If you’re looking for a delicious way to sneak more vegetables into your keto diet, these cheddar zucchini fritters are about to become your new favorite recipe. They’re crispy on the outside, tender on the inside, and packed with cheesy goodness that’ll make you forget you’re eating healthy.
I’ve discovered that air frying these fritters gives you all the satisfying crunch of traditional pan-fried versions, without the extra oil. You’ll love how the sharp cheddar cheese melts perfectly into the zucchini, creating irresistible golden-brown patties that fit perfectly into your low-carb lifestyle. Trust me, even veggie skeptics won’t be able to resist these savory bites. Plus, they’re incredibly versatile – serve them as a side dish, snack, or even breakfast option when you’re craving something different.
Recipe

Zucchini fritters are a delightful keto-friendly alternative that transforms simple ingredients into crispy, golden patties. These low-carb bites combine fresh zucchini with sharp cheddar cheese for a satisfying snack or side dish that fits perfectly into a ketogenic lifestyle.
The air fryer method delivers perfectly crispy results without the need for excessive oil, making these fritters a healthier option compared to traditional pan-frying. The combination of almond flour and cheddar cheese creates the ideal binding structure while keeping the carb count low and adding a rich, savory flavor.
- 2 medium zucchini, grated
- 1 cup shredded cheddar cheese
- 1 large egg
- 1/2 cup almond flour
- 1/2 teaspoon salt
Grate the zucchini and squeeze out excess moisture using a clean kitchen towel. In a large bowl, combine the dried zucchini with beaten egg, shredded cheddar cheese, almond flour, and salt, mixing until well incorporated. Form the mixture into small patties approximately 3 inches in diameter. Place the patties in a single layer in the air fryer basket, leaving space between each fritter. Cook at 375°F for 12 minutes, flipping halfway through, until golden brown and crispy on both sides.
For ideal results, thoroughly dry the grated zucchini before mixing with other ingredients, as excess moisture will prevent proper crisping. If the mixture seems too wet, gradually add more almond flour, one tablespoon at a time. The fritters can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the air fryer at 350°F for 2-3 minutes to restore their crispy texture.
Prep Time
While the cooking time for these keto zucchini fritters is relatively quick, you’ll want to set aside about 20-25 minutes for preparation. The bulk of your prep time will be spent grating the zucchini and removing its moisture, which is essential for achieving that perfect crispy texture.
You’ll need about 10 minutes to grate your zucchini and squeeze out the excess water. Then, give yourself another 5 minutes to shred the cheddar cheese (if it’s not pre-shredded) and measure out your other ingredients. The final 5-10 minutes will be spent mixing everything together and forming your fritters into uniform patties. Don’t rush this last step – well-shaped patties will cook more evenly and look more appetizing when served.
Equipment needed
Once you’ve gathered your ingredients, let’s look at what you’ll need to make these fritters come to life. You’ll need a reliable air fryer with a basket that’s at least 4 quarts in capacity, plus a box grater or food processor for shredding the zucchini. Don’t forget to grab a clean kitchen towel or cheesecloth – it’s essential for squeezing out excess moisture.
You’ll also want to have these tools handy:
- Large mixing bowl
- Measuring cups and spoons
- Spatula for mixing
- Small ice cream scoop or 1/4 cup measure for portioning
- Tongs for flipping the fritters
- Paper towels for draining
- Airtight container for storage
Trust me, having everything ready before you start will make the process so much smoother!
Basic Cooking Method and Time
The basic cooking steps for these keto fritters couldn’t be simpler – I’ve tested them dozens of times to get the timing just right. First, you’ll set your air fryer to 375°F and let it preheat while you form your patties. I’ve found that making them about 3 inches wide creates the perfect crispy-to-tender ratio.
Place the fritters in your air fryer basket, making sure they aren’t touching each other. I usually cook them for 12 minutes total, flipping halfway through at the 6-minute mark. You’ll know they’re done when they’re golden brown on both sides and crispy to the touch. Trust me, that satisfying crunch when you bite into them is worth the wait! If you need to cook in batches, keep the first batch warm in your oven at 200°F.
Cooking Steps
Let me walk you through the step-by-step process for making these irresistibly crispy fritters. First, you’ll want to grate your zucchini using a box grater or food processor. Here’s a tip I learned the hard way – don’t skip the essential step of squeezing out that excess moisture!
Mix your dried zucchini with the beaten egg, making sure it’s well combined. Next, fold in your shredded cheddar (I love watching it create those stringy cheese pulls) and almond flour. Season with salt, then form small, even-sized patties about 3 inches wide. They should feel firm but not too packed.
Place them in your air fryer basket with some breathing room between each fritter. Set your temperature to 375°F and cook for 12 minutes, flipping halfway through for that perfect golden-brown finish.
Step 1. Grate and Press Zucchini Dry

