These crispy sweet potato and zucchini fritters are packed with spring onions, parsley, and garlic. A quick vegetable-packed snack or side dish ready in 20 minutes with simple pantry ingredients.
Sweet Potato and Zucchini Fritters
I started making these sweet potato and zucchini fritters on days when the fridge had those vegetables that needed using up, but nothing that added up to a proper meal on its own. A sweet potato, a zucchini, some spring onions — individually unremarkable, but grated and mixed into a spiced batter and fried until the edges go properly golden and crispy. Then they become something genuinely worth making on purpose.
Though I’m not suggesting making these fritters every so often due to the frying method, they’re nice to enjoy from time to time. They can be a snack, a side dish, or a light lunch with a dipping sauce alongside. I’ve also made them for people who claim not to like vegetables and watched them eat six in a row without noticing, like my two fussy boys.
So if you like these veggies and need some idea of what to turn them into, this recipe is for you.
Why You’ll Love This Recipe
- Sweet potato and zucchini are a better combination than they sound. The natural sweetness of the sweet potato balances the zucchini’s mild, slightly bland flavor. Together in a spiced batter, they create something more interesting than either vegetable does alone.
- Completely vegetarian with no substitutions needed. The recipe as written contains no meat, no fish sauce, and no hidden animal products beyond eggs. Straightforwardly vegetarian and genuinely satisfying as it is.
- Flexible with what you have. You can use the recipe as a template. Different vegetables, different herbs, different spices — the batter ratio stays the same, and the method doesn’t change. It’s a useful base recipe to know.
- Great for batch cooking. Make a double batch, cool completely, and refrigerate. Reheat in the oven, air fryer, or a dry pan, and they crisp back up well. Better than most fried foods for the next day.
- Works across multiple occasions. Serve as a snack with dipping sauce, as a side dish with grilled meat or fish, as a light lunch with a green salad, or as a starter at a casual dinner. They fit almost any context without modification.
Ingredients You Need
- 1 medium sweet potato, grated
- 1 medium zucchini, cut into matchsticks
- 2 scallions (spring onions), sliced
- A handful of flat parsley leaves, chopped
- 1½ teaspoons garlic powder
- 1 teaspoon white pepper powder
- 1 teaspoon salt, or to taste
- 1 teaspoon dried red chili pepper flakes (optional)
- 2 eggs, lightly beaten
- 1 cup / 120g all-purpose flour
- Frying oil
How to Make Sweet Potato and Zucchini Fritters
- Combine the vegetables by placing the grated sweet potato, zucchini matchsticks, sliced spring onions, and chopped parsley into a large mixing bowl.
- Make the batter by adding the garlic powder, white pepper, salt, chili flakes (if using), beaten eggs, and flour to the vegetables. Mix everything together until you have a thick, sticky batter. If the mixture feels too dry, add water gradually — up to a maximum of ⅓ cup. The batter should be sticky and hold its shape when spooned, not runny.
- Heat the oil in a wok or large frying pan over medium-high heat. The oil should be deep enough to come about halfway up the side of a fritter.
- Fry the fritters by spooning the batter carefully into the hot oil, flattening each one slightly. Don’t overcrowd the pan — leave space between each fritter so they fry rather than steam. Cook for 4–5 minutes until the edges are visibly golden brown and crispy.
- Flip and finish by carefully turning each fritter and cooking for a further 4–5 minutes, until golden brown and crispy on both sides.
- Drain and serve by removing from the oil and placing on a plate lined with kitchen paper to absorb excess oil. Serve immediately while the edges are still crispy.
Top Tips
- Grate the sweet potato coarsely, not finely. Fine gratings break down too much during frying, making the fritter dense. Coarse gratings keep some texture and cook more evenly.
- Cut the zucchini matchsticks consistently. Pieces that are roughly the same size cook at the same rate. Inconsistent cutting means some pieces are overdone while others are undercooked.
- The batter should be sticky, not pourable. If you can pour it from the bowl, it’s too wet. Add flour a tablespoon at a time until it holds its shape when spooned. A runny batter spreads too thin in the oil and won’t crisp properly.
- Medium-high heat, not high. Too high and the outside browns before the sweet potato inside has time to cook through. Medium-high gives you a properly cooked center and a crispy exterior within the same 4–5-minute window.
- Serve straight from the oil. Fritters are at their absolute best in the first five minutes after coming out of the pan. The edges soften as they cool — eat them hot.
Substitutes and Variations
- Vegetable swaps: Replace zucchini with grated carrot for a sweeter, firmer fritter. Corn kernels stirred into the batter add bursts of sweetness. Shredded cabbage or leek works well as a partial or full replacement for zucchini.
- Herb alternatives: Flat parsley can be swapped for fresh coriander if you prefer a more Southeast Asian flavor profile, or fresh chives for something milder and more onion-forward.
