Before you start cooking, make sure you have all the necessary ingredients for this roasted salmon recipe. The ingredients you will need are:

  • 4 salmon fillets, skin on (about 6 ounces each)
  • 2 medium red bell peppers, thinly sliced
  • 1 large red onion, thinly sliced
  • 1 large orange, zest and juice
  • 3 tablespoons olive oil
  • 2 tablespoons honey
  • 2 tablespoons balsamic vinegar
  • 1 teaspoon fresh rosemary, finely chopped
  • Salt and pepper, to taste


To make this delicious roasted salmon dish, follow these simple steps.

Step 1: Preheat the oven

Preheat your oven to 400°F (200°C). This will ensure that the salmon and vegetables roast evenly and cook to perfection.

Step 2: Prepare the vegetables

Wash and thinly slice the red bell peppers and red onion. Set aside.

Step 3: Make the orange glaze

In a small bowl, combine the orange zest, orange juice, olive oil, honey, balsamic vinegar, and chopped rosemary. Mix well until the ingredients are fully incorporated. Season with salt and pepper, to taste.

Step 4: Season the salmon

Place the salmon fillets, skin-side down, on a baking sheet lined with parchment paper. Season the salmon with salt and pepper, to taste. Drizzle about half of the orange glaze over the salmon, making sure to coat the fillets evenly.

Step 5: Roast the salmon

Place the salmon in the preheated oven and roast for 10 minutes. While the salmon is roasting, toss the sliced red bell peppers and red onion in the remaining orange glaze.

Step 6: Add the vegetables

After the initial 10 minutes of roasting, remove the salmon from the oven and arrange the vegetables around the salmon on the baking sheet. Return the baking sheet to the oven and continue roasting for an additional 10-12 minutes, or until the salmon is cooked through and the vegetables are tender.

Step 7: Serve the dish

Once the salmon is fully cooked and the vegetables are tender, remove the baking sheet from the oven. Transfer the salmon and vegetables to a serving platter, drizzling any remaining glaze from the baking sheet over the dish. Serve immediately and enjoy!
