Warm the pot: Heat 1–2 tablespoons olive oil in a large pot over medium heat until shimmering.
Sauté aromatics: Add onion, carrots, and celery.
Season with a pinch of salt. Cook 5–6 minutes, stirring, until the onions soften and look glossy.
Add garlic and herbs: Stir in the garlic, dried thyme (or Italian seasoning), and the bay leaf. Cook 30–60 seconds until fragrant.
Add chicken: Stir in the chicken pieces and a pinch of pepper.
Cook 2–3 minutes, just to take the raw edge off. You don’t need full browning.
Pour in broth: Add the chicken broth. If using potatoes, add them now.
Bring to a gentle boil, then reduce to a steady simmer.
Simmer: Cook 12–15 minutes, or until the chicken is cooked through and the potatoes (if using) are tender.
Veggie add-ins: Add zucchini or green beans, if using. Simmer another 5 minutes until tender but still bright.
Add greens: Stir in spinach or kale. Cook 1–2 minutes, just until wilted.
Remove the bay leaf.
Finish and season: Add 1–2 teaspoons lemon zest and 1–2 tablespoons lemon juice. Stir in fresh parsley or dill. Taste and adjust salt and pepper.
Serve: Ladle into bowls and serve hot.
A slice of crusty bread or a sprinkle of grated Parmesan is a nice touch.
