What in the actual fuck is Tuscan about this chicken?

Warm regards from the currently chilly Pisa shoreline.

You often see dishes with cream and spinach described as Florentine, aka in the style of Florence, which is in Tuscany…

Apart from that tenuous connection, I have no idea. Why not just call it what it is instead of trying to brand it: seared chicken breast with spinach-tomato cream sauce…???

Because that’s an incredibly clunky name. I get that it can be frustrating, but we often call thing names that don’t really make sense, and it seems like the name Tuscan chicken already has a lot of staying power for this dish. French fries are not from France etc etc
Not a clue, it’s just what it’s called. Cheers!

In the US, Tuscan has come to refer to a certain flavor palette loosely associated with a couple dishes made at the Olive Garden, a chain restaurant that makes Italian American inspired food. There's a specific soup they make that looks and likely tastes like this.

It's no more Tuscan than any Italian American food, much less corporate chain food.

Probably still tastes great though.

Ah, yes! I figured it must have come from somewhere, but American chain restaurant are a quaint mystery to me.
Btw, if anyone is actually interested, the closest thing to a “Zuppa Toscana” is the Ribollita. It’s a essentially a bread soup made with mostly beans and cabbage.
I can’t even call them sand people anymore? Darn political correctness ruining everything.
