This chicken pot pie casserole has been on heavy rotation in our house since last fall, and honestly, I don't see it slowing down anytime soon.
Why This Recipe Works
- A roux-based sauce (butter + flour + milk) creates a silky, thick filling without relying on canned cream-of soups
- Cooking the vegetables until fully softened builds sweetness and depth before the sauce goes in
- Biscuits on top absorb steam from the filling underneath while crisping on the exposed side, giving you both textures in every bite
- Adding frozen peas off the heat keeps them bright green and prevents them from turning mushy
This chicken pot pie casserole has been on heavy rotation in our house since last fall, and honestly, I don't see it slowing down anytime soon. Matt's the one who got me hooked — he kept asking me to make "that chicken pie thing but without the annoying crust" after I spent an entire Sunday wrestling with a from-scratch pie dough that cracked in three places. So I ditched the pie crust entirely, threw some biscuits on top, and now this is the version we actually make.
The beauty of this chicken pot pie casserole recipe is that it's genuinely easy — we're talking a one-skillet filling with a from-scratch cream sauce that takes maybe ten minutes, then you just dump it in a baking dish and drop biscuits on top. No rolling, no crimping, no praying the pastry holds together. The sauce is silky and thick from a simple butter-and-flour roux, with Dijon mustard stirred in for this subtle sharpness that makes the whole thing taste more complex than it has any right to be. Even Ben will eat this, and that kid has rejected every vegetable I've put in front of him for the last six months.
The filling comes together fast — softened vegetables, a quick roux, then milk and broth whisked in until everything goes thick and creamy. Fold in your chicken and peas, transfer to the baking dish, and let the biscuits do their thing in the oven. Twenty-five minutes later you've got bubbling filling and golden, fluffy biscuit tops that are crispy on the outside and soft underneath where they've soaked up all that creamy sauce.
I usually grab a rotisserie chicken on the way home — one bird gives you exactly the four cups of shredded meat you need, and the flavor is honestly better than poaching chicken breasts. This is one of those meals where the leftovers are just as good the next day, which is why I always make the full 13x9 pan even when it's just Matt and me eating it.
Here's how I make it in our kitchen.
How It Comes Together
Chef Tips
- I've found that using a rotisserie chicken is the ultimate shortcut here — one large bird gives you exactly the 4 cups of shredded chicken you need, and the flavor is way better than poaching from scratch on a weeknight.
- Don't skip the Dijon mustard. I was skeptical the first time, but it adds a subtle sharpness that rounds out the creamy filling without tasting mustardy at all.
- After trying both ways, I always use whole milk instead of heavy cream — the filling is plenty rich without it, and the sauce holds together better the next day.
- If you want an even crispier biscuit top, brush each biscuit with a little melted butter before baking.
- This reheats beautifully — I make a full batch on Sunday and Matt and I eat the leftovers for lunch through Wednesday.
Variations
Crescent Roll Crust Version
Press one tube of crescent roll dough into the bottom of the dish, bake 15 minutes, add filling, then top with a second tube and bake 20-30 minutes more for a double-crust casserole.
Turkey Pot Pie Casserole
Swap the chicken for leftover roasted turkey — perfect for using up Thanksgiving leftovers. Everything else stays the same.
Loaded Veggie Version
Skip the chicken and add 2 cups diced potatoes and 1 cup corn along with the peas. Use vegetable broth instead of chicken broth.
Biscuit-From-Scratch Topping
Mix 2 cups flour, 1 tbsp baking powder, ½ tsp salt, and 6 tbsp cold butter. Stir in ¾ cup buttermilk. Drop spoonfuls over the filling before baking.
Serving Suggestions
Serve hot with a simple green side salad or roasted broccoli. It's hearty enough to be a complete meal on its own, but a side of buttered dinner rolls never hurts.
Make It Ahead
Prepare the filling up to 2 days ahead and refrigerate in an airtight container. When ready to bake, transfer the cold filling to the baking dish, top with biscuits, and add 5-8 minutes to the bake time since the filling will be cold.
