I’m curious what you all eat for the holidays? Typically our meal is a carb overload. Of course we have the ham (or turkey for thanksgiving)…but then you have mashed potatoes, sweet potatoes,  and hashbrowns. Oh and a basket of dinner rolls is a must too!

This Cheesy Hashbrown Casserole has been making appearances at family functions since I was young. You know, back when Corn Flakes cereal was like one of only 20 cereal choices. And as children, we liked Corn Flakes! I have to be honest, my kids don’t care for Corn Flakes (they much prefer frosted flakes). The only time we have a box of Corn Flakes in our pantry is when I know this hashbrown casserole is going to be on the menu!

Cheesy Hashbrown Casserole recipe with cornflake topping

My mom’s recipe uses shredded cheddar cheese. You know, the orange stuff in the bag (which we all love of course). However, if you’re looking to take this to the next level of deliciousness, try using Cabot Seriously Sharp Cheddar. It gives this dish such an intense, tangy flavor you can’t resist. And, it melts so creamy mixed up with the rest of the ingredients!

It’s such a great addition to any meal as it can be prepared ahead of time. All you need to do is pop it in the oven when it’s time to cook the meal. I hope you enjoy this as much as my family does!

How to make Cheesy Hashbrown Casserole (or funeral potatoes):

  • In a big bowl, you’ll mix everything together. It’s okay if your hashbrown potatoes are frozen. My family prefers the “cubed” version, but if you like shredded feel free to use those!
  • Crush your cornflakes slightly, you don’t want tiny crumbs here, but you also don’t want all whole flakes either. Mix up your corn flakes with the melted butter and sprinkle it over the top of the casserole.
  • Cover with foil and bake. Until bubbly. About one hour. SERVE hot!
  • This makes delicious leftovers too, so be sure to save it!

  1. Looks so good and well balanced in ingredients! Perfectly simple side dish with almost anything!

  2. Heart eye emoji! Crunchy, cheesy, casserole of my dreams. Especially since you used sharp cheddar. 

  3. My family has a very similar version of this recipe, and I posted it this week too, coincidentally! My Grandma found the recipe somewhere, and we’ve been making it for holidays ever since. Love how simple it is, and how ultra-cheesy! It’s definitely a crowd-pleaser. Looks FABULOUS!

  4. What?! Hashbrown casserole? This looks insane! I love hashbrowns but have never seen anything like this before 🙂 Yum!

    How funny, made a dish like this tonight. Recipe quite similar, but, had to do some subs, as the hubs bought the cubed hash browns instead of the grated. Then we had no corn flakes, but I did have corn flake crumbs. So combined 2cups crumbs with 1/4 cup melted butter. Put that on top. Oh, and was too lazy to grate more cheese,so used up the combined cheddar and Monterey Jack had shredded the day before. Was still pretty good and we are all blobbed out from the meal!!!! 

  6. Ohmygosh crispy creamy cheesy heaven! I need the entire casserole dish for my face! <3 I love that it's make ahead too!

  7. Mmmm this is such a delicious idea… Would it be bad to make it for Thanksgiving breakfast??? 🙂

  8. Yum! Nothing quite as comforting as cheese and carbs!

  9. this is sweet Casserole and super easy, I should share, great thanks

  10. This casserole would disappear in a hurry at our house! This is some great comfort food!

  11. Yum!!!  I love this potato casserole too!!!! This is very similar to the cheesy potatoes we have been making forever too.  I just assumed everyone had this recipe, so I have never posted it.  LOL! I should know better and just post whatever we eat whenever, right?

  12. classic, delicious, indulgent comfort food!!!

    Best recipe ever!!!!! I’ve been making this for years. I got the recipe from my mom who always made it. My daughter LOVES this…she expects this to be made at any gathering. lol. I use shredded instead of cubed hash browns, and usually add in more sharp cheddar to make it cheesier(and because my daughter and i love sharp cheese). 🙂 I also use just about the amount of minced onion you have listed, versus what my recipe calls for… 1/2 cup chopped onion. I am not a onion person so cut back & use minced. I’m asked often for this recipe…including my husbands 93 yr old grandma who mailed me a recipe card wanting it! lol.  It freezes well, because I usually make 4 or 5 batches of it before summer to put in freezer so I can pull it out to throw in oven at anytime. Then I don’t have to worry if I have all the ingredients! 🙂
