Ingredients
  

  • 3 cups cooked chicken, shredded or cubed (rotisserie works great)
  • 2 cups broccoli florets, lightly steamed or blanched
  • 1 small head cauliflower, cut into small florets and lightly steamed
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 4 oz cream cheese, softened
  • 1/2 cup sour cream (or full-fat Greek yogurt)
  • 1/2 cup chicken broth, preferably low sodium
  • 1 1/2 cups shredded cheese, divided (cheddar, Monterey Jack, or a blend)
  • 2 tbsp olive oil or butter
  • 1 tsp Dijon mustard
  • 1/2 tsp smoked paprika (optional but recommended)
  • 1/2 tsp dried thyme or Italian seasoning
  • Salt and black pepper, to taste
  • Fresh parsley, chopped, for garnish

Method
 

  1. Prep the oven and pan: Heat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
  2. Partially cook the veggies: Steam or microwave the broccoli and cauliflower just until crisp-tender, about 3–4 minutes. Drain well and pat dry to avoid a watery casserole.
  3. Sauté aromatics: In a skillet, heat olive oil or butter over medium heat. Cook the onion 3–4 minutes until soft, then add garlic for 30 seconds until fragrant. Remove from heat.
  4. Make the creamy sauce: In a large bowl, whisk cream cheese, sour cream, and chicken broth until smooth. Stir in Dijon, smoked paprika, thyme, 1 cup of the shredded cheese, and a good pinch of salt and pepper.
  5. Combine: Add cooked chicken, sautéed onions and garlic, and the drained broccoli and cauliflower to the bowl. Toss until everything is coated in the sauce.
  6. Assemble: Spread the mixture evenly in the prepared baking dish. Sprinkle the remaining 1/2 cup cheese over the top.
  7. Bake: Bake for 18–22 minutes, until the casserole is bubbling and the cheese is melted and lightly golden.
  8. Finish and serve: Let it rest 5 minutes. Garnish with chopped parsley, taste, and adjust salt and pepper if needed. Serve warm.
