01 - Season salmon fillets on both sides with salt and pepper, pressing gently to adhere.
02 - In a small bowl, whisk together honey, soy sauce, garlic, lemon juice, and red pepper flakes (if using) until well combined.
03 - Heat olive oil in a large nonstick or cast iron skillet over medium-high heat until shimmering.
04 - Add salmon fillets skin-side up (or presentation-side down) to the hot pan. Sear without moving for 4-5 minutes until a golden crust forms.
05 - Flip salmon fillets carefully and add butter to the pan. Cook another 3-4 minutes until salmon is almost cooked through.
06 - Pour honey garlic sauce over the salmon. Let bubble and thicken, spooning sauce over fillets continuously, for 2-3 minutes until salmon is glazed and cooked to desired doneness.
07 - Remove from heat and transfer salmon to serving plates. Drizzle with remaining sauce from the pan.
08 - Sprinkle with chopped fresh parsley and serve with lemon wedges on the side.
