Step-by-Step Instructions
- Preheat oven to 350°F. Lightly grease an 11- x 7-inch baking pan.
- Prepare potatoes according to package directions, adding 1/2 teaspoon salt and 1/4 teaspoon pepper. Stir in eggs, cream cheese, and onion; fold in pimiento. Spread mixture into the prepared 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.
