Can you roast garlic ahead of time and then re heat?

Answer 1

Yes of course you can.

Store roasted garlic in the refrigerator.

Answer 2

Yes, it is best when you use the broiler to reheat or a toaster oven.

I like to use the wet paper bag method that I think is a great way to reheat any loaf of bread, and a perfect way to make classic garlic bread. The evaporating water gives the loaf a burst of steam, which refreshes the interior (this type of bread tends toward the dry side). Then the bag dries out to let the crust crisp and brown.

Wrap the loaf, then wet the bag with a spray bottle.

Heat the oven to 400ºF. Make diagonal slices in a 1-pound loaf of bread at 3/4-inch intervals, stopping short of the bottom crust. Slather some of the garlic butter into each cut.

Slip the loaf back into the paper bag it came in (or use a torn paper grocery bag; avoid those with printing or plastic on them). Wet the entire bag with a spray bottle or a very fast pass under the faucet.

Pop the package into the oven until it smells of popcorn and the crust is crisp, 10 to 15 minutes.
