How to make caramelized onions?

Caramelized onions are one of the most delicious yet underrated foods ever. Yellow onion slices are cooked in fat, usually butter, over medium-low heat for a prolonged period of time. The goal is to get the onions soft and golden without burning them. They require patience and lots of stirring. The result is buttery, sweet, and caramel-colored onions that taste amazing on their own.

Can you swap the mozzarella for another type of cheese?

Absolutely! Try substituting it for other melty cheeses like provolone, gouda, cheddar, or gruyere for a classic combo. This dish would also be tasty with stronger cheese types like parmesan, aged gouda, or asiago.
