When garlic is baked whole, it has a milder, sweeter flavor than raw garlic, making it a delicious accompaniment to beef, especially steak. If you’re a garlic fan, baked garlic is addictive; Nick and I can each eat a whole head. — Kerry Dunnington, Tasting the Seasons.
Preheat the oven to 400 degrees F.
Place the garlic halves on a rimmed baking sheet, facing the cut side up.
Drizzle some olive oil over the garlic and sprinkle with salt. Bake for about 10 minutes. Turn the halves over so the garlic side is facing down and bake an additional 10 minutes, or until fork-tender and lightly browned. Watch closely once the garlic begins to brown; it darkens quickly. Serve immediately.
