Chicken Pot Pie Filling

• 3 teaspoons canola oil, divided
• 1 cup frozen pearl onions, thawed
• 1 cup peeled baby carrots
• 10 ounces cremini mushrooms, halved
• 2 1/2 cups reduced-sodium chicken broth, divided
• 1/4 cup cornstarch
• 2 1/2 cups diced cooked chicken, or turkey
• 1 cup frozen peas, thawed
• 1/4 cup reduced-fat sour cream
• 1/4 teaspoon salt
• Freshly ground pepper, to taste

To prepare filling: Heat 1 teaspoon oil in a large skillet or Dutch oven over medium-high heat. Add onions and carrots; cook, stirring, until golden brown and tender, about 7 minutes. Transfer to a bowl. Heat the remaining 2 teaspoons oil in the pan over medium-high heat. Add mushrooms and cook, stirring often, until browned and their liquid has evaporated, 5 to 7 minutes. Return the onions and carrots to the pan. Add 2 cups broth and bring to a boil; reduce heat to a simmer. Mix cornstarch with the remaining 1/2 cup broth; add to the pan and cook, stirring, until the sauce thickens. Stir in chicken (or turkey), peas, sour cream, salt and pepper. Transfer the filling to a 2-quart baking dish.


Place filling in prepared pie shells
Bake the potpie until the topping is golden and the filling is bubbling, 30 to 35 minutes. Let cool for 10 minutes before serving.
