Sear the beef before wrapping it in puff pastry to ensure it stays juicy and flavorful.

Let the beef cool completely before wrapping it in puff pastry to avoid melting the pastry.

Keep the puff pastry as cold as possible by placing a chilled chopping board in the freezer and using it as your temporary work bench as you do your final touches, i.e., rolling in your beef filet.

Ensure the puff pastry is rolled out evenly to ensure even cooking.

Brush the puff pastry with egg wash before baking to achieve a golden, shiny crust.

Use a meat thermometer to ensure the beef is cooked to your desired level of doneness, taking it slightly under as it will continue to rise in temperature while resting.

Rest the beef wellington for 10-15 minutes before slicing to allow the juices to redistribute and ensure a tender, juicy interior.
