A comforting casserole that transforms classic Philly cheesesteak flavors into a cozy, shareable meal with a crispy provolone cheese crust.
If cheese browns too fast, tent casserole with foil halfway through baking. For extra crispiness, broil for 1-2 minutes at the end. Use room temperature milk for soaking bread. Let casserole rest after baking to firm up the cheese crust. For gluten-free, substitute bread with gluten-free cubes. For dairy-free, use vegan provolone-style cheese but crust may not crisp as well.
