Method
- 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.
- Preheat the oven to 375°F (190°C).
- 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.
- 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.
- 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.
- Fold in the browned chicken and frozen peas. Simmer on low for 2 minutes. Taste and adjust seasoning.
- Spread the mashed potatoes evenly over the filling to the edges. Use a fork to create ridges across the surface.
- 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.
