Ingredients

Vegetables and Seasonings

  • 1 tablespoon extra-virgin olive oil
  • 8 ounces sliced cremini mushrooms
  • 1 cup chopped carrots about 3 medium
  • 1/2 cup finely diced celery about 1 large stalk
  • 2 teaspoons dried thyme
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon freshly ground black pepper

Main Ingredients

  • 1/4 cup whole wheat flour
  • 1 3/4 cups unsweetened oat milk
  • 2 cups shredded cooked chicken about 2-3 breasts
  • 3/4 cup frozen peas
  • 1/2 cup frozen pearl onions

Finishing Ingredients

  • 1 egg, beaten with 1 tablespoon water for egg wash

Instructions

Preparation Steps

  • Preheat your oven to 400 degrees F and prepare a 9-inch casserole dish with a light coating of non-stick spray.
  • In a large skillet over medium heat, warm the olive oil. Add the sliced mushrooms, and sauté for about 5-7 minutes until they are golden and tender.
  • Stir in the carrots, celery, thyme, salt, and pepper. Cook for an additional 3-4 minutes until the vegetables soften.
  • Sprinkle the whole wheat flour over the vegetable mixture and cook for 1-2 minutes, stirring well to combine.
  • Gradually whisk in the oat milk, stirring consistently until the mixture thickens, about 4-6 minutes. Add the shredded chicken, peas, and pearl onions, and mix until well combined.
  • Transfer the chicken mixture into the prepared casserole dish. Roll out the pie crust over the top, trimming the excess and gently pressing the edges to seal.
  • Brush the crust with the egg wash, creating a shiny glaze, and make several slits on top to allow steam to escape.
  • Bake in the preheated oven for about 30-35 minutes, or until the crust is golden and the filling is bubbling. Let it cool slightly before serving.
