Step 1

Preheat the oven to 400°F.

Step 2

Remove the papery skins from the outside of the garlic heads (do not separate the cloves). Slice the pointed tops from the heads, creating a flat surface exposing the cloves.

Step 3

Cut four square sheets of aluminum foil. Place one head of garlic cut side up in the center of each sheet.

Step 4

Drizzle the heads of garlic evenly with the olive oil and sprinkle with the salt.

Step 5

Wrap the aluminum foil tightly around each head of garlic. Place the heads on a baking sheet.

Step 6

Roast the garlic on middle rack of oven until a toothpick easily pierces the cloves, 45-50 minutes.

Step 7

Check to see that garlic is done. Remove from oven or add time as needed.

Step 8

Allow garlic to cool for at least 20 minutes. Once garlic is cool enough to handle, unwrap the heads. Serve whole, or squeeze the roasted cloves from their skins into a bowl.
