Ingredients:
- cups (240g) All-Purpose Flour (for topping)
- Tbsp Baking Powder (for topping)
- tsp Fine Sea Salt (for topping)
- Tbsp (85g) very cold Unsalted Butter, cubed (for topping)
- /4 cup (180ml) Cold Whole Milk (for topping)
- Tbsp Fresh Parsley, chopped (optional)
- cups (350g) Cooked Chicken, shredded or cubed
- Tbsp Unsalted Butter (for filling)
- medium Yellow Onion, finely diced
- cup (125g) Carrots, diced small
- medium Celery Stalks, diced small
- /4 cup (30g) All-Purpose Flour (for roux)
- 1/2 cups (360ml) Low Sodium Chicken Broth
- /2 cup (120ml) Heavy Cream
- tsp Fresh Thyme Leaves
- Salt and Black Pepper, to taste
- cup (150g) Frozen Peas
- large egg + 1 Tbsp water (for egg wash)
Instructions:
- Preheat oven to 400°F (200°C). Lightly grease a 9x13 inch baking dish.
- Prepare the filling base: In a medium saucepan, melt the 4 Tbsp of butter over medium heat. Add onions, carrots, and celery. Sauté until softened (about 7-8 minutes).
- Sprinkle the 1/4 cup of flour over the vegetables. Cook, stirring constantly, for 1 minute to cook out the raw flour taste (creating the roux).
- Gradually whisk in the chicken broth until smooth. Bring to a simmer, stirring until the sauce thickens slightly. Stir in the heavy cream, thyme, salt, and pepper. Cook for 2 minutes until thickened enough to coat the back of a spoon.
- Remove from heat. Fold in the cooked chicken and frozen peas. Pour the entire mixture into the prepared baking dish.
- Make the biscuit topping: In a large bowl, whisk together the 2 cups of flour, baking powder, and salt for the topping. Cut in the 6 Tbsp of cold, cubed butter using a pastry blender or two knives until the mixture resembles coarse crumbs with some pea-sized pieces remaining.
- Stir in the cold milk and optional parsley quickly, just until a shaggy dough forms. Do not knead.
- Drop spoonfuls (about 2 tablespoons each) of the biscuit dough randomly over the top of the chicken filling, leaving small gaps between them.
- Lightly whisk the egg wash ingredients and brush lightly over the tops of the biscuits.
- Bake for 35–40 minutes, or until the filling is bubbling vigorously and the biscuit tops are deeply golden brown and cooked through.
- Let rest for 10 minutes before serving hot.
