Preparation Phase & Tools to Use (Essential Tools and Why They Matter)

To make this casserole, you’ll need a large mixing bowl to whisk the eggs and combine ingredients evenly. A whisk or electric mixer is handy for incorporating air into the eggs, ensuring the casserole bakes up light and fluffy. Use a ceramic or glass baking dish (about 9×9 inch) for even heat distribution, giving you a golden, tender finish. A spatula or wooden spoon will help you fold in add-ins like shredded cheese and veggies without deflating the mixture. Lastly, a sharp knife and cutting board are key for prepping herbs, onions, or any additional toppings you love.
