Ingredients Method Notes

Ingredients

  

• 2 salmon fillets (skin-on, ~170 g / 6 oz each)
• 1 tbsp olive oil
• 2 tbsp unsalted butter
• 2 garlic cloves, minced
• 1 tbsp fresh lemon juice
• 1 tsp lemon zest
• 1 tbsp fresh parsley, chopped
• Black pepper, to taste
• Salt, to taste

Method

 

1. Pat the salmon fillets dry thoroughly and season generously with salt and black pepper.
2. Heat olive oil in a non-stick or cast-iron skillet over medium-high heat.
3. Place salmon skin-side down and press gently for 10 seconds to prevent curling.
4. Cook for 5–6 minutes until the skin is golden and crispy.
5. Flip salmon and cook for another 2–3 minutes until just cooked through.
6. Reduce heat to medium. Add butter and minced garlic to the pan.
7. Once butter melts, stir in lemon juice and lemon zest.
8. Spoon the lemon butter sauce over the salmon for 30 seconds.
9. Remove from heat and garnish with fresh parsley before serving.

Notes

• Do not move the salmon while skin-side down, this ensures maximum crispiness.
• For extra richness, add 1 more tablespoon of butter at the end.
• Pairs well with zucchini noodles or sautéed spinach.
