Ingredients

Scale

Chicken

  • 1 1/3 lb boneless skinless chicken thighs, cut into thirds
  • 1 tsp dried parsley flakes
  • 1/2 tsp dried thyme
  • Salt and ground black pepper, to taste
  • Low-calorie oil spray (for frying)
  • 1 tbsp salted butter (or olive oil)

Vegetables and Broth

  • 1 yellow onion, sliced
  • 1 1/3 lb butternut squash, peeled and diced
  • 1 tsp paprika
  • 3 leeks, cleaned, trimmed, and sliced
  • 1 tbsp chopped garlic (or 3 garlic cloves, crushed)
  • 1 cup (8 fl oz) chicken broth (better than bouillon recommended)

Topping

  • 3 oz (80 g) freshly grated parmesan cheese
  • Fresh parsley leaves, chopped (about a handful)

Instructions

  1. Prepare and Sear Chicken: Preheat oven to 180°C fan (200°C/400°F/Gas Mark 6). Cut chicken thighs into thirds. Spray a large frying pan with low-calorie oil spray and heat over medium-high. Add chicken pieces seasoned with dried parsley, thyme, salt, and pepper. Fry until lightly golden on all sides, then remove and set aside.
  2. Sauté Vegetables: In the same pan, melt salted butter over medium heat. Add sliced onion, diced butternut squash, and paprika. Cook, stirring frequently, until the squash begins to soften.
  3. Deglaze and Add Broth: Gradually add small amounts of chicken broth, scraping the pan bottom to incorporate browned bits, enhancing flavor depth.
  4. Cook Leeks and Garlic: Add sliced leeks and chopped garlic to the pan. Continue cooking for 5 to 8 minutes, stirring occasionally until squash is tender and leeks are golden and softened.
  5. Assemble Bake: Transfer the vegetable mixture to a large ovenproof dish in an even layer. Arrange seared chicken pieces on top along with any juices. Pour over remaining chicken broth. Sprinkle grated parmesan evenly over the top.
  6. Bake Covered: Cover the dish with foil and bake for 15 minutes in the preheated oven.
  7. Bake Uncovered: Remove foil and bake for an additional 15 minutes, or until the top is golden and both chicken and squash are fully cooked. Optionally broil for a few minutes for extra color.
  8. Garnish and Serve: Remove from oven. Season with additional salt and pepper if desired. Sprinkle freshly chopped parsley over the top before serving.

Notes

  • Ensure the frying pan is hot before adding chicken to achieve a good golden sear.
  • Stir frequently during vegetable cooking to prevent sticking and ensure even cooking.
  • If you prefer a crispier top, broil the casserole for a few minutes after baking.
  • Better than bouillon chicken broth is recommended for richer flavor, but regular broth can be used as well.
  • This dish can be prepared ahead and baked when ready to serve.
