In a large bowl, toss garlic with a generous amount of olive oil - enough to coat each clove.
Spread garlic cloves onto a foil lined baking sheet (I use the bottom of my broiling pan), then sprinkle with salt and pepper. Be sure to use a baking sheet that allows to the garlic cloves to be mostly single layer, but also fit snugly together.
Cover the baking sheet with foil, making sure you have a good seal over top and around the edges. Feel free to use multiple layers of foil if necessary to get a good seal.
Bake at 425 degrees for 45 minutes. Remove from oven and allow to cool (without removing foil) for about 15 minutes.
Remove foil and allow to cool to room temperature before placing in a freezer bag and freezing flat. (Make sure to taste test some on a toasted baguette first though!)
When you're ready to use, just break off as much as you want to thaw, then return the rest to the freezer!
