Crispy Gluten-Free Zucchini Fritters Recipe

Stack of crispy gluten-free zucchini fritters served on a white plate, topped with sour cream and sliced green onions.

These gluten-free zucchini fritters are golden and crisp on the outside, tender and flavorful inside, and ready in well under an hour. They combine grated zucchini, parmesan, green onion, and a simple gluten-free batter. Squeezing the zucchini thoroughly to remove excess moisture is the single most important step for getting the fritters to crisp. You can pan fry for the best texture, or bake or air fry for a lighter finish.

Why You’ll Love this Recipe

  • Three cooking methods: Pan fry for the crispiest fritters, or bake or air fry if you prefer less oil. All methods work well with the same batter.
  • Quick to prepare: Active time is short; the rest time for the salted zucchini is about 15 minutes, and the actual cooking per batch takes only a few minutes.
  • Versatile side or snack: These pair easily with chicken, fish, steak, or a simple salad and also make a satisfying brunch when topped with a fried egg.

When zucchini is abundant in summer, this is a go-to side dish because it’s simple to assemble and can be scaled up easily.

Ingredient Notes

  • Zucchini: Use about 2 lbs (roughly 3–4 medium zucchini) grated on the large holes of a box grater. Keep the skin for texture and color. Salt, rest, and squeeze to remove as much water as possible.
  • Parmesan: Finely grated parmesan (a microplane works well) melts into the batter for savory flavor without adding excess moisture.
  • Gluten-free flour: A 1-to-1 gluten-free baking flour substitutes for all-purpose flour and helps the fritters hold together. Measure carefully for best results.
  • Cornstarch: Adds extra crisping power to the exterior when frying.
  • Green onions: Thinly sliced for a fresh, mild onion flavor that complements the zucchini.

How to Squeeze Zucchini for Crispy Fritters

After grating the zucchini, toss it with about 1 teaspoon of kosher salt and let it sit for 15 minutes. The salt draws out moisture; you’ll see liquid collect in the bowl. Transfer the grated zucchini to a clean kitchen towel, wrap it up, and squeeze firmly over the sink. Press repeatedly until the zucchini feels like damp paper shreds and no more liquid comes out. If you stop too soon the fritters will be wet and soft rather than crisp.

Recipe FAQs

Can I use a different cheese?
Yes. Aged cheddar or crumbled feta are good alternatives. Choose a flavorful cheese that isn’t too moist so the batter remains firm. The cheese can also be omitted.

Can I make these in the air fryer?
Yes. Lightly spray the air fryer basket, add flattened scoops of batter, and cook at 375°F for about 12–14 minutes, flipping halfway and spraying with oil as needed for browning.

Can I bake instead of pan frying?
Yes. Bake on a parchment-lined sheet at 400°F for 20–25 minutes, flipping halfway. They won’t be quite as crisp as the stovetop version, but they will brown and hold together well.

Expert Tips

  • Squeeze harder than you think you need to. The drier the zucchini, the crispier the fritters will be.
  • Don’t crowd the pan. Fry 3–4 fritters at a time so the oil temperature stays steady and the fritters crisp instead of stewing.
  • Wait to flip. Flip when the edges are set and the bottom releases easily—usually about 3–4 minutes. If they stick, give them another minute before turning.

Storage Instructions

These fritters are best served fresh, but you can store leftovers:

  • Refrigerator: Keep cooled fritters in an airtight container for up to 3 days.
  • Freezer: Freeze in a single layer on a baking sheet, then transfer to a freezer bag or airtight container with parchment between layers for up to 2 months.
  • Reheating: Re-crisp in a 375°F oven for 10–15 minutes or air fryer at 375°F for 5–7 minutes. Microwaving makes them soft and limp.

Serving Suggestions

Serve warm with sour cream or plain Greek yogurt mixed with a little lemon juice and dill. These fritters complement grilled or roasted proteins and work well as part of a casual summer meal. For brunch, top a fritter with a fried or poached egg. They also pair nicely with a simple green salad or roasted vegetables.

Gluten-Free Zucchini Fritters

These fritters are made with grated zucchini, gluten-free flour, eggs, parmesan, green onions, and seasonings. Follow the steps below for pan frying, or use the baked or air-fryer options in the notes.

Times & Servings

  • Prep time: 20 minutes (includes 15-minute resting time for the zucchini)
  • Cook time: 15 minutes
  • Resting time: 15 minutes
  • Total time: about 50 minutes
  • Servings: about 12 fritters

Ingredients

  • 2 lbs (907 g) zucchini, grated (skin on)
  • 1 teaspoon kosher salt (for zucchini)
  • 2 large eggs (about 100 g)
  • 2/3 cup (95 g) gluten-free 1-to-1 baking flour
  • 1/3 cup (25 g) finely grated parmesan
  • 1/4 cup (11 g) sliced green onions
  • 2 tablespoons (16 g) cornstarch
  • 1 teaspoon (4 g) baking powder
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon ground black pepper
  • 1/4 cup (56 g) oil for frying (avocado or vegetable oil)

Instructions

  1. Place the grated zucchini in a large bowl, toss with 1 teaspoon kosher salt, and let sit for 15 minutes to draw out moisture.
  2. Transfer the zucchini to a clean kitchen towel, wrap, and squeeze firmly over the sink until no more liquid comes out and the zucchini feels like damp paper shreds.
  3. In a large bowl, combine the squeezed zucchini with the gluten-free flour, eggs, finely grated parmesan, sliced green onions, cornstarch, baking powder, 1/2 teaspoon salt, garlic powder, and black pepper. Stir until evenly combined—the batter should be thick and scoopable.
  4. Heat the oil in a large skillet over medium heat. The oil is ready when a small drop of batter sizzles on contact.
  5. Working in batches of 3–4, scoop about 2–3 tablespoons of batter per fritter into the pan and gently flatten with the back of a spatula. Do not crowd the pan.
  6. Cook for 3–4 minutes until the edges look set and the bottom is deep golden. Flip and cook a further 2–3 minutes until golden on the second side. If fritters stick, give them another minute before attempting to flip.
  7. Transfer cooked fritters to a wire rack or paper towel-lined plate. Season with flaky salt if desired and serve warm with sour cream or Greek yogurt.

Notes

  • Zucchini tip: Removing moisture is essential—squeeze until nearly dry for best crispiness.
  • Baking option: Arrange fritters on a parchment-lined sheet, brush or spray with oil, and bake at 400°F for 20–25 minutes, flipping halfway.
  • Air fryer option: Lightly oil the basket, place flattened fritters inside, and cook at 375°F for about 12–14 minutes, flipping halfway and spraying with oil as needed.
  • Reheating: Re-crisp in a 375°F oven for 10–15 minutes or air fryer at 375°F for 5–7 minutes. Avoid microwaving to maintain texture.
