- Preheat your oven to 400 degrees F. Prepare each head of garlic by removing as much of the papery skin as you can while leaving the bulb intact. Cut across the cloves about 1/3 from the tip of the bulb so you expose a cross section of the cloves. Trim any cloves you miss with a paring knife.
- Place each bulb of garlic on a square sheet of foil. Drizzle olive oil over the exposed cloves on each bulb. Then wrap the bulbs tightly into individual foil balls.
- Place foil-wrapped garlic into a baking dish and bake for at least 30 minutes. Check one bulb. If the garlic is not yet golden brown and soft, put back in oven for another 10 minutes. Check again and repeat if needed. Once done, remove garlic from foil and you can easily scoop out the roasted cloves to eat or use in recipes.
