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 ensures a perfectly roasted finish for your Roasted Chicken Leek and Butternut Squash Bake. While the oven warms up, prepare your baking dish by lightly spraying it with low-calorie oil, allowing for easy cleanup later.
Step 2: Prepare the Chicken
Next, cut the boneless skinless chicken thighs into thirds and season them generously with salt, ground black pepper, dried parsley, and thyme. In a hot frying pan, sear the chicken pieces for about 5-7 minutes until they’re golden brown. This step enhances the flavor of the chicken, ensuring a juicy outcome in your bake.
Step 3: Sauté the Vegetables
In the same pan, melt a tablespoon of salted butter or olive oil over medium heat. Add the yellow onion, diced butternut squash, and paprika, stirring frequently for about 5 minutes. Cook until the squash starts to soften and the onion becomes translucent, releasing a wonderful aroma that fills your kitchen.
Step 4: Deglaze and Add Aromatics
Gradually pour in the chicken broth while scraping the bottom of the pan to deglaze, about 1–2 minutes. Once combined, add the chopped leeks and minced garlic, cooking for another 3-4 minutes until the leeks are golden and tender. This mixture will create a flavorful bed for the chicken in your bake.
Step 5: Assemble the Bake
Carefully transfer the vegetable mixture to a large ovenproof dish and spread it out evenly. Nestle the seared chicken pieces on top of the vegetables, then pour any remaining broth over everything to keep it moist while baking. This layering helps the flavors meld beautifully during cooking.
Step 6: Baking Time
Sprinkle freshly grated Parmesan cheese evenly over the top of the dish. Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 15 minutes, then remove the foil and bake for an additional 15 minutes until the chicken is cooked through and the top is golden brown and bubbly.
Step 7: Final Touches
Optionally, broil the bake for 2-3 minutes to achieve an extra crispy, browned top. Keep a close eye to prevent burning. Once finished, take it out of the oven and let it sit for a few minutes before garnishing with fresh parsley leaves. This adds a vibrant touch and freshness to your Roasted Chicken Leek and Butternut Squash Bake.
Step 8: Serve and Enjoy
Carefully serve your comforting bake straight from the dish, savoring the warm, hearty flavors. This delightful one-pan meal not only looks inviting but also promises to be a crowd-pleaser, perfect for family gatherings or cozy weeknight dinners.

Expert Tips for Roasted Chicken Leek and Butternut Squash Bake
Uniform Squash Prep: Ensure that your butternut squash is cubed uniformly to facilitate even cooking alongside the chicken and leeks.
Avoid Overcrowding: Don’t overcrowd the baking dish. This can lead to steaming instead of that desirable browning on your roasted chicken and vegetables.
Sear Chicken First: Browning the chicken thighs before adding them to the bake enhances flavor and prevents a rubbery texture in your Roasted Chicken Leek and Butternut Squash Bake.
Check Temperature: Always use a meat thermometer. Make sure the chicken reaches an internal temperature of 165°F for safe consumption.
Fresh Ingredients: Whenever possible, use fresh herbs like parsley and thyme. They elevate the flavor profile significantly over dried ones.
Customize Your Bake: Feel free to incorporate your favorite root vegetables or adjust the seasonings according to your family’s taste preferences for a more personalized dish.
Make Ahead Options

Roasted Chicken Leek and Butternut Squash Bake Recipe FAQs
How do I choose ripe butternut squash?
Absolutely! When selecting butternut squash, look for a firm, heavy squash with a tan color and a matte finish. Avoid any squash with dark spots or soft spots, as these may indicate overripeness or decay. The skin should be smooth, and the stem intact. For the best flavor, choose a squash that feels heavy for its size.
What’s the best way to store leftovers from the bake?
Very! After you’ve enjoyed your Roasted Chicken Leek and Butternut Squash Bake, let it cool completely, then transfer leftovers to an airtight container. In the fridge, they can last up to 4 days. The flavors actually deepen and improve with time, making your next meal even more delicious!
Can I freeze this dish for later?
Absolutely! To freeze your Roasted Chicken Leek and Butternut Squash Bake, first, let it cool completely. Portion it into freezer-safe containers or freezer bags, and label with the date. It can stay in the freezer for up to 3 months. When you’re ready to enjoy it again, thaw overnight in the refrigerator, then reheat in the oven at 180°C (350°F) for about 20-25 minutes, or until heated through.
How can I avoid the chicken turning rubbery?
Very! To prevent rubbery chicken in your bake, sear the chicken thighs in the pan before adding them to the dish. This step not only adds flavor but also locks in moisture. Also, ensure the cooking temperature is just right; chicken should reach an internal temperature of 165°F for a juicy, tender bite.
What if I have dietary restrictions regarding allergies?
Absolutely! If you’re dealing with dietary allergies, you can easily customize this bake. If you’re allergic to dairy, omit the parmesan or use a dairy-free alternative. For gluten sensitivities, this recipe is naturally gluten-free, but always check the chicken broth you use. If you have other restrictions, feel free to substitute vegetables or proteins that work for you; the versatility of this dish is what makes it a family favorite!
How does the cooking process change if I use bone-in chicken thighs?
Absolutely! If you decide to use bone-in chicken thighs instead of boneless, keep in mind that the cooking time will increase. You should brown the chicken for about 8-10 minutes instead of 5-7 minutes. When it comes to baking, extend the time by an additional 10-15 minutes until the chicken reaches 165°F internally. This allows the flavors to fully develop while still ensuring juicy, tender meat.
