Preheat and prep: Set your oven to broil on high and position a rack 6–8 inches from the heat source.
Line a sheet pan with foil for easy cleanup and lightly oil it.
Make the hot honey glaze: In a small bowl, whisk together honey, hot sauce or red pepper flakes, soy sauce, vinegar, Dijon, smoked paprika, and garlic. Taste and adjust the heat with more hot sauce if you like.
Season the salmon: Pat the fillets dry with paper towels. Rub with oil and sprinkle with salt and black pepper on both sides.
Glaze generously: Spoon about half of the glaze over the top of each fillet, coating the surface well while saving the rest for finishing.
Broil to caramelize: Broil for 5–7 minutes, depending on thickness.
The glaze should bubble and darken slightly at the edges. If your fillets are very thick, add 1–2 more minutes. Aim for an internal temperature of 125–130°F for medium and very tender results.
Finish with more glaze: Remove the pan and brush on the remaining glaze.
Let the salmon rest for 3 minutes so the juices redistribute.
Serve: Squeeze fresh lemon over the top and sprinkle with herbs if using. Pair with rice, roasted broccoli, or a crunchy slaw.
