This Low-Carb Cream of Celery soup will warm you up on a cold winter’s day without the heavy carbs. It’s made up of easy refrigerator and pantry staples including butter, heavy cream, onions, celery and chicken broth. Flour is replaced with riced cauliflower straight from the freezer to give this soup some body and creaminess.
Barbara whipped this up when we got our first snowstorm of the season. She bought a bunch of celery that was close to going to the dark side. This recipe came together in less than 30 minutes, and the leftovers got better as they sat in the refrigerator. Have leftover soup? Pour leftover soup into pint-sized mason jars for easy travel to work.
We made some simple substitutions so that this soup will fit into a keto-friendly, low -carb or gluten-free diet.
Riced cauliflower is quickly becoming one of our favorite ingredients, because it is readily available at most grocery stores, including Aldi (our favorite). We use it in our Low-Carb Mexican Taco Soup, Low-Carb Tuscan Soup and Low-Carb Beef Fried Cauliflower Rice. Riced cauliflower gives soup a heartiness without the carbs.
Notes about this Low-Carb Cream of Celery Soup recipe:
- The amount of diced celery doesn’t need to be exact. The bunch that we had in our refrigerator ended up being about 6 cups.
- Don’t throw out the leafy ends of the celery. Chop them up and add them for added flavor.
- Omit onions, if desired.
- You will want to taste the soup and add more salt and black pepper to taste. Bland soup is not good!
- You can use fresh garlic that you mince yourself. I keep a jar of minced garlic or minced roasted garlic in my refrigerator at all times. Just for the sake of easiness.
- If you like a completely smooth soup, do not reserve any of the cooked veggies. On the flip side, if you like a really chunky cream soup, reserve more than the 1 to 2 cups, and add it after you puree the soup.
- Be sure to use low sodium chicken broth. If you have regular, be sure to reduce the amount of salt for the recipe.
- Use a food processor or immersion blender to puree. The soup is very hot. Put a towel over the top of the food processor. Hold down while blending. This prevents a spray out and burn.
