Prep the base: Add onion, carrots, celery, garlic, and ginger to the slow cooker.
Drizzle with olive oil and toss to coat. Sprinkle in thyme, oregano, turmeric, salt, and pepper.
Add chicken and liquids: Place chicken on top of the vegetables. Pour in chicken broth and water, and add the bay leaf.
Cook low and slow: Cover and cook on Low for 6–7 hours, or on High for 3–4 hours, until the chicken is very tender and the vegetables are soft.
Shred the chicken: Remove the chicken to a cutting board.
Shred with two forks into bite-size pieces, then return it to the pot. Discard the bay leaf.
Stir in greens: Add spinach, kale, or chard and cook on High for 5–10 minutes, until wilted and bright.
Brighten and balance: Stir in lemon juice. Taste and adjust with more salt, pepper, or lemon as needed.
Optional grains or pasta: For rice or quinoa, stir in cooked grains just before serving.
For pasta, cook it separately until just al dente, then add to bowls and ladle soup over. This keeps the broth clear and prevents mushy textures.
Finish and serve: Ladle into bowls and top with chopped parsley. Serve with extra lemon wedges for a fresh kick.
