How to Make Instant Potato Casserole

  1. Preheat oven to 400°F (200°C).
  2. Prepare 6 servings of instant mashed potatoes according to package directions, omitting butter.
  3. Add 4 ounces (113g) of softened cream cheese, 1 large egg, 2 tablespoons of chopped fresh parsley, and 1/4 cup of finely chopped yellow onion to the potatoes.
  4. Mix thoroughly until all ingredients are well combined and creamy.
  5. Grease a medium-sized casserole dish (approximately 8x8 inches) with butter.
  6. Pour the potato mixture into the prepared casserole dish.
  7. Dot the top with 2 tablespoons of butter, cut into small pieces.
  8. Sprinkle generously with paprika to taste (about 1/2 teaspoon to start).
  9. Bake for 30 minutes, or until golden brown and heated through. If the top is browning too quickly, loosely cover with foil.
  10. Let stand for 5-10 minutes before serving. Enjoy!
