Ingredients
  

Cheesy broccoli casserole
  • 2 lb broccoli florets Steam until crisp-tender, then drain well.
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 cup mayonnaise
  • 2 large eggs
  • 1 small onion, finely diced
  • 1.5 cup shredded sharp cheddar Use 1 1/2 cups in the filling.
  • 0.5 cup shredded sharp cheddar Use remaining cheddar on top.
  • 0.5 tsp salt
  • 0.25 tsp black pepper
  • 1 sleeve Ritz crackers Crush crackers for the topping.
  • 3 tbsp butter, melted Toss with crushed crackers.

Equipment

  • 1 sheet pan
  • 1 9x13 inch baking dish

Method
 

Prep and bake
  1. Preheat the oven to 350F, then grease a 9x13-inch baking dish so the casserole releases easily.
  2. Steam the broccoli florets for 4-5 minutes until crisp-tender, then drain well to prevent a watery casserole.
  3. In a mixing bowl, combine cream of mushroom soup, mayonnaise, eggs, onion, 1 1/2 cups shredded cheddar, salt, and black pepper until evenly mixed.
  4. Fold the steamed broccoli into the soup mixture and spread it into the greased baking dish, then sprinkle with the remaining cheddar.
  5. Toss crushed Ritz crackers with melted butter, then sprinkle the crumb topping evenly over the casserole.
  6. Bake for 30-35 minutes at 350F until the casserole is bubbly and golden on top.

Notes

For the best texture, steam only until crisp-tender and drain very well—excess moisture can make the filling loose. Refrigerate leftovers in a covered container for up to 3 days; reheat in a 350F oven until warmed through. Freezing is not recommended because the creamy soup-and-mayo mixture can separate when thawed. Dietary swap: use a reduced-fat mayonnaise and cheese for a lighter version without changing the bake time.
