Ingredient Amounts: Using this method, you may roast as few or as many cloves of garlic as you want. The only limitation is that there must be a little space between the cloves on the sheet pan. (We usually roast them about a pound at a time.)
Preheat oven to 250°F (120°C).Line a heavy baking sheet with parchment or a silicone baking mat. We find that we like the outcome better on parchment; however, any practical difference is negligible.
In a small bowl, toss the garlic cloves in the avocado oil (or olive oil) to completely coat them.Spread the oiled garlic cloves evenly across the prepared baking tray.Lightly sprinkle garlic cloves with kosher salt.
Roast garlic cloves for 45-50 minutes, or until garlic cloves are golden brown.Note that cooking times may vary, depending upon the size and variety of your garlic. Start checking after about 35 minutes. Cloves should be caramel in colored and have a soft, creamy texture.
When the garlic cloves are done, remove them from oven and allow to cool completely.Store roasted garlic in an airtight container.
Notes
Prepeeled cloves (like the kind you can buy in bulk at Costco) seem to be more prone to browning more easily.Want deeper caramelization and a shorter roast time? Bump the oven to 300°F—but keep an eye on those cloves so they don’t go too far.
Storage
REFRIGERATOR: Once cooled, roasted garlic can be stored in an airtight container in the fridge for up to one week. If you'd like it to last longer:JARRED IN OIL: Roasted garlic cloves can be jarred in olive oil and stored in the refrigerator for up to three weeks.To do this, place the prepared roasted garlic cloves in a jar. Pour in olive oil, and then use a chopstick to nudge the cloves around and allow the oil to flow to the bottom of the jar.Place cooled roasted cloves in a clean glass jar and pour in olive oil until the cloves are fully submerged. Use a chopstick or small spoon to release air bubbles. Store in the refrigerator for up to three weeks.⚠️ Note:Never store garlic in oil at room temperature. Refrigeration is key for food safety.FREEZER: To freeze roasted garlic, spread cloves evenly on a sheet pan and place in the freezer for up to one hour.Place individual frozen garlic cloves in a jar or other airtight container and freeze. Frozen cloves will keep up to three months in the freezer.You can also mash roasted garlic cloves, portion them into ice cube trays, and freeze them that way. This allows you to use only as much as you need at one time, without exposing the rest.
