A Fresh, No-Cook Tomato Soup for Late Summer
If there is one month when tomatoes deserve your full attention, it is September. Early September tomatoes are often at their peak, deeply colored, juicy, fragrant, and packed with the sweet-tart flavor that makes summer produce so special. And because this Antioxidant Gazpacho is served cold, there is no need to turn on the stove and miss out on that fresh-from-the-garden flavor.

Gazpacho is one of my favorite ways to enjoy an abundance of late-summer vegetables. Simply chop, blend, stir, and chill. The result is a vibrant, refreshing soup that tastes like summer in a bowl.
This version takes traditional tomato gazpacho and gives it an extra antioxidant boost with red bell peppers, red onion, garlic, olive oil, lime juice, and BareOrganics Milk Thistle Seed Powder. The combination creates a colorful soup with layers of flavor—and plenty of reasons to make it while tomatoes are still at their best.
The recipe makes eight servings and is gluten-free, grain-free, egg-free, nut-free, soy-free, refined sugar-free, vegetarian, and vegan as written.
Why Early September Tomatoes Are So Good
There is something special about a tomato picked at the end of summer. By early September, tomatoes have had plenty of warm sunshine to develop their flavor, and local tomatoes can be especially juicy and intensely flavored.
For gazpacho, choose ripe plum tomatoes that are deeply colored, fragrant, and firm but not hard. Since tomatoes are the foundation of this soup, their flavor really matters.
Tomatoes also provide lycopene, a carotenoid antioxidant responsible for much of their red color. Lycopene has been widely studied for its antioxidant properties. Interestingly, pairing tomatoes with a source of healthy fat can help the body absorb carotenoids, which makes the olive oil in this gazpacho a particularly flavorful addition.
And unlike a cooked tomato sauce, gazpacho lets you enjoy the fresh, bright character of ripe tomatoes alongside other raw vegetables.
What You’ll Need for Antioxidant Gazpacho
The ingredient list is refreshingly simple:
- Ripe plum tomatoes
- Red bell peppers
- Seedless cucumber
- Red onion
- Serrano chiles
- Garlic
- Rice vinegar
- Fresh lime juice
- Worcestershire sauce
- Tomato juice
- Extra-virgin olive oil
- BareOrganics Milk Thistle Seed Powder
- Sea salt and freshly ground black pepper
The recipe uses four plum tomatoes, two red bell peppers, one cucumber, one large red onion, garlic, and optional serrano chiles as its vegetable base.
The Antioxidant Ingredients in This Gazpacho
One of the best things about this gazpacho is its variety of colorful plant foods. Different fruits and vegetables contain different naturally occurring antioxidant compounds, so eating a colorful assortment is a delicious way to diversify your diet.
Tomatoes: Lycopene Power
Tomatoes are the star of this recipe and one of the best-known food sources of lycopene, a carotenoid with antioxidant activity.
The deep red color of ripe tomatoes is a visual clue that you’re getting plenty of beneficial plant pigments. Tomatoes also contribute vitamin C and other plant compounds to this vibrant soup.
Red Bell Peppers: Vitamin C and Carotenoids
Red bell peppers aren’t just there for color. They’re naturally rich in vitamin C, an important antioxidant nutrient, and contain carotenoids and other plant compounds.
Using red peppers rather than green peppers also gives the gazpacho a sweeter, more rounded flavor that works beautifully with the acidity of the tomatoes, vinegar, and lime.
Red Onion: Quercetin and Other Plant Compounds
That gorgeous red-purple color is another sign that you’re getting a variety of plant pigments. Red onions contain quercetin, a flavonoid with antioxidant properties.
Because the onion is finely chopped rather than cooked, it also contributes a pleasant bite to the finished gazpacho.
Garlic: A Small Ingredient With Big Flavor
Three cloves of garlic give this soup plenty of savory depth. Garlic contains sulfur-containing compounds, including allicin, which is produced when garlic is chopped or crushed.
