Set your oven to 450 degrees Fahrenheit and line a baking sheet with parchment paper.
In a small bowl, combine honey, whole grain mustard, smoked paprika, chipotle chili powder, onion powder, and garlic powder; whisk thoroughly.
Arrange the salmon fillets on the prepared baking sheet and season them with salt.
Generously spoon the honey mustard mixture over each salmon piece.
Bake the salmon for 10 to 12 minutes until it's thoroughly cooked.
For a nice caramelized finish, switch the oven to broil and place the salmon under the broiler for 1 to 2 minutes while keeping a close watch.
Garnish with fresh thyme and a sprinkle of flaky sea salt before serving warm. Enjoy your meal!
