Garlic is a pantry powerhouse that adds aromatic compounds and a punch of flavor to everything it touches. Roasting garlic transforms its pungent bite into a buttery, mellow ingredient that adds savory-sweet depth to everything from mashed potatoes to sauteed vegetables. It's also delicious as a spread or sandwich condiment.

There are several ways to make roasted garlic. Whole garlic cloves are sold in bulb-like heads covered in papery skin; peel back the outer layer and you’ll see that each bulb contains several individual cloves. (For more information, check out our primer, What Is a Clove of Garlic?.) To roast those whole heads of garlic, the prep couldn't be easier: you don’t have to peel a single clove. Plus, while you roast trimmed heads of garlic whole in the oven, each clove becomes creamy, caramelized and so soft, it just slips out of its skin. Alternatively, if you don't have a whole head on hand or are starting with peeled cloves, you can roast peeled individual garlic cloves; be sure to wrap them before putting them in the oven to develop a creamy, spreadable texture.

Here's everything you need to know about roasting garlic, including a step-by-step guide and recipes to put it to use.

How to Roast Garlic Bulbs

Slice about half an inch off the top of your whole garlic to expose the cloves.

Choose and Trim Your Garlic

Start with whole heads of garlic. The cloves should feel firm and the bulbs should be tightly closed with no brown spots. Avoid garlic that is sprouting. Peel away a few of the papery outer layers while keeping the bulb intact. Slice about 1/2 inch off the top, just enough to expose the cloves.

Season the Garlic

Place the garlic cut-side up on a piece of aluminum foil, then drizzle with olive oil and a sprinkle of kosher salt. If you like, add a few sprigs of fresh herbs.

Fold the foil over the garlic to make a packet, then roast it at 400 degrees for 45 minutes to an hour.

Fold Garlic In a Foil Packet

Fold the foil over the garlic and seal the edges tightly to make a packet.

Let the garlic cool, then squeeze the cloves out.

Roast Until Golden and Fragrant

Place the packet on a baking sheet and roast at 400 degrees F for 45 minutes to 1 hour. Remove the packet from the oven and let rest until cool enough to handle. The roasted garlic should be golden and caramelized, with tender cloves that have pulled away from the peel.

Squeeze It Out

Once cool, the cloves will easily squeeze out. Spread roasted garlic on toasted bread, mix it into mashed potatoes or soup, or toss with pasta. The garlicky possibilities are endless--and you didn't have to peel a single clove!

How Long to Roast Garlic

How long it takes to roast garlic depends on the size of the garlic bulb and the oven temperature. Our technique, as outlined above, takes heads of garlic 45 minutes to 1 hour to roast in a 400-degree F oven. Look for visual indicators: the garlic should be deeply golden and caramelized, and the cloves should have started pulling away from the peel. Once cooled, the cloves should easily squeeze out from their papery skins. Another tell-tale sign that your roasted garlic is done—your kitchen will smell like caramelized, toasty garlic goodness.

How to Roast Peeled Individual Garlic Cloves

If you're starting with peeled individual garlic cloves, preheat your oven to 400 degrees F while you prep. Place the garlic cloves in the center of a piece of foil and drizzle with olive oil (approximately 1 tablespoon for 8 cloves, depending on their size). Tightly seal the aluminum foil around the cloves to create a tight packet, then roast for 30-40 minutes, until the cloves are golden brown and tender.

How to Use Roasted Garlic

Roasted garlic can be used to add a mellow-sweet, savory depth to a variety of dishes, from sauces to mashed potatoes to soup. But first, garlic bread. Once you learn to roast your own garlic, you’ll never go back to store-bought again. Roast a whole head of garlic and then smush cloves onto broiled slices of crusty bread to make rustic Roasted Garlic Bruschetta, or spread the roasted garlic cloves on a baguette and bake with Parmesan and parsley to make Roasted Garlic Bread (pictured above). Mash roasted garlic to add to potato dishes, like these Roasted Garlic Mashed Potatoes or Roasted Garlic-Parmesan Mashed Potatoes, or this Vegan Roasted-Garlic Mashed Potatoes recipe. Use roasted garlic to flavor or thicken sauces and dressings, as with this maple-Dijon spiked Roasted Garlic Mustard, a roasted garlic aioli to accompany rack of lamb, or this game-day-ready Roasted Garlic-Bacon Dip. Make roasted garlic the star of your midday meal with Guy Fieri’s bold Roasted Garlic Soup.

Roasted Garlic Recipes

If you just need to roast one head of garlic, this is your recipe. Once you’ve trimmed the garlic, drizzle it with olive oil, seal it in a foil packet and roast for 20 to 30 minutes at 375 degrees F until the garlic is tender and soft.

Ree Drummond makes good use of time by roasting a big batch of garlic—to the tune of 8 bulbs. Heads of garlic are trimmed, drizzled with olive oil and sprinkled with salt and pepper, then roasted in a foil-covered pie pan in a 375-degree F oven for 45 minutes until the garlic is buttery soft.

If you’re short on time, turn to Katie Lee Biegel’s method for making roasted garlic in a microwave. While you might not get the same depth of caramelization, it’s a sure-fire shortcut to achieving roasted garlic’s trademark flavor.
