This hearty chicken and butternut squash bake brings together tender chicken thighs, sweet butternut squash, and savory leeks in a beautiful marriage of flavors.

• Uses everyday ingredients that transform into something special
• Perfect for meal prep – it actually tastes better the next day
• Easily adaptable to what you have in your pantry or fridge

The Key Players

Chicken Thighs
Dark meat chicken thighs remain juicy and tender throughout the baking process. The higher fat content compared to breast meat means more flavor, and they won’t dry out as easily. If you prefer chicken breasts, that works too – just reduce the cooking time slightly.

Butternut Squash
The star of the show with its sweet, nutty flavor that becomes even more pronounced when roasted. Don’t stress if you’re not a pro at peeling and cutting butternut squash – many supermarkets now sell it pre-cut to save time.

Leeks
These add a gentle onion flavor that’s milder than regular onions. Make sure to wash them thoroughly as they can hide dirt between their layers. If you can’t find leeks, substitute with spring onions or extra regular onion.

Parmesan
The cheese forms a beautiful crust on top while adding a salty, umami depth. Freshly grated works best, but pre-grated will do in a pinch.

Make It Your Own

Mediterranean Twist

Swap the dried herbs for oregano and rosemary, add some chopped bell peppers with the vegetables, and sprinkle with crumbled feta instead of Parmesan for a Mediterranean-inspired version.

Spicy Kick

Add a diced jalapeño or a teaspoon of red pepper flakes when cooking the vegetables. Finish with a sprinkle of smoked paprika before serving for a dish with some heat.

Vegetarian Option

Skip the chicken entirely and double the butternut squash. Add a can of drained, rinsed chickpeas when assembling the bake for protein, and use vegetable stock instead of chicken stock.

Let’s Get Cooking

Step 1: Prep and Season the Chicken

The key here is not to overcook the chicken at this stage – you’re just looking for a light golden color to seal in the juices and develop flavor. The chicken will finish cooking in the oven.

Step 2: Create the Vegetable Base

As the butternut squash cooks, it will begin to caramelize slightly, which enhances its natural sweetness. This contrasts beautifully with the savory elements in the dish. The small additions of stock while cooking help prevent sticking and create a delicious base.

Step 3: Layer and Bake

Layering is important here – the vegetables form a bed that keeps the chicken moist as everything bakes together. The initial covered bake allows all the flavors to meld without drying out, while the uncovered portion creates that irresistible golden top.

Kitchen Wisdom

• Don’t rush the vegetable cooking stage – properly softened vegetables will release more flavor into the final dish
• For extra flavor, marinate the chicken pieces in the herbs, salt, and pepper for 30 minutes before cooking
• If your butternut squash is particularly hard to cut, poke a few holes in it and microwave for 2-3 minutes to soften it slightly
• Save Parmesan rinds in your freezer and add one to the stock for an extra depth of flavor
• For a creamier finish, stir in 2 tablespoons of crème fraîche or cream cheese just before adding the Parmesan

Serving Suggestions

This bake is substantial enough to serve on its own, but pairs beautifully with a simple green salad dressed with a light vinaigrette to cut through the richness. For a heartier meal, serve alongside some crusty bread to soak up the delicious juices or with a side of steamed green beans.

A glass of unoaked Chardonnay or a light Pinot Noir complements the flavors nicely if you’re enjoying this as a dinner with friends.

Storing and Reheating

This dish actually improves with time, making it perfect for meal prep. Store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of stock or water to prevent it from drying out, and warm in a 350°F (175°C) oven until heated through, about 15-20 minutes.

You can also freeze portions for up to 2 months. Thaw overnight in the refrigerator before reheating.

Common Questions

Can I use sweet potato instead of butternut squash?

Absolutely! Sweet potato makes an excellent substitute and cooks in about the same amount of time. The flavor profile will be slightly different but equally delicious.

My family doesn’t like leeks. What can I use instead?

No problem – substitute with an extra onion or try some sliced fennel for a different but complementary flavor profile.

Can I make this ahead for a dinner party?

Yes! Prepare the dish up to the point of baking, cover, and refrigerate for up to 24 hours. When ready to serve, allow it to come to room temperature for 30 minutes, then bake as directed, perhaps adding an extra 5 minutes to the covered baking time.

Is there a dairy-free option?

Replace the butter with olive oil and either skip the Parmesan or use a dairy-free alternative. Nutritional yeast can provide a similar savory note without the dairy.
