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.

This is BY FAR one of the BEST low carb recipes I've come across. I've made it numerous times and can't praise it enough. Love the Russian dressing...I double it and use it for this recipe as well as a salad dressing. Thank you SO much for your labours in coming up with this recipe. Love it! (in case you couldn't tell)

My whole family loves this, we have made it several times!! I always use my own homemade mayo, and reduce the amount of dressing added in to beef by half...then use the leftovers as a dressing for the salad! Thanks for a great recipe!
