Preheat the Oven
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it with cooking spray.
Prepare the Salmon Marinade
In a small bowl, whisk together the olive oil, lemon juice, lemon zest, thyme, rosemary, garlic, salt, and black pepper.
Marinate the Salmon
Place the salmon fillets on the prepared baking sheet and spoon the marinade over the top of each fillet. Let the salmon marinate for at least 10-15 minutes.
Cook the Quinoa
While the salmon marinates, rinse the quinoa under cold water. In a medium pot, combine the quinoa, water or broth, and salt. Bring to a boil, then reduce the heat to low and cover. Let it simmer for 15-20 minutes, or until the quinoa is tender and the liquid is absorbed. Fluff the quinoa with a fork and set aside.
Bake the Salmon
Bake the salmon in the preheated oven for 12-15 minutes, or until the salmon easily flakes with a fork.
Serve
Divide the quinoa between serving plates and top with a salmon fillet. Garnish with extra lemon slices, fresh herbs, or a drizzle of olive oil if desired. Serve immediately and enjoy!
