I literally stumbled on this magical recipe. I had a red onion in the freezer and tomatoes that I didn’t want to spoil before going on a road trip to meet the newest baby in the family! Jarred the tomato soup before leaving town and just put it in the fridge jarred so we’d have something when we got back home. My husband was the first to have it when we got home. I knew it was that good when he said I hope you wrote down how you did this. It is that good!

How About Recipe Variations For Tomato Soup & Topping Ideas?

For this tomato soup recipe, the only “tricky” ingredient may be the sumac. Check out this Master Class article for some comparable replacements and to learn more about sumac’s flavor.

I sometimes add one or two handfuls of fresh sweet basil and turn this into a homemade tomato basil soup recipe.

If not vegan, then the topping variations for this tomato soup recipe are pretty standard with some sour cream and shredded cheese. Don’t forget that grilled cheese sandwich!

If vegan, I have topped this with vegan sour cream and vegan shredded sharp cheddar, or a good quality balsamic vinegar.

Add flavorless protein powder for even more protein. Here is the all-plant protein powder I use. I love it because it is truly tasteless and adds 10 grams of protein to this meal when adding one serving. It’s one of my go-to ways to add more protein to soups, pancakes, and smoothies.

Notes + Tips To Make This Homemade Tomato Soup Recipe Even Easier

  • If using whole tomatoes, quarter them. If using Campari tomatoes, half them. Baby tomatoes can be cooked whole.
  • If using a food processor or blender to puree the tomato soup, allow it to cool for about 15 minutes off the burner it was cooking on and with the lid off the pot so you don’t ruin your blender. For this reason, a hand puree tool is helpful.
  • Before jarring the soup, make sure the tomato soup is cooled!
  • Use a red onion
  • For this recipe, I used this minced garlic instead of using fresh. Fresh works just as well.
  • Don’t leave out the sumac. It’s not in every grocery store. I linked the one I use. I get it from World Market.
  • Any tomatoes will work but if you want to stay true to this recipe, I used 1 pound of Campari tomatoes and 1 pound of baby tomatoes. Why? Because I wanted to use all my leftover tomatoes before going out of town.
