Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.
In a large bowl, mix the cooked broccoli, mayonnaise, cheddar cheese, soup, and eggs until well combined.
Spread the mixture evenly in the prepared baking dish.
In a separate bowl, combine the crushed crackers with melted butter, then sprinkle this topping over the casserole.
Bake in the preheated oven for 30-35 minutes or until the topping is golden brown and the casserole is bubbly.
Serve warm and enjoy!