- Spice variations: Swap white pepper for smoked paprika for a warmer, earthier note. Ground cumin adds a Middle Eastern angle that works surprisingly well with sweet potato. Cajun spice mix replaces the individual seasonings for a bolder, spicier fritter.
- Add cheese: A handful of grated mature cheddar or crumbled feta stirred into the batter adds richness and a salty contrast to the sweet potato. Feta with the chili flakes is a particularly good combination.
- Make them smaller: Use a dessert spoon instead of a tablespoon to make bite-sized fritters — perfect for serving as canapés or party food with a dipping sauce.
Storage
Same day: Best eaten immediately while the edges are still crispy. They soften within 20–30 minutes at room temperature as moisture from the vegetables redistributes through the batter.
Refrigerator: Store cooled fritters in an airtight container lined with kitchen paper for up to 2 days. Reheat in a dry frying pan over medium heat for 2–3 minutes per side, or in the oven at 375°F / 190°C for 8–10 minutes, or in an air fryer at 375°F / 190°C for 3 minutes. Avoid the microwave — it makes them soft and limp.
Freezer: Freeze the cooled fritters in a single layer on a tray until solid, then transfer to a freezer bag, placing baking paper between each fritter. Keeps for up to 2 months. Reheat from frozen in the oven at 375°F / 190°C for 12–15 minutes until heated through and crispy on the outside.
Raw batter: The batter can be refrigerated for up to 24 hours before frying. Give it a stir before cooking — it may thicken slightly in the fridge, in which case add a small splash of water to loosen.
What to Serve With
- Sriracha mayo: the same sauce from the chicken katsu salad recipe works perfectly here. Creamy, spicy, and ready in four minutes.
- Tomato chili chutney: similar in taste to tomato salsa; the chutney will cut through the fried taste.
- Mint yogurt chutney: this spiced and herby yogurt pairs well with the fritters.
- Sour cream and chives — the cool creaminess against a hot, crispy fritter is the most straightforward and effective pairing. A squeeze of lemon over the top takes it further.
- Sweet chili sauce — a simple store-bought option that works especially well with the sweet potato’s natural flavor.
Common Questions Answered
Do I need to squeeze the moisture out of the zucchini first?
Not for this recipe. Cutting the zucchini into matchsticks rather than grating it means significantly less moisture is released. If your zucchini is very large and watery, pat the matchsticks dry with kitchen paper instead before adding them to the bowl.
Can I bake these sweet potato fritters instead of frying?
Yes. Place spoonfuls of batter on a lined baking tray, flatten slightly, and brush or spray generously with oil. Bake at 400°F / 200°C for 20–25 minutes, flipping halfway. The edges won’t be as deeply crispy as pan-fried, but they’re still very good and significantly lighter.
Can I make these fritters gluten-free?
Yes. Replace the all-purpose flour with a 1:1 gluten-free flour blend.
Can I use a different vegetable instead of zucchini?
Yes. Grated carrot, thinly sliced leek, corn kernels, or shredded cabbage all work in the same batter. Keep the total volume of vegetables roughly the same as in the recipe, and maintain the correct batter ratio.
Sweet Potato and Zucchini Fritters
Ingredients
- 1 medium-sized sweet potato grated
- 1 medium-sized zucchini cut into matchsticks
- 2 scallions spring onions, sliced
- A handful of flat parsley leaves chopped
- 1½ teaspoon garlic powder
- 1 teaspoon white pepper powder
- 1 teaspoon salt or according to taste
- 1 teaspoon dried red chili pepper flakes optional
- 2 eggs lightly beaten
- 1 cup all-purpose flour (plain flour)
- Frying oil
Instructions
- Place the grated sweet potato, zucchini matchsticks, sliced scallions (spring onions), and chopped parsley in a large mixing bowl.
- Add one and a half teaspoons of garlic powder, one teaspoon of white pepper powder, one teaspoon salt (or according to your taste), one teaspoon dried red chili pepper flakes (if using), two beaten eggs, and one cup of all-purpose flour into the vegetables.
- Mix everything well until you get a sticky batter. If it is too dry, you can add a little water. I usually put about ⅓ cup of water max. Take care not to put too much water, as we don’t want the batter to get too runny.
- Heat the oil in a wok or large frying pan. Then spoon the fritter batter into the hot oil and carefully slide it in. Do the same until the oil is filled with the batter, but make sure it is not too crowded. Fry at medium-high heat for about 4-5 minutes, until the edges turn golden brown.
- Turn the fritters one by one and continue cooking for another 4-5 minutes, until golden brown and crispy on the edges. Take them off the oil and place them on a plate lined with kitchen paper.
Notes
- Grate the sweet potato coarsely, not finely, to prevent the fritters from becoming dense.
- Cut the zucchini into similar, consistent sizes as best you can so they will cook evenly.
- Pat the zucchini sticks dry before adding them to the batter to reduce the water.
- Make sure the batter is thick and not in a pouring consistency.
