Tried different temperatures and times for roasted garlic just to see which gives the best results. Use it in almost every recipe or even slather it on toast like a spread!
Peel off the papery outer layers (skins) of the garlic bulb and cut about half an inch from the top (it will help you to squeeze out the roasted garlic cloves).
Place the garlic heads on a piece of foil, cut-side up. Drizzle with olive oil and wrap them well.
Bake at 400°F (205°C) for 1 hour to 1 hour 30 minutes, or until the cloves are browned and feel soft when pressed.
Let the garlic cool until easy to handle and squeeze out the garlic cloves into a jar (you can leave the garlic cloves whole or you can mash them with a fork). Cover with oil and store in the fridge for up to 2 weeks.

Notes
If you're only roasting garlic in the oven and not baking anything else at the same time, I suggest roasting more than one heads of garlic. Wrap each head of garlic separately or all the garlic heads together.
The good thing about this recipe is that you can check the garlic heads at any time and if you decide you want them more roasted you can return them in the oven and continue baking them until they reach your desired stage.
You can use foil or parchment paper to roast garlic. If using parchment paper, you will need to use 2 layers and secure the packets with kitchen twine.
