Cut broccoli into florets. Peel the stem using a vegetable peeler, trim the bottom and discard, then cut stem into 1-inch slices.
Place broccoli florets and stems, onion, potatoes and garlic onto a baking sheet. Toss vegetables with oil and ½ tsp each salt and pepper until coated and garlic is evenly dispersed. Bake 15 minutes.
Season salmon on both sides with remaining ¼ tsp each salt and pepper. Flip vegetables, add salmon to baking sheet, pushing vegetables to the sides. Bake 7 minutes. Turn oven to broil; broil until the vegetables are browned and the salmon is just cooked, 2 to 3 minutes. Don’t overcook that beautiful salmon! A touch of dark pink in the centre means it’s moist, tender and perfectly cooked.
Meanwhile, combine lemon zest and juice, olive oil and parsley in a small bowl. Serve salmon and vegetables drizzled with lemon-parsley sauce.
