Keto Avocado Fries in the Air Fryer

I coat thick avocado slices in a crispy pork rind and almond flour breading, then air fry them until they crackle on the outside and stay creamy inside. This low carb side dish is my go-to for burger night.
I started making these because I wanted a crispy side dish that actually felt like fries, not a sad imitation of the real thing. The pork rind and almond flour breading is what makes them work. It crisps up the way regular breadcrumbs never could, and the avocado inside stays rich and creamy without turning to mush.
The trick I figured out after testing this a bunch of times: use avocados that are slightly underripe. If they’re fully soft, the slices fall apart during breading. You want firm enough to hold a clean 1/4 inch slice, with just a little give when you squeeze. That firmness keeps everything intact through the double coating process and the high heat.
I double-coat each slice: almond flour mixed with cajun seasoning first, then egg wash, then seasoned ground pork rinds. The cajun blend adds a warmth you won’t get from plain breading, and the double layer means the coating actually sticks instead of sliding off during cooking. Into the air fryer at 400 degrees for about 12 minutes total, flipping halfway through. The edges get golden and almost crackle when you bite in. A light spray of avocado oil right before they go in makes a real difference in how evenly everything crisps up.
At 1.9g net carbs per serving, these fit comfortably into a keto day. But honestly, that’s not why my family keeps requesting them. To them, this is just a good side dish. We serve them next to hamburger buns stuffed with smash burgers, or alongside fried pickles for a full appetizer spread when we have people over. The combo of creamy avocado inside a crispy shell next to a burger is the kind of meal that makes you forget you’re eating low carb.
If you’ve made my French fries, you know I take the crispy factor seriously. These avocado fries hit differently though. The avocado adds a richness that root vegetable fries just can’t match. I’ve also served them alongside jicama fries for a two-fry platter, and it went over better than I expected.
The whole process takes about 20 minutes from slicing to eating. Most of that is cooking time, and you can do it in batches if your basket is smaller. Prep is maybe 5 minutes once you get the three breading bowls lined up on the counter. I work assembly-line style, coating all the slices before any of them hit the heat. It’s the kind of side I make on a weeknight without thinking twice about it.

Step by Step Instructions
Step by Step Instructions
Slice avocado into fries
Slice your avocados into 1/4 inch slices.
Prep your three bowls
Prepare three dipping bowls for coating your avocado fries. In bowl 1, mix together almond flour, cajun seasoning, and salt. In bowl 2, whisk together eggs and water. In bowl 3, mix together ground pork rinds, garlic powder and cayenne pepper.
First, dust
Dip each avocado slice into the almond flour mixture just to coat the outside. Work in batches.
Then, dip
Dip each almond flour coated avocado slice into the egg wash and shake off the excess.
Then, dredge
Dip the avocado slice into the pork rind mixture. Repeat with remaining avocado.
Air fry
Place a layer of breaded avocado fries in the basket in the air fryer. Spray the avocado with avocado oil or olive oil. Turn air fryer to 400 degrees and air fry the avocado fries for 6 minutes. Flip and continue to air fry for an additional 6 minutes. Once done, remove the fries from the basket and repeat with other breaded avocado slices.

