How to Make Chicken Pot Pie Casserole
Step 1: Prepare the Oven and Dish
Preheat your oven to 400°F. Next, butter a 9x13 or 9x12 casserole dish to prevent sticking.
Step 2: Sauté the Vegetables
Melt 6 tablespoons of unsalted butter in a Dutch oven over medium heat. Once melted, add the chopped onions and carrots, sautéing them for about 8 minutes until they soften. Add sliced mushrooms and minced garlic, cooking for another 3 to 5 minutes.
Step 3: Make the Base
Stir in the flour and cook for 2 minutes to eliminate the raw flavor. Gradually add chicken stock and heavy cream, stirring until the mixture comes to a simmer and thickens. Season with sea salt and black pepper to taste.
Step 4: Combine Ingredients
Add the shredded chicken, frozen peas, and chopped parsley to the thickened mixture. Remove the pot from the heat once everything is mixed in.
Step 5: Transfer to Casserole Dish
Spread the chicken and vegetable mixture evenly into the prepared casserole dish. Top it off with the biscuits, arranging them in a single layer.
Step 6: Bake the Casserole
Bake the casserole uncovered for 25 to 28 minutes or until the biscuits puff up and turn golden brown.
Step 7: Finish and Serve
Before serving, brush the biscuits with the remaining melted butter for extra flavor. Serve hot and enjoy the comforting goodness of your Chicken Pot Pie Casserole.

Pro Tips from My Kitchen
✓ Mind the Butter – Make sure to use unsalted butter for the filling, allowing you more control over the saltiness of the meal.
✓ Testing for Thickness – The mixture should be thick enough to coat the back of a spoon when you finish simmering it. Adjust with more flour if necessary.
✓ Reheating Leftovers – If you have leftovers, store them in an airtight container in the fridge. To reheat, cover and warm in the oven at 350°F until heated through.
✓ Avoid Soggy Biscuits – If the biscuits seem soggy after baking, ensure your filling is thick enough before adding them. This keeps them flaky.
✓ Perfect Pairings – Serve with a simple side salad or steamed vegetables to balance the richness of the casserole. A light white wine also complements the flavors nicely.
