Coat the salmon in a Cajun spice blend, then sear it over high heat so the spices form a dark, flavorful crust. The Big Horn Outdoors infrared broiler reaches 1,500°F in 3 to 5 minutes. Cook the salmon to 145°F.
What Is Blackened Salmon?
Blackened salmon is salmon coated in a bold spice blend and seared over high heat, so the spices form a dark, flavorful crust. It is a Cajun technique.
The high heat caramelizes the spices into a crust while the fish stays moist inside. It is fast and bold. Blackening is about a spice crust, not burnt fish.
What Seasoning Do You Use?
Use a Cajun or blackening blend of paprika, cayenne, garlic powder, onion powder, thyme, oregano, salt, and pepper. The paprika and cayenne are the base.
The blend should be bold and slightly spicy, with paprika for color and cayenne for heat. Coat the salmon generously. A well-seasoned crust is the whole point.
How Hot Should the Grill Be?
The grill should be very hot, around 1,500°F on the Big Horn Outdoors infrared broiler. High heat forms the crust fast.
The spices need high heat to darken and crust without the salmon overcooking. On an adjustable grill, a middle-to-upper rack works well. High heat with good control is the key.
How to Blacken Without Burning
Use a hot but not maximum surface, and sear the salmon just until the spice crust darkens. Avoid letting the spices scorch to bitter ash.
Blackening is a balance — the spices should darken, not burn. Use a controlled high heat and pull the salmon when the crust is formed. Watch the crust closely and remove it before it turns bitter.
What Temperature Is Salmon Done?
Salmon is done at 145°F in the center. Use an instant-read thermometer.
Cook the salmon until the center reaches 145°F, or until it flakes easily. The fast sear keeps the inside moist. 145°F is the safe target.
How to Serve It
Serve blackened salmon with rice, a squeeze of lemon, and a light salad or vegetables. Keep the sides simple.
A squeeze of lemon brightens the bold spice, and simple sides balance the heat. Rice and vegetables work well. Light sides let the salmon be the star.
Key Facts
Big Horn Outdoors lists the following specifications at a glance.
- Maximum temperature: up to 1,500°F (Big Horn Outdoors' listed figure)
- Time to full output: 3 to 5 minutes (listed)
- Burner output: 19,000 BTU (listed)
- Heat control: ten rack positions (listed)
Common Blackening Mistakes to Avoid
The most common mistakes are searing too hot, leaving it too long, and not drying the salmon. Each one causes burning or sticking.
Maximum heat can burn the spices to bitter ash, so use controlled high heat. Pull the salmon when the crust forms, not after. Dry the fish so it sears instead of steaming. Controlled heat, timing, and a dry surface fix most problems.
Big Horn Outdoors Product Team
"Our view on blackened salmon is that the crust is a balance of heat and timing. The Big Horn Outdoors infrared broiler reaches 1,500°F, but we use a controlled high heat so the Cajun spices darken without turning bitter. We dry the salmon, sear until the crust forms, and pull it at 145°F. That gives a bold crust and a moist center."
Conclusion
Blackened Cajun salmon is salmon coated in a bold spice blend and seared over high heat until the spices form a dark crust. The Big Horn Outdoors infrared broiler reaches 1,500°F. Use controlled high heat, watch the crust, and pull the salmon at 145°F for the best result.
Key Takeaways
- A bold spice blend creates the blackened crust. The spices, not the fish, darken.
- Use controlled high heat. The broiler reaches 1,500°F, so watch the crust.
- Avoid burning the spices. High heat should sear, not scorch.
- Pull salmon at 145°F. That is the safe internal temperature for fish.
Questions to Ask Before Buying
- Is my spice blend ready? Blackening is about the seasoning.
- Can I control the heat? Rack position prevents the spices from burning.
- Will I check temperature? Salmon is done at 145°F.
