For the tastiest zucchini tomato soup, I sauté zucchini and onion and simmer them with canned tomatoes, tomato paste, and a few more ingredients until the flavor turns rich and deep. Finished with quick blend and heavy cream and Parmesan cheese. It's ready in about an hour, with a bright, tomato depth that combines freshness and comfort.
Dice onion and zucchini into small cubes and set aside.
Preheat a pot over medium heat. Add canola oil to the pot.
Add diced onions to the pot and saute until transparent.
Add diced zucchini, mix and saute for a couple of minutes.
Add the entire content of the canned diced tomatoes.
Stir in tomato paste.
Add sugar, salt, and red pepper flakes and stir well.
Simmer for a few minutes and then add warmed chicken stock.
Lower heat to medium-low. Stir, cover, and cook for about 30 minutes. Stir once in a while.
Add fresh basil and cook for a couple more minutes.
Take soup off heat and use an immersion blender to blend it until there is no more chunks. (Or you can leave a few little chunks if that's your preference.)
Place the pot back on the stove, still on medium-low, and stir in heavy cream and freshly grated Parmesan cheese. Taste to see if you need to add more salt.
Cook for just a couple more minutes. Take off heat and serve.

Notes
Need to add move vegetables? Hiding vegetables in soup is a great way to get your family to eat more veggies – I do it all the time! These are some easy-to-hide vegetables that you can add: carrots, peas, summer squash, and even a few broccoli or cauliflower. Don’t add too much broccoli or cauliflower because they have a stronger flavor and are easier to detect.
Storage – Transfer leftover soup into a jar or other airtight food storage container. Store it in the refrigerator for 3 to 4 days.
Reheating – For the best consistency, reheat this tomato soup in a sauce pot, on the stove, over medium-low heat. Make sure to stir occasionally. You can also microwave it in increments of about 45 seconds and stirring in between until warmed through.
Freezing - check the post for freezing instructions.