Here, the garlic is grated directly into the vegetable mixture, making it an easy way to add plenty of flavor without relying on cooking.
Olive Oil: Healthy Fat Meets Antioxidants
The olive oil does more than make the gazpacho silky and satisfying. Extra-virgin olive oil contains polyphenols and other antioxidant compounds, and its healthy fats can also help with absorption of fat-soluble carotenoids such as lycopene.
The recipe blends the olive oil with a little tomato juice and milk thistle powder before stirring it into the soup.
Cucumber: Refreshing and Hydrating
Cucumber brings a cool, crisp quality to gazpacho and helps balance the acidity of the tomatoes and vinegar. It also contributes vitamin C and a variety of plant compounds.
Plus, its high water content makes it especially appealing in a cold soup designed for warm-weather eating.
Serrano Peppers: A Little Heat
Serrano peppers are optional, but I highly recommend them if you enjoy a little heat. They contain capsaicin, the naturally occurring compound responsible for their spicy kick.
Start with one serrano for a gentle level of heat or use two if you want your gazpacho to have more personality. The recipe calls for the peppers to be very finely minced.
Milk Thistle Seed Powder: An Extra Plant-Based Boost
This gazpacho also contains BareOrganics Milk Thistle Seed Powder, which adds another plant-based component to the recipe. Milk thistle contains a group of compounds called silymarin, which have antioxidant activity.
The recipe uses one tablespoon of milk thistle seed powder, blended with tomato juice and olive oil before being incorporated into the gazpacho.
It is important to think of ingredients like milk thistle as part of an overall nutritious eating pattern rather than as a treatment or cure for a health condition.
How to Make Antioxidant Gazpacho
The beauty of this recipe is that there is no cooking required.
First, roughly chop the tomatoes and pulse them in a food processor. The goal is to chop them—not puree them completely. Transfer them to a large bowl, then process the bell peppers, cucumber, onion, and serrano peppers separately.
Grate the garlic directly into the bowl and add the salt, pepper, rice vinegar, lime juice, and Worcestershire sauce. Add most of the tomato juice and stir everything together.
For the final step, blend the remaining tomato juice with the olive oil and milk thistle seed powder until smooth. Stir that mixture into the gazpacho.
Then comes the hardest part: waiting.
The gazpacho needs to chill for at least one hour, although the recipe notes that it gets even better the longer it sits.
As it rests, the flavors have time to mingle and mellow, creating a much more balanced soup.
Tips for Making the Best Tomato Gazpacho
Use the Best Tomatoes You Can Find
Because this recipe is raw, there is nowhere for mediocre tomatoes to hide. Choose ripe, flavorful tomatoes, preferably locally grown when available.
Don’t Over-Process the Vegetables
Gazpacho is meant to have some texture. Pulse the vegetables rather than turning them into a completely smooth puree. The original recipe specifically calls for roughly chopping rather than pureeing the vegetables.
Let It Chill
Give the soup at least an hour in the refrigerator. If you have time, make it several hours ahead. The flavors become more cohesive as the gazpacho rests.
Adjust the Heat
Serrano peppers are optional, so this recipe is easy to customize. For a milder gazpacho, use one serrano and remove the seeds and membranes. For more heat, use two.
Taste Before Serving
Tomatoes vary considerably in sweetness and acidity. Taste the chilled gazpacho before serving and adjust the salt, pepper, or acidity if needed.
How to Serve Antioxidant Gazpacho
This gazpacho makes a beautiful first course, light lunch, or refreshing side dish. For an especially pretty presentation, serve it in chilled bowls or glasses and add a colorful garnish.
The recipe suggests sliced green onion, chopped cucumber, cilantro, finely diced serrano peppers, feta cheese, cooked shrimp, or chopped cilantro.
For a completely plant-based presentation, stick with the vegetables and herbs. For a heartier meal, cooked shrimp makes an especially nice addition.
You can also serve small portions as an elegant appetizer for a late-summer dinner party.
