Begin by preheating your oven to 400°F (200°C) to ensure it's hot enough for roasting.
In a large mixing bowl, combine the halved Brussels sprouts with olive oil, sea salt, and freshly ground black pepper. Use your hands or a spatula to toss the Brussels sprouts, ensuring they are fully coated with the oil and seasonings.
Line a baking sheet with parchment paper for easy cleanup and spread the coated Brussels sprouts out in a single layer on the sheet. Ensure they are not overcrowded to allow for even roasting.
Place the baking sheet in the preheated oven and roast the Brussels sprouts for 20-25 minutes. Check them halfway through; stir or shake the pan to ensure even cooking. They should turn crispy on the outside while remaining tender on the inside.
While your Brussels sprouts are roasting, prepare the honey Sriracha sauce. In a small mixing bowl, whisk together the honey, Sriracha sauce, apple cider vinegar, and minced garlic until the mixture is smooth and well combined. Set aside.
Once the Brussels sprouts are perfectly roasted, take them out of the oven and drizzle the homemade honey Sriracha sauce over them. Use a spatula to gently toss the sprouts in the sauce, ensuring even coverage.
Return the Brussels sprouts to the oven for an additional 5 minutes. This step allows the sauce to caramelize slightly, enhancing the flavors.
After the extra roasting time, remove the Brussels sprouts from the oven and carefully transfer them to a serving dish.
For a final touch, garnish your delicious dish with optional sesame seeds and finely sliced green onions before serving.
Notes
Serve in a decorative bowl or platter and drizzle any remaining sauce over the top for an enticing look.
