Preheat your oven to 425°F (220°C) and line a large sheet pan with parchment paper or aluminum foil for easy cleanup.
In a small bowl, combine the olive oil, minced garlic, dried thyme, paprika, garlic powder, onion powder, salt and pepper. Mix well to create a marinade.
Place the salmon fillets on the sheet pan and brush the marinade over each fillet, ensuring they are evenly coated. Set aside to marinate while you prepare the vegetables.
Arrange the sweet potatoes and broccoli around the salmon fillets on the sheet pan, making sure they are in a single layer and not overlapping.
Place the sheet pan in the preheated oven and bake for about 15-20 minutes, or until the salmon is cooked through and flakes easily with a fork, and the sweet potatoes are tender. Cooking times may vary depending on the thickness of the salmon fillets, so adjust accordingly.
Once done, remove the sheet pan from the oven and allow it to cool for a few minutes. Serve the salmon with the roasted sweet potatoes and broccoli. Squeeze fresh lemon juice over the salmon fillets for added brightness and flavor.
Enjoy your delicious and healthy sheet pan salmon with sweet potatoes and broccoli!
