What I like about cooking the most is you get to control everything about it. You can add more of this and less of that depending on your taste.
Like more heat? Add more spice
Do you really like cheese? Add more cheese.
Donโt likeย butter? Ah, Donโt addย butter!
I developed this recipe because Iโm not a big fan of โcream of anythingโ soup. It has too much sodium!

Do you I thaw the potatoes
You can do it either way. Mine were frozen as noted in step 2
Made this yesterday to RAVE reviews! This is the tastiest, yet most simple recipe ever. Thank you for sharing this recipe with us.
so happy you liked it!
I love how this recipe doesnโt use cream of whatever! Thank you so much for this recipe! It turned out perfect, and it was a tasty side dish!
Thank you! I’m happy you enjoyed it
Canโt wait to try this! Iโm making it today and my hash browns were in the fridge overnight so they arenโt frozen. Is that okay?
Yes, that will work wonderfully
Can I use half and half in place of the heavy cream?
yes
Thanks Paula, I figured, but just wanted to check so I wouldn’t end up with something mushy.
Hi,
Can I use evaporated milk? I’m staying in today and do not want to go to the store for heavy cream.
If you use evaporated milk, add 2 to 3 tablespoons melted butter.
Could I sub heavy cream for cream cheese.
could you substitute refrigerated simply potato hash browns in this recipe ? I imagine the baking time would be different?
Aren’t those the best? Yes, you can sub those. It should take a total of 45 minutes to cook.
I have these in the oven now for a test run for a bridesmaids brunch coming up. Kitchen smells heavenly. Have u ever made these in the slow cooker? Using the refrigerated hash brown version? Would save me some time and would keep them warm. Any time suggestions? Thanks!
I just made a different hashbrown recipe in the slow cooker and it took 4 hours on high for the potatoes to cook. For the 3 Ingredient Hash Brown Casserole, you will probably need to add more whipping cream. It take up to 1 cup more.
So yummy. Added fresh thyme and used parboiled shredded potatoes– the house smells heavenly.
OMG, how simple can hash brown casserole get? This is an absolute favorite! I make this in four 16 ounce corningware ramekins and freeze. Sometimes I sprinkle the top with seasoned Italian bread crumbs. I pull a ramekin out of the freezer, thaw and heat in the microwave. Easy side dish for two! Hubby enjoys it for breakfast as well.
Thanks for a great can free soup recipe.
Thank you! I am also not a fan of cream of soups! The hashbrowns are now baking in the over and they smell wonderful
Hope you enjoy it!
