Why Make Roasted Garlic with Whole Bulbs?

Roasting whole garlic bulbs gives you more roasted garlic for less work! And if you’re looking at this recipe, you probably already know:

• roasted garlic is super satisfying to squeeze out from the whole bulbs,
• it has a sweet and mellow flavor compared to fresh, pungent garlic, and
• roasted garlic is convenient to add directly into hummus or dips, sauces (like my Lemon Roasted Garlic Sauce), or even slathered directly on toast!

Classic Versus Oil-Free

Both methods make delicious, caramelized roasted garlic cloves that are soft and spreadable. However, there are differences so you might choose one based on the dishes you’re planning to make.

Classic Roasted Garlic with Oil makes

• silky soft texture that’s easy to spread
• richness from the oil for a creamier mouthfeel
• the oil carries oil-soluble flavors for more dimension

Oil-Free Roasted Garlic

• cuts down on the calories and fat
• you can still make it if you’re low on oil in the pantry
• is still soft and spreadable but not as silky as with oil
• missing some of the dimension of oil-roasted garlic but can be kicked up with acidic ingredients and salt

Notes

For all: ovens and air fryer temps can vary a bit so check on your garlic about 10 minutes before and gauge the exact time you need from there.

For AIR FRYERS: if you don't have a dish to fit, you can make a envelope with foil. Place the bulbs in a row in the middle of a sheet, Overlap the sides to cover, then roll up the short ends to seal.
