Cuisine: American, Mexican
Servings: 16

Ingredients

  • 1 (20-ounce) bag cooked shredded hash brown potatoes, thawed
  • 1 packet Old El Paso Taco Seasoning Mix
  • 1 pound chorizo, or pork sausage
  • 12 large eggs
  • 2 cups Mexican Cheese, shredded
  • ¼ cup milk
  • ½ teaspoon salt
  • ¼ teaspoon ground pepper
  • cups salsa

Instructions

  • Spray a 9x13-inch baking dish with cooking spray. Preheat the oven to 350°F.
  • Use a large mixing bowl to combine the hash browns and 1 tablespoon of the Taco seasoning. Toss until evenly coated, then gently press the mixture into the baking dish.
  • Heat a 10-inch skillet over medium-high heat. Spray with cooking spray and add the chorizo (sausage). Cook for 5-7 minutes or until cooked through, drain.
  • While the chorizo is cooking, in a medium mixing bowl, beat the eggs, milk, salt, pepper, and the remaining taco seasoning. Once the eggs have been fully beaten stir in the shredded cheese.
  • Stir in the salsa. Once the chorizo has been cooked and drained, add it to the egg mixture.
  • Pour the chorizo/egg mixture over the hash browns in the baking pan.
  • Bake, uncovered, for about 40 minutes, or until the egg center has cooked through.
  • Allow the casserole to cool and set for about 10 minutes before serving.

Notes

Recipe Tips.
  • To use fresh potatoes, peel and shred 20 ounces of russet potatoes. Blanch, drain, and pat dry before adding to the recipe.
  • You can use store-bought chorizo or make delicious homemade chorizo.
  • Top each slice with diced avocado, tomatoes, or salsa, or spoon some casserole into a flour tortilla.
Make ahead of time. Cover and keep in the fridge for up to 24 hours, or wrap with plastic wrap and aluminum foil and freeze for up to 3 months. Thaw overnight in the fridge and allow it to sit on the counter while the oven preheats. 
How to store. Divide leftovers into individual-sized servings and store in the fridge for 2-3 days or in the freezer for up to 3 months. Reheat in the microwave.