Properly grating and drying your zucchini makes all the difference between soggy and perfectly crispy fritters. Start by trimming the ends off your zucchini, then run it along a box grater’s large holes, watching your fingers as you go. I’ve learned from experience that grating zucchini can be quite the water show!
Now comes the vital part – removing that excess moisture. Place your grated zucchini in the center of a clean kitchen towel and gather the edges together. Over your sink, twist and squeeze the towel as hard as you can. You’ll be amazed at how much water comes out! Keep squeezing until barely any liquid drips from the towel. This step might seem tedious, but trust me, it’s worth every squeeze for achieving those perfectly crispy fritters.
Step 2. Mix Ingredients Until Combined

Mixing your keto fritter ingredients together couldn’t be simpler, but there’s definitely a method to getting that perfect consistency. Once you’ve thoroughly dried your grated zucchini, add it to a large mixing bowl along with your beaten egg, shredded cheddar, and almond flour. I like to sprinkle the salt evenly over everything before mixing.
Using clean hands or a sturdy spatula, fold all ingredients together until you’ve got a uniform mixture. You’ll know it’s ready when the cheese and almond flour are evenly distributed throughout, with no dry patches remaining. If your mixture feels too wet, don’t panic – just add almond flour one tablespoon at a time until it holds together when you form a test patty. You want it moist enough to stick together but firm enough to handle.
Step 3. Shape Into Small Patties

Scooping the perfectly mixed fritter batter with your hands, you’ll want to form small, evenly-sized patties about 3 inches in diameter and ½ inch thick. The key is maintaining consistency in size so they’ll cook evenly in your air fryer. Trust me, I’ve learned from experience that uneven patties lead to some being overcooked while others stay undercooked.
Wet your hands slightly before shaping each patty – this prevents the mixture from sticking to your fingers. Gently press the edges to guarantee they’re smooth and compact, which helps prevent breaking during cooking. If you’re batch-cooking, you can place the shaped patties on a parchment-lined baking sheet until you’re ready to air fry them. Don’t stack them, though, or they’ll stick together!
Step 4. Place in Air Fryer Basket

Transfer your shaped fritters into the air fryer basket with care, arranging them in a single layer about an inch apart. I’ve found that overcrowding the basket leads to uneven cooking, so you’ll want to work in batches if needed. The space between each fritter allows hot air to circulate properly, creating that perfectly crispy exterior we’re after.
You’ll notice that a 6-quart air fryer typically fits 4-5 fritters comfortably at a time. If your fritters are sticking to the basket, try giving it a quick spritz with avocado oil spray first – it’s my go-to trick for hassle-free removal later. Remember to place them presentation-side down initially, as the first side that cooks will usually look the most attractive.
Step 5. Flip Fritters Halfway Through Cooking

Once your fritters have cooked for about 6 minutes, you’ll need to give them a careful flip to guarantee even browning on both sides. I’ve found that using silicone-tipped tongs works best for this step, as they won’t scratch your air fryer basket or break the delicate fritters.
When you’re flipping them, you’ll notice the tops have started to set and the edges are turning golden brown – that’s exactly what you want to see. Take care not to rush this process, as hasty flipping can cause the fritters to break apart. If any bits of cheese have melted onto the basket, don’t worry about it. Just gently work your tongs under each fritter and flip with confidence. You’ll be rewarded with perfectly crispy, evenly cooked fritters every time.
Customization Options
These keto zucchini fritters serve as a perfect base for countless variations, and I love experimenting with different flavor combinations. When I’m craving something spicy, I’ll add diced jalapeños and pepper jack cheese instead of cheddar. For a Mediterranean twist, you can mix in crumbled feta, fresh oregano, and minced garlic.
I’ve found that herbs like dill, basil, or chives add wonderful depth to the base recipe. You’re not limited to zucchini either – try mixing in other low-carb veggies like cauliflower rice or shredded Brussels sprouts. For extra protein, I sometimes fold in crispy bacon bits or leftover rotisserie chicken. Just remember to maintain the same ratio of wet to dry ingredients when customizing, and you’ll have perfect fritters every time.
Ingredients list (with precise measurements)

