Instructions

Caramelize the Onions: Slice the onions thinly and cook them slowly over low heat in butter until they turn a deep golden brown and become sweet and tender. This process builds the foundational flavor for the filling.
Sauté the Mushrooms: Add the sliced mushrooms to the caramelized onions and cook over medium heat until their moisture evaporates and they become browned and fragrant.
Prepare the Sauce: Sprinkle the flour over the cooked onions and mushrooms, stirring to coat them evenly. Gradually add the vegetable broth and milk or cream, stirring constantly to form a smooth, thick sauce. Season with thyme, salt, and pepper to taste.
Assemble the Pot Pie: Transfer the filling into a pie dish. Cover with the chilled pie crust, trimming and crimping the edges to seal. Cut vents in the top crust to allow steam to escape during baking.
Bake to Perfection: Bake in a preheated oven at 375°F (190°C) for 35–45 minutes, or until the crust is golden brown and flaky, and the filling is hot and bubbling.

Notes

Caramelize onions slowly over low heat to avoid bitterness and develop deep sweetness.
Ensure mushrooms are dry before cooking to achieve perfect browning and prevent sogginess.
Do not overfill the pie dish to prevent spills while baking.
Keep the pie crust chilled before baking for a crisp, flaky texture.
Use fresh herbs when possible for brighter, more vibrant flavors.
