Ideal for brunch gatherings, dinner parties, or weeknight meals, zucchini fritters are versatile, easy to make, and universally loved by kids and adults alike.

The History

The origins of zucchini fritters can be traced back to Mediterranean and Middle Eastern cuisines, where frying vegetables in olive oil has been a culinary tradition for centuries. In Greece, these are known as kolokythokeftedes, while in Italy they’re often referred to as frittelle di zucca or zucchine alla scapece. These dishes were born out of resourcefulness—using seasonal produce like zucchini at its peak during summer months and transforming it into flavorful, shareable morsels. Similarly, tzatziki sauce has deep roots in Greek and Balkan cooking, traditionally served alongside grilled meats, pita bread, or fresh vegetables. The combination of herbed yogurt with cucumber and garlic not only cools the palate but also enhances the flavor profile of fried foods. Over time, this pairing has become a staple in modern Mediterranean-inspired menus around the world, celebrated for its balance of textures and healthful ingredients.

Ingredients Breakdown

Zucchini Fritters:
Zucchini is the star ingredient—mild in flavor, high in water content, and rich in nutrients like vitamin C, potassium, and dietary fiber. Grated zucchini forms the base of the fritters, providing moisture and tenderness. To bind everything together, eggs act as a natural glue, while flour (all-purpose or gluten-free alternatives) gives structure and helps achieve that desirable crisp exterior. Finely chopped onion adds depth and a subtle sharpness, balancing the sweetness of the zucchini. Fresh herbs such as dill, parsley, or mint infuse brightness and aroma, elevating the overall taste. A pinch of salt draws out excess moisture from the zucchini, improving texture, while black pepper adds gentle heat. Optional additions like crumbled feta cheese or grated Parmesan introduce a salty, umami richness that complements the vegetables beautifully.

Tzatziki Sauce:
Tzatziki relies on thick Greek yogurt as its foundation—an excellent source of protein and probiotics. The yogurt is combined with finely grated or shredded cucumber, which must be well-drained to prevent a watery sauce. Garlic provides bold, pungent notes that define authentic tzatziki, while lemon juice imparts a zesty acidity that cuts through the richness. Extra virgin olive oil adds smoothness and depth, enhancing mouthfeel. Fresh dill or mint contribute herbal freshness, and a touch of salt rounds out the flavors. Some variations include a splash of red wine vinegar or a sprinkle of dried oregano for complexity. When properly chilled, tzatziki develops a creamy, luscious consistency that pairs perfectly with warm, crispy fritters.

Step-by-Step Recipe

1. Prepare the Zucchini: Wash 2 medium zucchinis and grate them using a box grater or food processor. Place the grated zucchini in a colander, sprinkle with 1 teaspoon of salt, and let sit for 10–15 minutes to draw out moisture. After resting, squeeze the zucchini firmly with your hands or wrap it in a clean kitchen towel and press to remove as much liquid as possible. This step is crucial for preventing soggy fritters.
2. Mix the Fritter Batter: In a large bowl, combine the drained zucchini, 1/2 cup finely chopped yellow onion, 2 large eggs, 1/3 cup all-purpose flour (or chickpea flour for a gluten-free option), 2 tablespoons chopped fresh dill, 2 tablespoons chopped fresh parsley, 1/2 teaspoon black pepper, and optionally 1/4 cup crumbled feta cheese. Stir until evenly mixed. Taste and adjust seasoning if needed.
3. Form the Patties: Using a tablespoon or small ice cream scoop, portion the mixture and shape into flat, round patties about 1/2 inch thick. Place them on a plate or tray lined with parchment paper. If the mixture feels too wet, add another tablespoon of flour gradually until it holds together.
4. Fry the Fritters: Heat 2–3 tablespoons of olive oil or avocado oil in a large non-stick skillet over medium heat. Once shimmering, carefully place 3–4 fritters at a time in the pan without overcrowding. Cook for 3–4 minutes per side, pressing gently with a spatula, until golden brown and cooked through. Transfer to a wire rack or paper towel-lined plate to drain excess oil. Repeat with remaining batter, adding more oil as needed.
5. Make the Tzatziki: While the fritters cook, prepare the sauce. Peel and grate 1 medium cucumber, then place it in a fine-mesh strainer with a pinch of salt. Let it sit 10 minutes, then squeeze out all excess liquid. In a bowl, mix the drained cucumber with 1 cup full-fat Greek yogurt, 1 minced garlic clove, 1 tablespoon lemon juice, 1 tablespoon extra virgin olive oil, 1 tablespoon chopped fresh dill, 1/4 teaspoon salt, and freshly ground black pepper to taste. Stir well, cover, and refrigerate for at least 30 minutes before serving to allow flavors to meld.
6. Serve Warm: Arrange the zucchini fritters on a platter and serve immediately with a generous dollop of chilled tzatziki on the side or drizzled on top. Garnish with extra herbs, a lemon wedge, or a sprinkle of paprika for visual appeal.

