Chicken Pot Pie Recipe With Leftover Gravy: Savory Filling Under a Buttery Crust

This recipe transforms yesterday’s meal into today’s masterpiece with a buttery crust that seals in rich, savory goodness. The secret lies in repurposing leftover gravy as the base for an irresistibly creamy filling.

By combining shredded chicken with vegetables and your existing gravy, you create a filling that’s deep in flavor without starting from scratch. The double crust ensures every bite delivers that perfect crisp-to-tender contrast.

What emerges from the oven is a golden, flaky pie with a filling so rich and comforting it tastes like it took hours. The gravy infuses every ingredient with its concentrated savory notes.

Serve hot for the ultimate comfort food experience. This method proves that leftovers can be even better the second time around.

Ingredients for Chicken Pot Pie Recipe with Leftover Gravy

Rich gravy, tender chicken, and flaky crust transform leftovers into comfort food perfection.

The gravy is the heart of this dish. Use a deeply flavored, thick gravy—thin or bland versions won’t deliver the same richness. For the chicken, rotisserie chicken works brilliantly if you don’t have leftovers. I source my pie crusts from Pillsbury (the refrigerated kind) for convenience, but a from-scratch buttery crust elevates this to restaurant quality. Look for crusts with minimal additives for the best texture.

No leftover gravy? Make a quick roux with butter, flour, and chicken broth—it won’t be quite the same but gets the job done. Fresh herbs like rosemary or sage can stand in for thyme. For a richer filling, add a splash of heavy cream (or coconut milk for dairy-free). The mixed veggies can be swapped for fresh—just par-cook them first to avoid a soggy crust.

Assemble and refrigerate unbaked pies for up to 1 day ahead. Baked pies keep in the fridge for 3-4 days or freeze for 3 months. Reheat in the oven to revive the crust’s flakiness—microwaving turns it gummy (don’t do it).

Step-by-Step Instructions for Chicken Pot Pie With Leftover Gravy

Precision in assembly and timing ensures a golden crust with a rich, velvety filling.

Step 1: Prepare the Savory Filling Base

Finely dice the 0.5 whole Yellow Onion and mince the 2 cloves Garlic Cloves. In a large skillet over medium heat, melt 2 tablespoons of the 1 cup Unsalted Butter until foaming subsides. Add the onion and cook for 5-6 minutes until translucent and slightly caramelized.

Stir in the garlic and 1 tsp Fresh Thyme, cooking for 30 seconds until fragrant. This aromatic base builds the depth of flavor that complements the leftover gravy. Avoid browning the garlic—it should smell sweet, not bitter.

Step 2: Thicken and Combine the Filling

Sprinkle the 0.33 cup All-Purpose Flour over the onion mixture, stirring constantly for 1-2 minutes to cook out the raw flour taste. Slowly whisk in the 2 cups Leftover Chicken Gravy and 0.5 cup Chicken Broth, ensuring no lumps form.

Add the 2 cups Cooked Chicken Breast, 1.5 cups Frozen Mixed Vegetables, 0.5 tsp Salt, and 0.5 tsp Black Pepper. Simmer for 8-10 minutes until the mixture thickens enough to coat the back of a spoon and the vegetables are heated through. The filling should be rich but pourable.

Step 3: Assemble the Pot Pie

Preheat your oven to 375°F. Unroll 1 sheet Pie Crust into a 9-inch pie dish, pressing it gently into the bottom and up the sides. Trim any excess dough hanging over the edge. This bottom crust provides structure and prevents sogginess.

Pour the warm filling into the crust, spreading it evenly. Top with the second Pie Crust sheet, crimping the edges with a fork to seal. Cut 4-5 small slits in the center to allow steam to escape during baking.

Step 4: Bake to Golden Perfection

Whisk the 1 whole Large Egg with the 1 tbsp Whole Milk to create an egg wash. Brush it evenly over the top crust, ensuring full coverage for a deep golden finish. This step adds shine and helps the crust brown uniformly.

Bake for 35-40 minutes until the crust is golden brown and the filling bubbles visibly through the slits. If the edges brown too quickly, tent them with foil. Let the pie rest for 10 minutes before serving to allow the filling to set.

Dietary Considerations for This chicken pot pie recipe with leftover gravy

Gluten-Free Adaptation

Swap the pie crust for a gluten-free version—I love Miracle Flour’s blend for a flaky texture. Use cornstarch instead of all-purpose flour to thicken the filling, as it’s naturally gluten-free and works just as well. 💪

Dairy-Free Option

Replace the unsalted butter in the crust with coconut oil or a dairy-free butter alternative like Miyoko’s. For the egg wash, use 1 tbsp almond milk or skip it entirely—the crust will still brown nicely.

Lower-Carb Version

Use a cauliflower crust or skip the top crust entirely for an open-faced pot pie. Thicken the filling with xanthan gum instead of flour—just ¼ tsp does the trick. This cuts carbs without sacrificing richness.

Sodium Considerations

If watching your salt intake, use low-sodium chicken broth and reduce the added salt by half. Taste the gravy first—leftover versions often contain enough salt already. Fresh herbs like thyme add flavor without sodium.

Vegetarian Twist

Replace the chicken with chickpeas or mushrooms for a hearty, meat-free version. Use vegetable broth instead of chicken broth to keep it fully vegetarian. The gravy will still deliver that deep, savory base.

Allergy-Friendly Tips

For nut allergies, ensure your store-bought crust is nut-free. For egg allergies, use a flax egg (1 tbsp ground flax + 3 tbsp water) for the wash. Always check labels on pre-made crusts for hidden allergens. ✨
