In a large bowl, whisk together the sriracha, honey, lime juice, olive oil, kosher salt and black pepper.
Stir the brussels sprouts into the marinade.
Spread the sprouts across the preheated sheet pans.
Roast for 15-20 minutes until brown and crisp at the edges, using a spatula to flip and toss the sprouts about halfway through roasting
Season the brussels sprouts with flaky sea salt before serving.
Notes
Store leftovers in an airtight container in the refrigerator up to 4 days. Reheat them in a 350-degree F oven. Keep in mind that they won’t get back the crispness they had when you first roasted them. You can also eat leftovers cold as a salad.
