Chicken Leek and Butternut Squash Bake is a cozy, comforting dish that blends tender chicken breast, sweet roasted butternut squash, and delicate leeks in a creamy, cheesy sauce. Perfect for a nourishing family dinner or make-ahead meal.


Ingredients

Units Scale
  • 1 tbsp olive oil
  • 1 lb chicken breast, diced
  • 2 cups butternut squash, peeled and cubed
  • 2 large leeks, cleaned and sliced
  • 2 cloves garlic, minced
  • 1 tsp thyme (fresh or dried)
  • Salt and pepper, to taste
  • 1/2 cup chicken broth
  • 1/2 cup heavy cream or crème fraîche
  • 1/2 cup grated Parmesan cheese
  • 1/4 tsp ground nutmeg
  • 1/2 cup breadcrumbs (optional)
  • Cooking spray or butter for greasing

Instructions

  1. Preheat oven to 375°F (190°C) and lightly grease a baking dish.
  2. Heat olive oil in a skillet over medium heat. Add chicken, season with salt and pepper, and cook until no longer pink. Remove and set aside.
  3. In the same skillet, sauté leeks for 5 minutes until softened. Add garlic and thyme, cooking for another minute.
  4. Add the butternut squash and cook for 5 minutes until slightly golden.
  5. Return the chicken to the skillet. Stir in broth, cream, nutmeg, and half the Parmesan. Simmer for 2–3 minutes.
  6. Transfer everything to the prepared baking dish. Top with remaining Parmesan and breadcrumbs.
  7. Bake for 25–30 minutes, until the top is golden and bubbly.
  8. Let rest for 5 minutes before serving.

Notes

  • Swap cream for Greek yogurt for a lighter version.
  • Use gluten-free breadcrumbs to make it gluten-free.
  • Add chopped kale or spinach for extra veggies.
