Pro Tips Before You Start

How to Make Cajun Grilled Salmon
Step 1 – Mix the spice rub
Combine cayenne pepper, smoked paprika, garlic granules, cumin, oregano, thyme, sea salt, black pepper, and brown sugar in a small bowl until evenly mixed.
Step 2 – Prep the salmon
Pat the salmon fillets dry with paper towels. Brush both sides lightly with olive oil.
Step 3 – Season generously
Coat all sides of the salmon with the spice blend, pressing gently so it sticks. Let rest at room temperature for 10 minutes.
Step 4 – Preheat the grill
Heat the grill to medium, about 375–400°F, and make sure the grates are clean.
Step 5 – Grill skin-side down
Place salmon skin-side down and cook for about 5 minutes without moving it to form a crust.
Step 6 – Flip and finish cooking
Carefully flip and cook another 4–5 minutes until the salmon is opaque and flakes easily with a fork.
What to Serve Them With
Serve with grilled vegetables or a fresh green salad for a balanced plate.
