Warm the pot: Heat the olive oil in a large, heavy-bottomed pot over medium heat. Add onion, carrots, and celery with a pinch of salt.
Cook 5–7 minutes, stirring occasionally, until the vegetables soften and the onion turns translucent.
Bloom the aromatics: Stir in the garlic, thyme, and parsley. Cook 30–45 seconds until fragrant. Don’t let the garlic brown.
Brown the chicken: Add the chicken pieces, season with salt and pepper, and cook 3–4 minutes, stirring occasionally.
You’re not fully cooking the chicken—just getting a little color for flavor.
Build the broth: Pour in the chicken broth and add the bay leaf. Scrape up any browned bits from the bottom. Bring to a gentle boil.
Add the hearty veg: Stir in the potatoes and green beans.
Reduce heat to a steady simmer and cook 12–15 minutes, until the potatoes are just tender.
Finish with quick-cooking veg: Add the corn and greens. Simmer 3–5 more minutes, until the greens wilt and the chicken is cooked through. If using kale, give it an extra couple of minutes to soften.
Balance and brighten: Remove the bay leaf.
Stir in lemon juice. Taste and adjust with more salt and pepper as needed. If the broth tastes flat, add a splash more lemon or a pinch of salt.
Serve: Ladle into warm bowls and top with chopped fresh parsley or dill.
Add a drizzle of olive oil or a dusting of grated Parmesan if you like.
