Pat the salmon fillets completely dry with paper towels to ensure a good sear.

In a small bowl, combine the Cajun seasoning, olive oil, lemon juice, garlic powder, smoked paprika, salt, and pepper. Mix well to form a paste, then rub evenly over both sides of the salmon fillets.

Optional: Let the seasoned salmon marinate in the refrigerator for 15-30 minutes for enhanced flavor.

Heat a large skillet over medium-high heat. Add a tablespoon of olive oil and let it heat until it shimmers.

Carefully place the salmon fillets in the hot skillet, skin-side down if you left the skin on. Sear for 4-5 minutes without moving, until the skin is crispy and the salmon releases easily from the pan.

Flip the salmon gently and cook for another 3-4 minutes, or until the salmon flakes easily with a fork and reaches an internal temperature of 145°F.

While the salmon cooks, prepare the avocado lime crema. In a food processor or blender, combine the avocados, sour cream, lime juice, cilantro, garlic, salt, and cayenne pepper. Blend until smooth and creamy.

Add water, 1 tablespoon at a time, to the crema until it reaches your desired drizzle consistency.

Remove the salmon from the pan and let it rest for a minute. Serve with a generous drizzle of avocado lime crema over rice, in tacos, or alongside your favorite sides.
