How to Make Roasted Chicken with Leek and Butternut Squash Bake Recipe
Step 1: Prepare and Sear the Chicken
Begin by cutting your boneless, skinless chicken thighs into thirds. This size helps them brown evenly and cook thoroughly in the bake. Heat a pan over medium-high heat and lightly spray with low-calorie oil to keep things light. Season the chicken pieces generously with dried parsley, thyme, salt, and black pepper, giving them that flavorful hero status. Sear the chicken until each piece develops a beautiful golden crust, locking in the juices and adding layers of roasted flavor. Once browned, set the chicken aside to rest while you prepare the veggies.
Step 2: Cook the Vegetables with Butter and Spices
In the same pan, introduce a tablespoon of salted butter, or olive oil if you prefer, letting it melt and fill the kitchen with warmth. Add the sliced yellow onion and diced butternut squash, sprinkling the paprika over to infuse a smoky undertone and a splash of rich color that is visually delightful. Cook until the squash just begins to soften and the onions become translucent, stirring occasionally so those flavors meld and the pan picks up those delicious browned bits left from the chicken.
Step 3: Add Broth, Leeks, and Garlic
Gradually pour in the chicken broth to deglaze the pan, scraping up those caramelized morsels for an extra punch of savory goodness. Stir in the sliced leeks and minced garlic, allowing them to cook together with the squash and onions for about 5 to 8 minutes. By this point, the butternut squash should be tender but not mushy, and the leeks softened just enough to melt into everything else, creating a comforting vegetable medley that is bursting with flavor and texture.
Step 4: Assemble and Bake
Transfer the vegetable mixture into a single layer in a baking dish, creating a vibrant bed of squash, leeks, and onions. Nestle the seared chicken pieces on top and pour in any accumulated pan juices for moist, succulent bites. Sprinkle the freshly grated parmesan cheese evenly over the entire dish, its nutty saltiness promising a golden, crispy crust as it bakes. Cover the dish with foil to gently steam everything together and bake in a preheated oven at 180 °C fan / 200 °C / 400 °F for 15 minutes.
Step 5: Finish Baking Until Golden and Cooked Through
After 15 minutes, remove the foil to allow the parmesan topping to brown beautifully and the chicken skin to crisp just right. Continue baking for another 15 minutes to ensure the chicken is thoroughly cooked and the veggies are tender. Once done, give everything a final seasoning check with salt and pepper, garnish with freshly chopped parsley, and prepare to serve a dish bursting with warmth, flavor, and pure comfort.
How to Serve Roasted Chicken with Leek and Butternut Squash Bake Recipe

Garnishes
A sprinkle of fresh parsley is a simple yet brilliant way to add a pop of color and a fresh herbal note that brightens every bite. For a little extra indulgence, you might consider some thin lemon zest curls or a light drizzle of high-quality olive oil to bring out all the roasted flavors further.
Side Dishes
The natural richness of this bake pairs wonderfully with crisp green salads or steamed green beans tossed in a hint of garlic and lemon. For those wanting extra carbs, a side of crusty bread or creamy mashed potatoes balances the texture beautifully and turns the meal into a full, satisfying feast.
Creative Ways to Present
Try serving individual portions in small oven-safe ramekins for a stunning presentation that elevates the experience. You can also layer the bake in a shallow serving dish for buffets or family-style dinners, allowing everyone to help themselves to the irresistible mix of chicken and veggies with that irresistible golden parmesan crust.
Make Ahead and Storage
Storing Leftovers
Once cooled, place leftover Roasted Chicken with Leek and Butternut Squash Bake Recipe into airtight containers. Stored properly in the refrigerator, it will keep wonderfully for up to 3 days while maintaining its flavors and textures.
Freezing
This bake also freezes very well. For best results, freeze in individual portions or in a freezer-safe dish, tightly covered with foil and plastic wrap, and use within 2 months. Be sure to thaw overnight in the refrigerator before reheating.
Reheating
Reheat leftovers gently in a preheated oven at 175 °C / 350 °F, covered with foil to prevent drying out, until warmed through—usually about 15-20 minutes depending on portion size. Alternatively, microwaving on a medium setting works for a quick meal, just be mindful to cover to retain moisture.
FAQs
Can I use chicken breasts instead of thighs?
Absolutely! While thighs stay juicier, chicken breasts can be used if you prefer. Just be careful not to overcook them, as they tend to dry out faster. Slicing breasts into smaller pieces helps them cook evenly alongside the veggies.
Is it possible to make this dish vegetarian?
Yes! Swap the chicken with hearty roasted chickpeas or tofu, and use vegetable broth instead of chicken broth. Adding some smoked paprika or liquid smoke can add depth for a satisfying vegetarian bake.
Can I prepare the dish entirely ahead of time?
Indeed, you can assemble the dish up to the baking stage and refrigerate it for several hours before cooking. Just allow the bake to come back to room temperature for about 20 minutes before placing it in the oven to ensure even cooking.
What can I substitute for parmesan cheese?
If parmesan is not available, a hard cheese with a similar salty, nutty flavor like Grana Padano or Pecorino Romano works well. For a dairy-free option, nutritional yeast sprinkled on top gives a cheesy flavor without the dairy.
Can I use frozen leeks and squash?
While fresh is best for texture, frozen leeks and butternut squash can be used in a pinch. Thaw and drain them well to avoid excess moisture, which could make the bake watery, and reduce the amount of broth slightly.
Final Thoughts
There is something truly special about the Roasted Chicken with Leek and Butternut Squash Bake Recipe that makes it a standout meal any time of the year. Its blend of simple ingredients transformed into a harmonious, flavorful dish will bring joy to your table and your taste buds.

Instructions
- Preheat the oven: Set your oven to 180 °C fan / 200 °C / 400 °F to prepare for baking the casserole later.
- Prepare the chicken: Cut the chicken thighs into thirds for even cooking and better presentation. Heat a pan over medium-high heat with a low-calorie oil spray to prevent sticking.
- Sear the chicken: Season the chicken pieces with dried parsley, thyme, salt, and black pepper. Sear them in the hot pan until they develop a light golden crust. Remove and set aside to keep warm.
- Sauté vegetables: In the same pan, melt the butter. Add the sliced onion, diced butternut squash, and paprika, cooking until the squash begins to soften, stirring occasionally to prevent burning.
