Gather your ingredients: chicken breasts, carrots, onion, garlic, herbs, and broth, along with your measuring cups and chopping tools.
Dice the chicken breasts into 1-inch chunks, peel and slice the carrots, dice the onion, and mince the garlic. Arrange everything nearby for easy assembly.
Place the chicken, carrots, onion, and garlic into the slow cooker, spreading them out evenly for balanced cooking.
Pour in the chicken broth, making sure all ingredients are submerged but not overflowing. Add a sprig of fresh herbs or dried herbs crushed for extra flavor.
Cover the slow cooker and set it to low for 6 to 8 hours, or high for 3 to 4 hours, until the chicken is tender and easily shredded, and the vegetables are soft and fragrant.
Once cooked, open the lid and use two forks to shred the chicken directly in the pot, allowing it to soak up the flavorful broth.
Taste the soup and adjust the seasoning with salt and pepper if needed. If you want a heartier dish, add cooked noodles or rice now and let them heat through for about 10 minutes.
Finish by sprinkling chopped fresh parsley or thyme on top for a bright, herbal touch. Serve the soup hot in bowls, garnished with extra herbs if desired.
