Ingredients (serves 4)
- 4 salmon fillets (about 6 oz / 170 g each), skin on or off, as preferred
- 1 lb (approx. 450 g) asparagus, trimmed (tough ends removed)
- 2 tbsp olive oil, divided
- 3 garlic cloves, minced
- 1 lemon (zest and juice), plus extra wedges for serving
- 1 tbsp fresh parsley, chopped (or 1 tsp dried)
- 1 tsp kosher salt (adjust to taste)
- 1/2 tsp freshly ground black pepper
- 1/2 tsp smoked paprika or sweet paprika (optional)
- 1 tbsp melted butter (optional, for richer flavor)
Equipment
- Baking sheet or rimmed sheet pan (line with parchment or foil for easy cleanup)
- Small bowl for dressing
Step-by-step method
- Preheat and prep: Preheat oven to 400°F (200°C). Pat salmon dry with paper towels and let come to room temperature while you prep the asparagus.
- Season the asparagus: Toss trimmed asparagus with 1 tbsp olive oil, half the minced garlic, a pinch of salt and pepper. Spread asparagus in a single layer on one side of the baking sheet.
- Prepare the salmon: In a small bowl, combine 1 tbsp olive oil, remaining garlic, lemon zest, lemon juice from half the lemon, parsley, salt, pepper, and paprika (if using). Brush or spoon mixture over salmon fillets and place fillets skin-side down on the other side of the baking sheet. If using butter, brush a little melted butter over the salmon for extra richness.
- Bake: Transfer the sheet pan to the oven and bake 12–14 minutes, depending on thickness. Salmon is done when it flakes easily with a fork and reaches an internal temp of 125–130°F (52–55°C) for medium-rare to medium. Thicker fillets may need 15–18 minutes.
- Optional broil finish: For a slightly golden top, broil on high for 1–2 minutes — watch carefully to avoid burning.
- Serve: Squeeze remaining lemon half over salmon and asparagus, garnish with extra parsley, and serve immediately.
Cooking tips for perfectly tender baked salmon with asparagus
- Don’t overcook: Salmon continues to cook after removing from the oven. Aim for 125–130°F to keep it tender and flaky.
- Even thickness: If fillets vary in thickness, fold thinner ends under or start the thicker fillets a few minutes earlier.
- One-pan convenience: Arrange asparagus in a single layer and don’t overcrowd so it roasts, not steams.
- Flavor boosts: Add capers or a dollop of herb compound butter at the end, or sprinkle 1–2 tbsp grated Parmesan over asparagus before serving.
- Make it spicy: Add a pinch of crushed red pepper flakes or a drizzle of chili oil.
Variations and swaps
- Keto-friendly crust: Mix 2 tbsp almond flour with 1 tbsp grated Parmesan and press on top of the salmon before baking.
- Herb swap: Use dill, tarragon, or basil instead of parsley.
- Citrus twist: Replace lemon with lime or orange for a different citrus note.
- Substitute veggies: Broccoli, broccolini, or green beans work well if asparagus isn’t available.
Storage and reheating
- Refrigerate leftover salmon and asparagus within 2 hours in an airtight container for up to 3 days.
- Reheat gently in a 300°F (150°C) oven for 8–10 minutes or reheat the asparagus and salmon separately in a skillet to preserve texture. Cold salmon is also excellent chopped into salads.
