Main Ingredients

  • 2 tablespoons butter
  • 4 cups sliced yellow squash
  • 1 medium onion, chopped
  • 2 large eggs
  • 1 cup grated cheddar cheese
  • 1 cup milk
  • 2 tablespoons butter
  • ¼ teaspoon cayenne pepper (optional)
  • ½ teaspoon kosher salt
  • ½ teaspoon ground black pepper
  • 1 sleeve Ritz crackers

Instructions

  1. Preheat Oven: Preheat your oven to 350ºF to prepare for baking the casserole.
  2. Cook Squash and Onions: Melt 2 tablespoons of butter in a medium skillet over medium-low heat. Add the sliced yellow squash and chopped onion, cooking until both are tender, which enhances their natural flavors and softens their texture.
  3. Prepare Casserole Mixture: In a large bowl, lightly whisk the eggs. Add grated cheddar cheese and milk to the eggs and whisk until well combined. Stir in the cooked squash and onions. Melt the remaining 2 tablespoons butter in the skillet used previously, then add it to the mixture. Season with cayenne pepper if using, kosher salt, and ground black pepper. Mix everything thoroughly to distribute flavors evenly.
  4. Assemble Casserole: Spray a 9×13-inch casserole dish with cooking spray for easy removal and layering. Pour the squash mixture into the dish, smoothing it evenly. Top the casserole with crushed Ritz crackers for a crunchy topping.
  5. Bake: Place the casserole in the preheated oven and bake for 45 minutes. Bake until the top is lightly browned and the casserole is set, without jiggle when you move the dish, ensuring it is fully cooked.
  6. Rest and Serve: Allow the casserole to sit for about 3 minutes after removing it from the oven to set further. Then serve warm for best flavor and texture.

Notes

  • Optional cayenne pepper adds a mild heat that complements the creamy casserole, but it can be omitted if preferred.
  • Using Ritz crackers as topping adds a delicious buttery crunch; substitute with breadcrumbs if necessary.
  • Be sure not to overcook the squash initially; it should be tender but not mushy to keep a good texture in the casserole.
  • This casserole can be made a day ahead and reheated before serving for convenience.
  • For a lighter version, use low-fat milk and reduced-fat cheddar cheese.
