My go-to comfort dinner has become this fulfilling Chicken, Leek and Butternut Squash Bake. When I want something that's both nourishing and cozy, this dish delivers perfectly. The mix of juicy chicken, caramelized butternut squash, and silky leeks creates a delightful blend that satisfies while still being good for you.
During a hectic week when I needed leftovers, I whipped this up for the first time. It disappeared so fast I had to cook another batch the following evening. Now it's a staple in our house that we make all the time.
Ingredients
- Boneless skinless chicken thighs: they stay moist and tender, adding wonderful richness to the dish
- Butternut squash: brings natural sweetness and turns silky soft after cooking
- Leeks: cook down to a buttery softness with a gentle onion flavor
- Dried herbs: thyme and parsley add wonderful aroma throughout
- Paprika: gives a lovely reddish tint and gentle smoky taste
- Parmesan cheese: forms a tasty golden crust that's utterly mouthwatering
- Chicken stock: keeps everything juicy and ties the flavors together
- Butter: adds depth when cooking the veggies
- Fresh parsley: adds a pop of color and fresh taste at the end
Step-by-Step Instructions
- Prepare the Chicken:
- Slice the chicken thighs into thirds so they cook faster and mix better with other ingredients. Coat them with dried herbs, salt and pepper, then brown them in a hot pan until golden. They'll finish cooking in the oven later, but this step adds tons of flavor.
- Sauté the Vegetables:
- In the same pan, melt some butter to grab all those tasty chicken bits left behind. Toss in onions, butternut squash and paprika, cooking until the squash starts to soften. Pour in a bit of chicken stock to loosen any stuck-on bits from the pan bottom. This makes the base taste amazing.
- Incorporate the Leeks:
- Mix in sliced leeks and garlic with your veggies and cook for about 5-8 minutes. You want the leeks soft and slightly golden while the squash gets tender. Taking your time here lets all the flavors blend together nicely.
- Assemble and Bake:
- Spread your veggie mix evenly in an ovenproof dish. Put the browned chicken pieces on top along with any juices from the chicken. Pour the rest of your stock over everything and sprinkle plenty of Parmesan on top. This way each part cooks just right.
- Final Baking:
- Cover with foil and bake for 15 minutes so the chicken cooks through. Then take the foil off and bake another 15 minutes until it's golden and bubbling. Finish with a sprinkle of fresh parsley and a final taste check for salt and pepper.

The butternut squash really makes this dish special for me. When it roasts, it gets this incredible sweetness and soft texture throughout the casserole. I once made this for my friend who always said she hated butternut squash. After tasting how it soaked up all the chicken flavors, she not only changed her mind but asked for another helping!
Make Ahead Options
You can totally prep this dish ahead of time. Just get everything ready up to the baking part, cover it tight, and keep it in the fridge for up to a day. When you're ready to eat, just add about 10 extra minutes to the first baking time with the foil on. I've found the flavor actually gets even better as it sits, making this perfect for busy nights or when you have guests coming over.
Seasonal Variations
In the summer, try swapping in zucchini or yellow squash instead of butternut squash. They cook a bit faster, so watch your timing. During fall, throwing in a chopped apple adds unexpected sweetness, or use fresh sage in place of dried herbs. When winter comes around, try mixing in parsnips or sweet potatoes with your butternut squash for an even more filling meal.

Serving Suggestions
This dish works great by itself as a complete meal, but goes really well with a simple green salad dressed with just lemon juice and olive oil. For hungrier folks, add some crusty bread to soak up all that tasty sauce, or serve with buttery green beans sprinkled with toasted almonds. It tastes fantastic with a cool glass of Chardonnay or a light Pinot Noir.
Leftovers Transformation
You can turn any leftover bake into a whole new dinner by pulling apart the chicken and veggies, then mixing them with cooked pasta and a dash of cream for a quick pasta dish. Or use the leftovers as filling for a pastry-topped pie, or blend with more stock to make a chunky soup. The flavors actually get better overnight, so sometimes the leftovers taste even better than the first serving.
