Tips & Substitutions

For a creamier texture, consider using cream cheese instead of sour cream. If you prefer a little spice, add some diced jalapeños or a dash of hot sauce to the mixture. You can also substitute the hash browns with fresh potatoes, just be sure to parboil them first. To save time, use pre-chopped onions or even frozen diced onions.

Serving Suggestions

This potato casserole is a hearty dish that pairs beautifully with Oven Fried Chicken Breast (Very Low Fat) and a fresh green salad. Serve it alongside Orange Fluffy Salad for a delightful contrast in flavors. It can also be enjoyed as a comforting breakfast dish topped with a fried egg.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place the casserole in a preheated oven at 350°F for about 25-30 minutes, or until heated through. If you want to keep the topping crispy, add fresh potato chips just before serving.
