Ingredients
Filling
- 3 tablespoons unsalted butter
- 10 ounces cremini baby bella mushrooms
- 2 medium stalks celery, diced (about a slightly heaping 1/2 cup)
- 1 ½ teaspoons garlic powder
- ½ teaspoon kosher salt
- ¼ teaspoon ground black pepper
- ¼ cup all-purpose flour (swap 1:1 gluten free flour to make GF)
- 2 cups unsweetened almond milk or milk of choice
- 1 (15-ounce) can reduced sodium white beans, rinsed and drained (or 1 ½ cups cooked white beans)
- 1 (12-ounce) bag mixed peas and carrots or mixed frozen vegetables of choice (no need to thaw)
- ½ cup frozen pearl onions (no need to thaw)
- 1 tablespoon chopped fresh thyme or 1 teaspoon dried thyme
- 1 tablespoon balsamic vinegar
Pie Crust and Topping
- 1 prepared pie crust (dairy free if needed; used whole wheat pie crust)
- 1 egg, lightly beaten with 1 tablespoon water (to create an egg wash)
Instructions
- Prepare Oven and Pie Dish: Place an oven rack in the lower third and preheat the oven to 425°F. Lightly coat a 9-inch pie dish with baking spray and set aside.
- Sauté Mushrooms and Vegetables: Heat a large Dutch oven or heavy-bottomed pan over medium-high heat. Add butter, then mushrooms, and cook for 6 minutes until beginning to brown, stirring occasionally. Add diced celery, garlic powder, salt, and pepper; cook about 3 more minutes until mushrooms brown further and celery softens.
- Create the Sauce: Sprinkle flour over vegetables and cook 2 minutes until white disappears and vegetables appear dry. Slowly pour in almond milk in small splashes, stirring constantly. Bring to a low boil, scraping browned bits from the pan bottom. Let bubble until thickened for 3 to 5 minutes, stirring frequently to prevent sticking.
- Add Remaining Filling Ingredients: Stir in white beans, peas and carrots, frozen pearl onions, thyme, and balsamic vinegar until well combined.
- Assemble the Pie: Spoon the filling evenly into the prepared pie dish. Roll out pie dough into a circle large enough to cover the dish. Brush edges of the dish with egg wash, place dough over the top, allowing it to overhang by 1/2 inch. Trim edges and gently press dough onto sides to seal. Brush entire top with remaining egg wash and cut 5 slits in the crust to vent steam.
- Bake the Pie: Place pie dish on a parchment-lined rimmed baking sheet. Bake for 20 to 25 minutes until the filling is hot and bubbly and crust is deeply golden, rotating the pan halfway through baking.
- Rest and Serve: Let the pot pie rest for a few minutes out of the oven, then serve hot for a comforting meal.
Notes
- TO MAKE AHEAD: Prepare the filling ahead and refrigerate up to 3 days or freeze up to 3 months (thaw overnight before reheating). Add crust just before baking.
- TO STORE: Best eaten the day made for crisp crust. Leftovers keep refrigerated for up to 4 days.
- TO REHEAT: Warm gently in microwave or oven at 350°F until heated through.
- TO MAKE GLUTEN FREE: Use gluten free flour and a gluten free pie crust.
- TO MAKE VEGAN: Substitute butter with olive oil and use dairy-free pie crust.
