How to Make Chicken Pot Pie Casserole Recipe

Step 1: Prep your veggies and herbs

Start by dicing the onion, slicing the carrots and celery into half-inch pieces, and mincing the garlic. If you’re using fresh thyme, strip the leaves and chop coarsely—you’ll get a fresher, more fragrant note than dried. Prepping everything before you heat your skillet makes the cooking process smooth and fun, trust me on this.

Step 2: Sauté until fragrant and tender

Melt 4 tablespoons of butter in a large skillet over medium-high heat and toss in the onion, carrots, celery, thyme, salt, and pepper. Sauté them until they start to soften and get a little golden—usually about 5 to 7 minutes. This step builds flavor and softens the veggies just right for the creamy filling.

Step 3: Make the creamy sauce

Sprinkle the flour over the cooked veggies and stir well to coat everything evenly. Cook this mixture for about 30 seconds to a minute, until it smells nutty and you don’t see any dry spots. Then pour in the chicken broth slowly, followed by the milk, scraping up those delicious browned bits from the pan. Bring the mixture to a boil, then reduce to a simmer and cook until thickened—about 4 to 5 minutes. This velvety sauce is what makes this casserole so comforting.

Step 4: Add chicken, peas, and season to taste

Stir in your shredded or diced cooked chicken along with the frozen peas, which will thaw right in the warm filling. Give it a taste and adjust salt and pepper—you want that balance just right before baking. I always double-check here because seasoning can make or break a dish.

Step 5: Assemble and bake your casserole

Transfer the filling to a 9×13-inch baking dish and spread it evenly. Open your can of refrigerated jumbo biscuits, separate them, and arrange in a single layer on top of the filling. Bake at 375°F for 20 to 30 minutes, rotating the pan halfway through. If the biscuits start browning too fast, tent a piece of aluminum foil over the top to prevent burning.

Step 6: Butter those biscuit tops

Once the biscuits are golden and fully cooked, melt the remaining 2 tablespoons of butter and brush it over the tops to add that shiny, delicious finish. This little step makes it look and taste extra special, like something out of a restaurant.

How to Serve Chicken Pot Pie Casserole Recipe

Garnishes

I usually sprinkle a little fresh chopped parsley or thyme over the finished casserole for color and a fresh herbal lift. Sometimes, I add a pinch of flaky sea salt on the biscuit tops right after buttering for that little burst of texture and flavor. It’s a simple touch, but guests notice!

Side Dishes

This recipe is filling enough to stand on its own, but I like pairing it with a crisp green salad or some roasted Brussels sprouts to add a fresh, crunchy contrast. Steamed green beans or a light cucumber salad also work well for a balanced meal.

Creative Ways to Present

For a fun twist during holidays or dinner parties, I divide the casserole into individual ramekins and top each with a biscuit. It feels more personal and “special occasion,” plus it’s just plain cute! You can also add small biscuit cutouts shaped with cookie cutters on top for a festive look.

Make Ahead and Storage

Storing Leftovers

I usually let the casserole cool completely, then cover it tightly with foil or plastic wrap before refrigerating. It keeps well for up to 3 days, and the flavors even seem to meld and improve overnight. Just remember to cool it before storing so it stays fresh.

Freezing

Freezing this casserole works, but I recommend freezing before baking for the best texture. Assemble the filling in a freezer-safe dish and place the uncooked biscuits on top, cover tightly, and freeze. When ready, bake from frozen—just add extra baking time and watch the biscuit browning closely.

Reheating

Reheat leftovers in a 350°F oven to keep biscuits from getting soggy—about 15 to 20 minutes covered with foil. I avoid microwaving when possible, since it can make the biscuit topping chewy rather than flaky and crisp.
