How to Make Vietnamese Sweet Potato Prawn Fritters
-
Prepare the Nuoc Cham:
Whisk together the fish sauce, white vinegar, sugar, lime juice, chopped red chilli, and minced garlic in a bowl. Set it aside so the flavors meld together beautifully while you work on the fritters. -
Make the Batter:
In a mixing bowl, combine the plain flour, cornflour, baking powder, turmeric, and salt. Create a well in the center, crack in the egg, and gradually whisk in iced water until you have a thick batter. Gently fold in the sweet potato and chopped prawns for added flavor. -
Heat the Oil:
Fill a wok or deep frying pan with oil to about one-third capacity and heat over high. Test if the oil is ready by dipping a wooden spoon into it; if bubbles form around the spoon, it’s ready for frying. -
Fry the Fritters:
Scoop spoonfuls of your fritter batter into the hot oil, shaping them into small rounds. Fry them for about 4 minutes, turning them halfway through, until they are crispy and golden brown. Transfer them to a plate lined with paper towels to drain excess oil and sprinkle with a little sea salt. Repeat this step with the remaining batter. -
Serve and Enjoy:
Arrange your crispy fritters on a platter and serve alongside the Vietnamese-style Tangy Dressing and the prepared nuoc cham for a delightful dipping experience.
Optional: Drizzle with lime juice for an extra zesty flavor.

How to Store and Freeze Vietnamese Sweet Potato Prawn Fritters
Room Temperature: Store leftover fritters at room temperature for up to 1 hour if you plan to eat them soon. Keep them on a wire rack to maintain their crispiness.
Fridge: Place cooled fritters in an airtight container and refrigerate them for up to 2 days. Reheat in a skillet or oven to regain some crispness before serving.
Freezer: For longer storage, freeze uncooked fritters on a baking sheet until firm, then transfer to a freezer bag. They can stay fresh for up to 1 month. Fry directly from frozen, adding a couple of extra minutes to the cooking time.
Reheating: To reheat, use an oven preheated to 375°F (190°C) for about 10-15 minutes until crispy, or fry in a bit of oil for 2-3 minutes for that fresh-out-of-the-oil taste!
Expert Tips for Vietnamese Sweet Potato Prawn Fritters
-
Batter Consistency: Make sure your batter is thick but pourable. Too runny, and the fritters will spread; too thick, and they won’t cook through properly.
-
Oil Temperature: Use a thermometer if possible. The oil should be around 350°F (175°C) for perfect frying. If it’s too hot, the fritters will burn on the outside before they’re cooked inside.
-
Small Batches: Fry in small batches to avoid overcrowding the pan, which can lower the oil temperature and lead to soggy fritters.
-
Season Generously: Don’t forget to sprinkle extra sea salt on your fritters just after draining them for a flavor boost.
-
Fresh Ingredients: Always use fresh prawns; they significantly enhance the overall flavor and texture of your Vietnamese Sweet Potato Prawn Fritters.
-
Experiment with Dips: While nuoc cham is traditional, don’t hesitate to try other dips like a spicy mayo or soy sauce for a personalized twist!

Vietnamese Sweet Potato Prawn Fritters Recipe FAQs
How do I select ripe sweet potatoes?
Choosing the right sweet potatoes is crucial! Look for firm ones without any dark spots or soft areas. A vibrant orange color usually indicates sweetness and proper ripeness. I always go for those that are smooth and free of blemishes.
How should I store leftover fritters?
If you have any fritters left, place them in an airtight container and refrigerate for up to 2 days. To reheat, simply pop them in a skillet over low heat, or for a crispier finish, use your oven at 375°F (190°C) for about 10-15 minutes. It’s a great way to enjoy them again!
Can I freeze Vietnamese Sweet Potato Prawn Fritters?
Absolutely! To freeze uncooked fritters, lay them out on a baking sheet and place them in the freezer until firm. Once frozen, transfer them into a freezer bag where they can stay fresh for up to 1 month. When you’re ready to cook, fry them directly from frozen, adding an extra 2-3 minutes to the cooking time.
What should I do if my fritters are too greasy?
If your fritters turn out too greasy, it might be due to the oil being too cool while frying. Ensure your oil temperature is around 350°F (175°C). If they absorb too much oil, frying smaller batches helps maintain the oil’s temperature, resulting in crispier, less greasy fritters.
Are there any dietary considerations when making these fritters?
Yes! Make sure to check for allergies, especially for the prawns and fish sauce used in the nuoc cham. If you’re making these for someone with seafood allergies, feel free to substitute the prawns with cooked chickpeas or diced vegetables for a delightful vegetarian alternative that still packs a punch.
How can I make the batter light and fluffy?
To ensure your batter is light and fluffy, whisk the eggs and add iced water gradually to create a thick mixture. You can even let it sit for about 10 minutes. This gives the flour time to hydrate, leading to a lighter texture when cooked. I recommend taking your time with this step for the best results!
