  • Non-stick cooking spray
  • 1 28-ounce package frozen hash brown potatoes
  • 16 ounces vegan breakfast sausage
  • 1/4 cup yellow onion diced
  • 1 red bell pepper seeded and chopped
  • 1 green bell pepper seeded and chopped
  • 2 cups vegan cheddar cheese shredded
  • 1 12-ounce bottle vegan liquid egg substitute, recommend Just Egg brand
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon ground black pepper


  • Preheat the oven to 350°F. Spray a 9x13-inch baking dish with non-stick cooking spray.
  • In a large deep skillet, cook the hash browns according to package directions. Arrange the cooked hash browns in the prepared baking dish, creating the bottom layer of the casserole.
  • Using the same skillet, cook the sausage according to its package directions. Halfway through the cooking time, add the onion and bell peppers. Continue cooking for 2-3 minutes, until sausage is done. Spread the sausage and peppers mixture over the hash browns to form the second layer of the casserole.
  • For the top layer, sprinkle with cheddar cheese to cover the entire casserole.
