Before you start

Begin by thoroughly washing and drying the baby potatoes and green beans. Trim the ends of the green beans and slice the potatoes into uniform halves. Slice the chicken breasts horizontally into thin, even fillets, then pat them dry with paper towels to ensure a good sear.

Measure out the butter, finely mince the garlic, and chop the fresh herbs. Keep the raw chicken refrigerated while preparing the vegetables, bringing it out no more than thirty minutes before cooking.

Ingredients at a glance (7)
  • 1 1/2 lb baby potatoes, halved
  • 1 lb green beans, trimmed
  • 1 1/2 lb boneless, skinless chicken breasts, sliced into thin fillets
  • 6 tbsp unsalted butter, divided
  • 4 cloves garlic, minced
  • 2 tbsp fresh herbs, chopped
  • 1 tbsp seasoning blend, divided

Instructions

Roasting the Vegetables

  1. Roast the Potatoes and Green Beans
    Preheat the oven to 400°F (200°C). Toss the halved baby potatoes with two tablespoons of melted butter and half of the seasoning blend. Spread them in a single layer on a baking sheet and roast for 20 minutes. Add the trimmed green beans to the sheet, toss to combine, and roast for an additional 10 minutes until the potatoes are golden and tender.
    Look for The potatoes should be golden brown and the green beans tender-crisp.
    Tip Spread the potatoes out completely to avoid steaming them.

The baby potatoes should be deeply golden brown and crispy on the edges, while remaining fork-tender in the center. A fragrant, earthy aroma of roasted potatoes will fill the kitchen.

Check that the skins are slightly wrinkled and caramelized before removing them from the oven. The green beans should be vibrant green and tender-crisp, showing slight blister marks from the high heat.

Searing the Chicken

  1. Sear the Chicken Fillets
    Season the chicken breast fillets evenly with the remaining seasoning blend. Melt two tablespoons of the butter in a large skillet over medium-high heat. Add the chicken fillets to the hot skillet and sear for 5 to 6 minutes per side, using tongs to turn them, until a deep golden-brown crust forms on both sides.
    Look for A rich, golden crust should form on the chicken surface.
    Tip Avoid moving the chicken around constantly to allow a proper crust to develop.

The chicken fillets will develop a beautiful, deep golden-brown crust on both sides, and the pan will be filled with sizzling, aromatic juices. When pressed lightly with tongs, the meat should feel firm yet springy. The savory scent of toasted spices and seared poultry indicates that the chicken is fully cooked and ready for the butter sauce.

Finishing with Garlic Butter

  1. Melt the Garlic Butter
    Reduce the heat to medium. Add the remaining butter and minced garlic directly to the skillet with the chicken. Let the butter melt and bubble, spooning the melted garlic butter repeatedly over the chicken fillets for about 2 minutes to lock in moisture, until the garlic is highly fragrant and the chicken reaches a safe internal temperature of 165°F (74°C).
    Look for The butter should bubble vigorously and the garlic should be fragrant without burning.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Keep the heat at medium to prevent the butter and garlic from scorching.
  2. Combine and Garnish
    Transfer the roasted potatoes and green beans into the skillet with the chicken, or arrange everything together in a warm glass baking dish. Toss gently to coat the vegetables in the bubbling garlic butter and savory pan juices. Garnish with the fresh herbs right before serving.
    Look for The vegetables should be thoroughly coated in the glossy garlic butter sauce.
    Tip Serve immediately while hot to enjoy the best texture.

The garlic butter sauce should be bubbling vigorously, releasing an intense, mouthwatering aroma of toasted garlic and fresh herbs. The melted butter will cascade over the chicken and vegetables, coating them in a glossy, golden glaze. The garlic should be soft and fragrant, without any signs of burning or darkening beyond a light golden hue.

Common mistakes

One common mistake is crowding the pan when searing the chicken, which causes the meat to steam in its own moisture rather than developing a golden-brown crust. Cook the chicken in batches if necessary to maintain high pan temperatures.

Another error is adding the garlic too early in the process; garlic burns easily under high heat, which imparts a bitter, unpleasant flavor to the entire dish. Always add the garlic during the final minutes of cooking, reducing the heat slightly to gently cook it.

How to tell it’s done

To determine if the chicken is cooked through, insert an instant-read digital food thermometer into the thickest part of the largest fillet. It must register a safe internal temperature of 165°F (74°C).

The juices should run completely clear, and the meat should no longer show any pink coloration when sliced. For the potatoes, a sharp fork should slide easily into the center of the largest piece without resistance, confirming they are perfectly tender.
