Tips and Variations

  • You can also use different vegetables such as carrots, celery, or zucchini, depending on your preference.

  • If you have time, marinate the chicken overnight for more flavor.

Why Slow-Cooked Chicken Is So Delicious

Slow-cooking chicken is a great way to infuse flavor into the meat. The low heat and long cooking time break down the connective tissue in the chicken, making it tender and juicy. This also allows the flavors from the onions and peppers to seep into the chicken, resulting in a delicious and flavorful dish.

How to Store Leftovers

If you have leftovers, store them in an airtight container in the refrigerator for up to 3-4 days. You can also freeze the leftovers for up to 2 months.

Can I Use Chicken Breasts Instead of Thighs or Drumsticks?

You can use chicken breasts for this recipe, but they won’t be as flavorful or juicy as thighs or drumsticks. If you do use chicken breasts, make sure to sear them for a few minutes on each side before adding them to the roaster pan.

Can I Make This Recipe in a Slow Cooker?

Yes, you can make this recipe in a slow cooker. Simply follow the same instructions but instead of using a roaster pan, transfer the chicken and vegetables to a slow cooker. Cook on low for 6-8 hours or on high for 3-4 hours.

Can I Add Potatoes to This Recipe?

Yes, you can add potatoes to this recipe. Simply cut them into small cubes and add them to the roaster pan with the chicken and vegetables. Make sure to adjust the cooking time accordingly as the potatoes will take longer to cook.
