Cheddar’s mac & cheese is supposed to be vegetarian, although certain stores may bend the rules for one reason or another. You see, the macaroni & cheese is supposed to be made with vegetable stock, which would make it vegetarian-friendly. But some Cheddar’s locations use chicken stock instead. For the best results, consider calling your local Cheddar’s eatery ahead of time and asking which type of stock they use for mac & cheese before visiting them for a meal. That way, they’ll be able to warn you if they don’t make vegetarian-friendly mac & cheese.
