- Step 4: In a large bowl, whisk together cream of mushroom soup, milk, sour cream, mayonnaise, thyme, salt, and black pepper. Add cooked chicken and broccoli mixture, stirring gently to combine.
- Step 5: Pour the chicken mixture into a greased 9×13 inch baking dish. Sprinkle cheddar and Monterey Jack cheeses evenly over the top.
- Step 6: In a small bowl, combine crushed Ritz crackers with melted butter. Sprinkle this mixture evenly over the cheese layer.
- Step 7: Bake for 20-25 minutes, until the casserole is bubbly and the topping is golden brown. Let rest for 10 minutes before serving.
Tips & Variations

- Add a pinch of smoked paprika or cayenne pepper to the sauce for a subtle kick.
- Swap the Ritz cracker topping with panko breadcrumbs mixed with Parmesan for extra crunch.
Storage
