Salty Parmesan edges and a little lime give these thin avocado chips their flavor. Blend, flatten and bake at 325°F, then let them firm up on the tray. The nutrition estimate is 0.5g net carbs per chip when the batch makes 15 equal chips.
Ripe avocado and grated Parmesan bake into thin, golden chips with garlic, lime and a little cayenne. The cheese brings the salty crunch, while the avocado blends into the base. There are no potatoes or flour in this recipe.
Plan on about 5 minutes of prep and 30 minutes in the oven, followed by 5-10 minutes of cooling. Spread the mixture thinly and evenly so the centers have a chance to crisp before the edges get too dark.
These are best eaten fresh. Serve them on their own or with a spoonful of keto hummus or 7-layer taco dip; thin chips can be delicate with a heavy scoop of dip. For more cheesy snacks, try homemade Cheez-Its.
Baked Avocado Chips with Parmesan
The Parmesan provides much of the flavor and crisp edge. Use the full 3/4 cup in the base recipe, with a ripe avocado that blends smoothly. The teaspoon of lime adds brightness against the salty cheese.
Net Carbs Per Chip
The recipe estimate is 38 calories, 1.2g total carbs and 0.5g net carbs per serving, based on 15 equal chips. If your batch makes fewer, larger chips, each one represents more of the recipe. Avocado size and the cheese you use also affect the estimate.
Best eaten fresh
Serve these after their short cooling rest for the best crunch. Refrigerate extras in a covered container within 2 hours (1 hour above 90°F) and use within 3 days. They may soften in storage; a crisp surface does not establish that avocado-and-cheese chips are shelf-stable.
Tips for thin, crisp chips
Blend until smooth. A ripe avocado is easier to spread evenly; discard any spoiled fruit.
Flatten evenly. Thick centers take longer to bake than thin edges.
Watch the color. Aim for golden edges, not dark brown. Lime adds flavor but cannot undo a burnt chip.
Let them rest. Give the chips 5-10 minutes on the tray before trying to lift them.
Seasoning ideas
For a variation, try a small pinch of smoked paprika or Italian seasoning. Start lightly, especially with seasoning blends that contain salt, since Parmesan is already salty. Keep the avocado-to-cheese amounts the same while adjusting the seasoning.
How to make baked avocado chips
Blend the avocado, Parmesan, lime juice and seasonings until smooth. Divide into about 15 equal spoonfuls on parchment, leaving space between them, and flatten with an oiled spoon. Bake at 325°F for about 30 minutes, watching near the end for golden edges. Leave the chips on the tray for 5-10 minutes before lifting them.
Add all ingredients to the food processor and pulse until combined and smooth.

Scoop and press
Divide the mixture into about 15 equal spoonfuls on a parchment-lined baking tray. Flatten each spoonful into a thin, even round with the back of a spoon or spatula lightly coated with cooking oil. Leave about 2 inches between the rounds; use another tray if needed.
4
Bake
Bake at 325°F for about 30 minutes, until crisp and golden. Watch closely toward the end so the edges do not burn. Let cool on the tray for 5-10 minutes to firm up before lifting. Thickness and oven differences can change the baking time.

Frequently Asked Questions
How many chips does one batch make?
Aim for 15 equal chips. One serving is 1/15 of the batch, so the per-chip nutrition applies when you make 15. Larger or smaller chips change the portion size.
Can I use a different cheese?
The base recipe uses grated Parmesan. A different cheese can change spreading, browning and crispness; it is a variation rather than an identical replacement.
Can I make these dairy-free?
This recipe contains Parmesan. Nutritional yeast is not a confirmed one-for-one replacement for the cheese, so the same 3/4-cup substitution should not be treated as a tested dairy-free version.
How do I store leftover chips?
Let them firm up briefly on the tray, then refrigerate extras in a covered container within 2 hours, or 1 hour above 90°F. Use within 3 days. They are best fresh and may soften in the fridge; do not store the batch at room temperature for days.
Can I make these in an air fryer?
The documented method is the 325°F oven bake. There is no confirmed air-fryer time for this recipe; basket airflow and the thin mixture need a separate method.
Why are my chips bitter or too dark?
Check for burnt edges and use a ripe, unspoiled avocado. Spread the chips evenly and watch closely near the end of baking. Lime balances the flavor but does not guarantee that baked avocado will never taste bitter.
What can I serve with these?
They are salty and cheesy on their own. Add salsa or a small spoonful of dip if you like; thin chips can break under a heavy scoop.
Are these the same as avocado oil chips?
These chips are made with avocado flesh and Parmesan. A packaged chip labeled avocado oil may have a different base ingredient, so check its ingredient list and nutrition panel rather than assuming the same carb count.
Hi Annie, your snack recipes have been saving me lately! This is the first avocado chip I’ve had come out actually smooth, and I think it’s the food processor doing the work instead of a fork. Such a difference!
My earlier reply overstated that substitution. Nutritional yeast is not a confirmed one-for-one replacement for Parmesan here, and I cannot promise the same crispness or structure without the cheese.
The 0.5g net carbs is what got me batching these every week, but the cooling window is where people go wrong. Pulled mine early on the second batch and they were bendy half the afternoon. Ten minutes minimum, closer to fifteen if your pan is full. They’ll snap when they’re ready. Three days in a sealed container with a paper towel underneath they’re still good. Day four they go soft. Anything past two avocados and the food processor mixture gets too loose, chips spread thin and bake unevenly. Two at a time, multiple rounds. Takes longer but it works. Good recipe with a real ceiling on scaling. Annie, I almost skimmed that cooling line and it’s genuinely the whole thing.
