How to Make Chicken, Leek and Butternut Squash Bake
Step 1: Prepare the Chicken
Start by cutting those boneless chicken thighs into bite-sized pieces. This helps them cook evenly and soak up all the herbs. Heat your pan with a little low calorie spray, then toss in the chicken with thyme, parsley, and seasoning. Cook until they get a lovely golden glow and set them aside. This initial sear is key to locking in those juicy flavors that will make your Chicken, Leek and Butternut Squash Bake unforgettable.
Step 2: Sauté the Vegetables
In the same pan, melt your butter and add the sliced onion, diced butternut squash, and a sprinkle of paprika. Cook gently until the squash starts to soften—this is when it releases that subtly sweet aroma. Gradually splash in some chicken stock to prevent sticking and lift all those delightful browned bits from the pan’s base—this magic adds depth and richness to every mouthful.
Step 3: Add Leeks and Garlic
Next, stir in the sliced leeks and minced garlic. Let them cook gently for about 5 to 8 minutes. This step softens the leeks until they’re silky and golden, while the garlic infuses the whole dish with savory warmth. At this point, your kitchen will smell absolutely irresistible, setting the perfect scene for the next steps.
Step 4: Transfer and Assemble
Now, spread the cooked vegetables evenly in an ovenproof dish—be sure not to crowd them, so everything bakes evenly. Layer the golden chicken pieces on top and pour over any juices you collected on the plate. Drizzle the rest of the chicken stock over everything and finish with a generous sprinkle of freshly grated parmesan. Cover with foil to keep the moisture in as it bakes.
Step 5: Bake to Perfection
Bake the covered dish in a preheated oven at 180°C fan (or 200°C conventional, 400°F, gas mark 6) for 15 minutes. Then remove the foil to allow the top to brown and bake for another 15 minutes until the chicken is cooked through, and the butternut squash is tender. The parmesan should have formed a golden, bubbling crust that adds a delightful texture contrast in this Chicken, Leek and Butternut Squash Bake.
How to Serve Chicken, Leek and Butternut Squash Bake

Garnishes
A sprinkle of fresh parsley right before serving adds a lovely pop of green and a bright herbal note that really freshens up this rich dish. You can also consider a light drizzle of extra virgin olive oil or a few shavings of parmesan for an elegant touch.
Side Dishes
This Chicken, Leek and Butternut Squash Bake stands wonderfully on its own, but pairing it with a crisp green salad or steamed seasonal vegetables like broccoli or green beans provides a vibrant balance. For something heartier, buttery mashed potatoes or crusty bread work beautifully to soak up every bit of that delicious sauce.
Creative Ways to Present
For a more rustic vibe, serve this bake in individual ramekins or small casserole dishes, which makes it feel special and perfect for cozy dinners. Alternatively, turning leftovers into a warm lunch by topping the bake with a poached egg or dollop of crème fraîche adds exciting new dimensions to the flavors.
Make Ahead and Storage
Storing Leftovers
Leftover Chicken, Leek and Butternut Squash Bake keeps very well in an airtight container in the fridge for up to three days. Simply ensure it cools completely before sealing to maintain freshness and prevent sogginess.
Freezing
This bake freezes beautifully, making it a fantastic meal prep option. Portion into freezer-safe containers and freeze for up to two months. To best preserve taste and texture, thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers gently in the oven at 160°C (320°F) for about 20 minutes, or until warmed through, to keep the chicken tender and the butternut squash creamy. Microwaving works in a pinch but may slightly soften the crispy parmesan topping.
FAQs
Can I use chicken breasts instead of thighs?
Absolutely! Chicken breasts will work fine but keep in mind they tend to be leaner and can dry out faster, so watch the cooking time closely to maintain juiciness in your Chicken, Leek and Butternut Squash Bake.
What can I substitute if I don’t have leeks?
If leeks aren’t handy, mild onions or scallions make good substitutes, providing a similar sweet onion flavor that blends beautifully with the butternut squash and chicken.
Is this dish suitable for a low-carb diet?
While butternut squash is a starchy vegetable, the overall dish is still relatively balanced and can fit into a moderate low-carb plan if you control portion sizes or reduce the squash amount slightly.
Can I make this vegan?
Yes! Swap the chicken for hearty mushrooms or tofu, use vegetable stock instead of chicken stock, and replace parmesan with a vegan-friendly alternative or nutritional yeast for that cheesy punch.
What’s the best way to peel and dice butternut squash?
Use a sturdy vegetable peeler to remove the skin, then carefully cut the squash into manageable chunks, removing seeds before dicing into even cubes to ensure they cook uniformly in the bake.

Instructions
- Preheat the Oven: Set your oven to 180°C fan (200°C conventional), 400°F, or Gas Mark 6 to prepare for baking.
- Prepare the Chicken: Cut the chicken thighs into thirds for smaller pieces. Heat a large frying pan over medium-high heat and spray it with low calorie spray.
