- Cut Sweet Potatoes: Peel (optional) and cut the sweet potatoes into evenly sized cubes or wedges to ensure even cooking.
Add Water to a Pot: Place the sweet potatoes in a large pot and add enough water to cover them completely. Add a pinch of salt if desired, which can enhance the flavor.
Bring to a Boil: Cover the pot and bring the water to a boil over medium-high heat.
Boil the Sweet Potatoes:

4. How to Tell When Sweet Potatoes Are Done Boiling

To check if your sweet potatoes are done boiling, look for these signs:

Fork or Knife Test: Insert a fork or knife into the thickest part of the sweet potato. If it slides in easily without resistance, the sweet potato is done.
Tenderness: Sweet potatoes should be tender but not falling apart. They should have a soft, creamy texture when cooked through.
No Firmness: If you feel any firmness or resistance when piercing the potato, it needs more time to cook.

5. Tips for Perfectly Boiled Sweet Potatoes

Use a Large Enough Pot: Ensure your pot is large enough to comfortably fit the sweet potatoes with room for water to cover them. This ensures even cooking.
Check for Even Cooking: If boiling whole sweet potatoes, try to select ones that are similar in size to ensure even cooking.
Don’t Overcrowd the Pot: If boiling cut pieces, don’t overcrowd the pot. Give the pieces room to cook evenly.
Avoid Overcooking: Keep an eye on the time. Overcooking sweet potatoes can result in them becoming too soft, losing flavor and texture.
Peel After Boiling: If you prefer peeled sweet potatoes, it’s easier to peel them after boiling. The skin will peel off easily once they’re soft.

6. Common Mistakes to Avoid

Overcooking the Sweet Potatoes: If sweet potatoes are boiled for too long, they can become waterlogged and lose their flavor. Be sure to check them periodically to avoid overcooking.
Not Cutting Evenly: When cutting sweet potatoes into pieces, try to make the pieces as uniform as possible. This ensures that they cook evenly and at the same rate.
Not Testing for Doneness: Always test for doneness by inserting a fork or knife. Don’t rely solely on the timer.
Boiling in Too Little Water: Make sure the sweet potatoes are fully submerged in water. If the water level is too low, the potatoes may cook unevenly.
