Nothing soothes the soul more than a bowl of classic tomato soup. And it’s even better when you make it yourself, such as in this plant-based, vegan recipe. It’s so easy! With only 5 ingredients (other than pantry staples), you can whip up this old-fashioned tomato soup recipe in no time.

Best of all, the ingredients for this recipe are easy to keep on hand, such as onions, canned tomatoes, vegetable broth, and dried herbs, making it a go-to recipe to whip up any night of the week. You can let it gently simmer while you’re getting the rest of your meal together. And when it’s all done, pack away leftovers to heat up at work the next day, or to pack in your kids’ lunch boxes. I love this recipe served with a simple sandwich, such as this Greek Chickpea Sandwich recipe, or a hearty salad, such as this Mandarin Quinoa Kale Bowl.

This tomato soup is rich in the hearty flavors of tomatoes, which are packed with fiber, vitamin C, and lycopene—an antioxidant compound with cancer-fighting properties, as well as heart-health activity. It’s a good idea to try to fit healthy tomatoes into your diet at least a few times per week. So, get that soup pot out and cook up this recipe.

Here’s an interesting fact: This Classic Tomato Soup recipe is one of my most popular recipes ever on Pinterest. It just goes to show you that often the simple things are the best.
