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

Step 1: Preheat the Oven
Begin by preheating your oven to 180°C fan (200°C/400°F/Gas Mark 6). This temperature will allow your Roasted Chicken Leek and Butternut Squash Bake to cook evenly and efficiently. While the oven warms, you can prepare the chicken and vegetables, ensuring a smooth cooking process once you start layering the ingredients.

Step 2: Season the Chicken
Take your boneless skinless chicken thighs and cut them into thirds. In a medium bowl, sprinkle the pieces with dried parsley, thyme, salt, and black pepper. Make sure every piece is well-coated with these seasonings as this will greatly enhance the flavors in your Roasted Chicken Leek and Butternut Squash Bake. Set the seasoned chicken aside as you prepare to sear it.

Step 3: Sear the Chicken
Heat a splash of oil or butter in a large frying pan over medium-high heat. Once the pan is hot, add the seasoned chicken pieces and sear them until they are lightly golden—approximately 4-5 minutes. This initial browning adds depth to the flavor of the chicken. Once golden, transfer the chicken to a plate and set aside while you work on the vegetables.

Step 4: Sauté the Vegetables
In the same frying pan, melt 1 tablespoon of salted butter. Add the sliced onion, diced butternut squash, and paprika, stirring occasionally for about 5-7 minutes, or until the squash begins to soften. This step releases the natural sweetness of the vegetables and will form a fantastic base for your Roasted Chicken Leek and Butternut Squash Bake.

Step 5: Add Leeks and Garlic
To the softened vegetable mixture, add the cleaned and sliced leeks along with the chopped garlic. Stir well and sauté for an additional 3-4 minutes until the leeks turn tender, becoming fragrant and translucent. This blend of flavors will amplify the overall taste profile of your dish, making it a family favorite.

Step 6: Layer the Bake
Transfer the sautéed vegetable mixture into a large ovenproof dish. Carefully layer the seared chicken pieces on top of the vegetables, then pour in 1 cup of chicken broth, ensuring everything is moistened. This step is crucial for keeping your Roasted Chicken Leek and Butternut Squash Bake juicy and full of flavor as it bakes.

Step 7: Add Parmesan and Cover
Sprinkle the dish generously with freshly grated parmesan cheese, creating a delicious topping that will melt beautifully. Cover the dish with aluminum foil to trap moisture and enhance cooking. Place it in the preheated oven and bake for 15 minutes, allowing the flavors to meld.

Step 8: Uncover and Continue Baking
After 15 minutes, carefully remove the foil from the dish. Continue baking for an additional 15 minutes, or until the chicken is cooked through and golden on top. You’re looking for an internal temperature of 165°F to ensure your Roasted Chicken Leek and Butternut Squash Bake is safe to enjoy.

Step 9: Final Seasoning and Serve
Once done, take the bake out of the oven and let it rest for a few minutes. Season with additional salt and pepper to taste, then sprinkle fresh parsley over the top for a pop of color. Now, your Roasted Chicken Leek and Butternut Squash Bake is ready to be served, perfect with a side of crusty bread or a fresh salad!

Make Ahead Options

These Roasted Chicken Leek and Butternut Squash Bake provide an ideal solution for busy cooks looking to save time during the week! You can prep the chicken and vegetable layers up to 24 hours in advance by seasoning and layering the ingredients, then covering the baking dish tightly with foil and refrigerating. To maintain flavor and moisture, store the chicken broth separately and add it just before baking. When you’re ready to enjoy, simply preheat the oven and bake as usual, knowing that the depth of flavors has only improved overnight. This way, you’ll have a comforting meal with minimal effort, perfect for those hectic nights!

Expert Tips for Roasted Chicken Leek and Butternut Squash Bake

Use a Thermometer: Check for doneness with an instant-read thermometer—the chicken should reach 165°F before serving.
Experiment with Flavors: Feel free to swap herbs or add different vegetables to keep your Roasted Chicken Leek and Butternut Squash Bake exciting!

Roasted Chicken Leek and Butternut Squash Bake Recipe FAQs

What kind of chicken should I use for this recipe?
Absolutely! I recommend boneless skinless chicken thighs for their tenderness and juiciness during baking. However, if you prefer, you can use chicken breasts, but keep in mind they may dry out more easily, so watch the cooking time carefully.

How should I store leftovers from the bake?
Very easy! Store any leftover Roasted Chicken Leek and Butternut Squash Bake in an airtight container in the fridge for up to 4 days. The flavors actually deepen, making each serving even more delightful!

Can I freeze the leftovers, and what’s the best way to do it?

What if my butternut squash isn’t cooking evenly?
If you find the squash is browning too quickly or not cooking all the way through, it’s likely a matter of size or overcrowding. Make sure to cut the squash into 1-inch cubes for even cooking, and avoid overcrowding the dish to allow for proper roasting instead of steaming.

Is this Roasted Chicken Leek and Butternut Squash Bake suitable for allergies?
When it comes to dietary considerations, be aware that this dish contains chicken, dairy (from the parmesan), and possible allergens from cross-contamination if you’re cooking for someone with severe allergies. Always double-check ingredient labels and consider alternative cheeses or leave out the cheese entirely for a dairy-free version!
