Ingredients
  

  • 1 tbsp olive oil
  • 8 oz cremini mushrooms sliced, 225g
  • 8 tbsp unsalted butter divided, 113g
  • 1 medium yellow onion chopped
  • 1 large carrot peeled and chopped
  • 3 cloves garlic minced
  • 1/4 cup all-purpose flour 30g
  • 2 1/2 cups whole milk 600ml
  • 1 tsp chicken bouillon powder
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 4 cups cooked turkey chopped or shredded, about 1.5 lbs or 680g
  • 1 1/2 cups frozen peas 220g
  • 5 cups day-old bread cut into 1-inch cubes
  • 2 tbsp grated Parmesan cheese optional
  • 1 cup shredded sharp cheddar or Monterey Jack cheese 4 oz / 113g

Instructions
 

  • Preheat your oven to 375°F (190°C).
  • Prepare the topping. In a small saucepan or microwave-safe bowl, melt 4 tablespoons of butter with 1 minced garlic clove. Place the bread cubes in a large bowl, drizzle with the garlic butter, and toss to coat. Set aside.
  • In a large, 12-inch oven-safe skillet, heat the olive oil over medium-high heat. Add the mushrooms and cook, stirring occasionally, until browned and their liquid has evaporated, about 5-7 minutes. Transfer the mushrooms to a plate.
  • Reduce the heat to medium and melt the remaining 4 tablespoons of butter in the same skillet. Add the onion and carrot and cook until softened, about 5 minutes. Stir in the remaining 2 minced garlic cloves and cook for one more minute until fragrant.
  • Sprinkle the flour over the vegetables and stir constantly for 1 minute to form a paste.
  • Slowly pour in the milk while whisking continuously to prevent lumps. Add the bouillon powder, salt, and pepper. Bring the sauce to a simmer and cook, stirring frequently, until it has thickened enough to coat the back of a spoon, about 3-4 minutes.
  • Remove the skillet from the heat. Stir in the chopped turkey, frozen peas, and the cooked mushrooms until everything is evenly combined in the sauce.
  • Arrange the prepared bread cubes evenly over the top of the filling. Sprinkle with Parmesan cheese, if using, and then the shredded cheddar cheese.
  • Bake for 20-25 minutes, until the filling is hot and bubbling and the cheese is melted and golden brown. For poultry, a safe internal temperature is 165°F (74°C). Let the pot pie rest for 5 minutes before serving.

Notes

A food thermometer should be used to ensure the filling reaches a safe internal temperature of 165°F (74°C) since it contains cooked poultry.
If you don't have an oven-safe skillet, prepare the filling on the stovetop and then transfer it to a 9x13-inch or similar 3-quart baking dish before adding the topping and baking.
For an extra-crisp topping, you can switch the oven to broil for the last 1-2 minutes of cooking. Watch it very closely to prevent it from burning.
