Ingredients You’ll Need

The beauty of this Chicken Pot Pie Casserole Recipe lies in its simple, fresh ingredients that come together beautifully to build flavor and create a cozy meal. When shopping, look for fresh veggies and quality chicken to really make this dish shine.

• Yellow onion: Adds sweetness and depth; I like to dice it finely so it cooks evenly with the carrots and celery.
• Carrots: They bring a subtle sweetness and bright color — slicing into uniform pieces helps them soften perfectly.
• Celery: Gives a nice crunch and savory undertone, balancing the creamy filling.
• Garlic cloves: Minced fresh garlic gives that aromatic punch you want in comfort dishes.
• Fresh thyme or dried thyme: This herb really lifts the flavor; fresh is my go-to if it’s in season.
• Unsalted butter: Use good quality for a richer flavor and to control salt levels.
• Kosher salt and freshly ground black pepper: Season well to bring out the veggies and chicken.
• All-purpose flour: This is your thickener to get that creamy pot pie texture without any lumps.
• Low-sodium chicken broth: Keeps the filling flavorful but not too salty.
• Whole or 2% milk: Adds creaminess plus helps create the sauce that holds it all together.
• Cooked boneless chicken: Shredded or diced – leftover rotisserie chicken works beautifully here.
• Frozen peas: Keep them frozen until adding, or they’ll get mushy — I love how they add pops of freshness.
• Refrigerated jumbo or grand-size biscuits: These make the perfect topping that’s flaky and golden without the hassle of homemade dough.

Variations

I love how flexible this Chicken Pot Pie Casserole Recipe is, so feel free to personalize it! Over the years, I’ve played around with different veggies and toppings to keep it fresh and exciting for my family.

• Vegetable swaps: Sometimes I swap peas for green beans or use corn for a touch of sweetness, and it’s just as delicious.
• Dairy-free option: I’ve used plant-based milk and vegan butter for friends with sensitivities, and it turns out wonderfully creamy.
• Chicken alternatives: When I want a twist, turkey or even cooked mushrooms make great substitutes.
• Homemade biscuit topping: For a special occasion, I make my own biscuit dough—though the refrigerated version saves so much time!

How to Make Chicken Pot Pie Casserole Recipe

Step 1: Prep Your Veggies for Maximum Flavor

Start by dicing your yellow onion, chopping your carrots and celery into uniform ½-inch pieces, and mincing garlic. The key here is consistency so everything cooks evenly. Don’t skip picking fresh thyme leaves if you can—that herb makes a big difference in flavor depth.

Step 2: Sauté to Build the Base

Melt 4 tablespoons of butter over medium-high heat in a large skillet, then add your onion, carrots, celery, thyme, salt, and pepper. I wait to add the garlic until just before the flour so it doesn’t burn. Let the veggies soften and brown slightly—about 5 to 7 minutes—which adds that lovely caramelized flavor that makes your filling taste homemade and rich.

Step 3: Make the Creamy Filling

Stir in the flour and garlic, coating the veggies well. Cook it for 30 seconds to one minute to remove the raw flour taste. Then slowly pour in the chicken broth and milk, scraping the pan bottom to loosen all those tasty browned bits. Bring it up to a simmer and cook for 4 to 5 minutes until it’s thick enough to coat the back of a spoon. This step might seem small, but it’s what makes the filling silky and indulgent.

Step 4: Add the Chicken and Peas

Shred or dice your cooked chicken into bite-sized pieces — I often use leftover rotisserie chicken here. Toss the chicken and frozen peas directly into the skillet and stir well. Taste and adjust seasoning with salt and pepper. This is your moment to get the flavor just right before layering it into your baking dish.

Step 5: Assemble and Bake

Transfer the filling evenly to a 9×13-inch baking dish. Open your refrigerated biscuits and arrange them in a single layer on top — don’t overlap because they need room to rise and get golden. Bake at 375°F for 20 to 30 minutes until the biscuits are beautifully golden and the filling bubbles. I recommend checking at 15 minutes and rotating the pan to ensure even baking; if the biscuits are browning too quickly, tent with foil.

Step 6: Finish with Butter and Serve

Once out of the oven, brush the tops of the biscuits with the remaining melted butter for that irresistible shiny, buttery finish. Let it cool a few minutes — that filling is hot! Then dig in, preferably with loved ones nearby.

How to Serve Chicken Pot Pie Casserole Recipe

Garnishes

I usually keep it simple with fresh chopped parsley or thyme sprinkled right on top for a pop of bright color and an herbal note. Sometimes a quick dusting of freshly cracked pepper jazzes it up just right. If I’m feeling indulgent, a little shredded cheddar on the biscuits before baking is heavenly.

Side Dishes

This casserole is pretty hearty, so I like pairing it with a crisp green salad or some roasted broccoli for contrast. A light vinaigrette or tangy slaw cuts through the richness perfectly. For a Sunday dinner vibe, steamed green beans or a simple cucumber salad complete the meal beautifully.

Creative Ways to Present

For special occasions, I’ve served this in individual ramekins topped with a single biscuit for a charming, personalized touch. Another favorite is sprinkling extra herbs and a bit of grated Parmesan over the biscuit tops before baking — it adds a gourmet spin that guests love. Using decorative biscuit cutters also gives a fun shape to the topping, making it festive for holidays.

Make Ahead and Storage

Storing Leftovers

I usually cover leftover casserole tightly with foil or plastic wrap and keep it in the fridge for up to 3 days. The flavors actually deepen overnight, and reheating in the oven helps maintain the biscuit topping’s texture much better than the microwave.

Freezing

Freezing works well if you store the filling and biscuit topping separately. I freeze the filling in airtight containers and biscuits in their original packaging or wrapped tightly. When ready, thaw both in the fridge overnight, then assemble and bake fresh for best results. This keeps the biscuits from getting soggy.

Reheating

Reheat leftovers in a 350°F oven covered loosely with foil for about 20 minutes, removing the foil toward the end to crisp up the biscuits. This way, you get that freshly baked texture back instead of ending up with a chewy or soggy topping.
