McDonald's Mayonnaise Packet Complete Information
A McDonald's Mayonnaise Packet costs $0.30 and carries 90 calories, which makes it by some distance the heaviest packet on the sauce card and the one people are most likely to underestimate.
Ninety calories in a condiment packet is more than a third of a 250 calorie Hamburger, and it is roughly triple the 30 calorie Spicy Buffalo dip cup despite being a fraction of the size. It is the same mayonnaise that goes on the $3.79 McChicken, which is why removing it from that sandwich takes about 90 calories off at no cost. For anyone counting, this is the single item on the McDonald's menu with the widest gap between how small it looks and what it carries. Pair it with a McChicken if you want more of it, or leave it off that sandwich if you do not.
