Recipe Tips

- How to keep chicken from drying out: Use the low setting and avoid overcooking. Check doneness at the 5-hour mark.
- Best store-bought pesto to use: Choose a high-quality refrigerated or jarred pesto with visible basil and pine nuts.
- When to add cheese for best melt: Add mozzarella in the last 15 minutes to ensure it melts perfectly without getting rubbery.
