your pan is not large enough. The internal temperature for steak is typically 135°F (57°C) for medium-rare, 145°F (63°C) for medium, and 160°F (71°C) for well-done.
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium heat for the steak bites and in an oven or toaster oven for the potatoes to maintain texture. Microwaving is not recommended as it will make the potatoes soft and the steak tough.
