Step 1: Prepare the Base
Place the chicken breasts in the bottom of your Crockpot. Add the diced potatoes, onions, and frozen vegetables on top.
Step 2: Add the Creamy Sauce
In a separate bowl, whisk together the cream of chicken soup, chicken broth, garlic powder, thyme, salt, and pepper. Pour this mixture evenly over the chicken and vegetables in the slow cooker.
Step 3: Cook on Low and Slow
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours. The chicken should be tender and easy to shred.
Step 4: Shred and Mix
Once cooked, remove the chicken, shred it using two forks, and return it to the pot. Stir in the heavy cream (or milk) for that smooth, creamy texture.
Step 5: Add the Biscuit Topping
If you want that golden, flaky finish, preheat your oven to 400°F (200°C). Place the biscuits or puff pastry on a baking sheet and bake until golden brown, about 10–12 minutes.
Step 6: Serve
Spoon the creamy chicken mixture into bowls and top each serving with a warm biscuit or puff pastry square. Brush with melted butter for an extra buttery flavor.
