Keto Big Mac Crunchwrap

I’ve made this recipe more times than I can count, and the tostada shell in the middle is what separates it from every other burger wrap out there. Without it, you’re eating a quesadilla with ground beef filling. With it, you get that signature crunch between two beef patties that makes the whole thing taste like actual fast food. That texture contrast is the reason I keep coming back to this one.
This is my keto take on the Taco Bell Crunchwrap, loaded with all the classic Big Mac components. I use the same crunchwrap technique but swap seasoned beef for thin smash-style patties and layer in American cheese, special sauce, dill pickles, onion, and lettuce. The homemade tostada shell in the center adds that critical snap, and it only takes about 5 minutes to fry.
I tested this with store-bought cheese crisps instead of the homemade tostada, and it works in a pinch. But the real shell is better. A reader named Derek tried the same shortcut and came to the same conclusion. The almond flour tostada has a corn-style crunch against the soft tortilla that a cheese crisp can’t replicate. Jasmine’s husband said this was better than McDonald’s, and when I asked what made it, she pointed straight to the tostada.
I shape the patties thin so they cook fast and fit inside the tortilla. Two minutes on the first side, one on the second, and they’re done. Thick patties make the wrap too tall to fold and the center stays undercooked. Thin is the move here.
Each serving comes in at 8.9g net carbs with two patties, two slices of cheese, and all the fixings. If you want other keto ground beef dinners in the rotation, I also make cheeseburger soup and tacos during the week. But this is the one my family requests on Friday nights.
One discovery I picked up from a reader named Ryan: mix a splash of pickle juice directly into the special sauce instead of just using minced pickles. It’s tangier and cuts through the beef fat in a way that straight vinegar doesn’t. I tried it and I’m not going back to the original ratio. The brine brings more depth than just acid, and the sauce tastes closer to the original because of it.
How to Make a Keto Big Mac Crunchwrap
Start by mixing the special sauce so it can chill while you prep everything else. I make the tostada dough next, press the shells thin, and fry them until they’re golden and rigid. While those cool, I form the beef into 8 thin patties and grill them hot and fast.
Assembly goes in layers: large tortilla, cheese, patty, sauce, onion, pickles, lettuce, then the tostada shell. Repeat the toppings with the second patty, place the small tortilla on top as a lid, and fold the edges of the large tortilla inward. Press down firmly with a spatula the second you flip it seam-side down. A reader named Corinne figured this out on her second batch, and I do the same thing now. The melted cheese locks the seam shut and keeps everything inside.
This is a solid keto dinner when you want something that feels like fast food. If you like this style, my quesarito uses a similar assembly method.

Step by Step Instructions
Step by Step Instructions
Make the special sauce
In a small bowl, combine mayonnaise, ketchup, vinegar, minced dill pickle or dill pickle relish, sugar free sweetener and minced onion. Add salt and pepper to taste. Set aside or refrigerate until ready to use.
- 1/2 cup mayonnaise
- 2 tablespoons ketchup (no-sugar added)
- 1 tablespoon vinegar (white or apple cider)
- 1 tablespoon minced dill pickle or dill pickle relish
- 1 teaspoon sugar free sweetener
- 1 teaspoon finely diced onion
Make the tostada dough
To a small bowl, whisk together almond flour, protein powder, xanthan gum and salt. Stir in hot water and mix until a dough ball forms. Divide the dough into 4 even balls.
- 1/2 cup + 2 1/2 tablespoons almond flour
- 1 tablespoon unflavored zero carb protein powder
- 1/2 tablespoon xanthan gum
- 1/4 teaspoon salt
- 3 tablespoons water
Flatten and fry tostada shells
Using a tortilla press or a rolling pin, place a ball of dough in between two parchment circles and press or roll out to a thin circle. To a medium skillet, add enough avocado oil to fill the bottom of the skillet 1 cm from the bottom (just enough so the tortilla will submerge while frying) and heat over medium heat. Once oil is hot, peel off the parchment paper from each side and place in the oil. Press down tortilla with a spatula and let fry for 2-3 minutes or until golden brown. Flip over and fry the other side for 1-3 minutes until golden brown, hardened or almost hardened. Remove from oil and place on a paper towel lined plate to dry. Repeat with remaining shells.
- avocado oil
Grill burgers
Divide the ground beef into 8 equal sized balls. Using a tortilla press or a rolling pin, place a ball of ground beef in between two parchment circles and press or roll out to a thin circle. Cook each thin patty in a non-stick skillet over medium-high heat. Season one side with salt. Grill on the first side for about 1-2 minutes or until the underside is lightly charred. Flip and cook the other side for 1 minute. Remove and place on a paper towel lined plate. Repeat with remaining ground beef.
- 1 lb ground beef
Assemble the first layer
Add 1 slice of American cheese to a large tortilla. Followed by 1 beef patty. Spread 1 teaspoon of special sauce on top of the patty. Sprinkle on 1/2 teaspoon minced onions and 1 teaspoon of minced pickles or relish. Top with 1 tablespoon shredded lettuce.
Assemble second layer
Add the hard tostada shell on top of the lettuce, followed by another burger patty. Spread 1 teaspoon of special sauce on top of the patty. Sprinkle on 1/2 teaspoon minced onions, 1 teaspoon of minced pickles or relish, and 1 tablespoon shredded lettuce. Top with 1 slice of American cheese.
Fold crunchwrap
Place the small soft tortilla on top of the ingredients and fold the ends of the large tortilla to meet the small tortilla.
Seal and make crunchy
Spray a medium skillet with cooking spray and heat over medium heat. Place the crunch wrap in the skillet seam side down, press and hold down with your hand in order to keep the contents from coming out and let cook for 2-3 minutes or until it starts to brown and the seam is set (meaning your crunch wrap won’t fall open). Flip and fry the crunchwrap on the other side for 2-3 minutes or until golden brown. Cut in half and serve.

