4 min read

Potato skins can increase the nutritional value of a dish by up to 35%, according to a study cited by Lamb Weston. Knowing which potatoes do you not need to peel can significantly boost the fiber, vitamins, and minerals in your meals while saving you preparation time.

Quick Summary

Discover which thin-skinned potato varieties like Yukon Golds and new potatoes are best to cook unpeeled, maximizing their nutritional content and adding rustic texture to your dishes. Also learn about safety, cleaning, and preparation tips for enjoying potatoes with their skins on.

Key Points

  • Embrace Thin-Skinned Potatoes: Waxy varieties like Yukon Golds, red potatoes, new potatoes, and fingerlings have thin, flavorful skins that are best left unpeeled for both taste and nutrition.

  • Boost Your Nutrition: Potato skins are a concentrated source of fiber, vitamins, and antioxidants, so keeping them on can significantly increase the nutritional value of your meal.

  • Avoid Green Spots and Sprouts: Always scrub potatoes and remove any green patches or sprouts, as these indicate the presence of solanine, a natural toxin.

  • Match the Potato to the Dish: While unpeeled potatoes are great for roasting and salads, thick-skinned varieties like russets are typically peeled for creamy dishes such as smooth mashed potatoes.

  • Prioritize Proper Storage: Store potatoes in a cool, dark, and dry place to prevent them from turning green and developing high levels of solanine.

  • Consider Cooking Method: For a crispy finish, roast thin-skinned potatoes with the skin on. For a rustic mash, a food mill or ricer can help break down the skins after boiling.

The Nutritional Advantage of Keeping the Skin On

For a nutritional diet, leaving the skin on your potatoes is a simple and effective strategy. The skins are packed with beneficial nutrients that are often discarded during the peeling process. Key nutrients found in potato skins include fiber, potassium, Vitamin C, B vitamins, and various antioxidants. Fiber is essential for digestive health and can promote a feeling of fullness. Potassium plays a crucial role in regulating blood pressure, while antioxidants combat inflammation and protect cells from damage. By cooking potatoes with the skin intact, you are ensuring that these valuable compounds make it to your plate. To gain the most benefit, especially in terms of antioxidants, consider using colorful varieties like red and purple potatoes.

Understanding Potato Types and Their Skins

Not all potatoes are created equal, and their skin is a major differentiating factor. Potatoes are typically categorized as starchy, waxy, or all-purpose. This classification is a key indicator of whether the skin is suitable for eating.

  • Waxy potatoes have low starch and high moisture content, and their thin skins remain intact and edible after cooking. This makes them ideal for dishes like potato salads or roasting.
  • Starchy potatoes, like Russets, have thick, rough skins and a fluffy, dry flesh. While the skin is edible when baked to a crisp, it's often peeled for a smooth texture, such as for mashed potatoes.
  • All-purpose potatoes fall in between, with medium starch and thinner skins, and can be used for most dishes, often with the skin left on.

The Best Potatoes to Cook Unpeeled

To answer the question of which potatoes do you not need to peel, you should prioritize thin-skinned and waxy varieties. These potatoes are known for their flavor and texture when left unpeeled.

  • Yukon Golds: This popular all-purpose potato has a thin, buttery-flavored golden skin that is delicious when left on. It's a great choice for roasting, mashing, and making potato salads.
  • Red Potatoes (Red Bliss): Known for their thin, vibrant red skin and waxy texture, red potatoes hold their shape beautifully after cooking. They add a visually appealing element and robust flavor to roasted dishes and salads.
  • New Potatoes: These small, young potatoes of various varieties have very thin, delicate skins that don't require peeling. They are perfect for boiling, steaming, or roasting whole.
  • Fingerling Potatoes: With their elongated shape and thin, buttery skin, fingerlings are an excellent waxy variety for cooking unpeeled. They are commonly roasted or boiled for a unique presentation and flavor.
  • Purple/Blue Potatoes: These all-purpose spuds have a vibrant, colorful skin rich in antioxidants and are typically thin enough to leave unpeeled. Their unique color adds excitement to meals.

Safe Preparation and Storage

Regardless of the potato type, proper cleaning and storage are essential. Always scrub potatoes thoroughly under running water with a vegetable brush to remove dirt, bacteria, and pesticide residue. Cut away any sprouts or green spots, as these areas contain high concentrations of the natural toxin solanine, which can cause digestive issues. To prevent greening, store potatoes in a cool, dark, and dry place. If a potato is excessively green or tastes bitter after cooking, discard it entirely.

Tips for Cooking Potatoes with Skin On

  • Wash thoroughly: Scrub vigorously with a vegetable brush under running water to remove all dirt.
  • Use the right type: Select thin-skinned varieties like Yukon Golds, new potatoes, or reds for best results.
  • Roast for crispiness: For roasted potatoes, the skin adds a delicious, crispy texture.
