Step 1
Start by placing the chicken breasts in your slow cooker. In a separate bowl, whisk together the Dijon mustard, chopped onion, lemon juice, maple syrup, olive oil, teriyaki sauce, soy sauce, minced garlic, and rosemary until everything is well combined. Pour this flavorful mixture over the chicken, making sure the sauce covers the pieces evenly. Cover the slow cooker and cook on high for about 1 to 2 hours, or until the chicken is cooked through and no longer pink in the center. Once done, give it a gentle stir to coat the chicken in the sauce before serving.
