Step 1: Cauliflower Prep

  1. Preheat and Cut:
  • Preheat your oven to 375°F (190°C). Cut the cauliflower into bite-sized pieces.
  1. Toss in Olive Oil:
  • Place the cauliflower pieces on a baking sheet, drizzle with olive oil, and season with salt and pepper. Toss to coat evenly.
  1. Roast the Cauliflower:
  • Roast in the preheated oven for 20-25 minutes or until the cauliflower is tender and slightly browned. Set aside.

Step 2: Sauce Creation

  1. Butter and Flour Magic:
  • In a saucepan, melt 1/4 cup of butter over medium heat. Stir in the flour to create a roux, cooking for 1-2 minutes.
  1. Introduce Chicken Stock:
  • Gradually whisk in the chicken stock, ensuring no lumps form. Allow the mixture to thicken, stirring continuously.
  1. Cheesy Symphony:
  • Add 1 cup of shredded Cheddar cheese to the sauce, stirring until melted and smooth. Remove from heat.

Step 3: Casserole Assembly

  1. Combine Cauliflower and Sauce:
  • In a large bowl, combine the roasted cauliflower with the cheesy sauce, coating the cauliflower evenly.
  1. Layer in a Greased Dish:
  • Grease a baking dish with butter and layer half of the cauliflower mixture at the bottom.
  1. Chicken and Green Onions:
  • Sprinkle the chopped cooked chicken and green onions over the cauliflower layer.
  1. Repeat Layers:
  • Add the remaining cauliflower mixture as the next layer. Top with the remaining shredded Cheddar cheese.
  1. Final Touch – Bacon:
  • Sprinkle the crumbled bacon over the top for that irresistible savory finish.

Step 4: Bake to Perfection

  1. Into the Oven:
  • Bake the casserole in the preheated oven for 25-30 minutes or until it’s bubbling, golden, and irresistibly aromatic.
  1. Cool and Serve:
  • Allow the casserole to cool for a few minutes before serving. Garnish with extra green onions and bacon if desired.

Cook Notes and Variations

  • Cauliflower Substitution:
  • Swap cauliflower with broccoli for a slight variation in flavor and texture.
  • Cheese Medley:
  • Experiment with different cheeses like Monterey Jack, Gouda, or Swiss to create a personalized cheesy blend.
  • Herb Infusion:
  • Add fresh or dried herbs such as thyme, rosemary, or parsley to elevate the dish’s aromatic profile.
  • Vegetarian Twist:
  • Skip the chicken and bacon for a hearty vegetarian version. Consider adding extra vegetables like bell peppers or mushrooms.
