Equipment

  • Large skillet
  • Crockpot
  • Spatula or spoon for serving
  • Cooking spray

Ingredients
  

  • 11 tbsp ground mustard
  • 1 cup milk
  • 2  eggs, beaten
  • 1 package shredded Cheddar cheese
  • 1 package of frozen hash brown potatoes thawed
  • 1 package maple-flavored sausage
  • salt and ground black pepper to taste

Instructions
 

  • Lightly coat the inside of your slow cooker with cooking spray.
  • Evenly layer the hash browns to cover the bottom of the crock.
  • In a mixing bowl, whisk together the eggs, milk, mustard, salt, and black pepper until well combined.
  • Heat a large skillet over medium-high heat and cook the sausage, stirring frequently, until it’s browned and crumbly, about 5 to 7 minutes.
  • Drain the grease and spread the sausage over the hash browns in the slow cooker.
  • Sprinkle the Cheddar cheese evenly over the sausage layer.
  • Carefully pour the egg mixture over the top, ensuring everything is covered.
  • Cover the slow cooker with the lid and cook on Low for 6 to 8 hours, until the eggs are set and cooked through.

  • Substitute the sausage with turkey sausage or vegetarian crumbles for a lighter option.
  • Use sharp Cheddar or a cheese blend for a richer, more robust taste.
