Ingredients

Scale
  • 2 lbs cooked and shredded chicken breast (rotisserie or leftover grilled/poached)
  • 2 cups broccoli florets, chopped (fresh or frozen, thawed and drained)
  • 1 cup cauliflower, chopped
  • 2 cups shredded cheddar cheese
  • 8 oz cream cheese, softened
  • 1 cup sour cream (or Greek yogurt)
  • 2 large eggs
  • 1/2 cup green onions, sliced
  • 1 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/2 tsp salt (or to taste)
  • 1/4 tsp black pepper (or to taste)
  • 1 tbsp olive oil
  • 1/4 tsp red pepper flakes (optional)

Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish with olive oil or nonstick spray.
  2. If using uncooked chicken, poach or bake until cooked through (about 20 minutes at 375°F). Shred with two forks. If using rotisserie, just shred and set aside.
  3. Heat olive oil in a skillet over medium heat. Add broccoli and cauliflower, sautéing for 4-5 minutes until just tender but still bright. Do not overcook.
  4. In a large mixing bowl, blend cream cheese and sour cream until smooth. Add eggs and whisk until creamy and lump-free.
  5. Add shredded chicken, sautéed veggies, green onions, garlic powder, onion powder, salt, pepper, and optional red pepper flakes. Stir to combine. If mixture looks dry, add another spoonful of sour cream.
  6. Pour mixture into prepared casserole dish. Sprinkle shredded cheddar cheese evenly over the top.
  7. Bake on the middle rack for 30 minutes, or until cheese is bubbly and golden. For a crispier top, broil for an extra 2-3 minutes at the end.
  8. Remove from oven and let cool for 5-10 minutes before slicing and serving.

Notes

Use room temperature dairy for a smoother sauce. Drain veggies well to avoid a watery casserole. Shred your own cheese for best melt. Let casserole rest before slicing for clean servings. Swap veggies or cheese as desired; recipe is flexible. Can be made ahead and refrigerated or frozen.
