Ruby potatoes, with their striking red skin and creamy flesh, have been gaining popularity in kitchens and markets alike. But what exactly are they? This article explores everything you need to know about Ruby potatoes, from their origins and characteristics to their nutritional benefits and culinary uses.
Understanding the Basics of Ruby Potatoes
Ruby potatoes are a variety of potato known for their vibrant red skin and white or yellow flesh. They fall into the “new potato” category, which means they are harvested early in their growth cycle. This early harvesting contributes to their tender texture and delicate flavor. Unlike some potatoes bred for specific purposes, Ruby potatoes are considered an all-purpose variety.
Origins and Development
While the exact origins of the Ruby potato are not meticulously documented like some heirloom varieties, they are believed to be a relatively modern cultivar. Plant breeders likely developed them by cross-breeding different potato strains to achieve their distinctive red skin and desirable culinary characteristics. Modern breeding techniques focus on traits like disease resistance, yield, and flavor profile, all of which are important considerations in creating new potato varieties.
Key Characteristics
The most notable characteristic of Ruby potatoes is their smooth, bright red skin. This vibrant color makes them visually appealing on the plate. The flesh inside is typically white or a pale yellow. Ruby potatoes are usually small to medium in size and have a round or slightly oval shape. They possess a thin skin, which often doesn’t require peeling, adding to their convenience in the kitchen. Their texture is creamy and waxy, and their flavor is mild and slightly sweet, making them versatile for various cooking methods.
Nutritional Profile of Ruby Potatoes
Beyond their appealing appearance and taste, Ruby potatoes offer a range of nutritional benefits. They are a good source of essential vitamins, minerals, and dietary fiber.
Vitamins and Minerals
Ruby potatoes, like other potatoes, are a good source of vitamin C, an antioxidant that supports immune function and helps protect against cell damage. They also contain vitamin B6, which is essential for brain development and function. In terms of minerals, Ruby potatoes provide potassium, which is important for maintaining healthy blood pressure, and manganese, which plays a role in bone health and metabolism. The red skin also contains anthocyanins, antioxidant compounds also found in berries.
Fiber Content
Dietary fiber is an important component of a healthy diet, and Ruby potatoes contribute to your daily fiber intake. Fiber promotes digestive health, helps regulate blood sugar levels, and can contribute to feelings of fullness, which can aid in weight management.
Carbohydrates and Calories
Ruby potatoes are primarily composed of carbohydrates, which provide the body with energy. They also contain a moderate amount of calories. The exact calorie count varies depending on the size and preparation method, but a medium-sized Ruby potato typically contains around 150 calories.
Comparison with Other Potato Varieties
When compared to other potato varieties, Ruby potatoes hold their own nutritionally. They are similar to other red-skinned potatoes in terms of vitamin and mineral content. While sweet potatoes are known for their high vitamin A content, Ruby potatoes offer a good balance of nutrients and a lower glycemic index than some other potato types.

They also work well with garlic, onions, and other vegetables. In terms of protein, they complement fish, chicken, and beef. Their creamy texture also pairs well with dairy products like butter, cream, and cheese.
Growing and Harvesting Ruby Potatoes
For those with a green thumb, growing your own Ruby potatoes can be a rewarding experience. Here’s a brief overview of the process:
Planting and Care
Ruby potatoes are typically grown from seed potatoes, which are small potatoes that have sprouts or “eyes.” Plant seed potatoes in well-drained soil in a sunny location. Potatoes prefer slightly acidic soil. Regularly water the plants, especially during dry periods. Hilling, or mounding soil around the base of the plants, helps to protect the developing potatoes from sunlight and encourages further growth.
Harvesting Tips
Ruby potatoes are usually ready for harvest when the plants begin to flower. You can harvest them as “new potatoes” when they are small and tender, or you can wait until the plants die back for larger, more mature potatoes. Gently dig around the plants to harvest the potatoes, being careful not to damage them.
Storage Recommendations
Store harvested Ruby potatoes in a cool, dark, and dry place. A root cellar or a cool basement is ideal. Avoid storing them in direct sunlight, as this can cause them to turn green and develop a bitter taste. Properly stored Ruby potatoes can last for several months.
Where to Buy Ruby Potatoes
Ruby potatoes are becoming increasingly available in supermarkets and farmers’ markets.
Availability in Supermarkets
Many major supermarket chains carry Ruby potatoes, especially during peak season. Look for them in the produce section, typically near other potato varieties. Their bright red skin makes them easy to identify.
Local Farmers Markets
Farmers’ markets are a great place to find fresh, locally grown Ruby potatoes. Buying from local farmers supports sustainable agriculture and provides access to the freshest produce.
Online Retailers
Several online retailers also offer Ruby potatoes. This can be a convenient option if you are unable to find them locally or prefer to shop from home. However, be sure to check the retailer’s shipping policies and ensure that the potatoes are properly packaged to prevent damage during transit.
Distinguishing Ruby Potatoes from Similar Varieties
While their vibrant red skin makes them fairly easy to identify, it’s useful to understand how Ruby potatoes differ from other red-skinned potato varieties.
Comparing with Red Bliss Potatoes
Red Bliss potatoes are one of the most common red-skinned varieties. Like Ruby potatoes, they have a smooth, red skin and white flesh. However, Red Bliss potatoes tend to be slightly larger and more elongated in shape than Ruby potatoes. Their flavor is also slightly different; Red Bliss potatoes often have a more earthy taste, while Ruby potatoes are known for their mild sweetness. Texture-wise, both are considered waxy potatoes good for boiling, but some find Ruby potatoes slightly creamier.
