So tasty! However I had to add milk- it definitely needed some liquid! Not sure if my crock pot just gets too hot or if it would be better cooking on low, because I did it on high. I also added some Italian seasoning. Easy and yummy, thanks!
I added cream cheese and Italian seasoning. Still thick, but darn tasty.
Can you freeze this into portions after baking it in the oven or will it make the potatoes too mushy and watery? Maybe I should’ve frozen it before baking it? I live on my own and no way can I eat it all myself without it going bad first or me getting sick of eating it multiple days in a row.
Looking for response on this inquiry
I haven’t tried it with this recipe but I’ve frozen similar recipes and it always works out fine. I tend to find baking it before freezing better, otherwise the potatoes get black due to the moisture and oxygen mixed in with the other ingredients.
I thought this was great. My grandson loved it….had seconds for dinner and another serving later in the evening! The bag of hashbrowns I had was only 28 oz but there was quite enough potatoes. Mine wasn’t runny at all.
Is there a way to adapt this to the Instant Pot? I won’t have 6-7 hours to cook this. Thanks!!
You can cook it in a casserole dish in the oven for 30 minutes or until the potatoes are cooked through.
What temp?
What temp do you use for the oven?
350 F
Can you use smoked sausage and if baking in oven at what tempersture
Yes, 350.
Should I be adding milk with the soup or sour cream? I think there’s a slight difference in the recipe as written vs the video.
I know this is old but just came to say I tried using the slow cooker on my ip and it failed miserably for fresh cut potatoes. So this time I pressure cooked the potatoes and will slow cook the rest, but I could just as easily just warm it up or bake it.
Mines a question:
What kind of cheese can be used instead of cheddar?
Any shredded soft cheese that sounds good to you.
When using frozen diced potatoes, do you need to thaw them out first?
There is no need to thaw the potatoes.
Could you use Velveeta and shredded hash browns??
It might work, but you’d have to cook for less time and keep an eye on it.
As written..this is a great recipe! Being the adventurist type..I made an adjustment..I added 2 blackened poblano peppers (skin and seeds removed) and the residual juices to this. It was AMAZING as written..but..here in deep Texas..everything is better with peppers (of any kind)! Just took this recipe ‘one step’ over amazing!! Ty for your creation!
I love this recipe. So easy and tasty. I do bake mine in the oven though cause it scorched in my slow cooker on low.
What temp and how long?
Fantastic recipe! It was so easy and delicious. My husband and I really enjoyed it.
I made this, but with fresh cubed potatoes, and chunks of ham instead. (I don’t care for sausage) I cooked it for about 5 hours on high. It is really good, but it was a little runny!
I made this tonight and everybody loved it!! I added a mixed variety of bell peppers and seasoned the cream of chicken and sour cream with Italian, garlic herb, and black pepper seasonings. I also used local reindeer sausage (since im in alaska) fresh cut red potatoes and then topped it with green onions when it was done cooking. I also made made garlic bread to dip in it. Ill definitely be making this again! Thank you for a really good simple recipe.
This is a staple recipe in our household! LOVE IT!!
I’m using fresh potatoes for the first time because we cannot find the hashbrowns ANYWHERE! Does anybody know how many potatoes I should use for a double batch?
32 ounces = 4 cups
I am new cook so I am unsure of this…….Do you cook the sausage first? Thank you in advance.
The sausage is fully cooked, but you can saute it to give it some brown color if you would like, otherwise you can just add it in without cooking.
What is a serving size ?
Very delicious, going to be make again list definitely. Cooked in oven.
Can you use Chicken Sausage instead of kielbasa?
Yes
I made it tonight and we loved it. I’m asking for clarification on the amount of calories per serving. You listed 592 calories for 1gram serving. 1 gram is .035 ounces. 😳 Is this correct? I had 2cups and need an accurate calorie count.
The 592 is for one serving. I don’t know where the grams is coming from, so just disregard that.
Made this for dinner using smoked turkey sausage, fresh potatoes (did not need longer to cook). Subbed 1/2 cup smoked gouda for some of the cheddar and added a heaping spoonful of trader joes Dijon mustard and a splash of milk. It was delicious! And the leftovers reheat well. Serve with some hearty bread because you’re going to want to get every drop of sauce.
I couldn’t find diced potatoes ANYWHERE, and I’m really not feeling like dicing up potatoes. So (first time ever) I bought CANNED potatoes 😳 yes, I’m nervous about this. Do suggest adjusting the cooking temp/time for these?
Since canned potatoes are already cooked, I would only bake for 20 or so minutes and see if it is ready.
This is NASTY!!! What a waste of my money
Can you substitute something for sour cream?
You could use another can of cream of mushroom soup.
My 3 yr old loves broccoli. I have frozen on hand. Would it come out too soggy in the crockpot?
I mean adding the broccoli to the recipe
I think it would work out just fine.
I just made this recipe tonight and I’m not sure I’m sold on it quite yet.
What’s great about this is that you can add anything to it. A dump and go. I used everything but fresh onion. Son doesnt like onion but never can tell when its the powder and mixed with the food. Also used garlic powder and added a small can of mushrooms. Had it with sweet corn (canned and with Italian seasoning). Hope you tried it again.
This was so easy and really good. Will definitely make this again!
We loved this! Added peppers and it added a great kick to it
Did you stir it at all while it cooked??
I was wondering about oven baking this. Someone had said only 30 minutes at 350. Is that correct? I just want to confirm that before I cook it.
Thanks.
I’m hoping that’s correct because I’m trying it now 🤞🤞
For me this is a great dish to make for when you have a hangover scheduled!!! It was a breeze to make and really hit the spot when nothing sounded good. I will make this again in the future but not on a regular basis because it was a bit too much like glop.
Very good my whole family loves it. I love it because it’s quick and easy how make it every week
My husband and I made this for dinner and it is so good! So easy and simple, and the leftovers heat up well.
