Step‑by‑Step Instructions for Roasted Chicken Leek and Butternut Squash Bake
Step 1: Preheat Your Oven
Start by preheating your oven to 180°C fan (200°C/400°F/Gas Mark 6). This will ensure that your Roasted Chicken Leek and Butternut Squash Bake cooks evenly and develops a beautiful golden-brown crust. While the oven heats, gather your ingredients and prepare your cooking space for a smooth preparation process.
Step 2: Prepare the Chicken
Take boneless skinless chicken thighs and cut them into thirds for even cooking. In a large skillet over medium-high heat, add a touch of oil or butter and sear the chicken pieces until they’re golden on the outside, about 4–5 minutes per side. Once cooked, transfer the chicken to a plate and set aside, allowing the flavorful drippings to remain in the pan.
Step 3: Sauté the Vegetables
In the same skillet with drippings, melt 2 tablespoons of salted butter over medium heat. Add diced yellow onion and butternut squash, seasoned with paprika, and sauté for about 6–8 minutes, until the onion is translucent and the squash begins to soften. The squash should be tender enough to pierce with a fork, creating a delightful aroma in your kitchen.
Step 4: Deglaze and Add More Flavor
Next, gradually pour in chicken broth to deglaze the pan, scraping up any flavorful bits stuck to the bottom. Stir in the chopped leeks and garlic, cooking for an additional 3–4 minutes until the leeks are tender. This step builds a rich base for your Roasted Chicken Leek and Butternut Squash Bake, infusing the dish with savory flavors.
Step 5: Assemble the Bake
Transfer the vegetable mixture into a large ovenproof dish, spreading it out evenly. Layer the seared chicken thighs on top, then pour the remaining chicken broth over everything. Finish by generously sprinkling freshly grated Parmesan cheese, allowing it to create a delicious crust while baking. This layering ensures every bite is packed with flavor.
Step 6: Bake to Perfection
Cover the dish with foil and place it in the preheated oven. Bake for 15 minutes, then remove the foil and continue baking for an additional 15 minutes. This will allow the chicken to reach a safe internal temperature of 165°F (75°C) and achieve that coveted golden top. Your kitchen will fill with the mouthwatering scent of Roasted Chicken Leek and Butternut Squash Bake.
Step 7: Serve and Garnish
Once baked, take the dish out of the oven and let it rest for a few minutes. Season with additional salt and pepper to taste, if desired. Garnish with fresh parsley leaves for a pop of color and flavor before serving. Your cozy Roasted Chicken Leek and Butternut Squash Bake is now ready to bring warmth and delight to your table!

Roasted Chicken Leek and Butternut Squash Bake Recipe FAQs
How do I choose the right butternut squash?
Absolutely! Look for butternut squash that is dark tan and firm to the touch, with no soft spots or blemishes. Ideally, it should feel heavy for its size. If you see any dark spots all over or it feels excessively soft, it’s best to choose another one!

Store any leftovers in an airtight container in the fridge for up to 4 days. The flavors actually deepen over time, so you might find it tastes even better the next day! If you’d like to keep it longer, you can freeze portions in airtight containers for up to 3 months.
What are the best thawing methods for frozen leftovers?
The best way to thaw your frozen Roasted Chicken Leek and Butternut Squash Bake is to transfer it to the refrigerator and let it thaw overnight. This slow method preserves texture and flavor.

What should I do if my chicken isn’t browning properly?
No worries! If your chicken isn’t browning, it might be because the pan wasn’t hot enough. Make sure to preheat your pan properly. Add the chicken in a single layer to avoid overcrowding, and give it time—about 4–5 minutes per side should develop a beautifully golden crust!
Can you suggest substitutions for the chicken if I want a vegetarian option?
Very! For a vegetarian version, you can replace the chicken with hearty vegetables or plant-based alternatives like tofu or tempeh. You might want to increase the amount of butternut squash or add other veggies like mushrooms or chickpeas for added protein and texture.
