Preparing the Casserole
- Preheat the Oven:
- Preheat your oven to 400°F (200°C).
- Cook the Vegetables:
- In a large skillet, heat olive oil or butter over medium heat. Add the chopped onion and cook until translucent, about 5 minutes. Add the minced garlic and cook for another 1 minute.
- Make the Sauce:
- Stir in the flour and cook for 1-2 minutes until the mixture becomes slightly golden. Gradually whisk in the chicken broth and heavy cream. Continue to cook, stirring frequently, until the sauce thickens, about 5-7 minutes.
- Combine Ingredients:
- Add the cooked chicken, frozen peas and carrots, and cooked potatoes (if using) to the sauce. Stir in the dried thyme, rosemary, salt, and pepper. Cook for another 2-3 minutes until everything is well combined and heated through.
- Transfer to Casserole Dish:
- Pour the chicken mixture into a greased 9×13-inch casserole dish.
Making the Biscuit Topping
- Prepare the Biscuit Dough:
- In a large bowl, whisk together the flour, baking powder, and salt. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
- Add Milk:
- Pour in the milk and stir until just combined. The dough will be somewhat sticky.
- Add the Biscuit Topping:
- Drop spoonfuls of the biscuit dough over the chicken mixture in the casserole dish. Spread the dough out as evenly as possible, but it doesn’t need to cover the entire surface.
Baking the Casserole
- Bake:
- Place the casserole in the preheated oven and bake for 25-30 minutes, or until the biscuit topping is golden brown and the filling is bubbling.
- Cool Slightly:
- Let the casserole cool for about 10 minutes before serving to allow the filling to set.
Tips for Success
- Chicken: Use rotisserie chicken for extra flavor and convenience, or cook and shred your own chicken.
- Vegetables: Customize the vegetables according to your preference or what you have on hand.
- Biscuit Topping: For a more golden top, brush the biscuit dough with a little melted butter before baking.
- Storing: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave.
