Preheat Oven:: Set your oven to 400°F (200°C).
Trim Onions:: Trim just the root ends and tops so onions sit flat, leaving skins on.
Core & Season:: Cut a shallow X into the top of each onion. Place each onion on a square of heavy-duty foil. Sprinkle with salt and pepper.
Add Flavorings:: Press 1 tbsp butter, 1 sprig thyme, and 1 garlic clove into the cut top of each onion.
Wrap & Bake:: Wrap each onion tightly in foil and set on a baking sheet. Roast for 1 hour 10 minutes, until onions are very tender.
Finish & Serve:: Carefully unwrap, remove skins, and transfer to plates. Spoon over any melted butter from the foil and sprinkle with parsley if desired.
