Gluten Free Chicken Pot Pie Casserole Recipe

This creamy, golden Gluten Free Chicken Pot Pie Casserole is made with tender shredded chicken, mixed vegetables, and a fluffy drop-biscuit topping, ready in just 50 minutes. The savory sauce bubbles up through the crust as it bakes to perfection. I make this whenever I need serious comfort food without the gluten.

Why This Classic Works

I used to struggle with rolling out gluten-free pie crusts because they would crack and crumble instantly, turning dinner into a stressful project. Switching to a drop-biscuit casserole style solved that problem completely while keeping the flavors intact. You get all the buttery, flaky goodness without ever needing a rolling pin.

The ratio of sauce to biscuit is crucial here so the topping doesn’t get soggy underneath. I learned that letting the filling thicken nicely on the stove first guarantees a perfect consistency every time.

Gluten Free Chicken Pot Pie Casserole Ingredients

For the Filling:

• 1/4 cup unsalted butter
• 1 small yellow onion, diced
• 2 stalks celery, sliced
• 1/3 cup gluten-free all-purpose flour (measure-for-measure blend)
• 2 cups chicken broth
• 1/2 cup heavy cream
• 3 cups cooked chicken, shredded or cubed
• 2 cups frozen mixed vegetables (peas, carrots, corn), thawed
• 1 tsp dried thyme
• 1/2 tsp salt
• 1/4 tsp black pepper

For the Biscuit Topping:

• 1 1/2 cups gluten-free all-purpose flour
• 2 tsp baking powder
• 1/2 tsp garlic powder
• 1/2 cup cold unsalted butter, cubed
• 3/4 cup whole milk
• 1 large egg (optional, for egg wash)

How To Make Gluten Free Chicken Pot Pie Casserole

1. Prepare Base: Preheat your oven to 400°F (200°C). Melt the butter in a large skillet over medium heat and sauté the onion and celery until softened, about 5 minutes.
2. Thicken Sauce: Whisk in the gluten-free flour and cook for 1 minute, then slowly pour in the chicken broth and heavy cream while whisking constantly until smooth and slightly thickened.
3. Combine Filling: Stir in the shredded chicken, thawed mixed vegetables, thyme, salt, and pepper, then pour the mixture into a greased 9×13 baking dish.
4. Make Topping: In a medium bowl, whisk together the flour, baking powder, and garlic powder, then cut in the cold butter with a fork or pastry cutter until the mixture resembles coarse crumbs.
5. Form Biscuits: Stir the milk into the flour mixture just until a soft dough forms, being careful not to overwork it.
6. Bake: Drop spoonfuls of the biscuit dough evenly over the chicken filling and bake for 25-30 minutes until the biscuits are golden brown and the filling is bubbling.

Recipe Tips

• Check your blend: Ensure your gluten-free flour blend contains xanthan gum; if it doesn’t, add 1/2 teaspoon to the biscuit dry ingredients to prevent them from crumbling.
• Don’t overmix: Stir the biscuit batter just until the dry ingredients are moistened to keep the topping tender and fluffy rather than dense.
• Broil for color: Gluten-free baked goods sometimes don’t brown as deeply as wheat versions, so pop the dish under the broiler for the last 2 minutes if you want a darker crust.

What To Serve With Chicken Pot Pie Casserole

Serve this rich casserole with a crisp green salad tossed in a vinaigrette to cut through the creamy sauce. Roasted green beans or asparagus also make excellent sides that add freshness without competing with the main dish flavors.

How To Store

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover the dish with foil and warm it in a 350°F oven for 15-20 minutes to crisp up the biscuits, or microwave individual portions for a softer texture.

FAQs

Can I use raw chicken for this recipe?
No, this recipe requires pre-cooked chicken. You can quickly poach chicken breasts, use leftover roasted chicken, or shred a store-bought rotisserie chicken to save time.

Can I make this dairy-free?
Yes, simply substitute the butter for a plant-based stick butter and use unsweetened almond or oat milk in place of the cream and milk.

Why is my filling too runny?
The filling will thicken as it cools, but if it seems too thin coming out of the oven, ensure you let the roux (butter and flour) bubble for a minute before adding liquid next time.
