Tips

Tip 1

Do not fill the pastry while the filling is hot; cool to warm temperature first to avoid soggy pastry.

Tip 2

Mash at least half the roasted squash while leaving some pieces for texture variation in the filling.

Tip 3

Use a fork to create an even seal around all edges to prevent pastry splitting during baking.

Tip 4

Cut steam vents after assembling to avoid them closing over during the bake.

Good to Know

Storage

Cover and refrigerate uncooked wellington for up to 1 day before baking. Store baked wellington in an airtight container in the refrigerator for up to 2 days; reheat gently.

Make Ahead

Prepare filling and cool completely up to 2 days ahead. Assemble wellington up to 4 hours before baking; cover with cling film and refrigerate.

Serve With

Serve hot with roast potatoes, vegetables, and gravy.

Common Mistakes

Watch

Do not skip cooling the filling before assembly to avoid pastry becoming soggy from excess moisture.

Watch

Do not forget to cut steam vents in the top to allow steam to escape and prevent pastry bursting.

Watch

Do not brush pastry too heavily with oil; use a light hand for even golden browning without burning.
