Ingredients You’ll Need

Gather these pantry staples for 4 servings:

For the Salmon:

• 4 salmon fillets (6 oz each, skin-on or skinless; wild or farmed)
• 2 tbsp olive oil or avocado oil
• 2 tbsp Cajun seasoning (store-bought or homemade; see recipe below)
• Salt to taste (skip if your Cajun mix is salty)

For the Honey Butter Sauce:

• 4 tbsp unsalted butter
• 3 tbsp honey (or maple syrup for refined sugar-free)
• 2 cloves garlic, minced
• 1 tbsp low-sodium soy sauce or tamari (gluten-free)
• Juice of 1/2 lemon (about 1 tbsp)
• Optional: 1/4 tsp red pepper flakes for extra heat

Garnish:

• Chopped fresh parsley
• Lemon wedges
• Black or white sesame seeds

Homemade Cajun Seasoning (makes extra for storage):
Mix 2 tbsp paprika, 1 tbsp garlic powder, 1 tbsp onion powder, 1 tbsp dried oregano, 1 tsp cayenne, 1 tsp black pepper, 1 tsp thyme, 1/2 tsp salt. Store in a jar for 6 months.​

Step-by-Step Instructions

Pat salmon dry with paper towels for crispy edges and better seasoning adhesion.

Pan-Seared Method (15 minutes total):

1. Heat 2 tbsp oil in a large nonstick skillet over medium-high. Season salmon generously with Cajun mix.
2. Place skin-side up; sear 3 minutes until golden crust forms. Flip and cook 2 minutes.
3. Meanwhile, melt butter in a small pan. Stir in honey, garlic, soy sauce, and lemon juice; simmer 1-2 minutes until thickened.
4. Pour sauce over salmon. Spoon over fillets 3-5 minutes until internal temp hits 145°F (USDA safe; 125°F for medium-rare).​
5. Rest 2 minutes, garnish, and serve.

Baked Method (20 minutes total):

1. Preheat oven to 400°F. Line a sheet with parchment; pat and season salmon.
2. Rub with oil; bake skin-side down 7 minutes.
3. Whisk sauce as above; spoon over salmon. Bake 3-5 more minutes to 145°F.
4. Garnish and rest.

Air Fryer Method (12 minutes total):

1. Preheat air fryer to 400°F. Season salmon; spray basket.
2. Air fry 6 minutes skin-side down; flip, add sauce, and fry 4-6 minutes to 145°F.​

Expert Tips & Common Mistakes to Avoid

• Pat dry thoroughly: Excess moisture steams the fish instead of searing it.
• Use a thermometer: Aim for 145°F at thickest part for safety; wild salmon flakes at 120-125°F for optimal juiciness.
• Adjust spice: Start with 1.5 tbsp Cajun if sensitive; add flakes to sauce for heat.
• Don’t boil sauce: Gentle simmer prevents honey burn and keeps it glossy.
• Frozen salmon? Thaw fully in fridge overnight; pat extra dry.
• Make ahead: Prep sauce up to 2 days ahead; store in fridge.
