Sweet potatoes are a nutritional powerhouse, packed with vitamins, minerals, and fiber. They’re incredibly versatile in the kitchen, lending themselves to both sweet and savory dishes. But choosing the right sweet potato at the grocery store can be the difference between a delightful meal and a disappointing one. This guide will walk you through everything you need to know to select the best sweet potatoes every time.
Understanding Sweet Potato Varieties
Not all sweet potatoes are created equal. Different varieties offer distinct textures and flavors. Knowing the common types will help you pick the right potato for your cooking needs.
Identifying Popular Varieties
The most common varieties you’ll find include:
- Beauregard: These have reddish-purple skin and orange flesh. They are one of the most readily available types and are known for their sweetness and moistness.
- Garnet: Similar in appearance to Beauregard, Garnet sweet potatoes also boast reddish skin and vibrant orange flesh. They are equally sweet and moist, perfect for baking and roasting.
- Jewel: These typically have a copper-colored skin and a deep orange flesh. They are slightly drier than Beauregards and Garnets, but still very sweet and delicious.
- Japanese (Muraski): With their striking purple skin and pale yellow flesh, Japanese sweet potatoes offer a unique flavor profile. They are less sweet and have a drier, starchier texture than orange-fleshed varieties.
- Hannah: Hannah sweet potatoes are distinguished by their tan skin and creamy white flesh. They are the least sweet of the common varieties and have a drier, almost potato-like texture.
Matching Varieties to Recipes
Consider the intended use of the sweet potato when choosing a variety. For example, if you want a sweet and moist potato for baking or mashing, Beauregard or Garnet varieties are excellent choices. If you prefer a less sweet and drier potato for fries or roasting, consider Hannah or Japanese varieties. Understanding the characteristics of each variety helps ensure the best outcome for your recipe.
Visual Inspection: Key Things to Look For
The first step in selecting sweet potatoes is a thorough visual inspection. Pay close attention to the skin and overall appearance.
Examining the Skin
The skin of a sweet potato should be smooth and relatively free of blemishes. Look for:
- Uniform Color: The color should be consistent across the entire potato. Discoloration can indicate bruising or damage.
- Smooth Texture: Avoid sweet potatoes with wrinkled or shriveled skin, as this suggests they are old and may be dry inside.
- Absence of Cuts or Bruises: Even small cuts or bruises can lead to spoilage. Carefully examine the entire surface for any imperfections.
- No Soft Spots: Press gently on the sweet potato. Any soft spots indicate decay.
Checking for Sprouts or Eyes
Sprouts, sometimes called “eyes,” are small growths that emerge from the sweet potato. While a few tiny sprouts are not necessarily a deal-breaker, avoid sweet potatoes with extensive sprouting, as this indicates the potato is past its prime and its flavor and texture may have deteriorated.
Considering Size and Shape
Choose sweet potatoes that are relatively uniform in size and shape. This ensures even cooking. Avoid overly large potatoes, as they can sometimes be woody or fibrous. Medium-sized potatoes are generally the best choice. Look for potatoes that are elongated and tapered, rather than squat or round.
The Touch Test: Assessing Firmness
After the visual inspection, use your sense of touch to assess the firmness of the sweet potato.
Feeling for Firmness
A good sweet potato should feel firm to the touch. Avoid any that feel soft, mushy, or hollow. A firm texture indicates that the potato is fresh and has a good moisture content.
Avoiding Soft Spots
As mentioned earlier, pay particular attention to soft spots. Gently press along the entire surface of the sweet potato to check for any areas that give way easily. Soft spots are a sign of decay and should be avoided.
Smelling for Freshness
While not always practical in a grocery store setting, a quick sniff can sometimes reveal valuable information.
Detecting Off-Odors
A fresh sweet potato should have a mild, earthy smell. If you detect any musty, moldy, or otherwise unpleasant odors, the sweet potato is likely spoiled and should be avoided.
