Ingredients

For the Garlic Herb Yogurt Sauce

1/2 cup (120g) plain Greek or regular yogurt (or sour cream)
1 tablespoon chopped fresh parsley
1 tablespoon chopped fresh mint
1 tablespoon fresh lemon juice
1 tablespoon (15ml) olive oil
1 teaspoon honey
1/4 teaspoon garlic powder
Salt and freshly ground black pepper, to taste

For the Fritters

2 cups (about 240g) shredded zucchini (1–2 medium zucchini, about 1/2 lb.)
1 cup (100g) shredded sweet potato (1 small, peeled or unpeeled)
1/3 cup (45g) finely chopped yellow onion
1 and 1/2 teaspoons salt, divided
2 large eggs
2 garlic cloves, minced
2 tablespoons chopped fresh parsley
2 tablespoons chopped fresh mint
1/2 teaspoon freshly ground black pepper
1/3 cup (40g) fine cornmeal
1 tablespoon (8g) cornstarch
1/3 cup (80ml) olive oil

Notes & Substitutions: No Greek yogurt on hand? Sour cream works perfectly in the sauce. You can swap fine cornmeal for all-purpose flour in a pinch, though the cornmeal gives a superior crunch. Fresh herbs are strongly recommended, but in a real hurry, use 1 teaspoon dried parsley and 1 teaspoon dried mint as a substitute across both the sauce and fritters.

Instructions

Step 1 — Make the Garlic Herb Yogurt Sauce

In a small bowl, whisk together the yogurt (or sour cream), chopped fresh parsley, chopped fresh mint, fresh lemon juice, olive oil, honey, and garlic powder. Season with salt and freshly ground black pepper to taste. Cover and refrigerate until ready to serve — chilling allows the flavors to meld beautifully.

Step 2 — Draw Out the Moisture

Place the shredded zucchini and shredded sweet potato in a large colander. Sprinkle with 1 teaspoon of the divided salt and toss to combine. Let them sit for 10 minutes. This step is critical — it pulls excess water from the vegetables, which means crispier fritters. After 10 minutes, transfer the mixture to a clean kitchen towel or several layers of paper towels and squeeze out as much liquid as possible. Don’t skip this!

Step 3 — Build the Fritter Batter

Transfer the squeezed vegetables to a large mixing bowl. Add the finely chopped yellow onion, eggs, minced garlic, chopped fresh parsley, chopped fresh mint, black pepper, and remaining 1/2 teaspoon of salt. Stir until well combined. Add the fine cornmeal and cornstarch, then mix again until a thick, cohesive batter forms. The cornstarch acts as a binder and helps achieve that golden crust.

Step 4 — Fry the Fritters

Heat the olive oil in a large skillet over medium-high heat. The oil is ready when a small drop of batter sizzles immediately on contact. Working in batches, scoop about 2–3 tablespoons of batter per fritter into the pan and gently flatten each one with the back of a spatula. Cook for 3–4 minutes per side, until deep golden brown and cooked through. Avoid overcrowding the pan — this keeps the temperature high and ensures crispiness. Transfer cooked fritters to a paper towel-lined plate.

Step 5 — Serve

Arrange the warm fritters on a serving platter and serve alongside the chilled garlic herb yogurt sauce. Enjoy immediately for peak crispiness.

Pro Tips & Troubleshooting

Most common mistake: Not squeezing enough moisture out of the vegetables. If your fritters are falling apart or turning out soggy, excess water is almost always the culprit. Use a clean towel and squeeze firmly — you’ll be surprised how much liquid comes out.

Technique tip: Keep your skillet at a steady medium-high heat. Too low and the fritters absorb oil instead of crisping up. Too high and the outside burns before the inside cooks through.

Troubleshooting: If your batter feels too wet and loose, simply mix in an extra teaspoon of cornstarch and let it rest for 2 minutes before frying again.

Serving, Storage & Variations

Serving: Stack fritters on a board with a generous bowl of garlic herb yogurt sauce on the side. Top with extra fresh herbs and a squeeze of lemon for a beautiful presentation. They also pair wonderfully with a simple green salad.

Storage: Store leftover fritters in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium heat or in an oven at 375°F (190°C) for 8–10 minutes to restore crispiness. Avoid the microwave — it makes them soggy.

Variations:

Cheesy fritters: Stir in 1/4 cup of crumbled feta cheese into the batter for a salty, savory twist.
Spiced fritters: Add 1/2 teaspoon of cumin and a pinch of red pepper flakes for a warm, smoky kick.
Baked version: Brush fritters lightly with olive oil and bake at 425°F (220°C) for 20–22 minutes, flipping once halfway through.

Frequently Asked Questions

Can I make the fritter batter ahead of time?

Yes! You can prepare the batter up to 2 hours in advance and keep it covered in the refrigerator. Give it a quick stir before frying, as some liquid may separate.

Can I freeze these fritters?

Absolutely — these freeze really well. Place cooled fritters in a single layer on a baking sheet to freeze solid, then transfer to a freezer bag for up to 2 months. Reheat directly from frozen in a 375°F oven for 12–15 minutes.

Can I use a different type of oil for frying?

Yes, avocado oil or vegetable oil both work well as substitutes. They have high smoke points that are ideal for pan-frying at medium-high heat.
