Easy Sheet Pan Chicken and Pierogies with Buttered Onions Step-by-step instructions

Before you start

Before you begin, ensure your workspace is clear and your oven is fully preheated to 400°F (200°C). Remove the pierogies from the freezer just before assembly to prevent them from thawing prematurely, which can lead to a mushy texture.

Have your baking sheet lined with parchment paper and your ingredients measured and ready to go. Proper preparation ensures that the assembly process is swift and the ingredients hit the oven at the ideal temperature for roasting.

Instructions

Preparation and Slicing

1. 1Prepare the Ingredients
   Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper to ensure easy cleanup. Cut the chicken breast into uniform one-inch chunks and slice the onion into thin half-moons. Ensure the chicken is handled safely by washing your hands thoroughly after contact with raw poultry.
   Look for Chicken pieces should be roughly the same size to ensure even cooking.
   Tip Keep the chicken chilled in the refrigerator until the very last moment before arranging on the pan.

The chicken is cut into uniform pieces and the onions are sliced thinly, ready for the pan. The oven is preheated, and the baking sheet is lined with parchment paper.

Assembly and Seasoning

2. 2Assemble the Sheet Pan
   Arrange the pierogies, chicken chunks, and onion slices in a single layer across the parchment-lined baking sheet. Drizzle the melted garlic butter evenly over the ingredients. Sprinkle the chopped fresh dill and black pepper over the top to season everything uniformly. Place the pan into the preheated oven carefully.
   Look for Ingredients should be spread out without overlapping to allow for proper browning and roasting.
   Tip Using a light-colored parchment paper helps monitor the browning of the onions and pierogies.

The pierogies, chicken, and onions are carefully arranged in a single layer. The garlic butter is drizzled evenly, and the dill and pepper are sprinkled across for flavor, ensuring everything is ready for the oven.

Roasting to Perfection

3. 3Roast and Serve
   Bake the sheet pan for 20 to 25 minutes. The dish is finished when the pierogies have golden, crispy edges and the chicken reaches an internal temperature of 165°F (74°C). Remove the pan from the oven and allow the chicken to rest for at least 5 minutes before serving to ensure the juices redistribute.
   Look for The chicken should be opaque white throughout with no pink, and the onions should be soft and tender.
   Safe temperature 165°F (74°C) internal temperature (poultry)
   Tip Check the internal temperature of the thickest chicken chunk using a meat thermometer to guarantee safety.

The meal is roasted until the pierogies are golden and the chicken is fully cooked through. The kitchen smells of toasted garlic and savory, roasted onions, indicating the dish is ready to be served.

Common mistakes

Avoid overcrowding the baking sheet, as this will cause the ingredients to steam rather than roast, resulting in soggy pierogies.

Ensure the chicken pieces are cut to a uniform size; if some pieces are significantly smaller than others, they may overcook while the larger pieces remain underdone.

Additionally, do not skip the 5-minute resting period, as this is essential for the chicken to remain juicy and tender after being exposed to the high heat of the oven.

How to tell it’s done

The dish is considered done when the chicken reaches a safe internal temperature of 165°F (74°C). You can verify this by inserting a meat thermometer into the thickest piece of chicken.

Visually, the pierogies should exhibit a distinct golden-brown color on their edges, and the onions should be translucent and soft, showing signs of slight caramelization. The chicken should be opaque and firm to the touch, not rubbery or pink.
