Potatoes are a cornerstone of any kitchen. From crispy fries to velvety mashed potatoes, they’re a beloved ingredient with endless possibilities. But let’s face it—raw potatoes are often caked in dirt, leaving us to wonder: Do you really need to wash them if you’re going to peel them anyway? The answer is a resounding yes, and here’s why.
The Importance of Washing Produce
It’s easy to overlook washing foods with tough peels or skins. After all, isn’t the peel there to protect what’s inside? Not entirely. Fresh produce can harbor bacteria, pesticides, and dirt from its journey through soil, storage, and transportation. According to the FDA, rinsing fruits and vegetables before preparation can prevent harmful bacteria from transferring from the outer surface to the edible parts via your knife, peeler, or cutting board.
This is especially important for potatoes, which are dug straight from the earth. The soil clinging to their skin isn’t just dirt—it’s a potential carrier of bacteria and chemicals that could make you sick.
Why Potatoes Deserve Extra Attention
Potatoes are a special case because they’re root vegetables, meaning they grow underground and have direct contact with soil throughout their life. Even if you’re peeling them, washing potatoes before preparation is crucial.
As Chef Catt Fields White explains, “Potatoes grow in soil that may contain bacteria, pesticides, and debris. Washing them thoroughly before cooking ensures these contaminants don’t end up in your dish.”
For recipes where the skin stays on, like baked or roasted potatoes, cleaning becomes even more essential. A good scrub not only removes dirt but also eliminates harmful residues, ensuring every bite is as safe as it is delicious.
The Best Way to Wash Your Potatoes
Washing potatoes doesn’t have to be complicated. Here’s how to do it right:
- Rinse Under Running Water: Hold each potato under cool running water and use your hands or a vegetable brush to scrub away visible dirt. No soap needed!
- For Large Batches: Submerge multiple potatoes in a bowl of cold water for 20-30 minutes. Stir occasionally to loosen dirt, then rinse each potato individually.
- Skip the Chemicals: Never use soap, bleach, or disinfectants to clean your potatoes. These substances can leave harmful residues that linger even after rinsing.
Prepping Potatoes in Advance
Want to get a head start on dinner? Once your potatoes are washed, peeled, and chopped, you can keep them fresh by placing them in a bowl of cold water. Fully submerge the pieces to prevent browning, and if you’re not using them right away, store the bowl in the fridge with an airtight cover. Just be sure to cook them within 24 hours for the best flavor and texture.
A Note on Storage
While washing is vital before cooking, it’s a no-go when storing potatoes. Washing them before storing can lead to moisture buildup, encouraging rot and mold. Instead, store your unwashed potatoes in a cool, dark, and well-ventilated spot. Avoid plastic bags and opt for paper or mesh containers that allow airflow.
Pro tip: Keep potatoes away from onions and other produce. The gases released by some fruits and vegetables can speed up sprouting and spoilage.
The Bottom Line
Even if you plan to peel them, always wash your potatoes before cooking. It’s a simple step that prevents contamination, ensures cleaner flavors, and keeps your kitchen safe. Whether you’re making creamy mashed potatoes or a crispy potato salad, taking a few moments to rinse off the dirt is worth it—because no one wants to eat dirt, right?
