Ingredients

  • 4 tablespoons butter
  • 1 small onion, chopped
  • 2 ribs celery, chopped
  • 3 medium carrots, peeled and chopped
  • 2 teaspoons chopped fresh thyme
  • 1/4 teaspoon poultry seasoning
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • 3 tablespoons all-purpose flour
  • 2 cups low-sodium chicken broth
  • 1/2 cup whole milk
  • 1 large Yukon Gold Potato, peeled and diced
  • 3 1/2 cups cooked chicken, shredded or diced
  • 3/4 cup frozen baby peas
  • 1 tube (8-10 count) Grands biscuits
  • 1 egg, room temperature
  • 1 tablespoon cool water
  • Fresh chopped thyme or rosemary (for garnish)

Instructions

  1. Prepare the Filling:
  • Melt the butter in a Dutch oven or heavy skillet over medium heat.
  • Add the onions, celery, and carrots. Cook until the onions and celery are soft.
  • Reduce heat to low. Add thyme, poultry seasoning, salt, and pepper. Cook for 1 minute, stirring continuously.
  • Sprinkle with flour and continue cooking for 2 minutes while stirring.
  • Slowly whisk in the chicken broth and milk. Add potatoes and bring to a gentle boil. Simmer until potatoes and carrots are tender.
  1. Prebake the Biscuits:
  • Preheat the oven to 350 degrees F.
  • Cover a large baking sheet with parchment paper.
  • Open the tube of biscuits and place them on the parchment paper, a couple of inches apart.
  • Lightly beat the egg and water together to make an egg wash. Brush the tops and sides of the biscuits with the egg wash.
  • Place in the oven and prebake for 8-9 minutes.
  1. Assemble the Casserole:
  • Stir the cooked chicken and peas into the Dutch oven with the creamy gravy and vegetables.
  • Spoon the mixture into a 9×13 inch casserole dish or one of almost equivalent size.
  • Place the prebaked biscuits on top of the chicken mixture with the browned side down.
  • Brush the tops lightly with the remaining egg wash.
  1. Bake the Casserole:
  • Bake the casserole at 350 degrees F for 10 minutes.
  • Cover the casserole dish with aluminum foil and bake for another 10 minutes.

Recipe Notes

  • Cut the veggies and chicken into bite-size pieces for even distribution.
  • Use any cooked chicken—diced or shredded.
  • In a pinch, substitute fresh vegetables with 2 1/2-3 cups of frozen vegetables.
  • Adjust the consistency of the filling with more chicken broth or milk if it becomes too thick.
  • Prebaking the biscuits ensures they cook through properly and maintain their flaky texture on top of the casserole.
