Crunchy keto Doritos Locos tacos, my hard taco shell with the nacho cheese seasoning worked into the dough, at 3.2g net carbs per shell. I whisk cheddar cheese powder, chili powder, and smoked paprika into the dry mix, press each ball flat, fry, and I let the shells dry upside down, where they keep hardening into that snap.
I've been trying to crack the Taco Bell Doritos Locos taco in my own kitchen for a while now, and this is the version that finally got there. The original is one of those fast food items that feels impossible to recreate at home, let alone make low carb. But I took my keto hard taco shell recipe and worked in the seasoning from my keto Doritos chips to get that cheesy, slightly spicy crunch you remember from the drive-through window.
The shell is built on almond flour, unflavored protein powder, and xanthan gum. Those three give you a dough that presses thin, holds together in hot oil, and crisps up so hard it cracks when you bite in. Most copycat recipes online just wrap a cheese slice around a regular shell. I wanted the seasoning worked into the dough itself, and that's what gives you flavor all the way through, not just on the outside.
Here's the thing I tell everyone first: the oil needs to be hot, not medium-hot. I spent too many early batches frying at medium heat and getting shells that were chewy instead of crunchy. When I let the oil get properly hot (around 350-360'F), the xanthan gum sets fast and the outside turns golden and rigid in about a minute per side. That's the difference between a floppy tortilla and a shell that sounds like a real Dorito when you snap it.
If you're into the Taco Bell copycat thing, my keto quesarito and keto crunchwrap are worth adding to your rotation.
I use just three ingredients to get that iconic Doritos nacho cheese flavor at home:
Cheddar cheese powder
Chili powder
Smoked paprika
The ratio matters more than the ingredients themselves. I tested probably a dozen combinations before landing on this one, and the smoked paprika is what ties it together. Without it, you just get cheese. With too much, you lose the chili kick.
You can mix the seasoning directly into the tortilla dough or dust it on after frying. I prefer mixing it in because the flavor bakes into every bite, but dusting gives you that classic orange-coated-fingers thing. If you want to try a different flavor profile, I also have a keto Cool Ranch Doritos recipe that could work as a starting point for a Cool Ranch shell.
Low carb taco filling ideas
Once your shells are ready, load them up. Here are my go-to fillings:
Seasoned ground beef with shredded lettuce, diced tomatoes, and sour cream (the classic Taco Bell build)
Shredded chicken with guacamole and a squeeze of lime
Shredded cheese melted right into the warm shell
Minced jalapenos and black olives for heat
Green onions or red onions for crunch
Hot sauce or nacho cheese drizzle
I personally load mine with ground beef and way too much shredded cheese, then top with sour cream. For a full taco night spread, my taco salad works great on the side. And if you want a different shell altogether, my cheese taco shells skip the dough entirely and use melted cheese as the base.
How I store leftover shells
There are two ways to store these depending on where you are in the process.
Storing unfried tortillas
If I’ve pressed the dough but haven’t fried yet, I stack the tortillas between sheets of parchment paper, slide them into a freezer bag, and keep them in the fridge for up to 5 days. They also freeze well for 1-2 months. I pull them out and fry straight from the fridge with no thawing.
Storing fried taco shells
Fried shells stay crispy for about 3 days at room temperature in an airtight container. After that they start going stale. I’ve found that letting them dry upside down for longer than you’d think (a full 30-45 minutes, not just until they hold shape) helps them stay crunchy for the full 3 days. Reader Natalie mentioned the same thing in the comments and she’s right. For freezing, layer parchment between shells and they’ll keep for about a month. Pop them in a 350’F oven for a few minutes to restore the snap.
In a medium bowl, whisk together almond flour, protein powder, xanthan gum, salt, cheddar cheese powder, chili powder and smoked paprika.
2
Finish tortilla dough
Pour in hot water and mix with a fork until combined.
3
Press into tortillas
Divide the dough into 8 balls (about 2 inches in diameter). Place each ball in between two circles of parchment paper and use a tortilla press or rolling pin to flatten into a circle about 6 inches wide. Leave each tortilla in between the parchment paper.
4
Make hard shells
Pour 1/2 inch of avocado oil into a skillet and heat oil over medium heat. Add a tortilla and submerge it in the hot oil. Let it cook for a minute, then use two spatulas to fold it over into a taco shape. Let it fry for about a minute or until just about hardened. Flip and fry the other side for another minute.
5
Let dry
Remove and let dry upside down on a paper towel lined tray. This will help hold the taco open as it dries. The taco shell will continue to harden as it dries.

Frequently Asked Questions
What oil temperature should I use for the crispiest shells?
I fry mine at around 350-360'F and that's where the real crunch happens. When I was frying at just medium heat, the shells came out more chewy than crispy because the xanthan gum needs that burst of heat to set quickly. I use a thermometer now and it changed everything about the texture. If you don't have one, drop a tiny piece of dough in and it should sizzle immediately. Multiple readers have confirmed the same thing in the comments.
Which protein powder brand works best for these taco shells?
I use an unflavored whey isolate and it works perfectly every time. I've had readers tell me their shells puffed up during frying, and every time I've dug into it, the protein powder was the culprit. Stay away from plant-based blends and anything with added fiber or thickeners because those trap air and cause puffing. A basic unflavored whey isolate or egg white protein powder is what you want.
Can I bake or air fry these instead of deep frying?
I've tested the air fryer route and it works, but the texture is different. You won't get that deep-fried crunch that makes these taste like actual Doritos shells. If you want to try it, brush both sides with avocado oil and air fry at 375'F for about 4-5 minutes, flipping halfway. They come out more like a firm tortilla chip than a true hard shell. For the closest Taco Bell experience, I still recommend stovetop frying.
