Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently to avoid drying out the beef.
A large skillet or grill pan works best for cooking fillet steaks. Make sure it’s preheated to ensure a good sear.
Greek yogurt or heavy cream can be used as a substitute for sour cream in the olive oil mash, though they will alter the flavor and texture slightly.

- Season well.: Don't skimp on seasoning both the meat and the potatoes to bring out the full range of flavors.
