What's the Difference between Leeks and Shallots?

Leeks, onions, and shallots are all often confused with each other. You need both leeks and shallots for this recipe.

Shallots look a lot of heads of garlic. Leeks look like extra large green onions.

You can use garlic in this recipe instead of shallots. But keep in mind that if you do, it will have a stronger garlic flavor.

Leeks have a milder taste than green onions. And are much longer and wider. They look like big green stalks.

How to Make Cauliflower and Leek Soup

Making cauliflower and leek soup is rather quite simple.

It's one of our easiest keto recipes that we've made.

You can find the detailed instructions in the printable recipe card at the bottom of this post. But first here's an overview of the recipe along with more helpful information too.

Step #1 Roast the Cauliflower and Shallots

The first step is to remove the green leaves from the bottom of the head of cauliflower.

Then cut the cauliflower into florets.

Toss the florets, along with the sliced shallots, in avocado oil and roast at 400°F for 30 minutes until the florets are golden brown.

Step #2 Fry the Bacon

While the cauliflower is roasting, fry up the bacon in a skillet.

When the bacon is finished cooking, transfer the slices to a paper towel lined plate.  When they are cool, you will crumble them and use them as a garnish for your soup.

Make sure to reserve 3 tablespoons of the bacon fat to use in the next step.

Step #3 Saute the Leeks

You are going to want to clean your leeks well before cooking them. Dirt collects in between the layers, so it is important to get it all out.

Prepare the leeks by trimming off the stems and cutting off the coarse dark green parts. Discard those.

Slice the leeks thinly and then put them in a colander to rinse then dry them with paper towels. Now they are ready to be added to the stock pot.

Saute the leeks in the stock pot with the reserved bacon fat.  Oh, this part smells divine!

You want to use a large pot because this is the same pot you'll make the entire soup in.

Step #4 Add Everything to the Pot

Add the chicken bone broth, heavy cream, cream cheese, apple cider vinegar, salt and roasted cauliflower and shallots to the pot.

Allow the mixture to simmer for 20 minutes.

Now you are ready to make it creamy. Use an immersion blender blend it all together.

If you don't have an immersion blender, you can put the soup, in batches, in a stand-alone blender and puree it.

Top with the bacon crumbles and you are ready to eat!
