Step 1

Preheat the oven to 400° F. Wash and trim the ends of the Brussels sprouts. Remove any leaves from the outside that look wilted. Cut them in half. You may want to cut them into quarters if you have larger Brussels sprouts. Add them to a large bowl.

Step 2

In a small bowl, whisk together the soy sauce, dijon mustard, maple syrup, garlic, and red pepper flakes if using.

Step 3

Pour the soy glaze over the Brussels sprouts. Toss to evenly distribute.

Step 4

Line a rimmed baking sheet with aluminum foil or parchment paper. Evenly spread the Brussels sprouts on the baking sheet in a single layer.

Step 5

Bake in the oven for 15-20 minutes. Serve immediately.
