Line a baking large enough to hold the salmon with parchment paper. Place the salmon in the center. With a paper towel, pat it dry. Let the salmon stand at room temperature while the oven preheats.
Place a rack in the center of your oven and preheat to 425°F.
Drizzle the salmon with the oil and honey. Top with Dijon, then sprinkle with the paprika and salt. With a pastry brush or your fingers, rub the salmon all over so that the topping ingredients mix and the salmon is nicely coated.
Bake the salmon uncovered until it is cooked through and flakes easily at the thickest part. The cooking time will vary based on the thickness of your salmon. Estimate 8 to 12 minutes for a thinner fillet (about 1/2 to 3/4 inch at the thickest part), 13 to 19 minutes for a thicker fillet (1-inch to 1 1/2-inches at the thickest part), or up to as long as 20 to 22 minutes for a very thick fillet (1 3/4 to 2 inches at the thickest part). You can also use an instant-read thermometer to test for doneness, removing the salmon when it reaches 145°F at the thickest part (I removed 5 degrees early, since the salmon will continue to cook as it rests). Let rest a few minutes, then slice crosswise into individual servings. Enjoy immediately.
