Step 1: Season the Chicken - Start by laying your chicken breasts out on a plate or cutting board. Sprinkle both sides evenly with salt, pepper, and garlic powder. Take a moment to really coat them well. This simple seasoning step builds the base layer of flavor, and it is worth doing right. It might not seem like much, but it makes a difference in every bite.
Step 2: Sear for Flavor - Heat the oil in a large skillet over medium high heat. Once it is hot, add the chicken breasts carefully. You should hear a nice sizzle when they hit the pan. Let them cook for about two to three minutes on each side until they develop a light golden color. You are not cooking them through here, just giving them a bit of color and locking in those juices.
Step 3: Transfer to Slow Cooker - Place the seared chicken breasts into the bottom of your slow cooker in an even layer. Try not to stack them too much so they cook evenly. At this point, the kitchen already smells pretty good, and you are just getting started.
Step 4: Mix the Sauce - In a medium bowl, whisk together the apricot preserves, brown sugar, chicken broth, soy sauce, and Dijon mustard. Keep whisking until the mixture is smooth and well combined. This sauce is where all the magic happens, balancing sweet and savory in a way that just works.
Step 5: Pour and Cover - Pour the sauce evenly over the chicken in the slow cooker. Make sure everything gets coated. Put the lid on and set it to low for four to six hours or high for three to four hours. Now you can walk away and let it do its thing while you handle the rest of your day.
Step 6: Finish and Serve - Once the chicken is cooked through and tender, spoon the sauce over the top before serving. You can leave the chicken whole or shred it depending on what you prefer. If you want the sauce thicker, remove the lid for the last twenty to thirty minutes so it reduces slightly. Serve it warm and watch it disappear.
