What if a couple of humble zucchinis could turn into something crispy, cheesy, and seriously satisfying?
That’s exactly what happens with these Low Carb Zucchini Fritters.
Instead of reaching for potatoes, breadcrumbs, or regular flour, we’re turning shredded zucchini into golden little patties with a savory, cheesy center and crisp edges. They’re quick enough for a weekday lunch, tasty enough for a snack, and versatile enough to serve alongside almost any dinner.
The biggest secret to great zucchini fritters isn’t complicated seasoning—it’s getting the water out of the zucchini. Zucchini naturally holds a lot of moisture, and too much of it can leave fritters soft instead of beautifully crisp. Properly draining the shredded zucchini gives the patties a much better texture. Similar low-carb fritter recipes also rely on squeezing the zucchini well before cooking for this reason.
These crispy keto zucchini fritters are naturally gluten-free when you use certified gluten-free ingredients, and zucchini is a popular low-carb vegetable choice.
They’re also incredibly easy to customize. Add garlic, Parmesan, cheddar, fresh herbs, green onions, or a pinch of red pepper flakes. Serve them with sour cream, ranch, garlic yogurt sauce, or avocado dip.

How to Make This Crispy Keto Zucchini Fritters
Step 1: Shred the Zucchini
Wash 3 medium zucchinis and trim off the stem ends. Use the coarse box grater holes or a food processor shredding disk to grate the squash into long strands. Place all the shredded zucchini into a large mixing bowl.
Step 2: The Moisture Extraction Salt Sweat
Toss the shredded zucchini with 1 teaspoon of sea salt until evenly distributed. Let the salted zucchini sit undisturbed at room temperature for 10 minutes. As it sits, the salt draws out pools of trapped liquid from inside the cell walls of the squash.
Step 3: Wring it Bone-Dry
Transfer the sweated zucchini into a clean, thin tea towel or double-layered cheesecloth. Gather the corners together, twist tightly over the sink, and squeeze vigorously with your hands. Squeeze multiple times until no more liquid drips out. The Pro Secret: Do not rush this step! You should extract roughly 1 cup of green juice. The drier your zucchini strands are, the crispier your final fritters will be.
Step 4: Mix the Batter Base
In a separate medium bowl, whisk together 2 large eggs, 1/4 cup crumbled feta, 1/4 cup shredded mozzarella, 2 minced garlic cloves, 2 chopped scallions, 1/4 cup chopped parsley, 1/4 teaspoon black pepper, 1/4 teaspoon garlic powder, and 1/4 teaspoon chili powder. Add the squeezed, dried zucchini strands to the egg mixture and stir to break up any packed clumps.
Step 5: Incorporate the Flour
Slowly dust 1/2 cup of superfine almond flour over the bowl. Fold the mixture together with a silicone spatula until a thick, cohesive batter forms. Let the batter rest for 3 minutes so the almond flour can absorb remaining surface moisture.
Step 6: Pan-Fry to Golden Perfection
Heat 1 to 2 tablespoons of avocado oil or olive oil in a large non-stick skillet or cast-iron pan over medium-high heat. Scoop 1/4-cup portions of batter into the hot oil. Use the back of a spatula to gently press each scoop down into a 1/2-inch thick disk. Cook for 3 to 4 minutes without moving them, until the undersides are deep golden brown. Carefully flip with a thin spatula and fry for another 3 minutes on the second side.
Step 7: Drain and Serve Hot
Transfer cooked fritters onto a plate lined with paper towels to absorb any extra oil on the surface. Repeat with remaining batter, adding a splash of oil to the pan as needed. Serve immediately while hot and crunchy!
Cooking Variations
- For Air Fryer Low Carb Zucchini Fritters: Preheat your air fryer to 375°F (190°C). Line the basket with perforated parchment paper or spray generously with avocado oil. Scoop patties into the basket in a single layer without crowding. Lightly spray the tops with oil spray. Air fry for 8 minutes, flip gently, spray again, and cook for 4 to 5 minutes more until crisp and golden.
- For Oven Baked Zucchini Fritters: Preheat your oven to 400°F (200°C) and line two large baking sheets with parchment paper. Spray paper with non-stick spray. Scoop batter onto sheets, flatten into disks, and spray the tops. Bake for 20 minutes, carefully flipping halfway through, until edges are brown and firm.
