Preheat your oven to 400°F (200°C).
Wash the Brussels sprouts and trim the ends.
Cut each sprout in half and place them in a large bowl.
Add olive oil, minced garlic, salt, and pepper to the bowl.
Toss the sprouts until they are evenly coated.
Spread the Brussels sprouts on a baking sheet in a single layer.
Roast in the oven for 20-25 minutes until golden brown.
Stir halfway through for even cooking.
Once roasted, remove from the oven and drizzle with lemon juice and zest.
Sprinkle with thyme and optional honey before serving.