Tips

• Squeeze Thoroughly: Do not skip draining and squeezing the zucchini—it’s the key to achieving crispy fritters. Moisture is the enemy of browning!
• Use Cold Yogurt: For tzatziki, always use cold yogurt straight from the fridge to maintain thickness and prevent separation.
• Don’t Overcrowd the Pan: Cooking too many fritters at once lowers the oil temperature and leads to greasy results. Be patient and fry in batches.
• Test One First: Fry a small test patty first. If it falls apart, add more flour or an additional egg to stabilize the mixture.
• Keep Them Warm: If making a large batch, keep finished fritters warm in a 200°F (95°C) oven on a baking sheet without stacking to preserve crispiness.
• Season Gradually: Since feta and salted yogurt can vary in saltiness, season conservatively and adjust just before serving.
• Chill Before Frying (Optional): For firmer patties, refrigerate the formed fritters for 20–30 minutes before cooking.

Variations and Customizations

This recipe is highly adaptable to suit different tastes and dietary needs:

• Gluten-Free: Substitute all-purpose flour with almond flour, oat flour, or chickpea flour for a naturally gluten-free version.
• Vegan Option: Replace eggs with flax eggs (2 tablespoons ground flaxseed + 5 tablespoons water) and use dairy-free yogurt for the tzatziki.
• Add Veggies: Mix in grated carrots, bell peppers, or spinach for added color, texture, and nutrition.
• Spice It Up: Add a pinch of cayenne pepper, smoked paprika, or red pepper flakes for a spicy kick.
• Cheese Varieties: Swap feta for ricotta salata, goat cheese, or even shredded mozzarella for a milder flavor.
• Herb Swaps: Try basil, chives, or cilantro instead of dill and parsley for a unique twist.
• Baking Option: For a lighter version, bake the fritters on a greased parchment-lined baking sheet at 400°F (200°C) for 20–25 minutes, flipping halfway through.
• Air Fryer Method: Lightly spray shaped fritters with oil and air fry at 375°F (190°C) for 10–12 minutes, flipping once, until golden and crisp.

Health Considerations and Nutritional Value

Zucchini fritters with tzatziki offer a balanced profile of macronutrients and essential micronutrients. Zucchini itself is low in calories (about 17 kcal per cup) and rich in antioxidants like lutein and zeaxanthin, which support eye health. Its high water content promotes hydration, while dietary fiber aids digestion and supports gut health. Eggs provide high-quality protein and choline, important for brain function. Using whole wheat or alternative flours increases fiber content, supporting sustained energy levels. Olive oil contributes heart-healthy monounsaturated fats, known to reduce inflammation and improve cholesterol profiles.

Tzatziki sauce is a nutritious accompaniment—Greek yogurt is packed with protein and calcium, and when made with full-fat yogurt, it helps with satiety and nutrient absorption. Garlic contains allicin, a compound with antimicrobial and immune-boosting properties. Cucumber adds hydration and contains antioxidants like flavonoids and tannins. However, those watching sodium intake should be mindful of salt in both feta cheese and store-bought yogurt; opt for low-sodium versions when possible. For individuals with lactose intolerance, lactose-free yogurt or plant-based alternatives can be used successfully in tzatziki. Overall, this dish is relatively low in carbohydrates and can fit into various eating plans including Mediterranean, flexitarian, and balanced diets.
