What if I told you that you can have your favorite fast-food burger without all the carbs? These keto Big Macs are exactly that, right down to the ketofied Big Mac sauce. With as few as 6 net carbs per double burger, this keto burger more than checks all your fast-food craving boxes!
What Makes This Recipe So Good
- On keto and missing fast food? Don’t despair! This is the perfect keto copycat recipe for those classic Mickey D’s burgers – buns included! Each burger is double stacked just like the original and it’s full of onions, pickles, lettuce, cheese, and an incredible ketofied Big Mac sauce.
- This recipe makes a lot of burger. On the bright side, that means you could have leftovers for lunch the next day! If you’re planning on leftovers, I’d store everything separately so you can reheat the burger patty on its own. I don’t know about you but I’m not a fan of hot shredded lettuce. Leftover homemade Big Macs will keep up to 5 days – just refrigerate them in an airtight container!
- If you can’t have a Big Mac without the fries (I totally understand!), pair it with these keto rutabaga fries and use more keto Big Mac sauce (or keto ketchup) to dip them in.
Keto Hamburger Buns – You could do this with lettuce-wrapped burgers, but part of what makes a Big Mac so great is the layering of buns. For keto sesame seed buns, you can easily make your own using just a few ingredients, or you can find some from a number of brands. Just make sure to check the macros & ingredients list; some buns are better suited for a “dirty keto” approach. You could also make your own chaffles out of eggs and mozzarella, but that’s much less “bun”-like.
Ground Beef – There’s two ways to approach this one. You can either get ground beef and form your own burger patties, OR you can buy pre-formed patties (fresh or frozen). We use frozen quarter-pound patties a lot to save time and energy, but sometimes ya just gotta have them homemade.
Keto Big Mac Sauce – Don’t skip this! It’s what MAKES these keto Big Macs. It’s right there in the name! Our version of that classic sauce tastes just like the original but without all the added sugar. You are welcome.
- No granular Swerve? No problem. Any keto sweetener will work – just keep in mind that they don’t all substitute at a 1:1 ratio! Start with a very small amount and taste the sauce with each addition. You can always add more sweetener, but you can’ take it back out!
- For the crispest lettuce, shred it right before cooking your burgers, rather than a day or two in advance. If you shred it too far ahead of time, the lettuce will get soggy and lose that beautiful crunch.
- If you’re forming the burger patties yourself, incorporate the salt and pepper into the meat before flattening it into a patty. That way it’s seasoned throughout, rather than just on the top and bottom. If you’re using frozen burger patties, let them heat up in the pan a little before you season them; that way the salt and pepper actually sticks!

For the Keto Big Macs
- Liberally season burger patties on all sides with salt and pepper. Heat one large skillet over medium-high heat, then fry patties until cooked through, flipping as needed.
- While patties fry, butter insides of bun tops and bottoms. Heat second large skillet over medium-high heat. Once hot, add bun tops and bottoms buttered-side down and toast them, like you would a grilled cheese. Set buns aside until ready to assemble burgers.
- Once patties are cooked through, spread keto Big Mac sauce on buttered & toasted sides of all buns. Assemble burgers in the following order: bottom bun, sauce, onions, pickles, lettuce, burger patty, cheese, bottom bun, sauce, onions, pickles, lettuce, burger patty, cheese, top bun. Serve warm.

- Burger Patties: Form ground beef into 4 thin patties, or use 4 pre-made ¼-pound burger patties (we do this a lot to save time). If you’re forming the burger patties yourself, incorporate the salt and pepper into the meat before flattening it into a patty. That way it’s seasoned throughout, rather than just on the top and bottom. If you’re using frozen burger patties, let them heat up in the pan a little before you season them; that way the salt and pepper actually sticks!
- Keto Sesame Seed Buns: Make your own or use store-bought keto buns like these from Wholesome Provisions. The nutrition information shown was calculated using Wholesome Provisions’ buns. You could also use chaffles instead of buns. Want to save a bun? You need 4 bottom buns + 2 top buns total for your burgers. If you take 3 bottom buns and 3 top buns, and cut the domed “top” off one of the top buns, you now have 4 bottom buns and 2 top buns!
