Prepare Freezer Bag: Add ingredients directly to freezer bag, laying ingredients in even layer so chicken breasts lay flat, (no mixing required!) and freeze until you’re ready to cook.
To Cook: Determine the appliance you will use to cook this recipe and, once decided, follow the “Instant Pot Instructions” or “Slow Cooker Instructions” as written below.
Instant Pot Instructions: Add frozen ingredients and chicken broth to your Instant Pot insert, set Instant Pot to “Manual” and set the timer for 25 minutes. After cooking, allow the Instant Pot to naturally release pressure. Once you can unscrew the lid of the Instant Pot, it’s fully depressurized. Move on to “Final Steps” as written below.
Slow Cooker Instructions: Thaw ingredients in the refrigerator (this may take upwards of 1 day). Add thawed ingredients and chicken broth to your slow cooker, set to cook for 3 hours on high. Move on to “Final Steps” as written below.
Final Steps: Using tongs or forks, shred chicken. Fold in shredded cheddar and stir until well-combined and cheese has melted. In ¼ tsp increments, add xanthan gum and, using a spoon, fold into sauce until sauce thickens. Serve chicken in bowls and garnish with crumbled bacon and chopped green onion.
