Preheat your oven to 400°F. Gently pat the salmon steaks dry with paper towels. Drizzle with olive oil and place them on a baking tray lined with parchment paper.
In a small bowl, whisk together the salt, black pepper, minced garlic, onion powder, and chili powder to create a flavorful spice blend. Rub this mixture onto both sides of the salmon steaks.
Slide the tray into the preheated oven and bake the salmon steaks for 12 minutes, just until they're cooked through and flaky, ensuring a moist and tender interior.
Remove the salmon from the oven and let it rest for 3 minutes. This allows the juices to redistribute, making each bite succulent. Garnish with fresh basil leaves for a pop of color and a hint of freshness.
