Philly Cheesesteak Cheese Sauce with Provolone and American
This cheese sauce for Philly cheesesteak turns griddled steak and onions into a sandwich that is special occasion worthy. It is glossy, made with real cheese, and ready in about ten minutes. No Velveeta, no Cheez Whiz, no grainy science experiments. My kids have been known to claim the leftovers for breakfast, which I think tells you everything.
Heat the evaporated milk in a small saucepan over medium heat.
In a small bowl, stir together the water and cornstarch. Add to the evaporated milk.
Add the American cheese and provolone cheese to the evaporated milk, and stir until the cheese melts. Whisk in the Worcestershire sauce, mustard, garlic powder, salt and fresh ground black pepper.
Keep warm until ready to serve. If you want to make the sauce thinner, add milk, ¼ cup at a time until the desired consistency is achieved.
Notes
The sauce is intentionally thick. Thin with milk right before serving, especially if it's been sitting more than 20 minutes.
Buy block cheese or sliced cheese and dice it yourself. Pre-shredded cheese has anti-caking agents that fight a smooth melt.
Store leftovers in a jar in the fridge up to 1 week. Reheat gently over low heat or in 30-second microwave bursts, whisking in milk to bring it back.
