storage/reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm the steak and mashed potatoes separately in the microwave or on the stovetop over low heat. Add a splash of milk to the mash if it becomes too thick. Avoid overcooking the steak when reheating to preserve tenderness.
FAQs
Can I use a different cut of beef?
Yes, ribeye, strip steak, or tenderloin also work well. Just ensure the pieces are cut evenly for uniform cooking.
What’s the best potato for mashing?
Yukon Gold or Russet potatoes yield a creamy texture and absorb butter and milk well.
Can I make this recipe ahead of time?
You can prepare the mashed potatoes ahead and reheat when ready. Cook the steak just before serving for best texture.
How do I keep the steak bites from overcooking?
Sear in small batches over high heat and avoid overcrowding the pan. Remove promptly once done.