I figured the avocado was just going to melt into the parmesan and I’d have cheesy discs. Something about the food processor step makes it hold. Crunchier from the oven than anything keto in a bag.
Don’t pull them early. First batch I was impatient and ate a few warm, bendy and kind of gross, nothing like a chip. Came back to the second tray after picking up my kid and they had an actual snap. The 30 minutes is not even the whole job.
Wasn’t sure lime zest would add anything the juice didn’t. I threw some in on batch six. It holds through the full 30 minutes in the oven where the juice just bakes out. Keeps a sharper citrus edge on the finished chip.
Making these for a get-together this Saturday so I need like triple the batch (we’ve got a crowd), does more avocado mixture per pan change the 30 minute bake time or should I just do multiple sheets?
I press the batter thinner than the recipe implies. Made a real difference. The tablespoon scoop goes further than you’d expect: I spread mine to about an eighth of an inch and the chips come out with actual snap rather than a thick avocado bite. My husband went through the ingredient list afterward because he thought I’d mixed in something he wasn’t expecting (he has strong opinions about avocado, or against it, mostly). The parmesan is the flavor engine; the avocado gives you structure and moisture but mostly disappears in the final chip. Quarter teaspoon of cayenne is pretty subtle; I nudged mine a bit higher and that’s where it landed for us. Use parchment: the bottom crisps better on it than on bare metal.
Romano instead of parmesan if you want sharper, saltier chips. Ran out mid-batch one day, grabbed what was in the fridge, fully expecting to ruin a perfectly good avocado. Came out the same, same snap and texture, but the flavor’s more aggressive, which I actually prefer now. One thing though: Romano browns faster than parmesan, so watch the edges around the 25-minute mark and pull them a little early. They firm up as they cool. Ran them through my nutrition app, still 0.5g net carbs. Doing Romano only now.
Thanks for reporting how Romano worked for you. The recipe is written for Parmesan, so I cannot promise the same browning time or nutrition with that swap.
Three ripe avocados going south so I just doubled the batch, figured I’d see how long the crunch actually held. Two days in a sealed pantry container and they were still snapping. That surprised me. The food processor step is fast enough that scaling doesn’t add much time, and that’s usually the thing that kills batch cooking for me.
Glad you enjoyed them. For storage, refrigerate extras promptly and use within 3 days. A paper towel may absorb moisture, but it does not make the batch shelf-stable.
One thing I wish someone had mentioned before my first batch: do not rush pulling them off the parchment. I did, and they fell apart. The full 5-10 minute rest is when they actually firm up and lift clean. The other thing that matters more than I expected is avocado ripeness. I made a batch with one that was still a little firm in the center, not fully ripe, and the mixture didn’t blend nearly as smooth in the food processor. The chips came out denser and took longer to crisp. The batches where I use a very ripe avocado, the kind that mashes almost velvet-smooth, spread thin and come out with those golden, slightly lacey edges. If yours aren’t crisping up the way you want, the avocado is usually why.
Yeah, ripeness is the variable I didn’t call out clearly enough in the recipe. A barely ripe avocado makes a denser chip that takes forever to crisp. The almost-too-soft ones are what get you those thin, lacy edges.
Went in doubtful that something baked at 325 for 30 minutes could actually get crispy, but these have a real snap to them that I haven’t gotten from any other low-carb chip recipe I’ve tried. Four stars because mine needed closer to 35 minutes, but the texture once they cooled was genuinely worth the wait.
Making these for a potluck next weekend and need to at least triple the batch. Does the 30-minute bake time still hold with multiple trays, or do I need to add time? And can all the trays go in at once, or does rotating matter for even crispness?
Use separate trays with space between the chips. Multiple trays can change the bake time; rotate their positions if they are browning unevenly, and judge each tray separately rather than adding a fixed number of minutes.
The lime adds brightness, but it does not guarantee the avocado will not taste bitter. Watch for overbrowned edges and start with a ripe, unspoiled avocado.
I used to have this thing where I’d come home from work on Fridays and eat chips straight from the bag until dinner. Tortilla chips mostly. Just the ritual. Keto killed that and I didn’t really mourn it until I smelled these coming out of the oven (the parmesan goes almost nutty, which I was not expecting). I stood there eating them off the pan before they cooled, which is exactly what I used to do with a bag of Tostitos, and for a second it just felt the same. Mine were done closer to 28 minutes at 325 and the crunch was right, the kind that actually crumbles when you bite down. The lime is subtle but it’s what keeps them from tasting like a vegetable snack in disguise. Four stars because they soften if you leave them out, so eat them fresh. Not a problem in practice.
Thanks for sharing your timing. Ovens and chip thickness can change it, and these are best after their short cooling rest. Refrigerate extras rather than leaving them out for days.
I’ve been cooking for years but I’m brand new to keto. Avocado chips sounded suspicious. I kept second-guessing myself while the food processor ran, convinced the mixture was too wet to ever crisp up. Thirty minutes later I pulled them out and they had this pale golden color, and I could already hear the crunch when I tapped one with my finger. The cayenne is subtle but it’s there, and the parmesan gets this nutty, almost browned edge on a few of them that I liked best. I ate about six while they were still warm and rationed the rest. First batch of anything keto that didn’t feel like settling.
