Have you tried it?

Yeah, me neither!

But every time I go to the store, I tell myself that I need to make tomato feta soup.

Creamy tomato soup is one of my all time favorites.

Forget the grilled cheese, I can have it on its own or occasionally accompany it with some freshly baked crusty bread.

This Easy Tomato Feta Soup Recipe is bursting with Mediterranean flavors.

I like to add a little pesto sauce to my tomato soups, but this time I just used fresh basil.

I also seasoned the soup with oregano, which pairs perfectly with the feta cheese added at the end.

Since the tomatoes are slightly tangy as well, I recommend adding a little bit of sweetener to the soup to balance the taste.

For those of you on a Ketogenic diet (which I currently an on), I’d suggest that you use erythritol, for everyone else white granulated sugar or some honey will work.

We are talking about 1/2 tsp erythritol, sugar or honey.

What does adding feta cheese do to the flavors in this soup?

Adding crumbled feta cheese to this soup adds saltiness and also tanginess.

It definitely adds creaminess and texture, but it also doesn’t melt.

All ingredients necessary for this creamy tomato feta soup recipe are :

Fresh or canned tomatoes?

I’ve given options in the recipe.

I’m aware that canned tomatoes are just so easy to use!

But if you have fresh tomatoes and don’t mind peeling them, I’d prefer these for this Mediterranean tomato feta soup.

Fresh or dried herbs?

Fresh herbs are perfect if you have them.

Dried herbs works great as well!

This recipe is also great for people on a moderate Ketogenic diet, since tomatoes aren’t too high in carbs.

All other ingredients on this soup also are low in carbs and pretty healthy!

  1. This was such a good recipe! I’m a little confused on how 6 cups of soup come out as I only got 3 cups. The only item I omitted was the heavy cream as I substituted it with cream cheese but that was only 1/3 cup. Any idea where I may have messed up? I used Roma Tomatoes for this recipe.
