I’m looking forward to giving this recipe a try but I’m wondering what size crock pot to use? As I only have a 4 quart & not sure it’s big enough?
This is a family favorite! We all love it.
It makes sense to put the wet ingredients in the crockpot first, stir, then add the potatoes, onions and sausage. You don’t need to dirty a separate bowl.
This is one of my go-to dinners. It’s simple and yummy.
I use closer to one cup of sour cream cause I like it creamier.
Easy to make gluten free with gluten free cream of mushroom soup (Walmart makes a good one).
I also like to mix up the shredded cheese, like pepper jack.
Did you serve it with anything else
What an easy dump and go dinner. I used leftover chopped onion from tacos the day before, and shredded hash browns turned it great on high for 2.5 hours, low for 1.5 hours.. I topped with the shredded cheese the last 1.5 hours. I also added about a half cup of milk to thin the sauce out and, of course, onion and garlic powder, my picky husband even said it was good!
Although this had great flavor, I had a few problems. I used frozen hash browns and they cooked pretty quickly. I cooked on low and the potatoes were done in about 4 hours. Also, I used 1/2 cup of sour cream and everything was pretty mushy. I think the milk would have been better.
Can you bake this in the oven instead of using a slow cooker?
yes
Temp? Time? My crockpot doesn’t seem to hold enough to feed everyone. My family loves it!
I am preparing everything tonight but I’m out of onions and I’m going to use chives. Whish me luck and I’ll let you know how tomorrow’s dinner turns out
Made as instructed but it was a bit soupy and bland. Not a dish I’d make again.
I used shredded hash browns. Will that be okay?
Yes, but you should probably shorten the cooking time.
I have made this so many times and my family absolutely loves it. I definitely add spices like I would to any dish that doesn’t call for any. Just garlic and onion powder and some cayenne pepper for a little heat. For anyone saying it’s mushy, I’d say cook on low, I tried it on high once and it was mushy. Also, don’t stir it while it’s cooking. Once everything is coated to start, just leave it alone. It comes out perfect
Comfort meal! I used frozen and it didn’t need more time. I actually turned it to low because it was cooking to fast. Easy to make! Loved by my family!
We made this with cream of chicken instead of cream of mushroom and added in the Outback Steakhouse Rattlesnake bites seasoning and it turned out SO amazing! I’m usually very picky so I was afraid to try it but even my 17 month old loved this! Will be adding to our dinner rotation list, thanks for sharing!
Everything was mush!
Can’t use my crock pot for this!
Too long to cook!
If using fresh diced potatoes, how many baby reds should I use?
Made this and tweaked it to our liking. I used cheese smoked sausage and cream of chicken with herbs. Also a blend of cheeses that were opened then topped with mac and cheese. The big saver was using generic frozen O’Brien potatoes..already had onions and peppers in it. It was really good. Also used my crock pot silicone liner …i started on high then went to low the last hour or so and I sprayed my liner too. Big difference. I didnt measure the sour cream just added 3 huge serving spoon cup is. Really good and easy when you have homework to do that you forgot about til today! 🙄🤣😁
My only complaint is the amount of ads on this page, it was so frustrating when trying to read the recipe/instructions! The page kept resetting and scrolling all the way to the top of the page. Recipe is great, easy comfort food!
The hash brown Patty’s?
No, the frozen diced potatoes.
Is there a good substitute for the potatoes if my son is allergic to potatoes?
You could sub rice or sweet potatoes? Maybe cauliflower?
Turnips or daikon radish are common low-carb substitutes for potatoes.
Taste was good but cooking time needs way adjusted! 4 hours on low is PLENTY or else you’ll have mashed potato casserole.
This was delicious!!!
This was a hit! And sooo easy to put together. I sautéed the onion and Sausage in my instant pot for a few minutes before combining everything. I used frozen potatoes and slow cooker setting on my instant pot. We felt it was done at about 2.5 hours.
Not a fan. Very cheesy, but that’s about it.
Not impressed. Cooked it on the low setting for recommended time and my keilbasa tasted overcooked with a weird texture, if i make it again i might just wait till the last hour or two to add the sausage.
Has anyone tried freezing this? I’m collecting freezer recipes to make ahead to prepare for our first born <3
I use a bag of potatoes o’brein, it has onions and peppers in it. I have also used diced leftover ham too instead of sausage. My family absolutely loves this recipe! So easy!
If I double the recipe, do I need to add cooking time?
I wish your website wouldn’t keep refreshing or you hold button at the recipe.
It doesn’t on desktop, but on mobile, that’s the ads loading and so after a few seconds it will top. I’ll look into it thanks.
Is the serving size really 1g??
Can you use all beef hot dogs instead of sausage?
Sure, but it will change the flavor.
This was easy and delicious! Thank you for sharing!
I recently tried a slow cooker sausage and potato casserole recipe, and it was absolutely delicious! The combination of savory sausage with hearty potatoes cooked to perfection in the slow cooker made for a comforting and satisfying meal. What I love about slow cooker recipes like this is the ease of preparation and the wonderful flavors that develop over the cooking time. It’s a fantastic meal for busy weeknights or a cozy weekend dinner. Can’t wait to make it again!
I added crumbled bacon, was absolutely delicious!!!
