The crunchiest keto pasta chips start as low-carb pasta in my air fryer — tossed in parmesan and Italian seasoning, 3.2g net carbs and 10.9g protein. They're what I reach for on movie night instead of popcorn.
I saw pasta chips all over TikTok and thought, there's no way this works with low-carb pasta. Regular pasta goes crispy in the air fryer because of the starch, and most keto noodles barely hold together when you boil them. But I had to try. I grabbed a bag of lupin flour pasta in a ziti shape, tossed the cooked noodles in olive oil and parmesan, and air fried them at 400 degrees. Six minutes later, I had a bowl of something that actually crunched.
The hardest part was finding a noodle that would hold up. I tried three different brands before landing on the lupin flour ziti. Most crumbled apart in the air fryer or came out chewy instead of crispy. The lupin flour version stayed intact and crisped up with real crunch, not just a dry texture. You can also try these wheat-based keto noodles if you can't find the lupin ones.
The seasoning is straightforward: olive oil, grated parmesan, garlic powder, Italian seasoning, salt and pepper. I coat every single noodle before they go into the air fryer because any bare spots won't crisp up the same way. The oil is what turns the pasta surface golden and crunchy instead of just dried out.
One thing I picked up after a few batches: shake the basket halfway through cooking. The noodles sitting on the bottom get more direct heat, so giving them a shake at the 3-minute mark spreads the crispiness evenly. I also undercook the pasta slightly before air frying (about a minute less than the package directions). If you go full al dente, the pieces tend to crumble once they dry out. Pull them a little early and they keep their shape while still getting that crunch you want.
I keep these around as a snack the same way I keep keto tortilla chips or avocado chips stocked in my pantry. They're great on their own with just the parmesan seasoning, and the tube shape of the ziti actually scoops up dips better than any flat chip I've tried. I started making a double batch on Sundays so we have them ready for the week.
Each serving has roughly 3g net carbs and 12g protein, which makes this one of the better snack options on keto for actually keeping you full. I've served these alongside keto nachos at game day and nobody realized the pasta was low carb.
Best pasta shapes for air fryer chips
You want a shape you can pick up with your fingers, so spaghetti and fettuccine are out. When I’m shopping for low-carb pasta, I look for these shapes:
Ziti or rigatoni: my top pick. The tube shape gets crispy on the outside and slightly hollow inside, which gives you that satisfying crunch. They also scoop dip better than flat shapes.
Penne: works well, similar tube shape but slightly smaller. Crisps up evenly.
Macaroni: the curves crisp nicely, though they’re smaller and harder to dip.
Dips to serve alongside
These are great on their own, but I almost always set out a dip when I make a batch. Here are my go-to pairings:
I keep leftovers in an airtight container at room temperature. They stay crunchy for 3-4 days. Don’t refrigerate them. The moisture softens the coating and you lose that crunch. For longer storage, I freeze them and reheat in the air fryer for about 2 minutes (they crisp right back up).
Cook pasta in boiling water according to package directions. Cook until al dente. Drain and add to a medium bowl.

Frequently Asked Questions
Can I freeze pasta chips?
I freeze these all the time when I make a big batch. Lay them in a single layer on a baking sheet, freeze until solid (about an hour), then transfer to a freezer bag. They keep for up to 2 months. When I'm ready to eat them, I put them back in the air fryer at 400 degrees for about 2 minutes and they crisp right back up.
How do I make them extra crispy?
I've made enough batches to know what works. First, undercook the pasta slightly (about a minute less than the package says). Fully cooked noodles crumble as they dry out. Second, make sure every noodle is coated in oil before air frying. Bare spots dry out instead of crisping. Third, shake the basket at the 3-minute mark so the bottom pieces rotate to the top for even cooking.
Are these gluten-free?
The lupin flour pasta I use is gluten-free, so yes. If you go with the wheat-based keto noodle option, those do contain gluten. I've linked both in the recipe so you can pick what works for your situation.
What flavor variations can I make?
I've tried a few beyond the Italian seasoning version. My favorite is a salt and vinegar batch: I toss the cooked noodles in a splash of white vinegar before adding the oil and seasoning, then air fry as usual. I've also done a spicy version with red pepper flakes and a pinch of cayenne. Smoked paprika is another good one if you want something savory without the heat.
How many net carbs per serving?
With the lupin flour pasta I use, each serving comes out to roughly 3g net carbs and 12g protein. That's what makes these one of my favorite keto snacks. The protein actually keeps me full, which is more than I can say for regular chips.
Can I bake these in the oven?
I've done it when my air fryer was already in use. Spread the seasoned noodles on a parchment-lined baking sheet in a single layer and bake at 400 degrees for 8-10 minutes, flipping halfway through. They come out a little less evenly crisped than the air fryer version, but they still work.
What brand of low-carb pasta do you use?
I use a lupin flour pasta in a ziti shape (it's linked in the recipe). I tested about three different brands before settling on this one because most others either crumbled in the air fryer or came out chewy instead of crispy. If you can't find the lupin flour version, the wheat-based keto noodles I linked also work.
That skepticism is real, Camila. I made the first test batch expecting soggy, sad noodles (regular pasta absorbs oil and goes limp, so I figured these would too). Turns out the parmesan coating setting in the air fryer’s heat before the noodles have time to get soft, so you get this thin, crackly shell around each piece instead. Probably fifteen batches since, and the crunch holds.
I run mine at 380 and start checking at 8 minutes. Air fryers vary enough that you want to watch the first batch – you’re looking for golden edges and the parmesan to set, not just a timer.
Added smoked paprika alongside the Italian seasoning and the parmesan got this deeper, almost nutty coating in the air fryer. Still figuring out the right batch size since they don’t all crisp up evenly, but the flavor’s there.
Smoked paprika works so well with the parmesan. The uneven crisp is almost always an overcrowding thing. Single layer, no overlap, and shake the basket halfway through. That usually fixes it.
My son watched me put pasta in the air fryer with visible skepticism and then quietly grabbed a second handful without a word. That was his entire review.
Tried this with cavatappi instead of a flat pasta and the corkscrew shape holds the parmesan coating in a way that every piece crisps up instead of the occasional flat one going soft in the middle. Pull them at 10-11 minutes if you want some chew in the center, full time if you like them snappy. Four stars because I genuinely cannot stop eating them, which is a me problem.
Every other keto pasta chip recipe I’ve tried ends up chewy instead of crispy and I could never figure out why until this one. The parmesan coating is it.
Not sure low-carb pasta would get crispy enough to be worth it, but air fried a batch anyway. The parmesan bakes onto each piece and you get this crunch that feels nothing like pasta. Stood over the counter eating them before I even sat down. Making these every movie night.
Standing over the counter is basically a required step. I started making a double batch on movie nights because the first one disappears before I even set up the air fryer for round two.
Do you need to let the pasta dry a bit after boiling before tossing it with the olive oil and parmesan, or does it go straight in? Worried the moisture will stop it from crisping.
Shake them well in the colander and go straight in. I don’t pat them dry or anything, just let the steam off for about 30 seconds, then toss with the oil while they’re still warm. The warmth actually helps the parmesan stick.
