Ingredients
Scale
Caramelized Onions
- 2 large onions, thinly sliced
- 2 tbsp butter or oil
Vegetable Filling
- 3 cups assorted mushrooms (cremini, button, shiitake), diced
- 2 garlic cloves, minced
- 1 shallot, diced
- 1 tbsp fresh thyme leaves
- 2 tbsp chopped fresh parsley
Sauce
- 3 tbsp butter
- 3 tbsp all-purpose flour (or gluten-free flour for GF version)
- 2 cups vegetable broth
- 1/2 cup heavy cream or plant-based cream alternative
- Salt and black pepper, to taste
Pie Crust
- 1 double crust pie dough (buttery or plant-based for vegan; gluten-free crust as needed)
Instructions
- Caramelize the Onions: Slowly cook thinly sliced onions in butter or oil over low heat for 25-30 minutes until they turn sweet and golden, creating the essential flavor base.
- Sauté Mushrooms and Aromatics: Add diced mushrooms, garlic, and shallots to the pan with caramelized onions. Cook until mushrooms release moisture and brown for maximum flavor.
- Make the Roux and Sauce: Push vegetables aside, melt butter in the pan, and whisk in flour to form a roux. Gradually add vegetable broth and cream, stirring constantly until sauce thickens and coats the filling beautifully.
- Assemble the Pie: Transfer the filling into a pie dish lined with one layer of pie crust. Cover with the second crust, seal edges, and make decorative slits on top to vent steam.
- Bake Until Golden: Preheat oven to 375°F (190°C). Bake the pot pie for 30-40 minutes until crust is golden and flaky and the filling bubbles through vents.
Notes
- Take your time caramelizing onions to develop natural sweetness without burning.
- Use a mix of mushrooms for added texture and flavor depth.
- Don’t overfill the pie to ensure even baking and avoid overflow.
- Keep pie dough chilled before baking to maintain flakiness.
- Let the pie rest 10-15 minutes after baking so the filling sets properly.
- Fresh mushrooms are preferred, but if using frozen, thaw and drain well.
- The recipe can be made vegan by using plant-based butter and cream.
- The pie can be made gluten-free by substituting the crust and ensuring gluten-free ingredients.
- Leftovers store refrigerated up to 3 days; unbaked pie can be frozen for up to one month.
