Using a rotisserie chicken or leftover holiday turkey, make a creamy keto chicken pot pie casserole filled with your favorite veggies and topped with an easy-to-make buttery drop biscuits instead of traditional pie crust.

This keto chicken pot pie casserole recipe is a twist on the classic pot pie, perfect for using up leftover holiday turkey from Thanksgiving or a rotisserie chicken. A wooden spoon holds a serving of chicken pot pie casserole. The pot pie filling is a rich, creamy mixture of sautéed celery, fresh green beans, carrots, yellow onion and mushrooms; although, you can use any vegetables in your fridge that have seen better days or even toss in some of your holiday leftovers like stuffing or green bean casserole. Arrowroot powder, chicken broth and cream cheese create a thicken and savory sauce that coats our veggie and chicken chunks. Instead of messing with pie dough, keep your rolling pin stored away and top the chicken pot pie mixture with keto drop biscuits instead of flaky pie crust. These buttery almond flour based drop biscuits are easier to prepare since all the ingredients are combined in one bowl and dropped on top of the chicken mixture before baking to form golden, puffy biscuit dollops.

Alternatives to keto biscuits

Instead of this drop biscuit recipe, you can try using these keto alternatives:
  • Pie crust – Just roll out flaky pie crust and top the casserole with a layer of pie dough to bake.
  • Rolls – Similar to my pizza casserole recipe, top the pot pie with those buttery parmesan rolls.
  • Croutons – Make a batch of keto croutons by toasting chunks of bread tossed in melted butter in the oven until lightly toasted and golden brown.
  • Breadcrumbs – Make an easy batch of homemade breadcrumbs and sprinkle on top the chicken pot pie.
  • Crackers – Break up crackers into small pieces or pulverize. Then sprinkle on top the keto casserole before baking.

Storage information

To store this low-carb casserole, let it cool to room temperature first. Then cover with plastic wrap or foil, or transfer to an airtight container. Store in the refrigerator for up to 4 days.  You can freeze the pot pie casserole. Wrap the cooled casserole with plastic wrap or place in a freezer-safe container. Freeze up to 3 months. To reheat, thaw in the refrigerator overnight then bake until heated through. The texture of the biscuit may change after freezing.

Frequently Asked Questions

Can I use other vegetables in this recipe?

Yes, you can use other low-carb vegetables in your keto chicken pot pie casserole. From broccoli, zucchini, cauliflower and bell pepper, you can add different veggie into the pot pie mixture.

Can I spread the biscuit mixture on top the casserole instead of dropping the biscuit dough?

Yes, you don't have to drop the biscuit dough on top of the casserole. If you want every inch of pot pie covered with buttery breading, then spread the dough all over the top.

The oat fiber is added for texture and substance. You might be able to get away with omitting it but will should add more almond flour - perhaps 1/2 cup more almond flour.
