Instructions

1. Step 1: Remove salmon fillets from refrigerator 15 minutes before cooking to bring to room temperature. Pat completely dry with paper towels.

Chef’s Tips

• For perfectly crispy skin, ensure the salmon is completely dry before seasoning and don’t move it during the first sear – let the heat do the work.
• Use a meat thermometer to check doneness – internal temperature should reach 145°F (63°C) for medium, or 135°F (57°C) for medium-rare.
• If your cream sauce breaks or curdles, remove from heat immediately and whisk in a tablespoon of cold butter to bring it back together.

Spinach provides folate, iron, and vitamin K, while garlic offers immune-supporting compounds. This nutrient-dense meal supports ketosis while delivering essential vitamins and minerals your body needs to thrive.

Storage Instructions

Store leftover salmon in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat or in the microwave at 50% power to prevent overcooking. The cream sauce may separate slightly when reheated – simply stir in a tablespoon of fresh cream or butter to restore smoothness. For best quality, consume within 24 hours as fish is most delicious when fresh.
