 If you love a good creamy cheesy potato casserole, you have to try this recipe’s tasty twist. Using French onion dip in place of the sour cream adds another layer of flavor to this already tasty side dish.

Cheesy potato casserole is always a hit. It’s one of those side dishes that goes with everything and the whole family is happy to see it on the dinner table.

This recipe has a small twist that makes it extra tasty. Sometimes it’s that one secret ingredient that makes all of the difference! 

 What do you call this dish? You know the one that has cheese and hash browns topped with buttery cornflake crumbs.

My family has always called it cheesy potato casserole. However the name funeral potatoes seems to be popular on the internet.

No matter what you call it, the dish is popular for a reason. It is creamy, cheesy, warm and fabulous. 

We tend to save it for holidays and special occasions, but it feels like it could go with almost any entrée. Everyone’s eyes get bigger and tummies get fuller when it’s on the menu.

I found a fun recipe for something similar over on South Your Mouth. She has a recipe for hashbrown casserole that uses French onion dip instead of sour cream.

The rest of the recipe is quite different than our version of cheesy potatoes. So I thought it would be fun to try her twist on our recipe. 

Of course it was amazing. All of that added flavor from the dip adds great depth to the final dish.

Sometimes it is a small change like this that makes all of the difference. It’s not a smack in the face, just a subtle something different that perks you up. 

More easy ways to switch up your cheesy potatoes

You could very easily make another simple change and use ranch dip instead of the French onion. Then you’d have cheesy ranch potatoes and I am sure that will be a hit as well.

Another easy way to change it up is to change the style of hash browns.  I like it with the southern style little cubes of potatoes.

You can also use the shredded potatoes.  Or change it up even more and use the O’Brien potatoes with bits of pepper and onion in it. 

There are so many little variations you could try to make it your own best dish ever.  Then tell me all about it in the comments so I can make them your way too!

Why are they called funeral potatoes?

In some parts of the country, this cheesy potatoes are known as funeral potatoes. That is because this comforting casserole is often served as a side dish at after funeral luncheons. In our region, they are popular at holiday meals and large gatherings of all types.

More fabulous comforting side dishes

No boil macaroni and cheese is another great cheesy side dish. You get the rich goodness without having to boil the pasta first. 

Cheesy cabbage casserole is another fun twist on a cheesy side dish. It sounds strange, but it is a super tasty recipe that just may convert cabbage haters.

Try a yummy onion casserole for something different. It has soft onions, yummy cheese and a buttery topping for a one of a kind side.

Or for another twist on a classic potato dish, try cheddar bacon ranch potato salad. It’s another great recipe that is a fun departure from a classic recipe.