Building on all those creative variations, let’s get down to the exact measurements you’ll need for the basic recipe. You’ll want to gather these core ingredients before you start:
- 2 medium zucchini (about 2 cups when grated)
- 1 cup shredded sharp cheddar cheese
- 1 large egg, beaten
- 1/2 cup almond flour
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper (optional)
I’ve found through trial and error that these proportions create the perfect balance of texture and flavor. The key is using medium-sized zucchini – if they’re too large, you’ll end up with excess moisture that can make your fritters soggy. Trust me, I learned this the hard way when I tried using those giant summer squash from my garden!
Storage Information
While freshly made zucchini fritters taste best right off the air fryer, I’ve found they store surprisingly well when you follow a few simple guidelines. You’ll want to let them cool completely before placing them in an airtight container – I like using glass containers with snap-on lids. They’ll keep nicely in your refrigerator for up to 3 days.
When you’re ready to enjoy your leftover fritters, don’t microwave them – they’ll turn soggy! Instead, pop them back in your air fryer at 350°F for 2-3 minutes. I’ve discovered this method brings back that wonderful crispy exterior while keeping the inside tender. If you’d like to freeze them, separate layers with parchment paper and store them for up to 2 months. Just thaw overnight in the fridge before reheating.
Health Benefits or Special Features
Since adopting a keto lifestyle, I’ve come to appreciate how these zucchini fritters pack an impressive nutritional punch without the carbs. You’ll love that each fritter delivers essential nutrients while keeping your body in ketosis. The zucchini provides vitamin C, potassium, and fiber, while the cheddar cheese adds calcium and protein to your diet.
What makes these fritters special is their versatility. I’ve served them as appetizers, side dishes, and even breakfast items topped with a fried egg. You’re getting about 3g net carbs per serving, making them perfect for your keto meal plan. Plus, the air fryer method means you’ll consume less oil than traditional frying, while still enjoying that satisfying crunch you crave on a low-carb diet.
Prep Time
Before you start cooking these delicious fritters, you’ll need about 15 minutes of prep time to get everything ready. The most time-consuming part is properly grating and drying the zucchini, which typically takes 8-10 minutes. Trust me, don’t skip the drying step – it’s essential for crispy results!
While your grated zucchini is draining, you can use those few minutes to shred the cheddar cheese and measure out your other ingredients. The actual mixing process is quick, taking only about 3-4 minutes to combine everything thoroughly. Shaping the mixture into fritters is the final prep step, and you’ll need just 2-3 minutes to form them into evenly-sized patties. Once that’s done, you’re ready to start air frying!
Cook Time
The total cook time for these crispy keto zucchini fritters is about 12-15 minutes in your air fryer. You’ll want to cook them at 375°F, flipping halfway through to guarantee even browning on both sides. I’ve found that six minutes per side usually does the trick, but you might need to adjust the timing slightly depending on your air fryer model.
Watch for that golden-brown color – it’s your best indicator of doneness. You’ll know they’re ready when the edges are crispy and the cheese has melted into delicious little browned spots. Don’t overcrowd the basket; work in batches if needed to maintain proper air circulation. For extra-crispy results, I sometimes add an extra minute or two of cooking time, but keep a close eye to prevent burning.
Total Time
When planning to make these keto zucchini fritters, you’ll want to set aside about 30 minutes from start to finish. This includes roughly 15 minutes of prep time, where you’ll grate the zucchini and squeeze out the moisture, plus another 15 minutes for mixing ingredients and air frying.
I’ve found that you can save time by grating the zucchini while your air fryer preheats. The actual hands-on work isn’t too demanding – you’ll spend most of your active time squeezing out moisture and shaping the patties. Once they’re in the air fryer, you’re free to prep other parts of your meal or clean up your workspace. Trust me, these 30 minutes are well worth it when you taste these crispy, cheesy fritters hot from the air fryer!
Yield
This recipe yields approximately 8-10 medium-sized fritters, which I’ve found is perfect for serving 3-4 people as a side dish or appetizer. If you’re planning to make these as a main course, I’d recommend doubling the recipe since they’re quite addictive, and everyone will want seconds!
Each fritter is about 3 inches in diameter when properly formed, giving you a satisfying portion that’s filling without being heavy. I’ve noticed that when I serve these at gatherings, they disappear quickly, so you might want to plan accordingly. You can easily scale the recipe up or down – just maintain the same ratios of ingredients. For a larger crowd, I often make a double batch and keep them warm in the oven at 200°F until serving time.
Final Thoughts
Making these keto zucchini fritters in my air fryer has revolutionized how I enjoy low-carb cooking, and I’m confident you’ll love them too. The combination of crispy edges, melty cheddar, and tender zucchini creates an irresistible snack that’ll keep you coming back for more.
Don’t be discouraged if your first batch isn’t perfect – getting the moisture level right takes a bit of practice. I’ve found that letting the grated zucchini drain for an extra few minutes makes all the difference. Once you’ve mastered these fritters, you’ll have a versatile dish that works great as an appetizer, side dish, or quick lunch. Trust me, even your non-keto friends will be asking for the recipe!
