Tips for the Best 3-Ingredient Corned Beef & Potato Bake


A few simple tricks will help you achieve perfectly crispy potatoes and tender corned beef every time.

  • Cut the potatoes into evenly sized pieces so they cook at the same rate.
  • Spread everything in a single layer on the baking sheet to encourage browning instead of steaming.
  • Toss the potatoes well with the oil before adding the corned beef.
  • Flip everything halfway through baking for crispy edges on all sides.
  • Let the bake rest for 5 minutes before serving to allow the potatoes to crisp up even more.
  • If your corned beef is packed in large chunks, break it into bite-sized pieces before mixing.
