Ingredients

  • 1 lb. (450g) boneless skinless chicken breast , cut into bite-size pieces
  • 4 tablespoons (30g) all-purpose flour
  • 1 tablespoon (15ml) olive oil
  • 1 tablespoon (15g) unsalted butter
  • 7 oz. (200g) butternut squash , peeled and cut into cubes
  • 1 leek , white and light green parts only, halved and chopped
  • 1 ¼ cups (300ml) heavy cream
  • 3.5 oz. (100g) blue cheese , crumbled
  • 5 oz. (140g) grated mozzarella cheese
  • 1 medium head of cauliflower , about 1 lb. (450g)
  • salt and black pepper , to taste

Instructions

  • Preheat the oven to 400°F (200°C).
  • In a medium bowl, toss chicken pieces with all-purpose flour until covered and shake of any excess.
  • In a large pan, heat the olive oil and butter over medium-high heat. Add the chicken pieces and brown them on all sides, around 5 minutes.
  • Add in the butternut squash and leek to the pan and fry for 5 minutes more, stirring occasionally.
  • Pour in the heavy cream, add the crumbled blue cheese and half of the grated mozzarella cheese. Season with salt and black pepper, to taste, and mix everything together.
  • Transfer the mixture into the large baking dish.
  • Remove the hard stem of the cauliflower. Using your sharpest chef’s knife, cut cauliflower into 1/2-inch slices (florets will likely fall apart, no worries). Layer the cauliflower slices on top of the chicken mixture. Sprinkle the rest of the grated mozzarella cheese on top.
  • Bake for 30 minutes, until golden brown.
