- Sprouted garlic is safe to eat and can help reduce food waste if stored and used properly.
- Sprouting is a natural part of garlic's aging process and happens when it's exposed to light, moisture, or warmth.
- To avoid bitterness, remove the green shoot before cooking.
Garlic is one of those ingredients that always earns a spot on the grocery list because it appears in so many dishes. No matter how many lone cloves you have at home, it's easy to toss another bulb into your cart. However, garlic doesn't last forever. Like any fresh produce, it has a shelf life.
As garlic ages, it begins to sprout, sending a green shoot through its center. While it may look concerning, sprouted garlic is generally safe to use—unless you spot mold. To learn more about why garlic sprouts and whether it's safe to eat, we spoke with Dr. Keith Schneider, a professor and food scientist at the University of Florida Institute of Food and Agricultural Sciences. Ahead, we share his insight on why garlic sprouts, when it's safe to eat, and the signs that indicate it's time to toss it.

Why Does Garlic Sprout?
Garlic can sprout as a single clove or while the bulb remains intact and unused. Spotting a green shoot emerging from your garlic can feel alarming, but there's no need to panic.
The sprout signals that the garlic is aging, not that it has spoiled or gone bad, Schneider says. Garlic also sprouts in response to its environment. It often reacts to locations with too much light, moisture, or warmth, which are conditions commonly found in kitchens.
Is Sprouted Garlic Safe to Eat?
Sprouted garlic is a natural part of the aging process and its response to a new environment outside the soil. As long as it shows no signs of mold—such as blue-green discoloration or fuzzy patches—and has not been exposed to harmful bacteria, it's safe to eat, Schneider confirms. "Sprouting isn’t going to make garlic unsafe," he says.
While sprouted garlic is safe to consume, it can slightly change in flavor and affect the outcome of your dish. The green shoots produce a more bitter taste, similar to how sprouted onions become more bitter as they sprout. If you prefer a milder flavor, slice the clove in half and remove the green shoot before cooking. "If I see a sprout, I remove it," Schneider says. "I don’t want the increased bitterness in what I’m cooking."

When It's Time to Toss Sprouted Garlic
Like all fresh produce, garlic past its prime belongs in the trash to avoid the risk of foodborne illness. As garlic ages, it can develop mold, which appears as blue-green discoloration or fuzzy patches on the cloves. If you notice these signs—or any soft, shriveled, or rotten spots—discard the garlic immediately, according to Schneider.
After throwing it away, sanitize the area where you stored the garlic to remove any lingering mold spores or bacteria.
To reduce waste and save money, use up the bulbs in your current set before buying more. Avoid letting single cloves pile up in your kitchen, where they can age faster than you're able to use them. When you keep track of your fresh produce and store garlic in a cool, dry, dark place, you can minimize sprouting and keep your recipes from turning bitter.
