Before you start

Before beginning, ensure all produce is thoroughly washed and dried. Have a sharp chef knife and a stable cutting board ready for prep. Measure all seasoning ingredients ahead of time to make the assembly process seamless.

Preheat the oven well in advance to ensure it reaches the necessary temperature for proper roasting, which is critical for achieving golden edges on both the chicken and the potatoes.

Ingredients at a glance (6)
  • 2 lbs boneless skinless chicken breast, sliced
  • 1 lb fresh green beans, trimmed
  • 1 lb baby potatoes, halved
  • 1/4 cup olive oil
  • 4 cloves garlic, minced
  • 2 tbsp fresh herbs, such as rosemary or thyme, chopped

Instructions

Prep and Assembly

  1. Prepare the Ingredients
    Preheat the oven to 400°F (200°C). Wash and slice the chicken breasts into uniform pieces. Trim the ends of the fresh green beans and halve the baby potatoes. Ensure all ingredients are prepped and ready for assembly in the baking dish.
    Look for The oven reaches the target temperature and all vegetables are cleaned and cut.
    Tip Slice the potatoes into even halves to ensure they cook at the same rate as the chicken.

The ingredients should be neatly sliced and trimmed. The garlic and herb oil mixture should be emulsified, and the chicken and vegetables should be evenly arranged in the baking dish, ready to be coated in the flavorful infusion of oil and aromatics.

Seasoning Phase

  1. Season and Assemble
    In a small bowl, whisk together the olive oil, minced garlic, and chopped herbs. Place the chicken, green beans, and potatoes into the large glass baking dish. Pour the garlic herb oil mixture over everything and toss gently with your hands or tongs to ensure every piece is thoroughly coated.
    Look for The oil mixture is evenly distributed and the ingredients are well seasoned.
    Tip Use your hands to ensure the oil and herbs reach every surface of the chicken and vegetables.

Check that the oil is distributed thoroughly across every piece. The green beans should look vibrant, and the potatoes should be lightly coated in the herb mixture.

Ensure no dry spots remain, as this will result in uneven roasting and flavor distribution during the oven stage.

Roasting Completion

  1. Bake and Serve
    Place the baking dish in the preheated oven and bake for 30 to 35 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the potatoes are fork-tender. Remove from the oven and let the dish rest for 5 minutes before serving to allow the juices to redistribute throughout the meat.
    Look for The chicken is golden brown, cooked through to 165°F, and the vegetables are tender.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Avoid overcrowding the dish so the chicken and vegetables roast rather than steam.

The final dish should have deep golden-brown edges on the chicken and crispy, tender potatoes. The aroma of roasted garlic and fresh herbs should be prominent. Verify the internal temperature of the chicken with a thermometer to ensure it is safe and ready to serve.

Common mistakes

A common mistake is overcrowding the baking dish, which causes the ingredients to steam rather than roast. Ensure there is enough space for air to circulate around the chicken and vegetables.

Another error is cutting the potatoes into pieces that are too large, which prevents them from cooking through at the same time as the chicken. Always aim for uniform, bite-sized pieces for the best results.

How to tell it’s done

The chicken is fully cooked when it reaches an internal temperature of 165°F (74°C). Use a meat thermometer inserted into the thickest part of the chicken piece to confirm.

The potatoes should be easily pierced with a fork, indicating they are tender through the center. If the vegetables appear done but the chicken needs more time, cover the dish loosely with foil to prevent over-browning.

  • Poultry: 165°F (74°C) in the thickest part
