Buy by the cooking job, not by the color on the label. Beauregard is the sensible all-purpose orange-fleshed root. Garnet is sweeter and very moist, Jewel is milder, Japanese types are denser and starchier, and purple-fleshed roots are drier and take longer to cook. Whatever you choose, pick roots that are firm, dry and smooth, with no cuts, sprouts, soft spots or bruises, and store them out of the refrigerator.
Start with the texture you want
There is no single best sweet potato for every recipe. The differences are mostly in eating quality, and that is what should drive your choice. USDA Agricultural Research Service researcher Matthew Allan, in an ARS interview, put it this way: “The biggest difference between flesh colors is the eating experience since they have varying textures, aromas, and sweetness levels that make each flesh color unique.” He also said it is hard to name one type as the best. The interview is a researcher’s view, not a formal USDA recommendation. (USDA ARS)

Variety comparison
The table below uses the descriptions from two university extension sources and the U.S. Sweet Potato Council. Skin color is listed where the sources agree or where they differ. Treat each row as a tendency, since cultivar, growing conditions, storage and local naming all change what reaches the shelf.
| Type | What the sources describe | Best-fit uses named in the sources |
|---|---|---|
| Beauregard | UMass calls it the most common all-purpose type, with orange skin and flesh, and describes it as sweet and juicy. Rutgers describes purple-red skin with orange flesh, so the skin wording differs between sources. | All-purpose; mashing, baked goods and baking (Rutgers says especially good for baking). |
| Jewel | UMass describes light orange skin and orange flesh, and says it is less sweet than Beauregard. Rutgers describes copper-toned skin and a mildly sweet taste. | All-purpose; baking, boiling and casseroles. |
| Garnet | UMass describes dark reddish-purple skin, a sweet flavor and very moist flesh. Rutgers describes red-purple skin with bright orange flesh. | Pies, mashing and casseroles (UMass); baking (Rutgers). |
| Japanese (Satsuma) | UMass describes dark purple skin, pale yellow flesh, a slight nutty flavor, and a denser, starchier texture. Rutgers describes purple skin, white flesh, and a floral, sweet and nutty taste. | A denser, starchier root; Rutgers suggests braising, boiling or stir-frying. |
| Purple-fleshed | Rutgers describes purple skin and flesh, a slightly sweet, wine-like taste, and a drier, starchier texture. | Boiling, roasting or baking; Rutgers notes these take longer to cook. |
The U.S. Sweet Potato Council groups roots broadly into five appearance types: orange skin with orange flesh, red skin with orange flesh, yellow skin with white flesh, purple skin with white flesh, and purple skin with purple flesh. It says each has its own flavor and texture. These are broad groups, not a complete list of cultivars. (U.S. Sweet Potato Council)

- TRIPLE WASHED: Means that you do not need to spend time washing them, because we already have! Three times, in fact.
How to choose for your recipe
- Baking, pies and mashing where you want sweetness and moisture: Beauregard or Garnet. The sources name both for these uses.
- Casseroles or boiling where you want a milder flavor: Jewel.
- Stir-fries, braises or dishes where a firmer, drier bite is wanted: Japanese types or purple-fleshed roots, budgeting extra cooking time for the purple ones.
- Mixed cooking in one pan: buy roots of similar size so they cook at the same rate.
What to check at the store
- Firm, dry and smooth skin, without cuts, sprouts, soft spots, bruises or visible decay.
- Roots of similar size if you are cooking them together.
- Variety or color names that match the recipe, plus a check that the label matches the flesh you see when you cut into one. Skin and flesh color are separate traits, and labels are not applied consistently across sources.

Yams on the label
In U.S. grocery stores, an item sold as a “yam” is usually an orange-fleshed sweet potato. True yams belong to the Dioscorea genus, are unrelated to sweet potatoes, and are not common U.S. grocery products. If you are shopping for a true yam, check the origin and product name rather than assuming the label is accurate. (USDA ARS)
Storage after you bring them home
- Leave the roots unwashed. Washing adds moisture that can encourage rot.
- Keep them in a cool, dark, dry, ventilated place away from heat.
- Do not refrigerate whole roots.
- Use them within two weeks for best quality, according to UMass. Actual keeping time depends on the root and conditions.

What USDA grades do and do not tell you
USDA grade language is a commodity standard, not a taste ranking. The U.S. Extra No. 1 grade describes roots as firm, smooth, fairly clean and fairly well shaped, with listed defect exclusions. A higher grade may mean fewer defects, but it does not guarantee the sweetness or texture you prefer. Use the grade to judge condition, and use the variety description to judge flavor. (USDA AMS standards)
Rank #2
- Selected and stored fresh
- Sourced with high quality standards
- Recommended to wash before consuming
- Delicious on their own as a healthy snack or as part of a recipe
What the sources cannot settle
The sources reviewed in October 2026 do not provide a comparative nutrition figure that would justify choosing one variety over another, and nothing here supports calling purple-fleshed roots healthier than orange ones. UMass lists nutrition facts for a large sweet potato, but that is a single serving figure, not a variety comparison. Choose on flavor, texture and cooking method, which is where the sources give real guidance.
Labels and naming vary by market and region, so if a variety you want is not on the shelf, the texture descriptions above are the more reliable guide to a substitute than the name alone.
Rank #3
- Selected and stored fresh
- Sourced with high quality standards
- Recommended to wash before consuming
- Delicious on their own as a healthy snack or as part of a recipe
The rule is simple: match the root to the recipe, check its condition, and keep it cool and dry until you cook it.
