CHEF NOTES:

Make-Ahead: You can caramelize the onions and meat 2-3 hours ahead of serving. Simply keep them warm in a crockpot or in a pan over low heat. The meat is thin enough that it will stay tender.

How to Reheat the Steak: Add the desired amount of steak and onions to a small frying pan over low heat and cook until hot. You can also heat in a microwave-safe bowl until hot.

How to Reheat the Sauce: Add the desired amount to a small saucepan and heat over low heat while occasionally stirring until hot.

How to Store: Keep the cooked meat and onions separate from the buns and sauce and cover in the refrigerator for up to 4 days. The sauce will keep for up to 5 days covered in the fridge.

How to Freeze: Keep the cooked meat and onions separate from the buns and sauce and cover in the freezer for up to 2 months. Thaw for 1 day in the refrigerator before reheating.

Tools Needed: You can use a flat top pan or a regular large frying pan. You will also need a metal spatula.
