Yes, this dish is vegetarian-friendly.

If you’re vegetarian, ensure to choose Parmesan cheese that is labeled as vegetarian.

Some Parmesan cheeses contain animal rennet, which is not vegetarian.

We recommend usingYukon Gold potatoes, which are thin-skinned potatoes with yellow flesh and buttery flavor.

They have a creamy yet firm texture that falls between starchy russets and waxy red potatoes.

Theyll crisp up well and hold their shape after baking.

The potato galette also pairs well with asimple green saladfor a delicious weeknight meal.
