Frequently Asked Questions
While many recipes will call for French dressing, or even just using Thousand Island dressing, Big Mac sauce is actually neither of those. It is a blend of mayo, ketchup, mustard, sweet pickle relish, vinegar, and other spices and seasonings. For this recipe I use my own homemade burger sauce recipe.
You can pile this casserole on top of shredded lettuce to make a delicious Big Mac salad. Alternatively, you can try my Bacon Cheeseburger Salad Recipe.

Easy to make, and we all loved it. You need to make two times or even three times the amount of sauce because you put it in the meat and then you pour it on top and then if you put it on lettuce, you need to put it on the lettuce and it’s delicious!

My family loves this recipe and I am regularly asked to make it. Even when we aren't doing keto we still make this recipe. We've tried several of Kendra's recipes and all of them have been delicous!
Karen says
This is the BEST recipe. I’ve made this many times. Just wondering why you changed the recipe from using your delicious Russian dressing to the “burger sauce”
I’m sure the newer version is yummy too. But just curious.

Amber Weber says
Excellent! I always really enjoy Kendra’s recipes and am grateful for all the work she puts into them.
This was no exception. I did not have fresh herbs or spicy brown mustard for the Russian dressing, so I used dried herbs and Dijon mustard. I look forward to making this again with all the correct ingredients, but in the meantime, I will enjoy this for lunch for the next 6 days!