Can I use a store-bought tortilla instead of making the tostada shell?
I've done this when I'm short on time and it works fine. Grab a small tortilla (about 4 inches) from the store. Mission sells zero net carb ones that are the right size. Fry it flat in oil until it hardens into a tostada. The homemade shell tastes better though. It has a slightly nutty flavor from the almond flour that the store-bought version doesn't have. If you're in a real rush, a cheese crisp works too, but you lose that corn-style crunch.
I don't have a tortilla press. How can I flatten my tortillas and burgers?
I use a rolling pin when my tortilla press isn't handy. Sandwich the dough between two sheets of parchment paper and roll it out thin, about the thickness of a pencil. Same trick works for the burger patties. I press each one between parchment circles and roll until it's uniformly thin. That way everything cooks evenly and the wrap folds flat without a thick lump in the center.
How can I make this lower carb?
If you're tracking macros on keto, most of the carbs come from the large tortilla and the American cheese. I've swapped in cheddar instead of American and that drops each wrap by about 2 carbs. For the tortilla, look for the lowest carb option you can find. The La Banderita I use is 5g net carbs per tortilla. You could also try cheese taco shells as the outer wrap to cut carbs further, though the fold won't be as clean.
Can I make these in the air fryer instead of a skillet?
I've done this plenty of times. After assembling, place it seam side down in the air fryer basket at 375 degrees for 4-5 minutes. You don't need to flip it. The circulating heat crisps the top without the flip. My air fryer is also my go-to for reheating leftover wraps (3-4 minutes at 375, straight from the fridge). If you like air-frying fast food remakes, my Doritos Locos tacos work great in there too.
Can I add pickle juice directly to the special sauce?
A reader named Ryan started doing this after his third batch and I tried it right after reading his comment. Instead of just minced pickles, add a splash of pickle brine directly into the sauce. It's tangier and cuts through the beef fat better than the vinegar alone. The brine has more complexity to it than straight acid. I'm not going back to my original ratio. Start with about a teaspoon and adjust from there.
Why does my crunchwrap fall apart when I flip it?
This happened to me on my first attempt too. The fix is pressing down firmly with a spatula the second you flip it seam-side down in the skillet. Hold it there for about 30 seconds while the cheese starts melting into the seam. That's what locks everything in place. A reader named Corinne figured this out on her second batch and it's exactly what I do now. Don't be gentle with it. The harder you press while the cheese is still melty, the tighter the seal.
I've made probably every keto Big Mac version floating around online, and most of them nail the flavor but lose the texture somewhere. This one actually gets both right. The homemade tostada shell in the middle is what does it, that crunch holds up even after you fold everything together. Not soggy at the bottom, not falling apart. This is the one I'm keeping.
Had real doubts about the tostada shell actually holding everything together, but the xanthan gum dough fries up with this satisfying snap I did not expect. Tried three other keto crunchwrap recipes before landing here. None of them got the structural layer right.
Served these at a dinner party and one of my friends who eats everything (not keto, not tracking anything) pulled me aside to ask how I made the crunchy layer inside. Freaking vindication. Four stars only because the assembly is genuinely time-consuming when you're making four servings.
Non-keto friend asking about the tostada layer is the best part of making these. For four at once I stage it: shells fried first, all the patties done together, then wrap and seal in a batch. Way less back and forth.
Third time making these and this week I tried mixing a splash of pickle juice directly into the special sauce instead of just the minced pickle. It's tangier and cuts through the beef in a way that works better for me. Not going back to the original ratio.
The sauce already has vinegar in it, but brine's got more to it than straight acid. Stealing this.
Fold game is everything. Press down hard with the spatula when you seal it or it pops open. Second batch came out perfect.
Yes! That's exactly it. I do the same thing - really press it down while it's still warm and the cheese is melty. Makes all the difference.
Skipped making the tostada shells and used a cheese crisp instead. Still really good but I bet the real shells are better.
The tostada is where the texture contrast comes from. Cheese crisp works in a pinch but yeah, that corn crunch in the middle against the soft tortilla is the whole point.
My husband literally said "this is better than McDonald's." The tostada shell in the middle is what makes it.
That's high praise! The tostada is where the texture contrast comes from - without it you're just eating a quesadilla with burger filling.