Storage and Handling Considerations
Once you’ve selected your sweet potatoes, proper storage is essential to maintain their quality and extend their shelf life.
Proper Storage Techniques
- Cool, Dark, and Dry: Store sweet potatoes in a cool, dark, and dry place, such as a pantry or cellar. Avoid storing them in the refrigerator, as this can cause them to develop a hard core and affect their flavor.
- Good Ventilation: Ensure good ventilation to prevent moisture buildup, which can lead to spoilage. Store them in a basket or open container, rather than a plastic bag.
- Avoid Ethylene-Producing Fruits: Keep sweet potatoes away from ethylene-producing fruits like apples and bananas, as ethylene gas can cause them to ripen and spoil more quickly.
Shelf Life
When stored properly, sweet potatoes can last for several weeks, or even months. Check them regularly for any signs of spoilage and use them while they are still firm and unblemished.
Organic vs. Conventional Sweet Potatoes
Choosing between organic and conventionally grown sweet potatoes is a matter of personal preference and budget.
Understanding the Differences
- Organic: Organic sweet potatoes are grown without synthetic pesticides, herbicides, or fertilizers. They are often perceived as being healthier and more environmentally friendly.
- Conventional: Conventionally grown sweet potatoes may be treated with synthetic chemicals to control pests and diseases. However, they are generally safe to eat after washing and cooking.
Making the Right Choice
If you are concerned about pesticide residues or want to support organic farming practices, choose organic sweet potatoes. However, if budget is a concern, conventionally grown sweet potatoes are a perfectly acceptable option. Regardless of your choice, be sure to wash the sweet potatoes thoroughly before cooking.
Tips for Ensuring Quality
Beyond the basic visual and tactile checks, consider these additional tips to ensure you’re getting the best sweet potatoes:
Buy in Season
Sweet potatoes are typically harvested in the fall and winter months. Buying them during this peak season ensures that you are getting the freshest and most flavorful potatoes.
Check the Origin
If possible, look for sweet potatoes that are locally grown. Locally sourced produce is often fresher and has a smaller environmental footprint.
Avoid Pre-Washed Potatoes
While pre-washed potatoes may seem convenient, the washing process can sometimes damage the skin and shorten their shelf life. It’s better to wash them yourself just before cooking.
Recognizing Common Issues
Even with careful selection, sweet potatoes can sometimes have hidden issues. Here’s how to recognize and deal with some common problems:
Internal Discoloration
Sometimes, a sweet potato may appear perfect on the outside but have internal discoloration when cut open. This can be caused by chilling injury or disease. If the discoloration is minor, you can usually cut it away and use the rest of the potato. However, if the discoloration is extensive, it’s best to discard the potato.
Stringy Texture
Some sweet potatoes can have a stringy or fibrous texture, especially if they are old or overripe. While this doesn’t necessarily mean they are unsafe to eat, the texture can be unpleasant. To minimize stringiness, choose sweet potatoes that are firm and have a smooth skin.
Lack of Sweetness
If your sweet potato tastes bland or lacks sweetness, it may be due to the variety, growing conditions, or storage methods. To enhance the sweetness, try roasting the sweet potato with a little bit of maple syrup or brown sugar.
Creative Ways to Use Sweet Potatoes
Once you’ve selected the perfect sweet potatoes, the possibilities are endless. Here are just a few ideas to get you started:
- Roasted Sweet Potatoes: Toss cubed sweet potatoes with olive oil, herbs, and spices, and roast until tender and caramelized.
- Mashed Sweet Potatoes: Boil or bake sweet potatoes until soft, then mash with butter, milk, and seasonings.
- Sweet Potato Fries: Cut sweet potatoes into fries, toss with oil and spices, and bake or fry until crispy.
- Sweet Potato Casserole: A classic holiday dish made with mashed sweet potatoes, marshmallows, and a pecan topping.
- Sweet Potato Soup: Blend cooked sweet potatoes with broth, spices, and cream for a comforting and flavorful soup.

