Slow Cooker Mushroom and Vegetable Pot Pie

About the Recipe

This veggie-packed pot pie takes some convenient shortcuts, using sliced mushrooms, mixed frozen vegetables and ready-to-bake biscuits for the topping. 

Serves 6 to 8


  • 1 tablespoon vegan butter
  • 1 (32-ounce) bag frozen vegetable medley (includes carrots, corn, peas, green beans and lima beans), thawed
  • 1 (8-ounce) package sliced baby bella (also called cremini) mushrooms
  • 1 tablespoon finely chopped garlic
  • 1 tablespoon chopped parsley
  • 2 sprigs thyme
  • 1 sprig rosemary
  • 1 teaspoon celery seed
  • 1 teaspoon sea salt
  • 1/2 teaspoon ground black pepper
  • 1 cup unsweetened plain ricemilk
  • 1 cup low-sodium vegetable broth             
  • 2 tablespoons all-purpose flour                    
  • 2 tablespoons cornstarch, if needed for thickening
  • 1 (8-count) can refrigerated ready-to-bake biscuits


Melt butter and pour into the bottom of a slow cooker. Add mixed vegetables, sliced mushrooms, garlic, parsley, thyme, rosemary, celery seed, salt, pepper and ricemilk. In a separate bowl, whisk together broth and flour. Pour over vegetables in the slow cooker and stir to combine everything. Cover and cook on high for 4 hours.

After 4 hours, adjust the racks in your oven so that it can accommodate your slow cooker crock*. Preheat the oven to 350°F. Stir and check the thickness of the sauce. If it’s too thin, spoon out a couple of tablespoons of liquid into a bowl. Whisk cornstarch into hot liquid until dissolved. Add cornstarch mixture back to slow cooker and stir to combine. 

Separate biscuit dough into individual biscuits. Top mixture in slow cooker with biscuits. Bake slow cooker crock, uncovered, 35 to 40 minutes, until biscuits are deep golden brown and cooked through. Let stand 5 minutes before serving.  

*If your slow cooker crock is not removable or is not ovenproof, bake biscuits separately according to package directions. Split biscuits, arrange in bowls and spoon pot pie filling over them.
