This hearty soup features tender strips of beef, sautéed bell peppers, onions, and mushrooms swimming in a decadent, velvety broth that captures the essence of a perfect cheesesteak.

To deliver that signature experience, the broth is infused with a generous amount of melted provolone and cheddar cheeses, creating a creamy texture that pairs perfectly with the savory steak and vegetables. Served alongside toasted hoagie slices or crusty bread for dipping, it is an ideal meal for chilly evenings when you want something substantial and incredibly satisfying.
