Ingredients for Bacon and Egg Breakfast Casserole

Instructions

  1. Preheat oven – Preheat your oven to 350ºF/180ºC and grease a deep sided 9 x 9 inch casserole dish. Set aside.
  2. Whisk eggs – In a large mixing bowl whisk together the eggs, milk, salt and pepper. Set aside.
  3. Cook bacon, peppers and onions – Heat a medium sized skillet over medium heat and add the bacon. Stir well to break up the chopped bacon and cook until it starts to become crisp, about 5 – 7 minutes. Remove the bacon from the skillet. Add the peppers and onions to the same skillet and cook until softened, about 5 minutes. Remove from heat.
  4. Finish egg mixture – Add the bacon, peppers and cheese (reserving about 3 – 4 tablespoons of the cheese) to the egg mixture and stir well to combine.
  5. Bake – Pour the egg mixture into your prepared casserole dish and sprinkle over remaining cheese. Place in the preheated oven and bake between 50 minutes and one hour. Insert a toothpick into the centre to ensure the eggs have fully cooked through.
  6. Serve – Remove from oven and allow to cool for about 10 minutes before cutting and serving.

Recipe Tips

  • Dish size – I baked this in a 6 x 8 inch backing dish. It took a full hour to bake. However, you can use a 8 x 8, 9 x 9 or even a larger baking dish. the bigger the baking dish, the less time your will have to bake this for. So just cut back the baking time if you are using a larger dish.
  • Cover if browning – Keep an eye on the casserole and if it’s browning too quickly lay a sheet of aluminium foil over the top so it doesn’t burn.

  • Milk – I used whole milk, but you can use half and half or use half whole milk and half sour cream.
  • Red onions – Feel free to use any kind of onions for this recipe. You can use white, brown or even spring onions.
  • Bacon – I used thin cut bacon. You could use ground turkey or ground sausage.
