Soup isn’t just for wintertime. I love a great soup with fresh veggies from the garden this time of year.

What I love most about this soup, is the unique flavor the tarragon adds. It’s so delicious. If you are not on a keto diet, that is okay too! I have several options for other alternative additions you can add or take out!

The other thing I love is that the whole dish of low-carb vegetables can be made in just under thirty minutes.

Are you familiar with leeks?

Deciphering the differences between the different types of onions can be daunting. There must be at least 20 different types of onions. For today, before we get started with my leek recipe, I am going to share with you just a few clarifications on the various types of sweet onions.

Deciphering the difference between onions

Green onions, spring onions, and scallions are all about the same. Each one has a sweet flavor, with some being milder than others. Then you have shallots. See what I mean, there are already four types and I’ve only just touched the surface. Leeks on the other hand are a bit different for several reasons. 

Green onions & Spring onions

First, green onions have a sharper flavor and are a great option for cooking. Next, are spring onions. Spring onions are basically green onions but have a round white bulb on the end. If spring onions are not picked they will grow into a larger onion. 


One of my favorite simple ingredients to add are scallions. Scallions are slim in size, with a small narrow bulb, and are sold in bunches. Scallions may be added to everything from omelets to salads, soups, and main dishes. I always have a bunch of scallions in my refrigerator.


Up next, we have leeks. Leeks are more cylinder in shape and have longer end bulbs.  Leeks are not considered to be a root vegetable, although green or spring onions are considered root vegetables. Green onions will have a stronger flavor than their leek counterpart.

What I love most is that leeks add a mild flavor to dishes.

Can you have leek on keto?

While leeks can pack in with carbs, the small amount you’ll use in this tasty keto soup is lower in carb content. So yes, you may have leeks on a keto diet plan. In fact, this superfood is high in Vitamin A, Vitamin E, and Vitamin K, along with a high level of flavonoids. 

Are Leeks low carb?

Being on the lower end of low-carb foods, leeks will have about 14.5g per 100 grams. You can consider leeks to be low carb and a great choice for healthy weight loss.
