Introduction
There's something incredibly comforting about a warm bowl of tomato soup, especially when it’s packed with robust flavors from roasted tomatoes. Using a pressure cooker not only speeds up the cooking process but also intensifies the natural sweetness and essence of the tomatoes.
This recipe takes advantage of the pressure cooker’s ability to meld flavors quickly, giving you a delicious soup ready in no time. Perfect for cozy nights or quick lunches, it’s a simple yet satisfying dish that you can easily whip up with minimal prep.
Ingredients
- 2 pounds ripe tomatoes, quartered
Fresh tomatoes are the star of this soup, providing a rich base flavor. Roasting them enhances their natural sugars, giving a depth that canned tomatoes can’t replicate. - 1 medium onion, chopped
Onions add sweetness and aromatic depth to the soup. When sautéed, they caramelize slightly, complementing the roasted tomatoes beautifully. - 3 cloves garlic, minced
Garlic brings a savory punch and aromatic quality to the soup. It enhances the overall flavor profile and adds a warm essence. - 2 cups vegetable broth
Broth serves as the liquid base, imparting additional flavor to the soup. Vegetable broth is light yet flavorful, perfect for these ingredients. - 1 teaspoon dried basil
Basil adds an herbal freshness that pairs beautifully with tomatoes. It also contributes a wonderful aroma that elevates the overall dish. - Salt and pepper to taste
Seasoning is crucial for balancing flavors. Salt enhances the sweetness of the tomatoes while pepper adds a bit of spiciness. - 1 tablespoon olive oil
Olive oil is used for sautéing the onion and garlic, helping to release their flavors. It also adds a fruity richness to the soup. - 1 tablespoon balsamic vinegar
Balsamic vinegar provides a touch of acidity and sweetness, which deepens the flavor of the tomatoes and helps to round out the soup’s taste.
Directions & Preparation
Step 1: Preheat your pressure cooker on the sauté setting.
Starting with a hot pot allows the onion and garlic to sauté properly, which enhances their flavors. Make sure to stir regularly to prevent burning.
Step 2: Add the olive oil, followed by the chopped onion and minced garlic.
Sauté the onion for about 3-4 minutes until it's translucent. Then add the garlic and cook for an additional minute. This step builds the flavor foundation of your soup.
Step 3: Add the quartered tomatoes, dried basil, salt, and pepper to the pot.
Combining the tomatoes with the sautéed onion and garlic ensures their flavors meld. Fresh tomatoes will start to break down when cooked under pressure, yielding a richly flavored base.
Step 4: Pour in the vegetable broth and balsamic vinegar, stirring gently.
This liquid will help create steam for the pressure cooker. Ensure everything is well mixed, as this will enhance the flavor distribution in your soup.
Step 5: Seal the pressure cooker lid and cook on high pressure for 10 minutes.
Cooking under pressure significantly reduces the time needed for the flavors to develop while also ensuring the tomatoes are thoroughly cooked and soft.
Step 6: After the cooking time is up, carefully release the steam according to your pressure cooker instructions.
Allowing the steam to release naturally for a few minutes before a quick release gives the soup time to settle and reduces splattering when opening the lid.
Step 7: Blend the soup until smooth using an immersion blender or regular blender.
Blending creates a luxuriously creamy texture. If using a regular blender, allow the soup to cool slightly before blending to prevent splatters.
Step 8: Taste and adjust seasoning with more salt or pepper if necessary.
Adjusting the seasoning is key to achieving a well-balanced flavor profile. A pinch more salt or drizzle of olive oil can enhance the final dish.
Step 9: Serve hot, garnished with fresh basil leaves or a splash of cream if desired.
Presentation matters, and a garnish of basil or cream can elevate the soup visually as well as in terms of flavor. Enjoy it with crusty bread for a complete meal.

The Importance of Roasting in Flavor Development
Roasting tomatoes before incorporating them into your soup is essential for achieving a rich and complex flavor. The high heat caramelizes their natural sugars, intensifying their sweetness and making for a deeper, more satisfying base. This simple technique transforms the tomatoes, allowing their essence to shine through in every spoonful.
Why Use a Pressure Cooker?
A pressure cooker is a game changer for busy home cooks. It not only speeds up the cooking time significantly but also preserves nutritional value and flavors. By creating a high-pressure environment, the pressure cooker ensures that the ingredients meld together beautifully, producing a final dish that is as flavorful as it is quick to prepare.
Customizing Your Tomato Soup
One of the best parts of making soup is the ability to customize it to your liking. Consider adding a splash of cream for richness or using different herbs like thyme or oregano. You can also throw in vegetables like carrots or bell peppers during the initial sauté. This flexibility makes the recipe not only comforting but also versatile to suit any palate.
