Preheat your oven to 425°F (220°C). This higher temperature will help achieve a crispier texture.
Trim and halve the Brussels sprouts. Make sure they are cut uniformly to ensure even cooking.
In a large bowl, toss the Brussels sprouts with melted coconut oil, dried thyme, dried oregano, garlic powder, onion powder (if using), smoked paprika (if using), and salt. Make sure each sprout is well-coated with oil and seasonings.
Arrange the Brussels sprouts in a single layer on a baking sheet. For extra crispiness, ensure they’re not overcrowded; use two baking sheets if necessary.
Roast in the preheated oven for 20-25 minutes, flipping halfway through, until the Brussels sprouts are deeply caramelized and crispy on the edges.
Remove from the oven and let cool slightly. Garnish with chopped fresh parsley before serving.
