Creating the Texas Roadhouse Salmon Copycat is straightforward. Follow these steps for a delicious outcome:

1. Preheat the Grill: Preheat your grill to medium heat (about 350°F/175°C).
2. Prepare the Marinade: In a small bowl, whisk together olive oil, garlic powder, onion powder, paprika, brown sugar, salt, black pepper, and dried thyme.
3. Coat the Salmon: Rub the marinade generously over both sides of the salmon fillets.
4. Let it Rest: Allow the salmon to rest for about 10 minutes to absorb the flavors.
5. Grill the Salmon: Place the salmon fillets on the grill, skin side down. Grill for about 6-8 minutes without flipping, until the skin is crispy and the salmon is cooked through.
6. Check for Doneness: The salmon is done when it flakes easily with a fork. Aim for an internal temperature of 145°F (63°C).
7. Remove from Grill: Carefully transfer the salmon fillets from the grill to a serving platter.
8. Garnish: Squeeze fresh lemon juice over the top and garnish with chopped parsley, if desired.
9. Let it Rest: Allow the salmon to rest for about 5 minutes before serving to enhance the flavors.
10. Serve: Plate the salmon with your favorite sides for a complete meal.
