Preheat your oven to 400°F. This step is crucial as it ensures the asparagus roasts evenly, becoming tender and slightly crispy.
Arrange the asparagus in a single layer on a baking sheet. Make sure they aren’t crowded; this allows them to roast rather than steam.
Coat the asparagus with cooking spray or a drizzle of oil, ensuring each spear is lightly covered.
Sprinkle with kosher salt and black pepper. This simple seasoning lets the flavors shine.
Bake for 12 minutes or until the asparagus is tender. You’ll want to keep an eye on them; they should have a slight char but not be overly browned.
While the asparagus is roasting, melt butter in a small skillet over medium heat. Stir gently as it melts.
Cook the butter for about 3 minutes, allowing it to turn golden brown. You'll notice a nutty aroma developing; this is the key to achieving the perfect browned butter.
Remove the skillet from heat, and stir in soy sauce and balsamic vinegar. The mixture will bubble slightly, creating a beautiful sauce.
Once the asparagus is done roasting, drizzle the browned butter sauce over them. Toss gently to coat each spear well.
Serve immediately, enjoying the delightful combination of flavors and textures!
