Cream of Celery Soup
I have always loved the versatility of cream of celery soup. Often used as the base for casseroles I love how you can use the soup as a sauce, or just a simple soup that is also keto and low carb.
This soup is very light and creamy! I recommend using homemade chicken broth for the recipe! It adds so much more flavour!
The Key Ingredients for Celery Soup
Keep reading for more details on the ingredients, substitutes and step by step instructions on how to make our delicious keto leek and celery soup.
Cauliflower – This celery soup without potato uses cauliflower to thicken it. Most celery soup recipes use potato. The cauliflower replaces it. Trust me, the kids won’t even know it is there!
Onions and leeks – both the onions and leek, do add carbs to this soup, but they also add loads of flavour! You can omit them completely to reduce the carbs or if you cannot eat them for allergies or just don’t enjoy them.
Celery – I use fresh celery to make this celery soup very light and creamy. You can use celeriac root if you prefer. It adds the flavour and makes the soup more hearty!
Ham Croutons – I used leftover Christmas ham for my croutons. You can swap for bacon or speck. Or any crispy croutons you prefer.
Fried celery leaves! Oh my gosh these are amazing! You need to try them with this soup! Trust me, you will never throw the leaves out again!
For a vegetarian or vegan celery soup simply swap the broth to vegetable broth. Leave out the ham croutons and don’t add the cream.
Make a big batch and enjoy it later in the week. Or freeze it celery soup freezes really well. You will have a great low carb soup to enjoy on its own or as a base for a hearty family meal.
Carrot and Celery Soup – Add 1-2 carrots (chopped) at step one.
Cream of Potato and Celery soup – swap potato for the cauliflower.
Add protein – add chicken thigh fillets at step 1 for a chicken and celery soup. Add white fish fillets after pureeing the soup and poach in the hot liquid.
How To Make Cream of Celery Soup
Step 1. Melt the butter in a Dutch oven or large saucepan over medium-high heat. Sauté the onion, leek, celery, cauliflower, and garlic until the vegetables begin to soften; 7-8 minutes.
Step 2. Add the chicken broth and bay leaf; cover and simmer for 10 minutes. Add the heavy cream; cover and simmer until the vegetables are tender, approximately 10-15 minutes.
Step 3. Remove the bay leaf and puree the soup with a stick blender or food processor for 2 minutes or until silky smooth. Season to taste.
Step 4. In a separate pan heat the avocado oil over medium-high heat and lightly fry the ham until crispy. Set aside to drain on some paper towel.
Step 5. Using the same pan fry the celery leaves until crisp. Drain the leaves on a piece of paper towel. Divide the soup between serving bowls and top with ham croutons, crème frâiche, fresh herbs, and fried celery leaves.

This soup was so velvety and smooth, absolutely delicious. I garnished with some crumbled bacon and it was heavenly. Such a warm and cozy soup.
