Chicken Leek & Butternut Bake Ingredients

For the Bake

Boneless Skinless Chicken Thighs – The heart of this dish, providing juiciness; use thawed and patted dry for the best flavor.
Yellow Onion – A key flavor-builder through caramelization; opt for a sweet onion for a milder taste.
Butternut Squash – Adds natural sweetness and texture; cut into 1-inch cubes for even roasting.
Leeks – Offers a gentle onion flavor; make sure they are cleaned thoroughly before cooking.
Garlic – Enhances flavor tremendously; crushed cloves can give a deeper taste than chopped.
Chicken Broth – Essential for moisture and depth; consider using Better Than Bouillon for added richness.

For Seasoning

Dried Parsley and Thyme – Aromatic seasonings that elevate the dish; fresh herbs give a vibrant flavor boost.
Paprika – Introduces a mild smokiness; cayenne can be swapped for those who enjoy heat.
Salt and Ground Black Pepper – Key for flavor enhancement; adjust seasoning to your preference.

For Cooking

Salted Butter – Perfect for browning the chicken and sautéing veggies; olive oil is a great alternative for a lighter option.
Freshly Grated Parmesan Cheese – Adds a creamy finish; top it towards the end of baking to prevent burning.
Fresh Parsley – A lovely touch for garnishing, adding freshness and color before serving.

Step‑by‑Step Instructions for Chicken Leek & Butternut Bake

Step 1: Preheat the Oven
Begin by preheating your oven to 200°C (400°F). While the oven warms up, generously grease a large ovenproof dish with butter or olive oil to prevent sticking. This step is essential to ensure that your Chicken Leek & Butternut Bake will have a beautiful, golden finish as it cooks.

Step 2: Sear the Chicken
Cut the boneless skinless chicken thighs into thirds, then season with salt and pepper. In a large skillet, melt salted butter over medium-high heat, then add the chicken pieces. Sear them for about 3-4 minutes on each side until they turn golden brown. Once browned, remove the chicken and set it aside on a plate as you prepare the vegetables.

Step 3: Sauté the Vegetables
In the same skillet, add diced yellow onion and sauté until it becomes translucent, which should take about 3-4 minutes. Next, add the cubed butternut squash and sprinkle in paprika. Cook everything together for another 5 minutes, stirring occasionally. The vegetables should be slightly tender, allowing their natural sweetness to shine through.

Step 4: Add the Aromatics
To the skillet with the vegetables, pour in some chicken broth to deglaze, scraping up any flavorful bits from the bottom. Add the cleaned and sliced leeks along with minced garlic. Cook for an additional 4-5 minutes, until the leeks are tender and fragrant, enhancing the delicious aroma of your Chicken Leek & Butternut Bake.

Step 5: Assemble the Bake
Spread the sautéed vegetable mix evenly in the greased ovenproof dish. Then, nestle the seared chicken pieces on top of the veggies. Pour any remaining chicken broth over the dish to ensure the bake stays moist while cooking. This layering is key to achieving a flavorful Chicken Leek & Butternut Bake.

Step 6: Bake Covered
Cover the dish tightly with aluminum foil and place it in the preheated oven. Let it bake for 15 minutes—this creates steam, helping the chicken to stay juicy and the flavors to meld beautifully together. As it bakes, the cozy aroma will begin to fill your kitchen.

Step 7: Bake Uncovered
After 15 minutes, carefully remove the foil. Sprinkle freshly grated Parmesan cheese on top of the bake for that creamy, mouthwatering finish. Bake uncovered for an additional 15 minutes, until the chicken reaches an internal temperature of 165°F and the vegetables are tender and vibrant in color.

Step 8: Final Touches
Once cooked, take the Chicken Leek & Butternut Bake out of the oven and let it cool briefly. Taste and adjust the seasonings with extra salt or pepper if needed. Finally, garnish with fresh parsley for a pop of color and freshness before serving, making your comforting dish even more inviting.

Make Ahead Options

These Hearty Roasted Chicken Leek and Butternut Squash Bake is an absolute delight for meal prep enthusiasts! You can chop the vegetables and season the chicken up to 24 hours in advance, storing them separately in airtight containers in the refrigerator to maintain freshness and prevent browning. Additionally, you can assemble the entire dish without baking and cover it tightly, storing it in the fridge for up to 3 days. When you’re ready to enjoy this comforting dish, simply preheat the oven and bake it directly from the fridge, adding an extra 5-10 minutes to the cooking time to ensure everything is heated through. You’ll have a warm, nourishing meal ready to serve with minimal effort!

Chicken Leek & Butternut Bake Variations

Creamy Upgrade: Stir in cream cheese or sour cream for a rich, creamy texture. This makes the bake even more indulgent and delightful for those cozy nights.
Veggie Variety: Toss in chopped spinach or kale for an added nutritional boost. It’s a sneaky way to pack in those greens without compromising taste.
Cheesy Delight: Swap out Parmesan for mozzarella and cheddar for a gooey, melty topping. The combination of these cheeses creates an irresistible crust that will leave everyone wanting more.
Zesty Finish: Drizzle fresh lemon juice or sprinkle zest before serving for a bright, zesty lift. A touch of citrus elevates the dish, adding depth and balance to every bite.

When selecting butternut squash, look for a squash with a tan rind free from dark spots and blemishes. It should feel heavy for its size and have a firm skin.
