Build the creamy sauce.
1.Sprinkle 1/4 cup of all-purpose flour over the softened vegetables. Stir continuously and cook for 1 minute to remove the raw flour taste.2.Gradually pour in the milk and water while whisking constantly to prevent lumps.3.Bring the mixture to a gentle simmer and cook until thickened enough to coat the back of a spoon (3-4 minutes).4.Stir in 0.25 teaspoon of salt and a pinch of black pepper.TIPWhisking continuously while adding the liquid is the secret to a smooth, lump-free sauce. - assemble · ~2 min
Assemble the casserole base.
1.Remove the skillet from the heat. Fold the seared chicken and thawed peas into the creamy vegetable mixture.2.Pour the filling into a 9x13 inch baking dish, spreading it into an even layer. - mix · ~5 min
Make the drop biscuit topping.
1.In a mixing bowl, whisk together 1.5 cups all-purpose flour, baking powder, and a pinch of salt.2.Add the cold butter cubes. Use a pastry cutter or your fingertips to work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces.3.Pour in the cold buttermilk. Stir gently with a fork just until the dough comes together into a sticky mass. Do not overmix.TIPKeep the butter and buttermilk as cold as possible. The steam from the melting butter in a hot oven is what makes the biscuits fluffy. - assemble · ~1 min
Top the casserole with biscuit dough.
Using two spoons or a cookie scoop, drop 8 equal portions of the biscuit dough over the surface of the hot chicken filling, spacing them slightly apart. The biscuits will expand as they bake.
- bake · ~25 min
Bake until golden and bubbly.
Place the casserole dish on the center rack of the preheated oven. Bake for 20-25 minutes, or until the filling is bubbling at the edges and the biscuit tops are puffed and deeply golden brown.
TIPIf the biscuits brown too quickly before the filling bubbles, tent the dish loosely with aluminum foil. - rest · ~10 min
Rest before serving.
Remove the casserole from the oven and let it sit at room temperature for 5-10 minutes to set up.
TIPResting prevents the filling from being too runny when you scoop the first serving. - garnish
Garnish with fresh parsley and serve hot.
Sprinkle the chopped parsley over the top and scoop generous portions onto plates.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the chicken dry before searing to ensure a good brown crust.
- 2Work the butter into the flour until pea-sized; this creates flaky biscuits.
- 3Use cold buttermilk and butter for the biscuit topping—warm ingredients yield dense biscuits.
- 4Whisk the milk and water into the roux slowly to avoid lumps in the sauce.
- 5Let the casserole rest 5-10 minutes after baking so the filling sets before serving.
- 6If the biscuit tops brown too fast, tent the dish with foil for the remaining bake time.
