Broccoli Souffle with Cream of Mushroom Soup

Preheat the oven to 300 degrees F (150 degrees C).

Bring a large pot of water to a boil. Add broccoli. Cook until heated through, 3 to 5 minutes. Drain well.

Transfer broccoli to a bowl. Mix in mushroom soup, mayonnaise, and eggs until well blended. Pour into a baking dish and sprinkle with Cheddar cheese.

Bake in the preheated oven until lightly browned, about 30 minutes.
