Ingredients
  

  • 2 lbs Russet or Yukon Gold potatoes peeled and cubed; Yukon Gold recommended for creamier mash
  • 4 tbsp unsalted butter for the mash
  • 0.5 cup milk or heavy cream warmed slightly before adding
  • 0.5 tsp garlic powder for the mash
  • salt and black pepper to taste throughout
  • 1.5 lbs boneless skinless chicken breasts or thighs cut into bite-sized pieces; thighs recommended
  • 1 tbsp olive oil
  • 1 small onion diced
  • 2 large carrots diced
  • 2 stalks celery diced
  • 1 cup frozen peas or mixed vegetables
  • 3 cloves garlic minced
  • 3 tbsp all-purpose flour
  • 1.5 cups chicken broth low-sodium recommended
  • 1 tsp dried thyme or rosemary
  • 1 tbsp Worcestershire sauce

Equipment

  • Large oven-safe skillet or Dutch oven
  • Large pot for potatoes
  • Potato masher
  • whisk

Method
 

  1. Cook the cubed potatoes in salted boiling water for 12 to 15 minutes until completely fork-tender. Drain thoroughly and mash with butter, warmed milk or cream, garlic powder, salt, and pepper until smooth. Set aside.
  2. Preheat the oven to 375°F (190°C).
  3. Heat olive oil in a large oven-safe skillet over medium-high heat. Add the chicken pieces and cook for 4 to 5 minutes until browned on all sides. Remove to a plate.
  4. In the same pan, sauté the onion, carrots, and celery over medium heat for 5 to 7 minutes until softened. Add the minced garlic and cook for 1 more minute.
  5. Sprinkle the flour over the vegetables and stir constantly for 1 full minute. Slowly whisk in the chicken broth, Worcestershire sauce, and dried thyme. Simmer, stirring, until the gravy thickens to coat the back of a spoon.
  6. Fold in the browned chicken and frozen peas. Simmer on low for 2 minutes. Taste and adjust seasoning.
  7. Spread the mashed potatoes evenly over the filling to the edges. Use a fork to create ridges across the surface.
  8. Bake uncovered for 20 to 25 minutes until the gravy bubbles at the edges and the potato peaks are golden brown. Rest for 5 minutes before serving.

Notes

Gravy Thickness: The gravy must coat the back of a spoon before the potato topping goes on. Too-thin gravy causes the potato layer to sink in. Lumpy Gravy Fix: Add broth in a slow stream while whisking continuously. Strain through a fine mesh sieve if lumps form. Cheesy Crust: Scatter 1/2 cup shredded white cheddar or Parmesan over the potato ridges before baking for a golden, caramelized cheese crust. Rotisserie Shortcut: Skip browning and add 2 cups shredded rotisserie chicken directly to the finished gravy. Make Ahead: Assemble, cover, and refrigerate for up to 24 hours. Add 10 minutes to the covered bake time. Freeze Unbaked: Wrap tightly and freeze for up to 2 months. Bake from frozen covered at 375°F for 45 minutes then uncovered for 15 minutes. Storage: Refrigerate for up to 4 days.
