Ingredients

Gather these 5 essentials for 4 servings (about 6 oz each fillet):

• 4 salmon fillets (skin-on or skinless, 1.5-2 lbs total), patted dry
• 2 tbsp olive oil
• 2 tbsp homemade Cajun seasoning (recipe below)
• 1 tsp brown sugar (for caramelization)
• Lemon wedges and fresh parsley, for serving

Homemade Cajun Seasoning (makes extra for storage):

• 2 tsp paprika (smoked for extra depth)
• 1 tsp garlic powder
• 1 tsp onion powder
• 1/2 tsp dried thyme (or oregano)
• 1/2 tsp black pepper
• 1/4 tsp cayenne (adjust for heat)
• 3/4 tsp kosher salt

Mix in a jar; store up to 6 months. This beats store-bought with fresh, vibrant taste.​

Step-by-Step Instructions

Follow these numbered steps for perfect results. Preheat oven to 425°F (220°C) while prepping.

1. Prep the foil: Line a baking sheet with foil. Crinkle it lightly with your hands, then unfold without smoothing – the wrinkles elevate salmon for even cooking and prevent sticking. Spray lightly with oil.​
2. Season salmon: Whisk olive oil, Cajun seasoning, and brown sugar into a paste. Rub evenly over fillets (flesh side if skin-on). Place skin-side down on foil, spaced apart for browning.
3. Bake: Roast 12-15 minutes until edges caramelize and center flakes easily (internal temp 125-145°F; 125°F for medium). Broil 1-2 minutes for crispier top if desired. Remove promptly to avoid overcooking.​
4. Rest and serve: Let sit 2 minutes. Squeeze lemon over top, garnish with parsley. No sauce needed, but try honey butter (1 tbsp softened butter + 1 tsp honey) brushed on post-bake for sweetness.​

Essential Cooking Tips

Master these for restaurant-quality salmon:

• Pat fillets dry to help seasoning stick and promote browning.
• Use a meat thermometer: 125°F for moist medium, 145°F for well-done per USDA.​
• Brown sugar aids caramelization without burning; skip for sugar-free.
• Skin-on protects moisture; remove after baking if preferred.
• For thicker fillets (1.5+ inches), add 2-3 minutes.
