Use store-bought crusts or make your own pie crust if you prefer. I like a thick filling; add more liquid for a thinner sauce.

Pouring hot, steaming filling directly into pie pastry guarantees a soggy bottom crust because the residual heat melts the shortening or butter before the dough hits the oven. British working-class cooks developed enclosed meat pies in the nineteenth century primarily as portable, durable rations, using thick pastry walls to preserve the contents without refrigeration. Achieving that structural integrity at home requires managing moisture at every stage of preparation.
Cook the leeks, carrots, celery, and thyme over medium heat for approximately 10 minutes until the cellular walls soften and release their moisture. Sauté the sliced mushrooms separately until browned and their liquid completely evaporates, which concentrates their umami compounds. When making the velouté base, cook the flour and butter roux for precisely two minutes to eliminate the raw starch flavor before whisking in chicken stock and heavy cream. Spreading the completed filling onto a sheet pan cools it rapidly before it touches the pastry.
