Step 1

Turn the oven on to broil and position the rack in the upper third of the oven.

Step 2

Add the salmon fillets, flesh side up, to one side of a large baking dish. Add the zucchini to the other side. Drizzle the salmon and zucchini with the olive oil.

Step 3

Mix the soy sauce, maple syrup, ginger, rice vinegar, sriracha, cornstarch, garlic and whites of the onions in a small bowl; whisk until combined. Pour the sauce over the salmon and zucchini. Transfer to the broiler and cook for 7 minutes. Remove from the oven and spoon the sauce over the salmon, flipping the zucchini. Return the baking dish to the broiler and cook until the salmon has cooked through and the sauce has thickened, an additional 6 to 7 minutes.

Step 4

Add the rice to the bottom of a large platter, then top with the salmon. Add the zucchini to the platter. Spoon over the remaining sauce from the baking dish. Garnish with the reserved green onions. Serve.
