🛒 Ingredients

For the Salmon:

4 salmon fillets (6 oz each), skin-on
1 tsp sea salt
½ tsp black pepper
½ tsp garlic powder
1 tbsp olive oil or avocado oil

For the Lemon Butter Sauce:

4 tbsp unsalted butter
3 cloves garlic, minced
2 tbsp fresh lemon juice
1 tsp lemon zest
1 tbsp fresh parsley, finely chopped
Optional: pinch of red pepper flakes

🧑‍🍳 Step-by-Step Instructions

1️⃣ Pat the Salmon Dry

This is the secret to ultra-crispy skin.
Use paper towels to pat the salmon completely dry, especially the skin. Moisture prevents crisping.

Let the salmon sit at room temperature for 10–15 minutes before cooking. This helps it cook evenly.

2️⃣ Season Generously

Season both sides with salt, pepper, and garlic powder.
Focus on seasoning the flesh side well, but lightly season the skin side.

3️⃣ Heat the Pan Properly

Place a large skillet (preferably stainless steel or cast iron) over medium-high heat.
Add olive oil and let it heat until shimmering but not smoking.

To test: flick a drop of water into the pan—it should sizzle immediately.

4️⃣ Cook Skin-Side Down (Do Not Touch!)

Place salmon skin-side down in the hot pan.
Press gently with a spatula for 10 seconds to prevent curling.

Cook for 5–7 minutes without moving it.
You’ll see the color change from bottom to top as it cooks.

When ready, the skin will naturally release from the pan.

5️⃣ Flip & Finish

Flip carefully and cook the flesh side for another 2–3 minutes, depending on thickness.

For medium doneness, internal temperature should reach 125–130°F (52–54°C).
For well done, aim for 140°F (60°C).

Remove from pan and set aside.

🍋 Make the Lemon Butter Sauce

Lower heat to medium-low.

Add butter to the same pan.
Once melted, stir in minced garlic. Cook for 30 seconds (don’t brown it).
Add lemon juice and zest. Stir gently.
Finish with parsley and optional red pepper flakes.

Let it simmer for 1–2 minutes until slightly thickened.

🍽️ Serve

Spoon warm lemon butter over the salmon just before serving.

🔥 Pro Tips for Extra Crispy Skin

Always start with dry salmon.
Use a hot pan and don’t overcrowd it.
Resist the urge to flip too early.
Cast iron gives the best crust.
