Let’s dive into making this nourishing chaos easier on our families and ourselves!
INGREDIENTS You’ll Need:
Here’s a simple but star-studded ingredient list for your chicken leek and butternut squash bake. Trust me, it’s straightforward because busy moms need nutrition without complexity!

- 4 boneless, skinless chicken thighs (about 1.5 lbs) – Dark meat stays juicy and full of flavor; also rich in iron.
- 1 medium butternut squash (about 3 cups cubed) – Loaded with vitamin A and fiber. No worries if you don’t have butternut squash—you can substitute with sweet potatoes for a similar nutrition boost.
- 2 large leeks (white and light green parts only), sliced and rinsed well – They bring in vitamins A, C, and K along with fibers.
- 2 cloves garlic, minced – A natural immune support powerhouse.
- 1 cup low-fat Greek yogurt – Adds creaminess and protein without extra fat.
- 1/2 cup shredded mozzarella cheese – For that melty topping your family will adore.
- 1 tablespoon olive oil – Good fats to keep energy steady.
- 1 teaspoon dried thyme – Adds lovely herbal notes without sodium.
- Salt and pepper, to taste
- Optional: 1/2 cup spinach or kale, chopped – For an extra green nutrition punch. My family loves when I sneak this in—it ups the fiber and vitamin C.
You can find these wholesome ingredients at your regular grocery store without hunting specialty shops. If your local store doesn’t have leeks, mild yellow onions make a decent substitute. And for milk alternatives, a splash of unsweetened almond or oat milk works if you’re skipping dairy.
This chicken leek and butternut squash bake proves nutritious doesn’t mean expensive or complicated! The key is clean, simple ingredients that multitask nutrition-wise. A little prep like cubing the squash ahead on a weekend can save minutes on busy nights too.
Let’s Make it Happen!
Are you ready? This chicken leek and butternut squash bake is easier than you think. I’m right here cooking alongside you, cheering you on through the nourishing chaos!
- Preheat your oven to 375°F (190°C).
- Prepare the butternut squash: Peel, seed, and cube your squash into bite-sized pieces. If you’re pressed for time, buying pre-cut squash works perfectly and saves prep hassle.
- Sauté the leeks and garlic: Heat olive oil in a large skillet over medium heat. Add the sliced leeks and minced garlic, cooking until soft but not browned, about 4-5 minutes. This step builds flavor for your creamy chicken and vegetable bake foundation.
- Brown the chicken thighs: Push the leeks to the side and add chicken to the skillet skin side down. Let them brown for about 5 minutes per side. Don’t worry if they aren’t fully cooked yet—that happens in the oven. Browning adds texture and flavor that your family will notice.
- Combine the ingredients: In a large casserole dish, spread the cubed butternut squash evenly, then top with the leek and chicken mixture. If adding spinach or kale, sprinkle it on now.
- Mix the creamy goodness: In a small bowl, blend the Greek yogurt with dried thyme, salt, and pepper. Pour this sauce over the chicken and vegetables, spreading evenly to coat.
- Top with cheese: Sprinkle shredded mozzarella evenly on top. It melts into a golden crust that kids find irresistible.
- Bake uncovered for 35-40 minutes: Your chicken leek and butternut squash bake should smell nourishing and look bubbly by now.
- Check doneness: Make sure chicken juices run clear and squash is tender when poked with a fork.
- Let it rest for 5 minutes: This helps the flavors settle. Perfect time to prep tomorrow’s lunch or throw together school snacks!
I used to struggle with uneven cooking, but spacing the ingredients in a single layer helped me get a perfect roast on the chicken and vegetables. If your chicken leek and butternut squash bake looks a little watery, don’t worry—it thickens as it rests.
