A comforting cheesy summer squash casserole featuring tender squash, sharp cheddar cheese, and a crunchy cornflake topping, perfect for family dinners or potlucks.

Ingredients

2 small yellow summer squash, sliced

1/4 cup chopped onion

1/2 teaspoon salt, divided

1 large egg

1/4 cup mayonnaise

2 teaspoons sugar

Pepper to taste

1/4 cup shredded cheddar cheese

2 tablespoons crushed cornflakes

1-1/2 teaspoons butter, melted

Instructions

  1. Prepare the Squash: In a small saucepan, combine the sliced squash, chopped onion, and 1/4 teaspoon of salt. Cover with water and bring to a boil over medium-high heat. Reduce heat and simmer, uncovered, until the squash is crisp-tender, about 2 minutes. Drain thoroughly to remove excess water.
  2. Make the Casserole Mixture: In a small bowl, whisk together the egg, mayonnaise, sugar, pepper, and the remaining 1/4 teaspoon of salt until well blended. Stir in the shredded cheddar cheese and the drained squash mixture, ensuring everything is evenly combined.
  3. Assemble the Casserole: Preheat your oven to 350°F (175°C). Grease a 2-cup baking dish. Transfer the squash mixture into the prepared dish, spreading it out evenly.
  4. Prepare the Topping: In a small bowl, combine the crushed cornflakes and melted butter, tossing to coat the cornflakes evenly. Sprinkle the buttered cornflakes over the top of the casserole.
  5. Bake the Casserole: Place the baking dish in the preheated oven and bake, uncovered, until the top is golden brown and the casserole is bubbly, about 25-30 minutes. Allow to cool slightly before serving.
