01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper.
02 - Combine halved Brussels sprouts with olive oil, salt, and pepper in a large bowl, then spread evenly onto the prepared baking sheet, cut side down.
03 - Roast for 15 minutes, then turn the sprouts to ensure even caramelization.
04 - Whisk together maple syrup, soy sauce, minced garlic, rice vinegar, and optional red pepper flakes in a small mixing bowl.
05 - Drizzle the glaze over the Brussels sprouts, gently toss to coat, and continue roasting for an additional 7 to 10 minutes, until golden and crisp at the edges.
06 - Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente. Reserve 1/2 cup pasta water, then drain.
07 - In a large serving bowl or skillet, mix cooked pasta with roasted Brussels sprouts and any remaining glaze from the baking sheet. Toss together, adding reserved pasta water as necessary for desired consistency.
08 - Season to taste, adding additional salt or pepper if needed.
09 - Top with toasted sesame seeds, fresh herbs, and Parmesan or vegan cheese if preferred. Serve immediately.
