You may have noticed that we have a thing for Big Macs around here.

Honestly, sometimes I still hit up the drive-thru and get a Big Mac…I just bring it home and dump it into a low carb tortilla.

It’s a quick and dirty way to enjoy a Big Mac, but I’ve come up with a few healthier options that skip the drive-thru altogether, like this Big Mac Chaffle, Big Mac Salad, and now this Big Mac Casserole!

When you’re craving a burger, this casserole will do the trick!

Start by browning up some ground beef along with some garlic.

Stir in some cream cheese, sugar free ketchup, mustard, Worcestershire sauce, and seasoned salt. This all gives the beef amazing flavor!

Sugar Free Ketchup: Believe it or not, regular ketchup is LOADED with sugar. We use and love Heinz No Sugar Added – tastes just like the kind I grew up with. ๐Ÿ˜‰ You can use whatever brand you prefer, but we love Heinz!

Spread the beef into an 8×8 baking dish and then whisk together some eggs, cream, and a dash of hot sauce.

Pour the eggs over the beef and top it all off with some shredded cheddar.

This will bake for about 30 minutes.

Big Mac Sauce:

While the casserole is baking, whip up that keto big mac sauce.

Just stir together mayo, ketchup, dill relish, mustard, vinegar, onion powder, and paprika until smooth and creamy.

We use this sauce on burgers all the time – so good!

Serving:

Once your Big Mac casserole is cooked through, slice and serve.

We like to top our casserole with shredded lettuce, minced onion, pickles, sesame seeds, and a hefty drizzle of the big mac sauce.

It tastes just like the Big Mac you’d get from McDonalds, but better, fresher, and healthier!

    Hi, your instructions say “Pour the egg mixture over the beef and bacon”. I do not see any mention of Bacon as an ingredient. Sounds good though!
