# Expert Advice:

01 -
  • It's the kind of meal that feels fancy enough for company but requires no fancy techniques.
  • Everything comes together in one dish, so you're not juggling five pans at dinner time.
  • The contrast between the savory, umami-rich filling and the buttery potato top never gets old.
02 -
  • Don't skip draining the potatoes thoroughly—water is the enemy of creamy mashed potatoes, and it ruins the contrast between the filling and the topping.
  • The flour step is essential; it's what transforms beef broth and vegetables into a proper sauce instead of a soupy mess.
  • Let the pie rest for 5 to 10 minutes after baking before serving; it makes plating easier and lets all the flavors settle together beauli>
03 -
  • Warm your milk before stirring it into the potatoes—it makes them come together faster and creates a silkier texture.
  • Don't overmix the mashed potatoes or they'll become gluey; fold in the butter and milk gently and stop as soon as everything is combined.
