Step 1: Preheat your oven to 425°F (220°C) for that perfect crispy texture.
Step 2: Wash and chop the cauliflower into bite-sized florets and place in a large mixing bowl.
Step 3: In a separate bowl, whisk together the soy sauce, maple syrup, rice vinegar, garlic, sesame oil, and ginger.
Step 4: Pour the sauce over the cauliflower and toss until well-coated.
Step 5: Spread the cauliflower on a baking sheet lined with parchment paper and bake for 25-30 minutes, flipping halfway.
Step 6: In a saucepan, combine cornstarch and water, heat until bubbling and thickened, about 5-7 minutes.
Step 7: Once cauliflower is roasted, pour the thickened sauce over and toss gently. Serve hot garnished with sesame seeds and scallions.
