Culinary Notes

Chef's Note

Boniato Beauregard leans creamy and gentle rather than candy-sweet, so it holds up beautifully to high-heat browning and still mashes into silk. Use it with fats (brown butter or coconut milk) and a bright acid (lime) to keep the sweetness clean and the finish nutty.

Best Uses

roasted wedges or halves until you get caramelized edges and a spoonable center
whipped mash for a silky, slice-stacks breakfast or holiday side
simmered into creamy soups and puree-based sauces
pan-seared coins or batons to build a browned crust before finishing tender

Flavor Profile

velvety, creamy flesh gentle sweetness with a clean nutty finish firm-yet-tender bite that turns silky when cooked light, smooth skin that caramelizes around the edges

Frequently Asked Questions

How do I manage sweet potato (Boniato ‘Beauregard’) leaf spot or bacterial blight in my home garden?

Watch for dark, water-soaked spots that enlarge into lesions on leaves and stems, often worsening in humid weather. Remove and discard badly infected vines, then improve airflow by spacing slips so plants don’t crowd; avoid wetting foliage when watering. If the problem keeps spreading, use a copper-based fungicide labeled for sweet potatoes early in the outbreak and repeat according to the label until lesions stop expanding.

How often should I water Boniato ‘Beauregard’ during the main growing phase to get good tuber size?

After slips take hold, water deeply about 1–2 times per week, aiming for evenly moist soil during active vine growth rather than soggy beds. Check with your finger: the top 1–2 inches should be dry before you water again, and the soil should be moist 6–8 inches down where roots are forming. Stop regular watering about 10–14 days before harvest so the tubers cure better and skin doesn’t stay overly wet.

When are Boniato ‘Beauregard’ sweet potatoes ready to harvest, and what signs should I look for?

Harvest at about 110 days from planting slips, typically once vines start to yellow and die back. Dig one test tuber: mature ‘Beauregard’ should have well-formed, firm skin that doesn’t rub off easily. If nights are frost-free, you can wait for fuller sizing, but lift before the first hard frost and avoid leaving tubers in cold, wet soil.
