- 12 beaten eggs

Cheese
- 1 cup shredded cheddar cheese (about 4 oz)
Instructions
- Preheat the Oven and Prepare the Baking Dish: Preheat your oven to 350 degrees Fahrenheit. Grease a 9×13-inch baking dish thoroughly to prevent sticking and set it aside for later use.

- Add Cheese and Transfer to Baking Dish: Stir the shredded cheddar cheese into the egg and bacon mixture to ensure an even distribution of cheese throughout the casserole. Pour the combined mixture into the prepared 9×13-inch baking dish and spread it out evenly.
- Bake and Serve: Place the baking dish into the preheated oven and bake for 25 to 30 minutes, or until the top is fully set and lightly golden brown. Remove from oven and allow it to cool for 5 minutes before slicing and serving warm. Enjoy your hearty egg bake casserole!
