Ingredients

5 servings

  • 1/4 tsp black pepper
  • 2 large eggs, lightly beaten
  • 1 package (3 oz) cream cheese, softened
  • 1 small onion, chopped
  • 1 jar (2 oz) diced pimiento, undrained
  • 1 cup (4 oz) shredded sharp Cheddar cheese

Step-by-Step Instructions

  1. Preheat oven to 350°F. Lightly grease an 11- x 7-inch baking pan.

Common Problems and Solutions

Q: Can I use fresh mashed potatoes instead of frozen?

A: Yes, substitute about 3-4 cups of freshly mashed potatoes for the frozen package. Make sure they're warm when mixing in the other ingredients so the cream cheese incorporates smoothly.

Q: Why is my casserole watery?

A: Make sure to drain any excess liquid from the pimiento jar if needed, and ensure your mashed potatoes aren't too thin. If using fresh potatoes, avoid over-mashing which can make them gluey and release starch.

Tips and Techniques

For extra flavor, sauté the chopped onion in a bit of butter until softened before adding to the potato mixture. You can also add crumbled bacon or chopped green onions as a garnish after baking.
