Notes

You may want to saute the onion and sausage before adding to the slow cooker.
If you substitute fresh diced potatoes for the frozen, you will probably need to add to the cooking time. The dish is done once your potatoes and onions are cooked.
The original recipe called for 1/2 cup milk, but many people said that it turned out too runny, so I changed it to 1/2 cup sour cream instead.

    1. I have not, but I'm sure it would work, especially if you used regular potatoes and sauteed the sausage outside of the Instant Pot and mixed them in at the end. That's how I would prepare it.
    2. Did you try this in the instant pot? I am hoping to experiment with this recipe in my instant pot but was curious if you tried and have a recommended cook time!
  1. I tried this today but my potatoes didnโ€™t cook all the way through. I small diced them and started it on low for 4 1/2 hours and switched to high for 1 1/2 hours. They are still a little to crunchy for me. Also itโ€™s like a soup, maybe the consistency will turn to a creamy, Iโ€™m not sure. Anyways Iโ€™d recommend cooking longer for diced potatoes.
  2. This was delicious! Would you be able to tell me a serving size ... 1 cup? I know serves 6 but was uncertain for calorie counting:) Thank you!
  3. Ok... So I was on the phone๐Ÿ˜ฌ while getting things ready send I mixed everything before placing in crock pot! ๐Ÿ˜ฌ Iโ€™m cooking on high for 3-4 hours. Do u think it will cook right??
  4. It was very soupy and lacked flavor. The kids wouldn't eat it and I didn't like it either. Followed the recipe to a T. I was hoping it would be like your pictures, but it was like a thick, mushy soup.

    1. I'm sorry that the recipe didn't work out for you. I'm assuming the potatoes were overcooked and that's why it turned to mush. I haven't had this happen, but lowering the cooking time should fix that. Some slow cookers are hotter than others.
  5. I used velveeta cheese and it curdled some. I think if I cook this again I will just shred some cheese.
    1. Yes, I bet the would work well, you will have to adjust the cooking time though. Not sure if cauliflower and potatoes have the same cooking time. They would probably be similar.
  6. Do you think I could use a regular oven for this recipe? If so how long do you think I should cook it for? Also I plan on using Frozen diced potatoes. TIA
  7. I love how cheesy this recipe is and potatoes and sausage together... perfect! The seasoning is really lacking for me. I use onion powder because I do not like onions. The onion to me is not the right flavor to go with this. I feel like it needs different seasoning but I can not figure out what else to use that would elevate this.
  8. I was wondering if you could add a can of cheddar cheese sauce with the cream of mushroom/chicken?
  9. I substituted fresh diced potatoes (about 2lbs) for the frozen potatoes. Also, I added a can of cheddar cheese soup. Cooked on high for 4 hours to make sure potatoes were cooked. Delicious!!

  10. This recipe was really easy to throw together! I think it was a touch bland, so I think next time Iโ€™ll use sharp cheddar cheese, a little more onion, salt, and pepper, and perhaps a hint of red pepper. Thanks for this great, easily adaptable recipe!

    1. You could always make your own cream sauce using equal parts butter and flour and 2 cups of milk or you could try sour cream mixed with some milk to make it runny. I have no idea how that would work out though.
  11. I just made this and it was so good. My 4 year old little boy had two full bowls full. Very hearty. I used smoked sausage and cut up the potatoes small and cooked it on high for 4 hours. Make sure you stir often after the first 2 hours so the potatoes dont scorch. Very delicious!! Thank you for sharing.

  12. LOVED it the first time i made it. The family ate it all. This time I forgot to mix the milk and soup together before putting it in the crock pot do you think it will turn out, or should I come up with a different plan for dinner? ๐Ÿ˜ฉ
