Beat 12 eggs until well blended.
Next, beat in milk and garlic powder, mustard, 1 tsp salt & 1/2 tsp pepper. Set aside.
Layer potatoes and sprinkle 1/3 of the onions.
Next sprinkle 1/3 of the bacon.
Last but not least, top with 1 cup of cheese.
Repeat this layering 2 more times to have a total of 3 layers….ending with cheese.
Take your egg mixture and pour over layers.
You can use frozen hash browns, just cook for 8-9 hours, instead of the 7-8.
You may also want to add an additional pinch of salt and pepper for each layer of hash browns you use.