What are the best qualities to look for when selecting a sweet potato?
The best sweet potatoes are firm to the touch and have smooth, unblemished skin. Avoid any sweet potatoes with soft spots, bruises, cuts, or signs of sprouting, as these indicate that the potato is past its prime or may be damaged internally. A uniform shape is also preferable, as oddly shaped potatoes can be more difficult to peel and cook evenly.
Look for sweet potatoes that are vibrant in color, depending on the variety. Deep orange hues usually indicate a higher beta-carotene content, which is beneficial for your health. The overall appearance should be clean and appealing, suggesting that the potato has been handled carefully and stored properly.
What does the color of a sweet potato tell you about its flavor and texture?
While color isn’t the only indicator, it does provide some clues about the expected flavor and texture. Sweet potatoes with deep orange flesh tend to be sweeter and moister when cooked, often described as having a syrupy or caramelized flavor. These are often the most popular varieties.
Lighter-colored sweet potatoes, such as those with pale yellow or even white flesh, generally have a drier and starchier texture. They may not be as intensely sweet as their darker counterparts, but they still offer a pleasant, slightly nutty flavor. Consider your desired end result when choosing a color.
Should I worry about small imperfections on the skin of a sweet potato?
Minor imperfections, such as small blemishes or slight discoloration on the skin, are usually not a cause for concern, as long as the sweet potato is firm and free from soft spots. These superficial flaws often result from normal handling and storage and do not necessarily affect the quality or taste of the potato.
However, it’s important to distinguish between minor blemishes and deeper cuts, bruises, or signs of mold. Any signs of significant damage or decay suggest that the potato may be compromised and should be avoided. Opt for sweet potatoes with generally smooth, intact skin for the best quality.
How does size factor into choosing a sweet potato?
The ideal size of a sweet potato depends on your intended use and the number of servings you need. Smaller sweet potatoes are generally a good choice for single servings or when you want to roast them whole. Medium-sized sweet potatoes are versatile and suitable for most recipes.
Larger sweet potatoes can be more economical if you’re feeding a crowd or planning to use them in multiple dishes. However, be mindful that very large sweet potatoes may have a slightly coarser texture. Choose a size that aligns with your cooking plans to minimize waste and ensure optimal results.
Is there a difference between sweet potatoes and yams?
Sweet potatoes and yams are often confused, but they are actually distinct vegetables. In most US grocery stores, what’s labeled as “yam” is typically a variety of sweet potato with a darker, reddish skin and orange flesh. True yams are less common and have a rough, brown, bark-like skin and white or off-white flesh.
Yams tend to be starchier and less sweet than sweet potatoes. When selecting “yams” at the grocery store, remember that you’re likely buying a specific type of sweet potato. If you’re looking for a true yam, you may need to visit a specialty market that caters to Caribbean or African cuisine.
How should sweet potatoes be stored after purchase?
Once you bring your sweet potatoes home, store them in a cool, dark, and well-ventilated place, such as a pantry or root cellar. Avoid storing them in the refrigerator, as the cold temperatures can alter their flavor and texture. Ideal temperatures are between 55°F and 60°F (13°C and 16°C).
Proper storage is crucial to extend the shelf life of your sweet potatoes. With proper conditions, they can last for several weeks or even months. Avoid placing them near other produce that emits ethylene gas, such as apples or bananas, as this can cause them to ripen and spoil more quickly.
Can I freeze sweet potatoes to use later?
Yes, sweet potatoes can be frozen for later use, but they require some preparation first. It’s best to cook them before freezing, as raw sweet potatoes can become mushy and discolored when thawed. You can boil, bake, steam, or roast them until tender.
Once cooked, let the sweet potatoes cool completely and then mash or cube them, depending on your preference. Package them in airtight containers or freezer bags, removing as much air as possible to prevent freezer burn. Frozen sweet potatoes can last for several months.