Pro Tips for Best Recipe
Use a Non-Stick or Cast-Iron Pan: Low-carb batters lack traditional wheat gluten, making them delicate during the flip. A high-quality non-stick pan or well-seasoned cast iron skillet prevents sticking entirely.
Don’t Overcrowd the Skillet: Cook fritters in batches of 3 or 4 at a time. Crowding the pan drops the oil temperature and traps steam, turning your crisp edges soggy.
Grater Size Matters: Shred your zucchini on the coarse side of a grater. Powder-fine grating releases too much liquid, while thick slices won’t bind smoothly into a patty.
Heat the Oil First: Always wait until your pan oil shimmers before adding the batter. Cold oil soaks directly into the almond flour instead of immediately searing the outer crust.
Storage
- To Store: Let cooked fritters cool down to room temperature. Place them in an airtight container with sheets of parchment paper placed between the layers to keep them from sticking. Refrigerate for up to 4 days.
- To Freeze: Arrange cooled fritters on a baking sheet in a single layer and freeze for 1 hour until solid. Transfer frozen patties to a freezer-safe zip-top bag for up to 3 months.
- To Re-Crisp: Avoid microwaving, which renders fritters soft and gummy. Reheat stored fritters in an air fryer at 350°F (175°C) for 3 to 4 minutes, or crisp them in a hot skillet with a tiny drop of oil.
Frequently Asked Questions
Why are my zucchini fritters falling apart in the pan?
Fritters break apart when there is too much liquid left in the zucchini or if the pan isn’t hot enough. Make sure to squeeze out all excess moisture with a tea towel and ensure the eggs and almond flour are fully incorporated as binders.
Can I substitute coconut flour for almond flour?
Yes, but do not use a 1:1 ratio! Coconut flour absorbs liquid rapidly. If using coconut flour, reduce the amount from 1/2 cup of almond flour to just 2 or 3 tablespoons.
What dips go best with low carb zucchini fritters?
These savory, garlic-herb patties pair wonderfully with cold sour cream, Greek yogurt, homemade tzatziki, garlic aioli, or creamy ranch dressing.
Can I make the batter ahead of time?
It is best to fry fritters immediately after mixing the batter. If the batter sits in the fridge for hours, the salt continues drawing moisture out of the zucchini, turning the mix watery.

Ultimate Crispy Keto Zucchini Fritters
Ingredients
- The Vegetable Base
3 medium fresh zucchinis (shredded; approx. 1 lb)
1 tsp coarse sea salt (for sweating water)
- The Cheesy Low-Carb Batter
2 large eggs (beaten)
¼ cup crumbled feta cheese
¼ cup shredded mozzarella cheese
½ cup superfine blanched almond flour
2 cloves garlic (minced)
2 scallions (finely chopped)
¼ cup fresh parsley (finely chopped)
¼ tsp black pepper
¼ tsp garlic powder
¼ tsp chili powder
2 tbsp avocado oil or olive oil (for pan frying)
Instructions
Grate zucchinis finely into a bowl. Toss with 1 tsp sea salt and rest for 10 minutes to sweat out internal water.
Wrap zucchini in a clean towel and squeeze tightly over the sink until no more water drains out.
Whisk eggs, cheeses, garlic, scallions, parsley, and seasonings together. Stir in the dried zucchini, then fold in almond flour until a cohesive mix forms.
Heat oil in a skillet over medium-high heat. Scoop 1/4-cup portions into the hot oil and flatten into patties. Cook 3 to 4 minutes per side until deep golden and crispy.
Transfer onto paper towels briefly, then serve hot with sour cream or tzatziki.
Notes
Squeeze Firmly: Getting rid of moisture is the single most important step for crispy results. Don’t Overcrowd: Leave space between patties in the skillet so they fry rather than steam. Cheese Selection: Feta and mozzarella deliver the ultimate combination of tangy flavor and meltable texture. Cook on Medium-High: High heat sears the outer almond crust quickly without overcooking the inside. Reheat Smart: Crisp up leftovers in an air fryer or pan—never the microwave!
