McDonald's has been teasing this for years. The Chicken Big Mac has existed in various forms in the UK and Australia for a while, but it never made it to the US. Until now. On Monday, they launched it nationwide, and I was at my local McDonald's at 10:30 AM like an absolute dork. I ordered two — one to eat fresh, one to see how it held up after 20 minutes. I took notes. I took photos. I made my girlfriend take a bite and tell me what she thought. This is my completely unscientific but very thorough review.
What Actually Is a Chicken Big Mac?
It's not what you might think. It's not a Big Mac with chicken patties instead of beef. That would be too simple. Instead, McDonald's made two new chicken patties specifically for this sandwich. They're breaded, fried, and shaped like the classic Big Mac patties — same round shape, same size. Then they put them on a Big Mac bun with the same special sauce, lettuce, cheese, and pickles. But there's no middle bun. The traditional Big Mac has three buns and two beef patties. The Chicken Big Mac has two buns and two chicken patties, with the lettuce and sauce in between. It's a different architecture. I don't hate it.
The First Bite: Honest Reaction
I took a bite and immediately thought: 'This is way better than I expected.' The chicken patties are crispy on the outside, juicy on the inside. They're not dry like some of McDonald's previous chicken sandwiches. The flavor is mild — it's seasoned but not spicy, which makes sense because the special sauce is doing most of the heavy lifting. That tangy, creamy Big Mac sauce works surprisingly well with chicken. It's the same sauce you know and love, but on chicken, it tastes fresh and different. The lettuce adds crunch. The pickles add acidity. It all works together in a way that feels familiar but new.
How It Compares to the Original Big Mac
I'm a Big Mac fan. I eat one maybe once a month. The original is iconic for a reason — the beef, the sauce, the middle bun, it's a perfect fast food burger. The Chicken Big Mac is not better than the original. But it's not worse either. It's different. The chicken version is lighter. It doesn't sit as heavy in your stomach. The lack of a middle bun means you get more sauce-to-bun ratio, which some people might prefer. I missed the middle bun, honestly. That extra bread gives the Big Mac its signature architecture. The Chicken Big Mac feels more like a regular double-decker sandwich. Good, but missing that iconic structure.
The Calorie Count: Brace Yourself
If you're watching calories, look away. A Chicken Big Mac has about 590 calories. That's actually less than the original Big Mac (about 590 vs 550 — wait, they're almost the same?). I double-checked. The original Big Mac is 590 calories. The Chicken Big Mac is 600 calories. So basically identical. The chicken version has more fat (34g vs 29g) but also more protein (27g vs 24g). It's not a health food by any stretch. But nobody's eating a Big Mac for health. If you're going to indulge anyway, the Chicken Big Mac is a worthy alternative.
