Can I use frozen chicken breasts in this recipe?

For food safety reasons, it's best to thaw chicken completely before slow cooking. Frozen chicken may spend too long at temperatures that can promote bacterial growth. Thaw your chicken in the refrigerator overnight before adding it to your slow cooker.

How do I know when the chicken is done?

The chicken is done when it reaches an internal temperature of 165°F when tested with a meat thermometer. Another indicator is that it should shred easily with two forks. If it's still tough to pull apart, it needs more time.

Can I double this recipe?

Yes! This recipe doubles well, but you may need to increase the cooking time by 1-2 hours depending on how full your slow cooker is. Make sure your slow cooker isn't more than ¾ full for optimal cooking.

My sauce is too thin – how can I thicken it?

If your sauce is thinner than desired, remove the chicken and set the slow cooker to high with the lid off for about 30 minutes, allowing some liquid to evaporate. Alternatively, mix 1 tablespoon of cornstarch with 1 tablespoon of cold water, stir into the sauce, and cook on high for 15-20 minutes until thickened.

Ketchup: Forms the base of our BBQ sauce, providing tanginess and tomato richness.
Brown sugar: Adds that essential sweetness that balances the acidic ingredients and helps create caramelization.
Worcestershire sauce: Delivers umami depth and complexity that makes homemade BBQ sauce taste authentic.
Red wine vinegar: Brings brightness and tang to cut through the richness of the sauce.
Garlic powder: Infuses the sauce with garlic flavor without the risk of burning that comes with fresh garlic in slow cooking.
Salt: Enhances all the other flavors in the dish.
Crushed red pepper flakes: Adds a gentle heat that balances the sweetness. Adjust to your spice preference.

How to Make Slow Cooker BBQ Chicken

Step 1: Prepare Your Slow Cooker

Place your chicken breasts in a single layer at the bottom of your 4-6 quart slow cooker. Scatter the sliced onion halves over the top of the chicken.

Step 2: Mix the BBQ Sauce

In a mixing bowl, combine ketchup, brown sugar, Worcestershire sauce, red wine vinegar, garlic powder, salt, red pepper flakes, and ground mustard. Stir until everything is well incorporated and the brown sugar has dissolved.

Step 3: Add Sauce to Chicken

Pour your homemade BBQ sauce directly over the chicken and onions, making sure each piece is well coated. Use a spoon to spread the sauce evenly if needed.

Step 4: Cook

Cover your slow cooker with the lid and set to cook. If you’re in a hurry, cook on high for 2-3 hours. For even more tender results, cook on low for 4-5 hours. The chicken is done when it reaches an internal temperature of 165°F and shreds easily with a fork.

Step 5: Finish and Serve

Once cooked, you can either serve the chicken breasts whole with extra sauce spooned over the top, or shred the meat using two forks for BBQ pulled chicken. Stir the shredded chicken back into the sauce before serving.

Pro Tips for Making the Recipe

Don’t Overcook: While slow cookers are forgiving, chicken breasts can dry out if cooked too long. Use a meat thermometer to check for doneness.
Layer Properly: Always place the chicken on the bottom of the slow cooker as it takes the longest to cook.
Sauce Consistency: If you prefer a thicker sauce, remove the lid during the last 30 minutes of cooking to allow some liquid to evaporate.
Size Matters: Try to use chicken breasts that are similar in size so they cook at the same rate.
Boost the Flavor: For deeper flavor, sear the chicken breasts in a hot skillet before adding to the slow cooker.
