Ingredients

Scale

Main Vegetables:

  • 4 cups yellow squash (sliced 1/4-inch thick)
  • 4 cups zucchini (sliced 1/4-inch thick)
  • 2 cups cooked corn
  • 1 1/2 cups coarsely chopped sweet or yellow onion

Dairy and Binding Ingredients:

  • 2 cups shredded sharp cheddar cheese
  • 1/2 cup mayonnaise
  • 1/2 cup sour cream
  • 2 large eggs, lightly beaten
  • 2 tablespoons salted butter, melted

Seasonings and Topping:

  • 4 cups chicken broth
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 1/2 cups coarsely crushed Ritz crackers

Instructions

  1. Prepare oven by heating to 350°F (175°C) and lightly grease a baking dish.
  2. Fill a large pot with chicken broth and bring to a rolling boil, then carefully add sliced squash, zucchini, and chopped onion.
  3. Simmer vegetables until they become tender but not mushy, approximately 4-5 minutes.
  4. Drain vegetables thoroughly in a colander, allowing excess liquid to escape.
  5. Transfer drained vegetables to a spacious mixing bowl and gently fold in sweet corn kernels.
  6. Incorporate mayonnaise, sour cream, whisked eggs, melted butter, salt, and pepper into the vegetable mixture, stirring until evenly combined.
  7. Fold in sharp cheddar cheese, ensuring ingredients are well distributed throughout the casserole base.
  8. Pour the creamy vegetable mixture into the prepared baking dish, spreading it evenly.
  9. Generously top the casserole with remaining cheese and crushed Ritz crackers, creating a crispy golden layer.
  10. Slide the casserole into the preheated oven and bake for 30-35 minutes until the surface turns golden brown and edges become bubbly.
  11. Remove from oven and allow the casserole to rest for 5-10 minutes before serving, which helps set the texture.

Notes

  • Swap out chicken broth for vegetable broth to create a vegetarian-friendly version of this comforting casserole.
  • For a gluten-free option, replace Ritz crackers with gluten-free breadcrumbs or crushed cornflakes for a crispy topping.
  • Experiment with different cheese varieties like Gruyère or pepper jack to add unique flavor dimensions to the dish.
