Preheat oven to 425° F, line a baking sheet with parchment paper, and set aside.
Clean and cut or snap off about 2 inches of the stem ends of the asparagus.
Arrange a single layer of asparagus onto the lined baking sheet.
In a small bowl, mix together, the oil, maple syrup, garlic, mustard, salt, and pepper.
Drizzle the sauce over the asparagus, and roll the vegetables so they are coated completely and evenly.
Place the baking sheet into the oven and bake for 10 to 15 minutes or until the asparagus is soft.
Once they are soft, remove from the oven and serve.
Serve these sweet and delicious Garlic Mustard Maple Asparagus as a side dish with any entree.
