Kelley Simmons Kelley’s Tips

Before You Get Started

  • Make ahead instructions: Assemble as directed and store in the fridge for up to 24 hours. When you are ready to bake allow the casserole to come to room temperature while the oven preheats and bake as directed. You may have to add an additional 5 minutes on to the cooking time.
  • Reheat Instructions: This reheats really well and keeps in the fridge for up to 4 days! You can freeze for longer in individual portions if desired!

Ingredients for Easy Breakfast Bake

  • Sausage: Feel free to use your favorite type of breakfast meat or omit to make the casserole vegetarian.
  • Vegetables: I use a mix of bell peppers, onions, mushrooms and spinach. Feel free to use whatever veggies you have on hand!
  • Eggs: We need 10 eggs for this breakfast bake.
  • Heavy Cream: In place of milk I used cream to create more of a custard for the egg filling!
  • Spices: Salt, pepper, garlic powder and onion powder are added.
  • Bread: I’ve used cubed brioche bread as well as French bread before and they both work great!
  • Cheese: I love using sharp cheddar cheese in this casserole however gruyere, pepper jack or Colby jack cheese would also be great.
