Roasted Cauliflower Soup- no salt, low potassium

Who knew 3 basic ingredients could taste this good?  Last week, my 82-year-old father-in-law was put on a no-salt, low-potassium diet.  This is the result of not very well regulated diabetes has had on his kidneys.  They can no longer filter out the potassium which has caused his blood pressure to plumet.  Not good.  Basically, now, everything he thought was good for him, is now not good, or must be eaten in carefully monitored portions.  Something else he’s not very good at: portion control.  He actually liked this soup,and hopefully it will satisfy the potato cravings.

  • 1 small to medium head cauliflower
  • 1 medium yellow onion, peeled and quartered
  • 1 head garlic (leave whole)
  • 2 cups water

Cut the cauliflower into pieces and place on cookie sheet.  Add the onion quarters and the whole head of garlic. 

Spread out, and bake at 375 for 45 minutes.  Check the veggies, if they are well-browned, remove them.  Check the head of garlic to see if it is squishy.  It may need another 10 to 20 minutes to roast.

Add the cauliflower and the onion to your blender, and about 1/2 of the head of roasted garlic.  Add 1 to 2 cups of water.  One cup if you want the consistency to be more like mashed potatoes; add two cups (or more) if you want a more soup-like consistency.  Puree till smooth.

If you are not on a salt-free diet, you may add a teaspoon of salt before blending.  It actually tastes pretty good without the salt.

Cream, chicken stock, and cheese may all be added, if desired, but for those who’ve just been put on a kidney diet (no salt, low potassium), this is a good replacement for potatoes.

Freezes well.

  1. This sounds great,my sister is in renal failure .I am going to make this for her!!!! Do you have any other recipes like this? Or suggestions on a good web site? Thanks

    • Yes! Cooking Light gives a full nutritional breakdown; others don’t. You just have to search for the foods they can have (red peppers, turkey, cauliflower, etc) to find new recipes with sodium and potassium content. The other website which is great for kidney patients is they identify their recipes as Chronic Kidney, Dialysis, or Diabetes, or all three. My father-in-law did call to tell me his numbers *potassium) were back in the normal range. Good luck. All they told him was what NOT to eat, and not so much what TO eat. When everything he thought was good for him, is now bad. Tough change. the website was the most helpful.

    • Okay, Lena, I went ahead and posted a red pepper marinara sauce for you. It is from the website. It’s very good, even my salt-loving mother-in-law conceded it was good (she would just add her own salt on hers! not his!) Good with from-scratch turkey meatballs on a bun, over pasta or even rice.
