Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Arrange 1 bunch trimmed asparagus and 1 red and 1 yellow sliced bell pepper on a baking sheet, drizzle with 1 tbsp olive oil, and season with 1/4 tsp salt and 1/8 tsp black pepper. Toss to coat and spread in a single layer.
  2. Step 2: Place 2 salmon fillets skin-side down on top of the vegetables, brush with 1 tbsp olive oil, and sprinkle with 1 tsp chopped rosemary, 1 tsp chopped thyme, 1/4 tsp salt, and 1/8 tsp black pepper. Top each with 1/2 lemon slice.
  3. Step 3: Roast for 12-15 minutes until salmon is opaque and flakes easily with a fork, and vegetables are tender-crisp, checking at 12 minutes.

Frequently asked questions

How long does Herb-Roasted Salmon with Asparagus and Bell Peppers take to make?

Total time is about 30 minutes (15 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Herb-Roasted Salmon with Asparagus and Bell Peppers?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days. Freeze cooked fish (without fresh garnishes) for up to 3 months; thaw overnight in the fridge and reheat gently at 275°F until just warmed through to preserve texture.

Can I substitute ingredients in Herb-Roasted Salmon with Asparagus and Bell Peppers?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Herb-Roasted Salmon with Asparagus and Bell Peppers for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Herb-Roasted Salmon with Asparagus and Bell Peppers?

Skip grains, legumes, dairy and added sugar — none of them are Whole30-compliant. Tap "Plan a meal with the AI" to get specific side suggestions.
