Ingredients For Squash Egg And Cheese Casserole
Squash: A versatile vegetable that adds a subtle sweetness and tender texture to the casserole.
Eggs: These provide structure and a creamy texture to the dish.
Cheese: Shredded cheese adds a savory flavor and melty goodness on top.
Milk: This helps to create a smooth and creamy consistency in the egg mixture.
Salt: Enhances the overall flavor of the casserole.
Black pepper: Adds a hint of spice and depth to the dish.
Technique Tip for This Recipe
When preparing the squash, make sure to slice it evenly to ensure uniform cooking. A mandoline slicer can be particularly useful for this task, providing consistent thickness and helping the casserole cook more evenly. Additionally, consider lightly sautéing the squash slices in a bit of olive oil before layering them in the baking dish. This can help to enhance their flavor and reduce excess moisture, resulting in a firmer, more cohesive casserole.
