Slow Cooker Chicken Alfredo Stew I gave it a 5 with the changes I made. My husband & I love it this way and I have made it 5 times so far I use 2 jars (16 oz) Alfredo pasta sauce 3/4 cup water 1/2 teaspoon dried basil leaves 1/2 teaspoon salt 4 cups cooked diced potatoes with onions (cant find these in the store so cut them up and microwave them for a few minutes just to soften them halfway through) 1 1/2 lb boneless skinless chicken breast, cut into 1-inch-wide strips 1 bag (1 lb) frozen mixed vegetables (California Blend) 1 can of corn And I cook it for 8 hours on low
