Understanding the Weight of a Fingerling Potato
Determining the exact weight of a single fingerling potato is not an exact science, as size and variety play a significant role. However, most culinary sources and grocery retailers agree on a general range. On average, a single fingerling potato typically weighs between 50 and 85 grams (approximately 2 to 3 ounces). This differs significantly from larger, more common potato varieties like Russets or Yukon Golds, which can weigh much more per individual tuber. The weight difference is a key factor when adjusting recipes or calculating nutritional content.
Factors that influence the weight of a fingerling potato include:
- Variety: Different fingerling varieties, such as Russian Banana, French Fingerling, or Purple Peruvian, have distinct sizes and shapes, which affects their individual weight.
- Maturity at Harvest: Though fingerlings are fully mature when picked, there can still be slight size variations within a single harvest, as noted by America's Test Kitchen.
- Growing Conditions: Environmental factors during cultivation, such as soil quality and spacing, can lead to different-sized potatoes, with growers sometimes crowding plants to produce smaller tubers.
Common Fingerling Potato Varieties and Their Size
The fingerling category includes several unique varieties, each with its own characteristics:
- Russian Banana: A common yellow-skinned, waxy fingerling known for its buttery flavor.
- French Fingerling: A larger varietal compared to others, averaging 7 to 10 centimeters in length and featuring pink-red skin.
- Purple Peruvian: Known for its deep purple skin and flesh, this variety offers an attractive color and distinct flavor.
- Snow Finger: An early harvest variety that produces medium to large tubers and works well for various cooking methods.
- Mix Peewee Fingerling: These are tiny, round or oval potatoes less than 2 centimeters in diameter, and are often a mix of colors.
Fingerling vs. Other Potatoes: A Weight and Culinary Comparison
When choosing potatoes for a recipe, understanding the differences in weight, size, and texture is crucial. This table highlights how fingerlings compare to other popular potato types.
| Feature | Fingerling Potatoes | Russet Potatoes | Yukon Gold Potatoes |
|---|---|---|---|
| Average Weight (Single) | 50-85 grams (2-3 oz) | ~450 grams (1 lb) | ~225 grams (8 oz) |
| Shape and Size | Small, slender, and finger-like | Large, oblong | Medium, round, slightly waxy |
| Texture | Firm and waxy | Fluffy and starchy | Creamy, all-purpose |
| Best For | Roasting, potato salads, boiling | Frying, mashing, baking | Mashing, roasting, soups, stews |
| Skin | Thin, edible, does not need peeling | Thick, needs peeling for some uses | Thin, edible |
Calculating Serving Size with Fingerling Potatoes
A typical serving of potatoes is often measured around 150 grams (approximately 5 ounces). Based on the average weight of 50 to 85 grams per fingerling potato, a standard serving would consist of approximately two to three individual potatoes. For recipes calling for a specific weight, such as a pound of potatoes (approximately 454 grams), you would need to use six to nine fingerlings. This makes portioning easy for roasted dishes, salads, and side dishes. For precise measurements, especially in baking, it is always best to weigh your potatoes. However, for a simple roasted side dish, counting out a few fingerlings per person is a quick and effective method.
Nutritional Profile: The Benefits of Fingerlings
Beyond their convenient size and delightful flavor, fingerling potatoes offer several nutritional benefits, especially when consumed with their thin, edible skin left on. They are a good source of vitamins, particularly vitamin C and B6, and minerals like potassium. The skin is also a significant source of dietary fiber and antioxidants. Colorful varieties, like the purple fingerling, contain anthocyanin, an antioxidant that fights free radicals. Given their lower glycemic index compared to larger, starchier potatoes, they are also recognized as a healthy carbohydrate choice.
Expert Cooking Tips for Fingerling Potatoes
- Wash Carefully: Due to their thin and delicate skin, fingerlings should be washed gently. Soaking them first can help loosen any dirt. Avoid using stiff brushes that might tear the skin.
- Proper Boiling: When boiling fingerlings for a salad or prior to roasting, start them in cold, heavily salted water. This ensures even cooking from the inside out and helps prevent them from crumbling, which is a common issue with starchy potatoes.
- Perfect Roasting: For a crispy exterior, parboil the fingerlings first and then allow them to dry completely before roasting. Roasting on a high heat with some baking soda in the boiling water can create a fluffy, extra-crispy surface.

- Flavorful Braising: Braising fingerlings in a rich chicken or vegetable stock results in incredibly tender and flavorful potatoes. Searing them first can add a desirable caramelized exterior.
- Keep the Skin On: The thin skin not only adds texture and color to your dish but is also full of nutrients. Don't waste it; enjoy the full flavor and health benefits of the whole potato.
Conclusion
To answer the question, a single fingerling potato typically weighs between 50 and 85 grams, though the exact weight depends on the specific variety and size. Their small, waxy nature makes them a versatile culinary ingredient, perfect for dishes like roasted potatoes and potato salads where they hold their shape beautifully. Nutritionally, fingerlings are an excellent choice, providing a healthy dose of vitamins, minerals, and fiber, especially when eaten with the skin on. By understanding the average weight and characteristics of these small tubers, you can easily incorporate them into your cooking for a gourmet touch and perfectly portioned meals.
