Step-by-Step Instructions

1. Preheat Oven and Prepare Pan

Preheat oven to 200°C (400°F). Line a large baking sheet with parchment paper or foil.

2. Season Salmon

Pat salmon fillets dry with paper towels. Rub both sides with Cajun seasoning and a pinch of salt and pepper.

3. Prepare Vegetables

In a large bowl, toss bell peppers, zucchini, broccoli, and onion with olive oil, garlic, salt, pepper, and a pinch of Cajun seasoning. Spread vegetables in a single layer on the sheet pan.

4. Add Salmon to Sheet Pan

Place salmon fillets on the sheet pan among the vegetables. Make sure fillets are skin-side down if using skin-on salmon.

5. Roast in Oven

Bake 12–15 minutes, until salmon flakes easily with a fork and vegetables are tender and lightly caramelized. For extra browning, broil for 1–2 minutes at the end.

6. Serve and Garnish

Transfer salmon and vegetables to a serving platter. Garnish with fresh parsley and serve with lemon wedges. Pair with rice, quinoa, or a light salad for a complete meal.
