This cozy dish of tender potatoes, cheesy with sharp Cheddar and rich with sour cream, easily feeds a crowd for brunch or a holiday potluck. Store-bought frozen hash browns do most of the work here, but you also can use frozen cubed potatoes. Traditionally, this casserole, also known as “funeral potatoes”, is made with canned cream of chicken soup, but this version calls for making the soup from scratch. While that may sound fussy, the homemade soup comes together in less than 10 minutes — and of course you can use a 10-ounce can of soup instead. For extra crunch, be sure to try the optional cornflakes topping.

Preparation

  1. Step 1

    Prepare the casserole: Remove the frozen hash browns from the freezer and set aside. Heat the oven to 350 degrees with the rack in the center position.

  2. Step 2

    Prepare the cream of chicken soup: In a medium saucepan, melt 3 tablespoons butter over medium. Whisk in 2 tablespoons flour until smooth; repeat with the remaining 2 tablespoons flour. Continuously whisk the butter-flour mixture (known as roux) to cook off the raw scent of the flour, about 1 minute. Slowly pour in the milk, whisking continuously, until thickened, about 1 minute. Slowly pour in the chicken stock, whisking continuously. Add ½ teaspoon salt, ½ teaspoon black pepper, the onion powder, garlic powder and celery salt. Stir continuously, until thickened and the mixture coats the back of a spoon, about 3 minutes. Remove from the heat, taste and adjust seasonings. Set aside to cool slightly.

  3. Step 3

    Melt the remaining 8 tablespoons of butter. Grease the bottom of a 9-by-13-inch casserole dish with about 2 tablespoons of the melted butter, swirling it around.

  4. Step 4

    To a large bowl, add the rest of the butter, the homemade cream of chicken soup and sour cream and whisk to mix. Add the onion, Parmesan (if using) and two-thirds of the Cheddar. Stir and season with 1 teaspoon each salt and pepper. Add the hash browns, gently breaking them up by hand if they’re still frozen in a solid block. Stir until everything is well combined.

  5. Step 5

    Add the hash brown mixture to the casserole dish, spread evenly and top with the remaining Cheddar.

  6. Step 6

    Prepare the topping (if using): Toss the crushed cornflakes with the butter and sprinkle on top of the casserole.

  7. Step 7

    Bake the casserole uncovered until bubbling at the bottom and beginning to crisp and brown around the edges, about 1 hour. If the optional topping browns too quickly, tent the top with foil. Let sit for 10 minutes, then garnish with parsley if you’d like and serve.

Tips
  • To make ahead, cool the baked casserole to room temperature, then cover tightly and refrigerate for up to 3 days or freeze for up to 3 months. Reheat uncovered in a 350-degree oven until warmed through and bubbly.
  • You can substitute 1 cup of shredded mozzarella for 1 cup of Cheddar.

Cooking Notes

This has been my kids favourite holiday dish for 25 years, after I got the recipe from my mother in law. I recently discovered omitting the salt and onions and adding a package of dry onion soup mix makes this even better. We’re vegetarian so we use cans of mushroom soup instead of the chicken. The beauty of the dish is how quickly it comes together, so while the homemade canned soup sounds interesting, I think I’ll stick with the canned. It’s a once a year thing.

I grew up eating (and loving) this with baked ham every Christmas. I made this recipe last weekend to see if it was just as good. Reader, IT IS. And I may have eaten 1/3 of it by myself.

I've made this, but use canned cheddar soup instead of cream of chicken, plus the sour cream and copious amounts of cheddar cheese, sometimes adding ham. Everyone always loves it, and you can top it with anything. One time I used crushed sour cream chips. I will say it usually takes about 1 1/2 to 2 hours to get it where I like it.

Frozen hash browns get a bad rep. I had the best, I mean The Best potato latkes at Fox's deli in Rochester, NY and when my SIL and I asked for the recipe, the long time owners told us they start with frozen hash browns. We tweaked it a bit and now they are the basis for our Chanukah staple. Don't knock it til you try it.

I use either canned cream of potato or cheddar cheese soup and cut down drastically on the butter and sour cream and cheese. (And believe me when I tell you I am not “that person”!) But even for me, 11 tablespoons of butter is a bridge too far, even when a lot of it is used making the soup. I use a cup of sour cream and one 8-oz package of shredded sharp cheddar. And always the cornflake topping! It’s still absolutely delicious - just not as over the top and gloppy.

I ALWAYS make these hash brown recipes with Idahoan dehydrated hash browns. Boil water, pour into the 8 oz milk carton the dehydrated spuds come in and let set for 8-10 minutes. Pour into a large mixing bowl and add all the other ingredients. These dehydrated spuds beat the frozen ones hands down. They take up less space and can be used when camping and cooked in a 3 legged Dutch oven. You can find them ( the dehydrated spud) at Costco and probably at Albertsons, or in any grocer with bulk buns.

Where is the bacon?

