Oven Roasted Garlic Confit

When I make garlic confit, I treat it as a simple but serious technique: low heat, clean tools, and strict storage. The payoff is soft, jammy garlic and liquid gold oil that can quietly upgrade almost everything I cook.

You will need

  • 3 to 4 heads of fresh, firm garlic

  • Enough oil to fully cover the cloves (light olive oil, avocado oil, or a neutral oil)

  • Optional: a sprig of thyme or rosemary, a pinch of chili flakes, a bay leaf

Step by step

  1. Peel the cloves
    Peel 3 to 4 heads of garlic. Discard any cloves that are soft, bruised, or sprouting.

  2. Pack the pot
    Put the peeled cloves into your mini dutch oven. Add herbs or chili if you like. Pour in oil until every clove is completely submerged.

  3. Low oven, long time

    • Heat the oven to about 250°F (120°C).

    • Put the pot in the oven, uncovered or loosely covered.

    • Cook for about 2 hours, until the cloves are soft, pale golden, and mash easily with a spoon. They should not be dark brown or crispy.

  4. Cool and store
    Let it cool until warm, then transfer cloves and oil together to a clean, sterilized jar. Make sure the garlic stays fully covered with oil.

The safety rules you cannot skip

Garlic in oil is not like normal infused oil. It can become dangerous if stored the wrong way because of the risk of botulism.

So I follow three strict rules:

  1. Always refrigerate
    The jar goes into the fridge as soon as it is no longer hot. Never leave garlic confit at room temperature.

  2. Keep it clean
    Use clean utensils each time you scoop some out. Do not dip in bread or fingers.

  3. Use it quickly
    I plan to finish a jar within 1 to 2 weeks, or freeze portions in an ice cube tray for longer storage.

If anything smells off, looks strange, or you are unsure, throw it away.

How I actually use it

Here is where it earns its space in the fridge:

  • Mash a clove onto toast or fresh bread for instant garlic bread

  • Stir soft cloves into mashed potatoes or creamy soups

  • Blend a few cloves into hummus or white bean dip

  • Use the oil for salad dressings, sautéed vegetables, or drizzling over roasted meats and potatoes

A mini cast iron dutch oven is ideal for this recipe. It keeps the heat gentle and even, holds enough garlic to be worth the effort, and goes straight from oven to counter without fuss.
