Review: McDonald's - Signature Crafted Mushroom & Swiss Burger

McDonald's Signature Crafted Mushroom & Swiss Burger features a quarter pound fresh-beef patty, seasoned mushrooms, creamy bistro aioli, Swiss cheese, and crispy onion strings on a toasted artisan roll.

I paid $5.39 for one.

There were some good-sized sliced mushrooms in my burger. They were tender and added a nice flavor. That flavor was enhanced by the bistro aioli, which offered a creamy, savory base tinged with mushroom and garlic notes.

The onion strings are the same as can be found in the Bacon Smokehouse Signature Crafted sandwiches and layer on some season onion-y crunch. They're actually pretty good out of the burger as well (why are seasoned onion strings/rings not a thing?).

The Swiss cheese got mostly lost in the mix given it's mild quality but has an enjoyable taste if you nibble at the edges (or pinch off a piece).

The beef patty was moist with a coarse grind that comes apart more easily when compared to McDonald's frozen patties (the ones in the regular hamburger and its variants as well as the Big Mac). The bun was soft but not too soft with a dense crumb.

Taken altogether, McDonald's Signature Crafted Mushroom & Swiss Burger turned out really well. The crispy onions in particular keep it interesting while the mushroom and Swiss are solid.