Never feel guilty about taking kitchen shortcuts. Some people get a little full of themselves by what they consider homemade or from scratch, like--gasp--subbing frozen hashbrowns for raw potatoes. My comeback is that these "purists" aren't digging up potatoes in their garden, churning butter, or making their own cheese. Especially if you have a hectic life or health issues, be proud of yourself for getting a home-cooked meal on the table, no matter how many shortcuts it took.

This has been a family favorite for years. The only variation is we top it with crunchy fried onion rings - store bought.

Canned soup works fine, but frozen hash browns? No, thank you. Gently boil about 6 russet potatoes until barely done. Shred after peeling or don’t peel and shred anyway. Sharp cheddar works well. This holiday dish has been known to appear in summer when a family member returns home for a visit. Great with grilled flank steak!

Very easy and pretty good for what I thought was going to be a fairly trashy dish. Obviously you could swap out the cheddar for a different cheese and get a totally different dish— say Gruyère and less sour cream. Great steakhouse-style side dish.

A version of this dish, with the addition of a pound of bulk sausage, is my family’s Christmas breakfast. Here in the deep South, grocery stores run short on frozen hash browns early in the season. We’ve discovered that frozen Tater Tots work just fine.

I make this dish from memory as the recipe got lost. We know it as heavenly potatoes and it is a stape to our holiday meals. I use boiled potatoes that are cooled and grated. Frozen hash browns work but not the same result.

I grew up eating a version of this dish. We called it 'Texas Casserole'. There was no parmesan or extra seasonings, but my mom would make it with a can of Campbell's cream of chicken soup, frozen hash browns, sour cream, cheddar, chopped white onion, and a buttery cornflake topping. I always enjoyed the bits of undercooked onion throughout the dish, and obviously we all fought over the crispy edges. Although we seldom ate processed foods growing up, this was always a favourite.

I dislike the bland sameness of color in this casserole, so I add the chopped greens from a large bunch of scallions to the potatoes before baking, and sprinkle chopped chives over the top before serving. The onions add a nice sharp bite & an oomph of extra flavor. I've also added diced ham on occasion to turn this into a dinner casserole & serve with a salad for a complete meal.

You’ll never go back! For those who grew up with the recipe using canned soup, this is way better. WELL worth the few minutes to make the roux. Recommend using crushed Ritz crackers instead of corn flakes for the topping. Also can use slightly less butter in the potato mixture. Overall though, this is wonderful.

This turned out great. Used 2 tablespoons less butter, decreased the salt slightly, and skipped the celery salt. I used 1/2 small onion (not a whole one). Used breadcrumbs as the topping. While using frozen hashbrowns worked great and was convenient, they are so very expensive compared to fresh potatoes. I'd like to try this again using fresh potatoes, as in my opinion it's not really very practical to make it often with the exorbitant price of frozen hashbrowns at my nearby supermarket.

Big hit at the brunch table! Very easy to make. I made it the day before, because the oven was going to be occupied, and it reheated beautifully.

Add a lb of cooked breakfast sausage to this casserole and serve with scrambled eggs! This is a family brunch tradition for every holiday we celebrate when we all get together. Everybody looks forward to it. We call it Breakfast casserole. You could add chopped ham or bacon instead but the meat is a nice addition.

Made for Easter 2024. Served 10. Could use less butter.

Do fewer onions and cook them down first

Joe’s Potatoes! Made for Easter 2024. Yummy

I would cook it longer than the recipe calls for. I did make the soup (but using vegetable stock), and it turned out well. It would be easier to just buy a can of soup, however, if additives in the soup are not a concern. I used half a large onion, and that was a bit too much for my taste. Other than cooking it longer, it turned out well and was a hit at my potluck!

Well loved by everyone for Easter dinner. Went well with ham. Followed recipe exactly

Try Panko Breadcrumbs in place of cornflakes.

You can make this ahead and freeze it before baking. I often make the whole recipe and put in smaller dishes, which have enough for 2 people, and put them in the freezer. I do not put the cornflakes/butter on the casserole before freezing, instead put them in a plastic bag, and then put on top of the casserole before freezing, adding it before baking. Thaw before baking or add 20-30 minutes to the baking. I use cream of celery most of the time.

I think this does a bit better if the hash browns are thawed before warming. I have made this with the canned cream of chicken soup as well; it is not as flavorful and is more salty

Made this by the recipe and also made a vegan version with substituted vegan cream cheese, milk, and cheddar. Both vegetarian and vegan versions turned out well. Will make this again, but will add some frozen vegetables.

This came together so easy and is so good! I can’t wait to have an event to bring this to so I have another reason to make it. Will def become a holiday favorite, but it’s easy enough to make anytime! Next time I will decrease the salt by half. Or just not add in the 2t at the end. Was edible and delish but too salty. I didn’t have any stock on hand like I thought I did so I just doubled the milk. Would be easy to make gf with a gf flour replacer in the roux instead.

This is really good but to make it better confuse half an 8 oxthing of light sourcream
