This cozy chicken pot pie casserole combines creamy chicken filling with golden biscuit topping for a quick, nostalgic meal that’s full of comfort. Perfect for busy weeknights or lazy weekends, it’s a modern twist on a classic dish — easy to make, even easier to love.
Preheat oven to 400°F. Lightly grease a 9x13-inch baking dish.
Heat olive oil in a large skillet over medium heat. Add onion, carrots, and celery. Cook for 5–6 minutes until softened.
Add butter to skillet and melt. Stir in flour to form a roux. Cook for 1–2 minutes, stirring constantly.
Slowly whisk in chicken broth. Once thickened slightly, add milk and stir until creamy.
Stir in thyme, salt, pepper, and frozen peas. Fold in the cooked shredded chicken.
Transfer mixture to prepared baking dish. Top evenly with biscuit dough.
Bake for 20–25 minutes until biscuits are golden and filling is bubbling.
Let cool for 5 minutes. Garnish with fresh parsley and serve warm.
Notes
Use Greek yogurt or dairy-free alternatives for a lighter version. Leftovers keep well and flavors deepen the next day. Freeze before or after baking for easy future meals.
