Delicious Tomato Soup with Butter, Red Onion & Basil


It finally feels like winter here in California. Though it rarely snows in LA, temps have dropped to around 40 at night which is quite chilly. No more walking around outside with shorts and a T-shirt. At least flip-flops are still manageable. 🙂

I’ve been playing with my new immersion blender and have a put it to good use so far. I like it a lot and it definitely beats trying to pour super hot liquids into a counter top blender.

I bought it because my old one crapped out. This KitchenAid blender came with a pot protector, which prevents the metal from scratching your non-stick surfaces. So far so good!

I don’t know if it’s worth it to pay a bit more and get a cordless one, so for now, well see how I manage with the cord.

Tomato Soup

Who doesn’t like tomato soup? Reminiscent of warm summer days, it helps me get through cold winters. As long as you don’t add salt it’s relatively healthy.

I’ve made many tomato soups over the years. In fact, last year, I discovered seriouseats 15-minute tomato soup and ate that to death. This soup may very well lead me to relapse into my tomato soup eating adventures again.

If you haven’t tried it, that’s another recipe I’d check out if you are into tomato soup like me. But start with mine first, it’s also doable in about 15 minutes ! 🙂

This soup is great as a side or as a light lunch. Maybe you can serve it with a salad or a grilled cheese. Whatever you fancy.

It only has a handful of ingredients and is a good way to warm up. The buttered onions are the base and all you really add is tomatoes, tomato paste, broth, and basil. Straightforward, not too rich, and delicious.

How do you make your tomato soups?

  1. I enjoyed the video. Reading a recipe is fine but I think the video is really helpful for a lot of people! And the soup looked amazing!

  2. I am out of place among all these cooks. Regrettably, I make my soup by opening a can (LOL). Your recipe, however, sounds delicious.

  3. There’s hardly a meal on earth that I love as much as creamy tomato soup with a grilled sharp cheddar sandwich! Sounds like a winning version of the soup here! 😀

  4. It is definitely winter in NYC….and as a diabetic I am always searching for that healthy yet satisfying meal. Thanks so much for the recipe but most especially the how to…I learn best by watching.

    I love soups. They are just so comforting especially during this time of the year. This one looks really easy to make but still so tasty! Will definitely try it out. Thanks!

    I really like that I can make this at home. You made it look so easy. And I would love to try out that KitchenAid blender. It looks really cool.

    1. Thank you Sophie. Yes, it is one of the easier soups to make sure, but without compromise on flavor. As for the immersion blender, it makes things so much easier. The version I bought came with a smoothie cup and food processor too. So it’s multipurpose!
