Through the simple application of heat, raw garlic emerges soft and caramelized with a gentler flavor that borders on sweet. It’s truly like night and day.

Roasting garlic is easy and only requires a few minutes of hands-on time. The result is an incredible home cook’s tool for adding tons of flavor to literally anything, from soups to sauces. Each buttery-soft clove is perfect for spreading on a spare piece of sourdough bread or mashing into a salad dressing. As far as near-magical transformations go, roasted garlic should get a standing ovation.

Quick Overview

How to Roast a Whole Head of Garlic

  • Prepare garlic by removing any loose outer layers and slicing off the top.
  • Drizzle the exposed top with olive oil and wrap in aluminum foil.
  • Roast at 400ºF for 40 minutes until the cloves are completely soft.

How to Prepare Garlic for Roasting

Most of the work happens in the oven while you are sitting by casually reading a book or drinking a glass of wine. Here’s all you need to know.

  • Prepare the garlic. Use your fingers to peel away all the loose, papery outer layers. Leave the head itself intact with all the cloves connected. Trim about 1/4 inch off the top of the head of garlic to expose the tops of the garlic cloves.
  • Wrap in aluminum foil. Drizzle 1 to 2 teaspoons of olive oil over the exposed surface of the garlic, letting the oil sink down into the cloves, then wrap in foil.
  • Roast the garlic. It takes about 40 minutes in the oven. The garlic is done when a center clove is completely soft when pierced with a paring knife. Even once soft, you can continue roasting until deeply golden for a more caramelized flavor — check the garlic every 10 minutes. Let cool slightly, then press on the bottom of a clove to push it out of its paper.

How Long Do You Roast Garlic?

I’ve found that the exact cooking time and depth of color depend on several factors. Here are some pointers:

  • Generally, heads of garlic will roast to softness in about 45 minutes.
  • The size of the heads, the variety, and their age can affect the exact cooking time.
  • Start checking them around 40 minutes and continue cooking as long as you like — it’s very hard to overcook garlic!

Can You Freeze Roasted Garlic and How Long Does It Keep?

Roasted garlic can be refrigerated for up to two weekse or frozen for up to three months.

This is a particularly fine thing to do with older heads of garlic that have been languishing in the cupboard for a little too long, but you needn’t wait that long for your roasted garlic fix — fresh heads are just as tasty, if not more so!

How to Use Roasted Garlic

I recommend throwing a head of garlic in the oven whenever you’re making a slow-cooked braise or casserole. The soft cloves make an excellent appetizer while you’re waiting for your meal to be ready.

  • Spread on bread or crackers for a quick and easy appetizer.
  • Mash into salad dressing.
  • Mash into hummus, baba ganoush, or other spreads.
  • Use in place of raw garlic in soups, casseroles, and sauces.

  1. Heat the oven to 400°F. Arrange a rack in the middle of the oven and heat the oven to 400ºF.

  2. Peel (most of) the paper off the garlic. Use your fingers to peel away all the loose, papery, outer layers around the 1 or more heads of garlic. Leave the head(s) itself intact with all the cloves connected.

  3. Trim the top off the head of garlic. Trim about 1/4 inch off the top of the head(s) of garlic to expose the tops of the garlic cloves.

  4. Drizzle with olive oil. Drizzle 1 to 2 teaspoons olive oil over the exposed surface of the garlic, letting the oil sink down into the cloves.

  5. Wrap in foil and bake. Wrap the garlic in aluminum foil and roast in the oven for 40 minutes.

  6. Begin checking the garlic. After 40 minutes, begin checking the garlic. The garlic is done when a center clove is completely soft when pierced with a paring knife. Even once soft, you can continue roasting until deeply golden for a more caramelized flavor — check the garlic every 10 minutes. Exact roasting time will depend on the size of your garlic, the variety, and its age.

  7. Use or store the garlic. Let the garlic cool slightly, and then serve. Press on the bottom of a clove to push it out of its paper. Roasted garlic can also be refrigerated for up to 2 weeks or frozen for up to 3 months.

Recipe Notes

  • Speedy roasted garlic trick: While less visually stunning, separating the head of garlic into individual cloves will make the cloves roast more quickly. Leave the cloves intact and covered with their paper skin, toss with olive oil, and roast in a foil packet until soft.
