For the best crisp skin, make sure the salmon is thoroughly dried and the pan is fully preheated before adding the fillets. If your salmon pieces are very thick, you can reduce the heat to medium low after the initial sear to finish cooking more gently and prevent drying out. Leftover salmon can be stored in an airtight container in the refrigerator for up to 3 days and is best reheated gently in a covered skillet over low heat with a small pat of butter to keep it moist. This recipe pairs well with sautéed spinach, roasted asparagus, or steamed broccoli for a complete keto meal that stays very low in net carbs.
