Chef Emma’s Helpful Tips

Make-Ahead Perfection: This casserole can be prepared in advance and stored in the refrigerator. Just bake it when you’re ready to serve—it’s a lifesaver on busy days!
Slicing the Steak: For the best results, freeze the steak for about 30 minutes before slicing. It firms up, making it easier to cut into thin strips.
Ingredient Swaps: If you don’t have steak on hand, ground beef works beautifully as a substitute, cooking up quickly and soaking in all the delicious flavors.
Storing Leftovers: Any leftovers can be stored in an airtight container for up to three days. Just reheat in the oven for the best texture—you want that cheese to get melty again!
