Step‑by‑Step Instructions for Chicken Leek & Butternut Bake
Step 1: Preheat and Prepare
Begin by preheating your oven to 200°C (400°F) while greasing a large ovenproof dish with a little butter. This will ensure that nothing sticks as your delicious Chicken Leek & Butternut Bake cooks to golden perfection. Have your ingredients ready and your workspace tidy for a smooth cooking experience.
Step 2: Sear the Chicken
Cut the boneless skinless chicken thighs into thirds, then season them generously with salt, pepper, and paprika. In a large skillet, melt butter over medium-high heat and sear the chicken pieces until they are golden brown, about 3-4 minutes per side. Once seared, remove them from the skillet and set aside to let the juices settle.
Step 3: Sauté the Onions
In the same skillet, add more butter if needed, and toss in the chopped yellow onion. Sauté over medium heat until the onions turn translucent, about 4-5 minutes. This process builds a flavorful base for the layers in your Chicken Leek & Butternut Bake, as sweet aromas fill your kitchen.
Step 4: Add the Vegetables
Now, add the 1-inch cubed butternut squash and the paprika to the sautéed onions. Cook for about 5 minutes, stirring occasionally, until the squash starts to soften and caramelize. This will infuse your bake with sweetness and texture, enhancing the overall dish.
Step 5: Deglaze and Incorporate
Pour in the chicken broth to deglaze the skillet, scraping up any tasty browned bits stuck to the bottom. Add in the clean, chopped leeks and minced garlic, cooking until the leeks are tender, about 4-5 minutes. These flavors will meld beautifully, creating a savory foundation for your Chicken Leek & Butternut Bake.
Step 6: Assemble the Bake
Transfer the sautéed mixture of vegetables into your prepared baking dish, spreading it evenly. Nestle the seared chicken pieces on top of the veggies, ensuring they’re well placed for even cooking. Pour the remaining chicken broth over everything to keep it moist during baking.
Step 7: Cover and Bake
Cover the dish tightly with aluminum foil to lock in moisture and place it in the preheated oven. Bake for 15 minutes, allowing the flavors to meld and the chicken to cook through, making your home smell delightful.
Step 8: Add Cheese and Finish Baking
After the initial bake, carefully remove the foil and sprinkle freshly grated Parmesan cheese over the top. Return the uncovered dish to the oven and bake for an additional 15 minutes, or until the chicken is golden brown and the internal temperature reads 165°F. This creates a deliciously cheesy crust that complements the hearty dish perfectly.
Step 9: Cool and Garnish
Once out of the oven, allow the Chicken Leek & Butternut Bake to cool slightly as you adjust seasonings if needed. Garnish with freshly chopped parsley for a splash of color and freshness before serving. This final touch elevates the dish, making it not only flavorful but visually appealing as well.
