisp and releases easily.
  5. Flip the salmon gently using a spatula or tongs. Add the asparagus and tomatoes around the fish in the skillet. Transfer the skillet to the preheated oven.
  6. Roast for 8-10 minutes until salmon is opaque and flakes easily, asparagus is tender-crisp, and tomatoes are blistered.
  7. While roasting, melt the remaining 2 tablespoons butter in a small saucepan over low heat. Add minced garlic and cook for about 30 seconds until fragrant. Stir in lemon juice, lemon zest, and capers. Remove from heat.
  8. Remove skillet from oven carefully. Spoon the lemon caper butter sauce evenly over the salmon and veggies. Garnish with chopped fresh parsley if desired.
  9. Serve immediately.

Notes

Pat salmon dry to ensure crispy skin. Use room temperature butter for better sauce blending. If salmon is underdone, return to oven for a few minutes but watch closely to avoid drying out. For dairy-free, substitute butter with olive oil or plant-based margarine. If no oven-safe skillet, roast veggies separately and cook salmon on stovetop.
