FAQ

Can I use different potatoes? Yes—Yukon golds hold their shape and turn creamy. Dice to ¾-inch for even cooking.

Will raw ham work? Use fully cooked ham. If using uncooked, pan-sear until cooked through.

Can I add more protein? Fold in cooked bacon during the last 30 minutes.

How do leftovers hold up? Refrigerate up to 4 days. Reheat gently with a splash of milk.

Can I prep this overnight? Yes—prep ingredients separately, combine in the morning, and cook.
