Ingredients

4 cups cooked chicken, shredded*
6 Tbsp unsalted butter, plus ½ Tbsp extra for brushing biscuits
1 medium yellow onion (about 1 cup), chopped
2 medium carrots (about 1 cup), thinly sliced
8 oz white or brown mushrooms, stems removed, sliced
3 garlic cloves, minced
⅓ cup all-purpose flour
2½ cups chicken stock
½ cup heavy cream
2 tsp fine sea salt, or to taste
¼ tsp black pepper, plus extra for garnish
1 cup frozen peas (no need to thaw)
¼ cup parsley, finely chopped
10 homemade biscuits

*Rotisserie chicken or any cooked chicken breast or thigh meat works well.

Instructions

Preheat the Oven
Preheat your oven to 400°F. Butter a 9×12-inch casserole dish and set aside.
Prepare the Filling
In a Dutch oven or large pot, melt 6 Tbsp butter over medium heat. Add the chopped onions and sliced carrots. Sauté for 8 minutes until softened.
Add the mushrooms and garlic, and cook for another 3–5 minutes until the mushrooms are tender.
Make the Gravy
Stir in the flour and cook for 2 minutes, stirring constantly. Gradually whisk in the chicken stock and heavy cream. Bring to a simmer and cook for 1 minute until the mixture thickens to a gravy-like consistency. Season with 2 tsp salt and ¼ tsp black pepper (adjust to taste).
Finish the Filling
Stir in the shredded chicken, frozen peas, and parsley. Mix well, then remove from heat and cover to keep warm.
Assemble the Casserole
Pour the chicken mixture into the prepared casserole dish. Arrange the biscuit dough evenly on top in a single layer.
Bake
Bake uncovered at 400°F for 25–28 minutes, or until the biscuits are puffed and golden brown.
Finish and Serve
Brush the tops of the biscuits with ½ Tbsp melted butter. Sprinkle with a pinch of kosher salt and cracked pepper if desired. Serve warm.

Tips

Use leftover rotisserie chicken to save time.
Slice vegetables evenly for even cooking.
If the gravy thickens too much, add a splash of broth to loosen before transferring to the baking dish.
Don’t overbake the biscuits—check for golden tops and flaky layers.
