Ingredients
- 2 lbs ripe tomatoes, halved
Ripe tomatoes are the star of this dish, providing natural sweetness and acidity. Roasting enhances their flavor, concentrating the sugars and leading to a deeper, more vibrant soup. - 1 onion, chopped
Onions add a robust base flavor to the soup. When sautéed with the tomatoes, they caramelize slightly, contributing sweetness that balances the acidity of the tomatoes. - 4 cloves garlic, minced
Garlic brings a fragrant, savory punch to the mix. Its bold flavor enhances the overall taste of the soup and complements the sweetness of the tomatoes. - 2 cups vegetable broth
Vegetable broth serves as the liquid base for the soup, adding layers of flavor. You can adjust the amount based on your preferred soup consistency, making it key for overall texture. - 2 tablespoons olive oil
Olive oil aids in roasting the vegetables to perfection, helping to develop the rich flavors through caramelization while also contributing a bit of healthy fat. - Salt and black pepper to taste
Seasoning is crucial; it elevates the dish by enhancing the natural flavors of the ingredients. Adjusting the salt and pepper allows you to achieve the perfect balance. - 1 teaspoon dried basil
Dried basil adds an herbal note that pairs beautifully with tomatoes, evoking classic Italian flavors. It infuses the soup with a warm, aromatic quality. - 1 tablespoon balsamic vinegar (optional)
Balsamic vinegar provides a hint of acidity and sweetness that can brighten the finished soup. It’s optional but adds a nice depth to the overall flavor profile.
Directions & Preparation
Step 1: Preheat your pressure cooker in sauté mode.
Starting with the sauté mode allows the garlic and onions to caramelize, which layers the soup with complex flavors. This initial step is crucial as it sets the foundation for the soup, enhancing every subsequent ingredient added.
Step 2: Add the olive oil, chopped onion, and minced garlic. Sauté until soft and translucent.
Cooking the onion and garlic until they're soft allows their natural sugars to develop, creating a sweeter base. This aromatically rich start is essential for deepening the overall taste of the soup.
Step 3: Place the halved tomatoes in the pot, cut side up. Sprinkle with salt, pepper, and dried basil.
By roasting the tomatoes directly inside the pressure cooker after the aromatics, you'll ensure that their flavors meld perfectly. The cut sides open up, allowing the seasonings to penetrate the tomatoes, intensifying their natural sweetness.
Step 4: Pour in the vegetable broth and add balsamic vinegar if using. Close the lid and set the pressure to high for 10 minutes.
Adding broth creates the soup’s body. The high pressure cooks everything quickly, ensuring that the tomatoes break down and release their juices while becoming incredibly tender, which is vital for a silky soup consistency.
Step 5: Once cooking time is up, use a quick release to vent the pressure. Carefully open the lid when safe to do so.
Quick releasing the pressure halts cooking immediately, preventing overcooking. This method helps retain the bright flavors and vivid color of the tomatoes, making the final soup appealing and fresh.
Step 6: Use an immersion blender to purée the soup until smooth, or transfer to a blender in batches if necessary.
Blending the soup creates the right texture; it should be velvety. If using a traditional blender, allow it to cool slightly before blending to avoid splatters. This step is crucial for achieving a refined soup consistency.
Step 7: Taste and adjust seasoning before serving, adding more salt, pepper, or basil if needed.
Since flavors can vary widely between ingredients, adjusting seasoning at this final stage ensures the soup meets your preference. Tasting and fine-tuning flavor at the end is essential for a balanced dish.

Roasted Tomato Technique
Roasting tomatoes intensifies their natural sweetness and flavor. The process caramelizes their sugars, which creates a richer base for the soup. You can use different types of tomatoes, such as heirloom or grape, for varied flavor profiles; however, using ripe seasonal tomatoes will yield the best results.
Perfect Pairings
This roasted tomato soup pairs wonderfully with a variety of sides, enhancing your meal experience. A crispy slice of grilled cheese or a hearty breadstick can complement the smoothness of the soup perfectly. Additionally, topped with fresh basil or a dollop of crème fraîche can elevate the dish visually and in flavor.
Customizing Your Soup
This recipe serves as a fantastic base that lends itself to customization. You can add ingredients like red pepper flakes for heat or toss in some spinach or shredded carrots for extra nutrition. Adjusting the spices and herbs can change the aroma and taste, making it a versatile option for your recipe repertoire.
FAQs
What if the soup is too thick?
If the soup turns out thicker than desired, simply add more vegetable broth to achieve your preferred consistency. Blend again if necessary.
