How to Make Breakfast Casserole
Start by preheating your oven to 375°F, and then break all the eggs into a large bowl and add half of the cheese along with salt, pepper, and garlic if you are adding it.
Next, prepare the vegetables including the green onions, bell pepper, and mushrooms by cutting them into small pieces. Break up the already cooked bacon into small pieces too.
Get your 9 x 13 ovenproof baking pan and grease the sides a little then evenly spread the vegetables and bacon pieces into the dish and then pour over the beaten egg and cheese mixture and sprinkle over the rest of the cheese.
Your breakfast casserole will take about 30-40 minutes to fully bake but oven temperatures vary so be sure to check it so it does not overcook.

Make Ahead and Freezing Tips
Make ahead – my favorite way to do this is to prepare all vegetables ahead of time, place them into the greased 9×13 pan along with the bacon pieces and cling wrap it in the fridge. Then simply whisk the egg, cheese, salt, pepper and garlic together in a bowl and cover and store them in the fridge overnight. All you need to do in the morning is pour over the egg mixture and bake it.
Freeze it – I like to portion up the cooked breakfast casserole and place it into freezer bags. You can defrost in the fridge overnight or use the microwave to defrost and reheat.
