Instructions

  1. Peel and cube 6 medium russet potatoes. Place in a large pot, cover with cold water, and add salt. Bring to a boil, then simmer 15-18 minutes until fork-tender.
  2. Drain potatoes. Add 4 tablespoons butter, 1/2 cup warm milk or cream, and 3 ounces cream cheese. Mash until smooth and fluffy. Season with salt and pepper. Set aside.
  3. In a large skillet over medium heat, melt 2 tablespoons butter. Add diced onion and cook 3-4 minutes until translucent.
  4. Add minced garlic and thyme. Sauté 1 minute.
  5. Stir in shredded chicken and frozen peas and carrots. Sprinkle 1/4 cup flour over mixture and cook 2 minutes, stirring constantly.
  6. Gradually pour in 2 cups chicken broth, stirring to combine. Simmer 4-5 minutes until thickened.
  7. Pour in 1/2 cup heavy cream. Season with salt and pepper. Simmer 2 more minutes, then remove from heat.
  8. Preheat oven to 400°F (200°C). Grease a 9×13-inch baking dish.
  9. Spread creamy chicken filling evenly in the dish.
  10. Top with mashed potatoes, spreading edge to edge. Rough up the top with a fork for texture. Sprinkle cheddar cheese on top if desired.
  11. Bake 25-30 minutes until filling is bubbling and potato top is golden. Broil 2-3 minutes for extra browning if desired. Let rest 10 minutes before serving.
  12. While pie bakes, make the gravy: In a small saucepan, melt 2 tablespoons butter over medium heat. Whisk in 2 tablespoons flour and cook 1 minute.
  13. Slowly pour in 1 1/2 cups chicken broth, whisking constantly. Add 1/4 teaspoon pepper and salt to taste. Simmer 3-4 minutes until thickened.
  14. Serve pie slices drizzled with hot gravy.

Notes

For gluten-free, use a 1-to-1 gluten-free flour blend. For dairy-free, substitute vegan butter and non-dairy milk, and omit cheese. Let the pie rest 10 minutes before serving for best texture. Use rotisserie chicken for convenience. Customize with your favorite vegetables or leftover turkey.