Can I fry these flat as tostadas instead of folding?
Yes, and I do this all the time now. Same dough, same oil temp, just skip the fold and let the whole round fry flat for about a minute per side. They come out perfectly rigid and crispy. I load mine up with seasoned beef, lettuce, sour cream, and hot sauce for a quick dinner. My low carb tostadas recipe is another option if you want a different dough base.
Can I make a Cool Ranch or Fiery Doritos version?
I've played around with both. For Cool Ranch, I swap the cheddar cheese powder for a ranch seasoning base (dried dill, onion powder, garlic powder, and buttermilk powder) and it comes out tangy instead of cheesy. My kids actually prefer that version. For a Fiery take, I add about 1/4 teaspoon of cayenne pepper and an extra pinch of chili powder to the regular nacho cheese seasoning. Start with less cayenne than you think because it intensifies during frying.
What can I use instead of cheddar cheese powder?
I've tried finely grated real cheddar and it works in a pinch, but the texture changes. Real cheese adds moisture, so the dough gets stickier and you might need a bit more almond flour to compensate. Cheddar cheese powder gives the cleanest result because it adds flavor without extra liquid. For a dairy-free option, I've had good luck with nutritional yeast (about 2 tablespoons) plus an extra pinch of smoked paprika to round out the flavor.
How many calories and net carbs are in these compared to Taco Bell?
Taco Bell's original nacho cheese version runs about 170 calories and 13g of carbs per shell. Mine lands at 3g net carbs, and that gap is the whole reason I built these. You still get the loud nacho cheese crunch you want, just without the drive-through carb hit. Taco Bell's shell: 13g carbs. This one: 3g net carbs. The difference comes down to swapping the fried corn shell for my almond flour dough.
Fatima, it’ll work in a pinch but I use straight cheddar powder, not the mix packet. The mac and cheese version has extra salt and whey in it so the flavor isn’t as clean.
First batch success usually means the oil temp was where it needed to be. Try making them flat as tostadas next time, same dough, just skip the fold and fry them flat. My family fights over those.
Oil temp is the whole thing with these. The xanthan gum needs that heat shock to set fast, otherwise the shell slumps before the fold holds. I test with a drop of water, if it sizzles right away the oil’s ready.
This is my fourth or fifth batch of these now and I finally nailed the frying time. Going a little longer than I first thought, like 30 extra seconds per side, and the shells come out with a crunch that actually holds when you fill them. The cheddar cheese powder in the seasoning is what gets me (it’s surprisingly close to the real thing). These are in the weekend rotation for sure.
Yeah, that extra 30 seconds is right. The xanthan gum needs the full heat or it just stays soft inside. The cheese powder ratio took me several rounds to nail, it has to read as Dorito, not just ‘cheesy taco.’
No tortilla press, so I flattened the dough between parchment with the bottom of a cast iron skillet. Kept expecting them to crack in the oil, but they held up and actually crisped. The chili powder and cheese smell while frying basically got me. Already planning a double batch.
Cast iron works. More even pressure than my press some days. That chili powder and cheese powder hitting the hot avocado oil is the part I always slow down for.
Shells came out great, that cheddar powder seasoning is spot on. The frying step takes a little trial and error to nail the oil temp, mine were a bit pale on the first batch. Once you dial it in though, they hold their shape way better than I expected.
I was skeptical that almond flour shells could fry up with a real crunch. Not “close enough” crunch, but the kind where you can hear it. Made them Sunday and they delivered. The cheddar seasoning hits that Doritos note surprisingly well, and the shells held together with a full taco load inside. Genuinely did not see that coming.
Switched to cast iron for frying and the shells came out way crispier than my first two attempts in a regular skillet. The heat retention does something different to the avocado oil, you get this almost uniform crunch instead of soft spots in the middle. Flavor is already locked in with the chili powder and cheddar powder combo, so the texture upgrade just made the whole thing click. Giving it 4 stars because the xanthan gum ratio took me a couple rounds to get right, but once I had it dialed, these held up through a full taco build without cracking.
Cast iron for these didn’t occur to me but it makes sense. The temp drop when the shells hit the oil is always the thing, and cast iron just holds steady. Trying this.
Made these so many times I’ve lost count, but something clicked around batch seven or eight. The oil temperature is everything. I was running it at medium and they were fine, but when I let it get actually hot before dropping the shell in, I started getting that crunch that sounds like a real Dorito when you bite in (I mean exactly like it). The seasoning builds as you eat and I found myself going back for a third shell before I even filled it. Now I press and fry a full batch on Sundays and they hold up crispy for three days. Spring is basically just one long run of taco nights.
My daughter grabbed a shell off the tray before I even started assembling and ate it plain. Said it tasted like actual Doritos. That seasoning is spot-on.
First time trying a recipe like this and honestly wasn’t sure if I could pull it off. The shells came out so crispy though! One question, how long do these stay good if I make extra? Want to have them on hand for quick dinners.
These sadly didn’t turn out at all. I used the ingredients it called for in correct amounts and flattened each tortilla to 6”. They were whisper thin until you started cooking them, then they started puffing up and no way you could cook one 2 minutes, even with my heat on 2 of 10! They were more like a cheesy flour tortilla that was fried. Maybe a hair crisp at edges. No idea how you got yours to look like that after cooking. Flavor was good though, I don’t think it’s worth the trouble. So I’m still on the lookout for something to give me that fried corn tortilla crunch.
