Start by preheating your oven to 375°F (190°C). Prepare a 9×13-inch casserole dish with a light greasing or a quick spray of non-stick cooking spray.
Carefully unroll the crescent dough sheet and fit it into the bottom and up the sides of the dish, fixing any tears to create a seamless base.
In a small mixing bowl, blend the melted butter with garlic powder, mustard, and onion powder (if using), achieving a smooth mixture.
Spread this buttery blend evenly across the crescent dough, ensuring full coverage.
Scatter the diced ham evenly over the dough layer, followed by a generous sprinkle of shredded cheese. Season the assembly with salt and pepper according to your preference.
Bake in the oven for 15 to 17 minutes, or until you notice the edges turning a rich golden brown and the cheese bubbling with melted perfection.
Once done, allow the casserole to cool briefly before slicing into squares or rectangles. If desired, add a sprinkle of chopped fresh parsley for a dash of color and freshness.
Serve this Ham and Cheese Crescent Rolls Casserole warm to capture its full comfort and flavor. It’s not just a dish; it’s an experience of warmth, comfort, and communal joy, making it a cherished recipe for any family table.
