Add the beef (or thin-sliced steak) and cook until browned. Drain if needed.

Cook until they soften and get slightly caramelized around the edges.

Reduce heat and stir in cream cheese until melted and blended.
Pour in heavy cream and Worcestershire sauce.
Simmer 2–3 minutes until everything looks rich and cozy.

Transfer the mixture into a casserole dish.
Lay provolone slices over the top—cover it generously, like a cheesy blanket.
5. Bake
Bake at 375°F for 18–22 minutes, or until the cheese is melted, bubbly, and slightly golden.
6. Serve Warm
Let it sit for 5 minutes (the hardest part), then dig in!

❤️ A Small Story from My Kitchen
This casserole came from my attempt to calm a busy weeknight. I had peppers, onions, ground beef, and a craving for something cheesy. As I sautéed everything, it instantly reminded me of a classic Philly cheesesteak—minus the bread. So I grabbed the provolone (because cheese solves everything), popped it into the oven, and hoped for magic.
It came out bubbling, cheesy, and unbelievably good. The kind of dish everyone at the table stops talking for—because they’re too busy eating. And honestly, those are my favorite dinners.
