Pin This RecipeNEW FAVORITE ALERT! We are in love with this potato casserole. I’ve made it so many times over the last few months. We just can’t get enough of it. The recipe is from Plain Chicken reader, Pam. She was given this recipe by an elderly lady at her church. She said it was delicious. I read over the recipe and was intrigued by the French Onion Dip in the casserole. Why hadn’t I thought of that?!?! I immediately added it to the menu. I am so glad that I did. It is delicious!
How to Make French Onion Potato Casserole
This potato casserole is super easy to make. Simply mix together frozen hash browns, sour cream french onion dip, cream of chicken soup, and cheddar cheese. Spread the mixture into a baking dish. Top the casserole with crushed cornflakes and butter and bake.
Tips for Making Potato Casserole
- Make sure to use a refrigerated sour cream French Onion Dip. I prefer to use Kraft French Onion Dip. I think it is the best! If you can’t find Kraft, any brand will work – Helluva Good, Dean’s, Barber’s, Great Value.
- I can’t find french onion dip. What can I use instead? If you can’t find the sour cream dip, you can substitute sour cream and a few tablespoons of onion soup mix.
- You do not need to thaw the frozen hash browns before adding them to the casserole.
- Can French Onion Potato Casserole be made in advance? Yes! You can assemble the casserole ahead of time and refrigerate it until you are ready to bake. The casserole will keep 2 to 3 days in the refrigerator.
- Can French Onion Potato Casserole be frozen? Yes! You can assemble the casserole ahead of time and freeze unbaked for later. To bake after freezing, thaw completely and bake as directed below.
- You can also freeze the baked casserole. To reheat after freezing, thaw and reheat in the microwave or in the oven. To reheat in the oven, cover with foil and bake at 350ºF until warmed through.
- This casserole is great for a crowd. It makes enough for about 8 to 10 people. Depending on what else you serving, it could easily feed 12 people. I divide the mixture between 3 foil pans and freeze them. I love being able to pull one out of the freezer for dinner.
- Is this casserole gluten-free? If you need a gluten-free casserole, use gluten-free cream of chicken soup and gluten-free cornflakes. You can substitute crushed pork rinds for the corn flakes if you can’t find gluten-free cornflakes.

Hi Stephanie:
Do use freeze it before baking or after baking? Also, how do you heat it for serving?
I freeze it unbaked. I thaw it in the refrigerator before baking and cook as instructed above.
Looks delicious. Can`t wait to try it this weekend.
Is this condensed cream of chicken soup, or regular? Thanks!
This sounds great – thanks so much for sharing
I make a breakfast casserole similar to this, with sausage in it. It is deee-licious!!! I'm a Purity French Onion Dip girl 😉
I love hashbrown casserole and will have to try this version. But living in Alabama, I will have to use Barbers Party Dip cause it is the best french onion dip.
I made it w the buffalo chicken dip last time. YUM
This is absolutely genius. How did I never think to add French onion dip to cheesy hashbrowns?!
I thought the same thing! It's so good!!
I've been making this for years, For some reason, it is best to thaw the hashbrowns overnight in the fridge! It is yummy!! 🙂
Having been to many church potluck suppers, I know those little ole ladies always have some great recipes and this sounds like one of them.
I will be trying this one soon.