Differences from Other Red-Skinned Potatoes
Several other red-skinned potato varieties exist, each with subtle differences. Some may have a deeper red skin color, while others may have a more russeted or textured skin. The flesh color can also vary, ranging from white to yellow to even slightly pinkish. The best way to distinguish Ruby potatoes is by their consistent bright red color, small to medium size, and creamy texture. The flavor profile also offers a good indicator; their mild, slightly sweet taste sets them apart from some of the earthier red-skinned varieties.
Potential Benefits of Consuming Ruby Potatoes
Beyond the general nutritional advantages, Ruby potatoes may offer some distinct benefits due to their specific composition.
Antioxidant Properties
The red skin of Ruby potatoes contains anthocyanins, which are powerful antioxidants. Antioxidants help protect the body against damage from free radicals, unstable molecules that can contribute to aging and chronic diseases. Consuming Ruby potatoes can contribute to your overall antioxidant intake and potentially support your health.
Glycemic Index Considerations
While all potatoes contain carbohydrates and will impact blood sugar levels, the glycemic index (GI) of different potato varieties can vary. Some studies suggest that red-skinned potatoes like Ruby potatoes may have a slightly lower GI than some other potato types, especially russet potatoes. A lower GI means that the carbohydrates are digested and absorbed more slowly, leading to a more gradual rise in blood sugar levels. This could be beneficial for people with diabetes or those looking to manage their blood sugar levels. It’s important to note that the GI of potatoes can also be affected by the cooking method and the other foods consumed with them.
Digestive Health Support
Ruby potatoes contain dietary fiber, which is essential for digestive health. Fiber adds bulk to the stool, promoting regular bowel movements and preventing constipation. Fiber can also help to nourish beneficial gut bacteria, contributing to a healthy gut microbiome.
In conclusion, Ruby potatoes are a vibrant and versatile potato variety that offers a range of nutritional benefits and culinary possibilities. From their striking red skin and creamy texture to their mild, slightly sweet flavor, they are a welcome addition to any kitchen. Whether you boil, roast, grill, or sauté them, Ruby potatoes are sure to delight your taste buds and provide you with essential vitamins, minerals, and fiber.
What makes Ruby potatoes distinct from other potato varieties?
Ruby potatoes are easily identified by their vibrant red skin and creamy white flesh. This striking color difference is a key distinguishing factor. Other potatoes might have brown, yellow, or even purple skin, but the bright red hue of the Ruby is unique.
Beyond color, Ruby potatoes are known for their smooth texture and slightly waxy consistency. This is due to their lower starch content compared to Russet potatoes, for example, resulting in a less floury potato when cooked. This characteristic makes them excellent for boiling, steaming, and salads, where maintaining their shape is desirable.
How should I store Ruby potatoes to maximize their shelf life?
To keep your Ruby potatoes fresh for as long as possible, store them in a cool, dark, and well-ventilated place. A pantry, cellar, or even a paper bag in a cool cupboard are suitable options. Avoid storing them near onions or apples, as these fruits release ethylene gas, which can cause potatoes to sprout prematurely.
Avoid washing Ruby potatoes before storing them. Moisture promotes mold growth and spoilage. Instead, brush off any excess dirt and store them dry. Properly stored, Ruby potatoes can last for several weeks to a couple of months.
What are the best cooking methods for Ruby potatoes?
Ruby potatoes are incredibly versatile, but their low starch content makes them particularly well-suited for certain cooking methods. Boiling and steaming are excellent choices because they help the potatoes retain their shape and texture without becoming mushy. They’re also fantastic roasted, as their skins crisp up nicely while the flesh remains tender.
Avoid using Ruby potatoes for mashed potatoes if you prefer a very fluffy, light texture. Their waxy consistency will result in a denser, creamier mash. Instead, consider them for potato salads, gratins, or simply boiled and tossed with butter and herbs.
Are Ruby potatoes nutritious? What are their key health benefits?
Like all potatoes, Ruby potatoes are a good source of several important nutrients. They contain Vitamin C, potassium, and fiber, all of which contribute to overall health. The red skin also contains antioxidants, offering additional health benefits.
Potassium is important for maintaining healthy blood pressure, while fiber aids digestion and promotes feelings of fullness. Vitamin C supports the immune system. While nutritious, remember that moderation is key, and balance Ruby potatoes within a healthy diet.
Where can I typically find Ruby potatoes for purchase?
Ruby potatoes are often available in supermarkets, especially during the late summer and fall harvest season. Look for them in the produce section alongside other potato varieties. Many farmers’ markets also carry Ruby potatoes when they are in season, offering a chance to support local growers.
Specialty food stores and some grocery chains with a wide selection of produce are also likely to stock Ruby potatoes. If you’re having trouble finding them, you can try searching online for local farms that sell directly to consumers.
Can I grow Ruby potatoes in my own garden?
Yes, you can absolutely grow Ruby potatoes in your own garden! They require similar conditions to other potato varieties. Start with seed potatoes (small, certified disease-free potatoes specifically for planting) and plant them in well-drained soil with plenty of sunlight.
Hilling, or mounding soil around the potato plants as they grow, is important to encourage more potato formation. With proper care, including watering and pest control, you can enjoy a bountiful harvest of Ruby potatoes from your garden.
What dishes pair well with Ruby potatoes?
Ruby potatoes work beautifully in a wide variety of dishes. Their slightly sweet and earthy flavor pairs well with herbs like rosemary, thyme, and parsley. They are also delicious with garlic, butter, and olive oil.
Consider using them in potato salads with vinaigrette dressings, as a side dish roasted alongside chicken or fish, or as a base for creamy gratins. Their versatility allows them to complement both simple and more complex flavors.
