Step‑by‑Step Instructions for Chicken Leek and Butternut Squash Bake

Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (fan) / 200°C / 400°F. This will ensure the oven reaches the ideal temperature before you add your casserole. A well-heated oven is essential for evenly cooking your Chicken Leek and Butternut Squash Bake, helping to achieve that golden, crispy topping.

Step 2: Prepare the Chicken
While the oven heats up, cut the chicken thighs into thirds and season them generously with salt, pepper, chopped parsley, and thyme. This step infuses the chicken with flavor that will shine through the bake. Set the seasoned chicken aside while you prepare the vegetables, ensuring they remain flavorful and ready for cooking.

Step 3: Sear the Chicken
In a large skillet, heat a splash of olive oil over medium-high heat. Once hot, carefully add the seasoned chicken pieces. Sear them for about 4-5 minutes, until they are golden brown on the outside, but not fully cooked through. Remove the chicken from the skillet and set it aside on a plate while you sauté the vegetables.

Step 4: Sauté the Butternut Squash
Using the same skillet, add the diced butternut squash and chopped onion to the pan. Sauté for 5-7 minutes until they are softened and beginning to caramelize slightly. Deglaze the pan by pouring in a splash of chicken stock, scraping up any brown bits from the bottom. This adds wonderful flavor to the vegetables and sets the stage for your Chicken Leek and Butternut Squash Bake.

Step 5: Add the Leeks and Garlic
Next, add the sliced leeks and minced garlic to the skillet with the squash and onion. Continue cooking for another 5 minutes, stirring often, until the leeks are tender and aromatic. This combination of vegetables will create a savory base for the Chicken Leek and Butternut Squash Bake, ensuring each bite is bursting with flavor.

Step 6: Assemble the Bake
In a large baking dish, layer the sautéed vegetable mixture evenly across the bottom. Then, nestle the golden chicken pieces on top. Pour the remaining chicken stock over the layers, allowing the flavors to meld together during baking. This dish is designed to be comforting and hearty, so ensure everything is distributed for a well-rounded Chicken Leek and Butternut Squash Bake.

Step 7: Add Cheese and Bake
Sprinkle a generous layer of grated Parmesan cheese over the assembled bake. Cover the baking dish tightly with foil to trap in moisture. Place it in the preheated oven and bake for 15 minutes, allowing the flavors to infuse. After this initial baking time, carefully remove the foil and bake for an additional 15 minutes, or until the cheese is golden and bubbling, indicating it’s ready to enjoy.

Step 8: Serve and Garnish
Once your Chicken Leek and Butternut Squash Bake is out of the oven, let it sit for a few minutes before serving. Garnish with fresh parsley to add a pop of color and freshness. This beautiful dish showcases the wholesome ingredients beautifully, ensuring your meal is as delightful to look at as it is to eat.