Can I use coconut flour instead of almond flour?
I've tested this with coconut flour and it works, but you need way less of it. Start with about 1/4 of the amount you'd use for almond flour because coconut flour absorbs so much more liquid. The texture is slightly different, a bit more delicate, but it holds together and crisps up fine. I add an extra pinch of cajun seasoning when I use coconut flour because it mutes the spice a little.
What can I use instead of pork rinds if I don't eat pork?
My preference for a pork-free version is finely crushed sunflower seeds mixed with a little parmesan. The parmesan adds that savory, salty layer you'd otherwise get from the pork rinds. I've had readers try hemp hearts too, and they work for crunch. Just season well with the garlic powder and cayenne from the recipe so you don't lose the flavor.
Can I freeze these for meal prep?
I've frozen the breaded slices before cooking and it works well. Lay them in a single layer on a parchment-lined baking sheet and freeze until solid, then transfer to a freezer bag. They keep for up to 3 months. When you're ready, cook them straight from frozen and add 2-3 extra minutes to the cook time. I don't recommend freezing them after cooking because the breading gets soggy when it thaws.
Can I bake these in the oven instead of air frying?
I've done both. The oven works, but you lose some crunch. Bake at 425 degrees on a wire rack set over a baking sheet, flipping halfway, for about 15-18 minutes. The wire rack helps circulate air underneath so the bottoms don't get soggy. I still prefer the basket method because the coating gets noticeably crispier, but the oven version is solid if that's what you have.
How long do leftovers last in the fridge?
About 2-3 days in an airtight container. The breading softens overnight but crisps right back up when reheated at 400 degrees for 3-4 minutes. I wrap mine in a layer of foil inside the container to keep moisture off the coating. Honestly though, they're best fresh. I usually only make as many as we'll eat in one sitting.
What dipping sauces go best with these?
I serve them with ranch most of the time, but they're also great with chipotle mayo or a smoky BBQ sauce. My family's favorite combo is ranch with a squeeze of lime juice mixed in. The acid cuts through the richness of the avocado, and the ranch pairs with the cajun seasoning in the breading. I've also done a simple garlic aioli when I'm feeling fancy.
How do I keep the breading from falling off?
Two things make the biggest difference. First, make sure your avocado slices are dry before they hit the almond flour. Any moisture on the surface and the coating slides right off. I pat mine with a paper towel after slicing. Second, don't rush the egg wash step. Make sure each slice gets an even coat of egg before going into the pork rind mixture. That egg is the glue that holds everything together.
If your pork rind coating keeps sliding off, the avocado is too wet before the almond flour step. Pat each slice dry with a paper towel first. The breading stays put and the crust is totally different.
Yeah, moisture is the culprit every time. Wet avocado and the almond flour just won't grip. Paper towel first, every time.
My husband doesn't eat pork, so the pork rind coating is out for us. I've tried doubling the almond flour in other keto air fryer recipes, but the crust always comes out dense instead of crispy and doesn't hold. Is there a swap that actually gets close to that crackly texture, or is the pork rind really what makes this one work?
Crushed sunflower seeds + a bit of parmesan gets surprisingly close. The parmesan covers that savory salty hit you lose without the pork rinds, and sunflower seeds actually crisp up well in the air fryer. Hemp hearts work too if that's easier to find.
One thing that made a real difference: chill the avocado slices in the freezer for about 10 minutes before coating. They firm up just enough that the pork rind crust actually stays on instead of sliding off when you transfer them to the basket. First batch I skipped this step and lost half the breading before it even hit the air fryer. The crunch you get when they come out golden is worth the extra wait. Also found 400 for 8 minutes works better than going the full cook time if your slices are closer to the 1/4 inch mark. Still creamy inside, crispy outside, no mush.
Never tried the freeze step. Cold avocado makes sense though - firmer surface means the pork rind coating actually grips instead of sliding when you transfer. Trying it.
I've tried at least four avocado fry recipes chasing real crunch, and pork rind is the only coating that actually gets there.
Four recipes to land on pork rind is about right. Nothing else actually holds the crunch. The cajun in the coating here puts it a step above plain rinds too.
My 9-year-old has refused avocado since he was a toddler. Made these, said nothing about the ingredients. He ate six and asked if we could have them again Thursday. The pork rind situation stays between me and the recipe.
Six and already locked in for Thursday. That pork rind secret is worth protecting.
I've made at least four versions of keto avocado fries trying to get the breading to hold. Most of them, two bites in and the whole thing's sliding off. The pork rind and almond flour combo here actually sticks. Real heat from the cajun and cayenne, and the creamy center holds. This is the one.
Four versions is a lot of failed breading. Patting them dry before the almond flour - that's the fix most recipes don't mention.
Made these alongside burgers last week and my son, who won't touch avocado, asked me why I'd been 'hiding this from him.' The pork rind breading crisps up in a way that completely changes the texture, creamy in the middle and almost crackling on the outside. Now they're on permanent burger night rotation.
'Why I'd been hiding this from him' made me laugh. The cajun in the breading pairs so well with burgers, that combo is underrated.
Do they need to be firm, or is fully ripe okay? Mine are pretty soft and I'm worried they'll fall apart going through all three dipping bowls.
Firm is better for this one. Fully ripe will hold through the almond flour but pressing the pork rind coating in is where soft ones fall apart. If yours are already soft, slice them and freeze for 10-15 minutes before you start breading. Takes the edge off without making them hard.
There was a food truck near my old apartment that did fried avocado and after I went keto I just accepted that was gone. Made these last Friday and the first bite hit me harder than I was ready for. The cajun breading against the creamy avocado inside is exactly what I remembered, maybe more. I'm not a confident cook at all, and somehow I nailed it on the first try. That part freaking got me as much as the taste did.
That food truck part hit. The cajun against the creamy inside was exactly what I was building toward with this one. And the pork rind crust is more forgiving than it looks, first tries usually work.
Made these for burger night and my 9-year-old, who picks avocado out of everything, ate four in a row without asking what they were. When I told her after, she did not believe me. The pork rind breading gets SO crispy in the air fryer, like actual crunch. I'm adding these to every burger night from now on.
Four in a row from a kid who avoids avocado. Pork rind does something breadcrumbs never could.
I was skeptical about breading avocado because I thought it would just get mushy, but these actually stayed firm inside with a crispy coating. Used the pork rind breading exactly as written and they came out way better than I expected. The cajun seasoning gives them a nice kick.
The avocado ripeness makes a huge difference there. Slightly underripe holds its shape way better than a fully soft one. Glad the cajun kick landed.
The pork rind coating gets so crispy. Perfect with a burger.
That's exactly what I designed them for. The pork rind breading gets crispier than regular breadcrumbs ever could.
Can't wait to make and try these.
The pork rind coating is the thing. You'll hear it crackle when you bite in.
This is amazing, can you freeze it?
I know you can freeze avocado, but I haven't tried freezing these yet.
I made these to go with hamburgers and they turned out delicious. They were so easy to throw together and cook up in the air fryer. They came out so crispy. Great recipe, thanks for sharing!!!
Burger night right there. The cajun seasoning in the breading pairs really well with beef.
