Notes
From Our Test Kitchen
The biggest difference in this recipe is whether you start with frozen or thawed hash browns. Frozen potatoes release extra moisture as they cook, so they need the longer baking time before removing the foil. I also like to stir the soup mixture into the potatoes just a little instead of leaving it sitting on top. It helps coat everything evenly, so every bite comes out creamy. The Parmesan goes on during the last 15 minutes. That keeps it from disappearing into the casserole and gives the top a lightly golden finish with extra flavor. If using frozen hash browns, bake the covered casserole for about 1 hour 30 minutes before adding the Parmesan and baking uncovered for the additional 15 minutes.Use Cream of Anything Soup Mix

Make-Ahead Tips
This is one of my favorite casseroles to assemble ahead of time.
- Assemble everything except the Parmesan cheese.
- Cover and refrigerate for up to 24 hours.
- Bake as directed, adding a few extra minutes if the casserole is going into the oven straight from the refrigerator.
- Sprinkle on the Parmesan during the final 15 minutes.
Easy Variations

Ham: Fold in diced leftover ham to turn it into a heartier meal.

- Baked ham

Storage and Reheating
Store leftovers in an airtight container in the refrigerator for 3 to 4 days.
Reheat individual servings in the microwave, or warm the casserole in a 350°F oven until heated through.
You can also freeze baked portions for up to 2 months. Thaw overnight in the refrigerator before reheating.
Can I use frozen hash browns without thawing them?
Yes. Bake the covered casserole for about 1 hour 30 minutes before adding the Parmesan and baking uncovered.
Can I substitute a different soup?
Absolutely. Cream of mushroom or cream of celery both work well if that’s what you have in the pantry.
Why is my casserole watery?
Frozen hash browns naturally release moisture as they cook. Giving the casserole enough covered baking time and letting it rest for 5 to 10 minutes before serving helps it set up nicely.
Can I double this recipe?
Yes. Make two 9×13-inch pans instead of one oversized pan so they bake evenly.
Homestead Kitchen Notes
This is the kind of recipe I keep around because it doesn’t require fancy ingredients or extra fuss. A bag of frozen hash browns, a couple of pantry soups, and a little cheese are all it takes to make a warm, comforting side dish that’s always welcome at the table.
It’s one of those dependable recipes that’s just as good for a holiday meal as it is for bringing to a friend, a church supper, or a family potluck.
