I combined my keto hard taco shell with my Doritos chip seasoning to build the crunchiest Taco Bell copycat at only 3 g net carbs per shell.
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.
The seasoning ratio took me the most testing to nail. 3 tablespoons of cheddar cheese powder to 1.5 teaspoons of chili powder and 3/4 teaspoon of smoked paprika hits that familiar nacho cheese punch without tipping into overwhelming. You can mix it all into the dough or dust it on after frying if you want that orange-finger Doritos experience. I usually mix it in.
I press a full batch of 8 shells most Sundays and they hold their crunch for about 3 days in an airtight container at room temp. My family goes through them fast enough that storage is rarely the issue, but you can freeze them for up to a month (layer parchment paper between shells so they don’t stick). I also fry these flat sometimes for a quick tostada-style base that works great loaded up with toppings. If you’re into the Taco Bell copycat thing, my keto quesarito and keto crunchwrap are worth adding to your rotation.

Step by Step Instructions
Step by Step Instructions
Mix dry ingredients
In a medium bowl, whisk together almond flour, protein powder, xanthan gum, salt, cheddar cheese powder, chili powder and smoked paprika.
Finish tortilla dough
Pour in hot water and mix with a fork until combined.
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.
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.

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.
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.
Made a double batch of shells on Sunday and they've held up through the whole week. The key I figured out is to let them dry way longer than you think (I went almost 45 minutes instead of just until they hold shape), and the crunch stays even after a few days in a container. Been filling them fresh each night and this might be the best taco meal prep I've landed on.
45 minutes is closer to right. Xanthan gum needs that extra time to set fully, and that's what keeps the crunch from going soft days later. Weekly batch, fresh fillings every night - I'd eat tacos every night too.
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.
Hot oil, not medium-hot. That's the one I tell people about most. The Dorito crunch doesn't happen otherwise.
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.
Ha, the shells go fast in my house too. That seasoning ratio took the most testing to nail.
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.
3 days in an airtight container at room temp, or freeze them for up to a month. Layer parchment between the shells so they don't stick together.
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.
That's really strange. I have made these several times and they never puff up. What brand of protein powder did you use?
Hi! I’m wondering if one could fry these flat for tostados or would they be too flexible?
Yes, you can fry them flat like a tostada!
