Let’s Make it Happen!

  • Preheat your oven to 375°F (190°C). While it warms, gather your ingredients for this chicken leek and butternut squash bake — prepping ahead makes the whole process smoother.
  • Heat the olive oil in an oven-safe skillet or casserole dish over medium heat. Add the chicken thighs seasoned with salt, pepper, and dried thyme. Sear each side for about 3 minutes until golden but not fully cooked through. This step locks in flavor and starts the comforting roasted chicken casserole magic.
  • Remove the chicken and set it aside. In the same pan, toss in the sliced leeks and minced garlic. Sauté for 5 minutes until soft and fragrant. The smell of these slowly cooking leeks signals the creamy leek sauce is on its way.
  • Add the butternut squash cubes to the pan and stir gently with the leeks. Pour in the chicken broth and heavy cream. Bring the mixture to a simmer, letting it thicken a bit—this is where your creamy leek sauce starts to take shape in your chicken leek and butternut squash bake.
  • Nestle the chicken back into the sauce. If you’re using, sprinkle the shredded cheese on top. Pop your dish into the preheated oven.
  • Bake uncovered for 30-35 minutes until the chicken is cooked through and the butternut squash is tender. You want to see a bubbly, creamy sauce around the edges of your chicken leek and butternut squash bake.
  • While it’s baking, take a breath and maybe prep tomorrow’s lunch or sit down for a coffee. The kitchen smells comforting, and you can almost feel your family gathered around the table soon.
  • Pull the casserole out and give it a moment to cool before serving. Don’t worry if your chicken leek and butternut squash bake looks a little rustic—that homemade comfort is all part of the charm.

This timing fits perfectly into a busy mom’s hectic schedule without sacrificing dinner quality. It’s a cozy, creamy comfort food bake where every step brings you closer to that homemade magic.
