Sprouted garlic is a common sight in kitchens, but many cooks wonder if those green shoots signal a safety issue. Experts confirm that sprouted garlic is generally safe to eat, although it can affect the taste. The key is knowing when sprouting is harmless aging versus actual spoilage.
What Causes Garlic to Sprout?
Garlic sprouts because it’s a living plant, and under the right conditions—excess moisture, heat, or light—it will attempt to grow. As registered dietitian Lizzy Swick explains, “The fact that it sprouts is actually a good thing; it means the garlic is still viable.” The green shoot is simply the beginning of a new plant stem.
Is Sprouted Garlic Safe?
Yes, as long as there are no signs of spoilage. A green sprout itself doesn’t make garlic toxic. Research even suggests that sprouting may increase certain antioxidant levels. However, if the garlic is soft, mushy, slimy, or has an off-putting odor, it should be discarded. These are indicators of bacterial or mold growth—not just aging.
How Does Sprouting Change the Flavor?
Sprouted garlic tends to become more bitter and sharper in flavor, especially in the green shoot. This bitterness is most noticeable in raw applications like salad dressings or pesto. Cooking can mellow the taste, but if you prefer a milder flavor, removing the green center before use is recommended.
When to Discard Sprouted Garlic: Red Flags
While sprouting isn’t dangerous, certain signs indicate the garlic has gone bad:
- Mold or fuzz: Visible mold growth on the cloves.
- Mushy texture: Soft, slimy, or collapsed cloves.
- Foul smell: A sour or rotten odor.
These aren’t just signs of aging; they mean the garlic may contain harmful bacteria or mold.
How to Prevent Garlic from Sprouting
Proper storage can slow down sprouting: keep garlic in a cool, dry, dark place with good ventilation. Avoid storing it in airtight containers that trap moisture.
Ultimately, sprouted garlic is safe as long as it remains firm and free of spoilage signs. The sprout itself doesn’t pose a health risk, but flavor may be affected. Discard only when clear signs of decay are present.
