Instructions

1. Preheat and Prepare Dish: Preheat your oven to 375 degrees F (191 degrees C). Grease the bottom of a large baking dish to prevent sticking and ensure easy serving.

4. Cook Vegetables: Add the minced garlic, diced bell peppers, and sliced mushrooms to the skillet. Continue cooking for 6-8 minutes until the vegetables soften and release their aromas.
5. Combine Ham and Veggies: Remove the skillet from heat. Stir the browned ham back into the vegetable mixture. If using green onions, stir them in now. Transfer this mixture evenly into the prepared baking dish.
6. Prepare Egg Mixture: In a large bowl, whisk together 12 eggs, half and half (or milk), 1 cup of shredded cheese, sea salt, and black pepper until fully combined and smooth.
7. Assemble Casserole: Pour the egg mixture over the ham and vegetable layer in the baking dish. Stir gently to combine the layers slightly. Then, sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top.
8. Bake: Place the casserole in the preheated oven and bake for about 30 minutes. The casserole is ready when the eggs are set but still soft in the center and the edges have turned a golden brown.
