Ingredients You’ll Need

The ingredients for this Chicken, Leek and Butternut Squash Bake Recipe come together to create layers of flavor and texture. Each element plays a key role, from the tender chicken thighs to the subtly sweet butternut squash and aromatics like leeks and garlic. When shopping, pick fresh leeks and a firm butternut squash for the best results.

Chicken thighs: I prefer boneless, skinless for ease, and cutting them into smaller pieces helps them cook evenly and stay juicy.
Dried parsley and thyme: These herbs add a gentle earthiness that pairs beautifully with the chicken and veggies.
Salt and black pepper: Simple seasonings that enhance the natural flavors—don’t be shy here.
Salted butter (or olive oil): Butter adds richness but olive oil works if you want a lighter touch.
Onion: Halved and sliced for sweetness and depth; yellow or white onions both work well.
Butternut squash: Peeled and cubed; its creamy texture and natural sweetness are essential.
Paprika: I use smoked paprika sometimes for a subtle smoky note, but sweet paprika works fine too.
Leeks: Key ingredient! Make sure they’re well washed to avoid grit and sliced thinly.
Garlic: Minced or crushed, this adds warmth and aroma to the dish.
Chicken stock: Using a good quality stock like Better Than Bouillon makes a difference in flavor.
Parmesan cheese: Freshly grated parmesan on top gives a lovely golden crust and a salty, nutty kick.
Fresh parsley: Chopped and sprinkled at the end for a fresh, herbaceous finish.
Low calorie spray: A handy way to keep the cooking light without sticking.

Variations

I love tweaking this Chicken, Leek and Butternut Squash Bake Recipe depending on what’s in my fridge or my mood. It’s a recipe that really welcomes personalization, so don’t hesitate to swap ingredients or add your own spin to it.

Add some heat: Sometimes I add a pinch of chili flakes or a dash of cayenne to the paprika for a gentle kick—perfect if you like a bit of spice.
Swap the cheese: If you’re not a fan of parmesan, crumbled feta or grated gruyere also work well to add that golden topped finish.
Make it dairy free: Just use olive oil instead of butter and skip the cheese, or try a sprinkle of nutritional yeast for that cheesy flavor.
Vegetarian version: Replace the chicken with extra butternut squash, mushrooms, or even chickpeas for a hearty plant-based roast that still feels satisfying.
Seasonal changes: You can swap the butternut squash for sweet potatoes or carrots if that’s what you have on hand—same cozy comfort vibes.

How to Make Chicken, Leek and Butternut Squash Bake Recipe

Step 1: Prep and Sauté the Chicken

Start by preheating your oven to 180°C fan (or 400°F/gas mark 6). While it heats, cut your chicken thighs into bite-sized pieces—this helps them cook through evenly and quickly. Heat a large frying pan over medium-high heat and spray it lightly with the low-calorie spray. Toss in the chicken along with a teaspoon of dried parsley, half a teaspoon of thyme, and a generous pinch of salt and black pepper. Fry until the chicken pieces are just golden. Don’t overcook here, as they’ll finish cooking in the oven. Once golden, remove them and set aside—this step locks in the flavor early on.

Step 2: Cook the Vegetables with Flavor

In the same pan, melt a tablespoon of butter (or olive oil if you prefer). Add the sliced onion, cubed butternut squash, and sprinkle over a teaspoon of paprika. Let the veggies cook down gently, stirring now and then. The butternut squash should soften a bit but not completely mushy—this way it finishes perfectly in the oven. To prevent sticking and scrape up those tasty brown bits off the pan, gradually add small splashes of chicken stock as you stir—this deglazing step adds so much flavor and helps everything cook evenly.

Step 3: Add Leeks and Garlic

Next, add the sliced leeks and the minced garlic to the pan. Cook everything together for another 5 to 8 minutes, stirring gently. You want the leeks soft and a bit golden, and the squash tender but holding shape. This mixture will be the delicious base for your bake, so take your time here and enjoy those wonderful aromas filling your kitchen.

Step 4: Assemble and Bake

Now, transfer the vegetable mixture into a large ovenproof dish, spreading it out in an even layer. Arrange the browned chicken pieces on top, and don’t forget to drizzle any juices left on your plate back over everything—they’re packed with flavor. Pour over the remaining chicken stock and sprinkle the entire bake generously with freshly grated parmesan cheese. Cover the dish tightly with foil and pop it into the oven for 15 minutes.

After 15 minutes, take off the foil and bake for another 15 minutes uncovered. This second bake crisps up the parmesan topping beautifully, turning it golden and slightly crunchy. It also ensures that the chicken and butternut squash are fully cooked and succulent inside.

Garnishes

I love to finish this bake with a sprinkle of fresh parsley right before serving—that bright pop of green really freshens up the dish and balances the rich flavors. Sometimes, a grating of extra parmesan or a squeeze of lemon juice can also elevate it beautifully.

Side Dishes

This bake feels like a complete meal in itself, but I often serve it alongside a simple mixed green salad dressed lightly with lemon and olive oil for brightness. Roasted garlic bread or crusty sourdough also pairs wonderfully, soaking up every bit of those tasty juices.

Creative Ways to Present

For special occasions, I’ve tried serving individual portions in small ramekins for a charming presentation, which guests always appreciate. Another fun way is layering the bake in a clear glass casserole dish so everyone can see those beautiful layers of veggies, chicken, and golden cheese — it’s as nice to look at as it is to eat!

Make Ahead and Storage

Storing Leftovers

Leftovers from this Chicken, Leek and Butternut Squash Bake Recipe store beautifully in the fridge for up to 3 days. I usually let it cool completely, then transfer to an airtight container—this keeps the flavors intact and stops it from drying out.

Freezing

If I make a bigger batch, freezing is a lifesaver. Just cool the bake fully, portion it out, and pop it into freezer-safe containers or bags. It freezes well for up to 2 months and defrosts overnight in the fridge before reheating.

Reheating

To reheat, I usually cover the bake with foil and warm it in the oven at 160°C (320°F) until heated through—this keeps the dish moist and preserves that lovely golden topping. You can also microwave leftovers but I find the oven does a better job at reviving the texture.

FAQs

Can I use chicken breast instead of thighs in this bake?

Absolutely! Chicken breast will work fine, but keep in mind it can dry out more easily than thighs, so I recommend cutting it into larger chunks and watching the cooking time closely to avoid overcooking.
Do I need to peel the butternut squash for this recipe?

Yes, peeling is best for a tender, melt-in-your-mouth texture. The skin is quite tough and won’t soften well in the bake, though you can roast it separately if you’d like to use the peel in a different dish.
Can I make this recipe dairy-free?

Definitely! Swap the butter for olive oil and omit the parmesan or use a dairy-free cheese alternative. You could also sprinkle some nutritional yeast for that cheesy flavor without the dairy.
How do I know when the bake is fully cooked?

The chicken should be cooked through and no longer pink inside, and the butternut squash should be tender when pierced with a fork. The cheese on top should be golden and slightly crispy to signal it’s ready.
Can I prepare this recipe ahead and bake it later?

Yes, you can assemble the dish up to the baking step, cover it tightly, and refrigerate for up to 24 hours before baking. Just add a few extra minutes to the baking time if starting cold from the fridge.
