There’s a kind of magic that happens when autumn rolls around and the kitchen transforms into a place of warmth and comfort. It was during one of these crisp fall evenings that I first attempted a Chicken, Leek, and Butternut Squash Bake. Picture this: I had my heart set on a cozy, one-dish dinner, but as I peered into the oven, I realized my squash was still rock-hard and the chicken, well, let’s just say it was embarrassingly underdone. Lesson learned—always check your oven temperature and give your squash a head start!
Since then, I’ve perfected this recipe, and now it’s a staple in my home. The kids come running when they catch the aroma of caramelized leeks and roasting chicken wafting through the house. It’s the kind of dish that beckons you to the table, promising warmth and nourishment. And believe me, once you’ve tried it, it’ll become a beloved addition to your own recipe collection.

Ingredients
My mom always said the best meals start with fresh, simple ingredients. Here’s what you’ll need for this comforting bake:
- 1 medium butternut squash, peeled and diced
- 2 leeks, white and light green parts only, thinly sliced
- 4 boneless, skinless chicken breasts
- 3 tablespoons olive oil, divided
- 1 teaspoon dried thyme
- 1/2 teaspoon garlic powder
- Salt and freshly ground black pepper, to taste
- 1/2 cup chicken broth (homemade if you’ve got it!)
- Optional: grated Parmesan cheese for topping
Instructions
Now, about those instructions. Don’t worry, I’ve made every mistake in the book so you don’t have to (learned this the hard way).
- Preheat your oven to 400°F. You want it nice and hot to start roasting.
- Toss the diced butternut squash with 1 tablespoon of olive oil, a pinch of salt, and pepper. Spread it out on a baking sheet and roast for about 20 minutes or until it starts to soften.
- Meanwhile, heat the remaining olive oil in a large skillet over medium heat. Add the leeks and sauté until they begin to soften and caramelize. That smell is heavenly, right?
- Season the chicken breasts with thyme, garlic powder, salt, and pepper. Push the leeks to the side of the skillet and add the chicken. Sear it until golden on both sides. You’re not cooking it through just yet, just getting some color on it.
- Once the squash is out of the oven, reduce the temperature to 375°F. In a baking dish, combine the squash, leeks, and chicken. Pour the chicken broth over everything to keep it moist and create a bit of sauce.
- Cover with foil and bake for about 25-30 minutes, or until the chicken is cooked through. If you’re using a meat thermometer, you’re aiming for 165°F.
- Optional: In the last 5 minutes of baking, sprinkle some Parmesan cheese on top for a golden, cheesy crust—total game changer!
- Let it rest for a few minutes before serving. This gives the flavors time to meld together. Trust me on this.

Tips & Tricks
Alright, let’s dive into some insider knowledge. These tips will make your baking experience a breeze:
- Cooking Tips: Don’t skip pre-roasting the squash—it ensures everything cooks evenly. Also, let your chicken sit at room temperature for about 15 minutes before cooking to avoid it seizing up in the pan.
- Calories: This dish is relatively healthy, clocking in at around 400 calories per serving. Not bad for a dinner that feels indulgent.
- Substitutions: No leeks? Onions will work in a pinch. No butternut squash? Sweet potatoes are a fantastic substitute.
- Storage Tips: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave until warmed through.
- Variations: Mix it up by adding different herbs or spices. Rosemary and sage also pair beautifully with this dish.
FAQ
Got questions? I’ve got answers—and a few laughs from my own trial and error:
Q: My squash isn’t softening. What’s going on?
A: It sounds like your squash pieces might be too large or your oven isn’t hot enough. Cut them smaller next time and make sure your oven is fully preheated.
Q: Can I make this ahead of time?
A: Absolutely! Assemble everything in the bake dish, cover it, and store it in the fridge. When you’re ready, just pop it in the oven.
Q: How do I know when the chicken is done?
A: The best way is to use a meat thermometer. Otherwise, check that the juices run clear when you slice into the thickest part of the breast.
