Poached Chicken with Tomatoes, Olives, and Green Beans

This elegant poached chicken with tomatoes, olives, and green beans is a bright and healthy dish that celebrates fresh, Mediterranean flavours. Poaching the chicken in a fragrant stock ensures the breast meat stays exceptionally succulent and tender, while the vibrant topping provides a punchy contrast. The combination of sun-ripened tomatoes and briny Kalamata olives creates a natural dressing that pairs perfectly with the lean protein, making it a sophisticated yet simple choice for a nutritious midweek meal.

As a high-protein option, this recipe is ideal for those seeking a lighter dinner that doesn't compromise on taste. The inclusion of crisp-tender haricots verts adds a lovely textural element and provides a boost of fibre and vitamins. It is a wonderful gluten-free and low-carb dish that tastes equally good served warm or at room temperature, making any leftovers perfect for a gourmet lunch the following day.

Ingredients for Poached Chicken with Tomatoes, Olives, and Green Beans

  • 4 skinless boneless chicken breast halves (800g total)

  • 1 tablespoon plus 1/4 teaspoons kosher salt

  • 1200ml water

  • 425ml low-sodium chicken broth (425ml )

  • 1 fresh thyme sprig

  • 350g haricots verts or other thin green beans, trimmed

  • 80ml extra-virgin olive oil

  • 120ml brine-cured green and black olives such as picholine and Kalamata, pitted and chopped

  • 1 tablespoon torn fresh oregano leaves

  • 1/8 teaspoons black pepper

Sprinkle chicken all over with 1 tablespoon salt and let stand.

While chicken is standing, bring water, broth, and thyme to a boil in a 4- to 6-quart heavy pot, then add beans and cook, uncovered, until crisp-tender, 3 to 6 minutes. Transfer beans with a slotted spoon to a bowl and toss with 1 tablespoon oil and salt and pepper to taste.

Add salted chicken to broth and cook at a bare simmer, uncovered, 6 minutes. Remove pot from heat and let stand, covered, until chicken is cooked through, about 15 minutes .

Transfer chicken with tongs to a cutting board and cool, about 5 minutes.

While chicken is cooling, stir together tomatoes, olives, oregano, pepper, and remaining 1/4 teaspoons salt and 60ml oil in a bowl.

Holding a knife at a 45-degree angle, cut chicken across the grain into 1-inch-thick slices.

Divide green beans among 4 plates, then arrange sliced chicken over beans and top with tomato olive mixture.
