How to Make Slow Cooker BBQ Chicken

1. Prepare the Slow Cooker

Lightly coat a 5- to 6-quart slow cooker with cooking spray or a small amount of oil to help prevent sticking.

2. Add the Chicken and Peppers

Place the cubed chicken breast into the slow cooker. Add the diced red and green bell peppers evenly over the chicken.

3. Add the BBQ Sauce

Pour the barbecue sauce over the chicken and peppers, spreading it as evenly as possible.

4. Slow Cook

Cover and cook on LOW for 3 to 4 hours or HIGH for 1 ½ to 2 ½ hours, until the chicken reaches an internal temperature of 165°F (74°C).

5. Stir and Rest

Stir everything together so the chicken and peppers are coated in the barbecue sauce. Let the mixture rest for about 5 minutes before serving.

6. Serve

Spoon the BBQ chicken over cooked rice, noodles, quinoa, or mashed potatoes. You can also serve it in warm tortillas or lettuce cups.

What to Serve with BBQ Chicken

Turn this easy slow cooker chicken into a complete meal by pairing it with:

• Steamed white or brown rice
• Buttered egg noodles
• Mashed potatoes
• Quinoa
• Corn on the cob
• Roasted broccoli
• Green salad
• Black beans
• Steamed green beans
• Sliced avocado
• Warm tortillas

For a lighter option, serve the chicken over cauliflower rice or inside crisp lettuce cups with a squeeze of fresh lime.

Easy Variations

Use Different BBQ Sauces

Try honey barbecue sauce for a sweeter flavor or smoky barbecue sauce for a deeper, more robust taste.

Add a Little Spice

For extra flavor, add a small amount of crushed red pepper flakes or diced jalapeño along with the bell peppers.

Change the Vegetables

Yellow or orange bell peppers work beautifully in this recipe. You can also add other quick-cooking vegetables according to what you have available.

Try Chicken Thighs

Boneless, skinless chicken thighs can replace the chicken breast. They provide a richer flavor and tend to remain juicy during longer cooking.

Make BBQ Chicken Bowls

For an easy meal-prep lunch, divide the cooked chicken between containers and add rice, corn, black beans, and green vegetables.

Tips for Tender Slow Cooker Chicken

Don’t overcook the chicken. Chicken breast is lean and can become dry if left in the slow cooker longer than necessary.

Check the temperature. The safest way to determine doneness is to use an instant-read thermometer and make sure the thickest pieces reach 165°F (74°C).

Cut the chicken evenly. Similar-sized pieces cook more consistently.

Choose a flavorful BBQ sauce. Since barbecue sauce provides most of the seasoning in this simple recipe, use one you already enjoy.

Don’t skip the resting time. A few minutes after cooking allows the sauce and juices to settle before serving.

Meal Prep and Storage

This slow cooker BBQ chicken is convenient for meal prep because it reheats easily. Allow leftovers to cool promptly, then refrigerate them in a covered container.

Reheat individual portions until heated through and serve with freshly cooked rice, vegetables, or your favorite side dish.
