Simply put by my husband, “This Chicken Pot Pie Crumble is by far the best chicken pot pie I have ever had!” I agree. The crumble topping is a nice change from using a pie crust. I got the idea from watching “America’s Test Kitchen” and adapted the recipe from there. The crumble topping is what makes it, but if you simply must have a pie crust, you can just use the filling recipe. What makes the filling recipe so good is that you don’t use any “cream of” soups.. In my opinion “cream of” soup ruins a good chicken pot pie!
