How to Make Chicken, Leek, and Butternut Squash Bake – One-Pan Comfort Food Recipe
Step 1: Preheat and Prep
Start by setting your oven to 375°F (190°C). Having the oven ready ensures when your bake is assembled, it goes in immediately for that perfect cook time and texture.
Step 2: Cook the Chicken
Heat the olive oil in a skillet over medium heat until shimmering. Add the diced chicken breast, seasoning with salt and pepper, and cook just until the pieces lose their pink color. This quick sear locks in flavor and juices that make every bite tender and delicious. Once done, transfer the chicken to a bowl and set aside.
Step 3: Sauté the Leeks and Garlic
In the same skillet, toss in the sliced leeks and cook until they’re soft and fragrant, about 5 minutes. Then add the minced garlic and thyme; let them cook together for another minute to build a fragrant, savory base for the dish.
Step 4: Add Butternut Squash
Now stir in the cubed butternut squash, allowing it to soften slightly but still hold its shape. Cooking it for about 5 minutes in the skillet helps deepen its naturally sweet flavor so it shines in the final bake.
Step 5: Combine Ingredients and Simmer
Return the cooked chicken to the skillet. Pour in the chicken broth and creamy element—either heavy cream or crème fraîche. Add half the grated Parmesan cheese, season with salt and pepper, then gently simmer the mixture for 2 to 3 minutes. The sauce will thicken a bit, enveloping all the ingredients in a luscious coating.
Step 6: Transfer to Baking Dish and Add Toppings
Pour everything into your baking dish, spreading it evenly. Sprinkle the remaining Parmesan cheese over the top and, if you like a little extra crunch, scatter the optional breadcrumbs to finish it off deliciously.
Step 7: Bake to Golden Perfection
Pop the dish into the preheated oven and bake for 25 to 30 minutes. You’ll know it’s ready when the top is bubbling and beautifully golden brown, creating that perfect crisp contrast to the creamy inside.
Step 8: Rest Before Serving
Once baked, let the dish rest for about 5 minutes. This little patience moment lets the flavors meld even further and allows the bake to settle for easier serving.

Garnishes
A sprinkle of fresh parsley or thyme leaves on top adds a fresh pop of color and herbaceous brightness, which brightens the richness of the dish beautifully. Alternatively, a few shavings of extra Parmesan cheese can heighten that cheesy indulgence.
Side Dishes
This bake is wonderfully filling on its own, but if you want to elevate the meal, consider pairing it with a crisp green salad dressed lightly with lemon vinaigrette or some roasted Brussels sprouts for a textural contrast and added nutrition.
Creative Ways to Present
For a fun twist, serve this bake in individual ramekins for a personal, elegant touch. You can also use it as a filling for puff pastry and bake until golden for a delightful variation that’s perfect for special dinners or entertaining guests.
Make Ahead and Storage
Storing Leftovers
Any leftovers from your Chicken, Leek, and Butternut Squash Bake – One-Pan Comfort Food Recipe can be stored in an airtight container in the fridge for up to 3 days. This makes it an excellent choice for next-day lunches or quick dinners during a busy week.
Freezing
If you want to keep it longer, freezing is a great option. Portion the bake into freezer-safe containers, and it will keep well for up to 2 months. Just be sure to cool it completely before freezing to maintain optimum texture and flavor.
Reheating
To reheat, thaw overnight in the fridge if frozen, then warm in the oven at 350°F (175°C) until heated through and bubbly, about 15-20 minutes. Alternatively, microwave portions can be warmed, though the oven will restore some of the original crispness on top.
FAQs
Can I use chicken thighs instead of chicken breasts?
Absolutely! Chicken thighs will add even more juiciness and flavor. Just be sure to cut them into similar-sized pieces and cook until they’re nicely browned and cooked through.
Is there a substitute for the heavy cream?
You can swap heavy cream with crème fraîche for a tangier, slightly lighter creaminess. For a dairy-free option, a full-fat coconut milk can work but will add a subtle coconut flavor.
Can this recipe be made vegetarian?
Yes! To make a vegetarian version, replace chicken with firm tofu or chickpeas and use vegetable broth instead of chicken broth. It will still be comforting and full of amazing flavors.
What if I don’t have leeks?
Onions or shallots are excellent substitutes. They have a similar sweetness and will work perfectly when sautéed before adding the squash.
Can I prepare this in advance and bake later?
Yes! Prepare the entire dish up to the baking step, cover, and refrigerate for up to 24 hours. When ready, just bake as directed, adding a few extra minutes if it’s coming straight from the fridge.
