  • Large skillet

  • 9×13-inch baking dish
  • Wooden spoon
  • Cutting board
  • Measuring cups

Step-by-Step Instructions


  1. Preheat your oven to 350°F (175°C). This allows the casserole to cook evenly and helps develop the flavors.



  2. Heat olive oil in a large skillet over medium heat. Add the diced chicken, seasoning it with salt, pepper, and Italian seasoning. Cook for about 5–7 minutes, stirring occasionally, until the chicken is just browned and mostly cooked through. Remove from heat and set aside.



  3. In the same skillet, add the diced onion and minced garlic. Sauté for 2–3 minutes until the onion becomes translucent and fragrant.



  4. Add broccoli, cauliflower, and bell peppers to the skillet. Cook for an additional 4–5 minutes until the vegetables begin to soften, retaining some crunch for texture.



  5. In a mixing bowl, combine the heavy cream, shredded cheddar cheese, and grated Parmesan cheese. Stir until well blended and creamy, then pour over the chicken and vegetable mixture. Mix thoroughly to ensure everything is evenly coated.



  6. Transfer the mixture into a greased 9×13-inch baking dish. Spread it out evenly to ensure even cooking.



  7. Bake in the preheated oven for 30–35 minutes or until the top is golden and bubbly, and the casserole is heated through. The aromatic scent will fill your kitchen as it cooks.



  8. Once out of the oven, allow it to cool for a few minutes. Garnish with fresh parsley before serving.
