Tips & Notes

  • Drain the canned tuna very well—excess liquid will make the pie watery. Pat it dry with paper towels if needed.
  • If you prefer a more textured crust, brush the top with a beaten egg before baking for extra shine and color.
  • Frozen peas are perfect here, but you can substitute fresh or canned peas if that's what you have on hand.
  • Leftovers keep well in the refrigerator for up to 2 days and reheat beautifully in a 350°F oven.
