Ingredients

Scale
  • 2 lbs boneless, skinless chicken breasts or thighs, cut into bite-sized pieces
  • 1 packet (1 oz) ranch seasoning mix
  • 1 tbsp olive oil (for chicken)
  • 1/2 tsp garlic powder
  • Salt & pepper, to taste
  • 3 cups fresh broccoli florets, cut small
  • 1 tbsp olive oil (for broccoli)
  • Pinch salt
  • 1 can (10.5 oz) cream of chicken soup
  • 1/2 cup sour cream
  • 1/2 cup milk (whole or 2%)
  • 1 1/2 cups shredded cheddar cheese
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated parmesan cheese
  • 1 cup panko breadcrumbs
  • 2 tbsp melted butter
  • 2 tbsp grated parmesan cheese (for topping)
  • 1/2 tsp dried parsley

Instructions

  1. Preheat oven to 400°F. Lightly grease a 9×13-inch baking dish.
  2. Toss broccoli florets with 1 tbsp olive oil and a pinch of salt. Spread on a baking sheet and roast for 10-12 minutes until slightly charred. (If using frozen broccoli, thaw, pat dry, and skip roasting.)
  3. Heat 1 tbsp olive oil in a large skillet over medium-high. Add chicken pieces, sprinkle with ranch seasoning, garlic powder, salt, and pepper. Sear for 5-6 minutes until golden (they don’t need to be fully cooked).
  4. In a mixing bowl, whisk together cream of chicken soup, sour cream, milk, cheddar cheese, mozzarella cheese, and 1/4 cup parmesan until smooth.
  5. Layer seared chicken and roasted broccoli in the prepared baking dish. Pour cheese sauce evenly over the top and spread with a spatula.
  6. In a small bowl, mix panko breadcrumbs, melted butter, 2 tbsp parmesan, and parsley. Sprinkle evenly over casserole.
  7. Bake for 25-30 minutes until bubbling and topping is golden brown. If topping browns too quickly, cover loosely with foil for the last 10 minutes.
  8. Let casserole rest for 5-10 minutes before serving. Slice and serve hot.

Notes

For gluten-free, use GF panko and cream soup. Rotisserie chicken can be substituted for raw chicken to save time. Roasting broccoli adds flavor; don’t skip it. Use freshly shredded cheese for best melt. Assemble ahead and refrigerate, adding topping just before baking. For a crispier topping, broil for 2 minutes at the end. Leftovers reheat well; broil to restore crunch.
