Pat the salmon fillets dry with paper towels to ensure crispy skin, then lightly season with salt and pepper.
Heat your skillet over medium-high heat until shimmering, then add a splash of vegetable oil and swirl to coat the bottom.
Place the salmon skin-side down in the hot skillet, pressing lightly to ensure contact. Cook for 4-5 minutes until the skin is golden and crispy, and the edges turn opaque.
Carefully flip the fillets with a fish spatula and cook for another 2-3 minutes, until the flesh is just opaque and flakes easily or reaches 52-54°C (125-130°F) on a thermometer.
Meanwhile, whisk together honey, soy sauce, lemon juice, minced garlic, and red pepper flakes in a small bowl until well combined.
Once the salmon is nearly cooked, reduce the heat slightly and pour the glaze over the fillets, spooning it over the top.
Allow the glaze to bubble and thicken for about a minute, coating the fish with a shiny, caramelized layer that smells sweet and spicy.
Remove the skillet from heat and let the salmon rest for 2 minutes to let the juices settle.
Serve the salmon hot, spooning extra glaze over the top for an extra shiny and flavorful finish.
