INGREDIENTS FOR ROASTED TOMATO SOUP RECIPE

This roasted tomato soup recipe is best known for its simple ingredients. We are using only fresh ingredients which give it an amazing flavor and texture. This tomato soup is wonderfully creamy, without any cream or dairy, which makes it vegan and dairy-free! Here’s what you need:

  • Fresh Tomatoes: Tomatoes add sweetness and a lightly caramelized flavor to this delicious tomato soup. If you have a garden, fresh tomatoes would be perfect, or you could opt for organic ones to enhance the soup’s flavor.
  • Garlic: Let’s not forget how delicious roasted garlic is and how easy it is to roast alongside tomatoes.
  • Fresh basil: Basil has a slightly sweet flavor and should be added to the recipe before serving, as excessive heat can remove the basil’s flavor and sometimes make it slightly bitter. This herb also helps reduce the acidity of tomatoes.
  • Onion: I used caramelized onion in this tomato soup. The caramelized onion imparts a rich sweetness, depth of flavor, and subtle complexity, elevating the overall taste profile by balancing the acidity of the tomatoes and adding a savory, umami undertone.
  • Tomato paste (optional): This addition imparts a slightly more robust tomato taste to the soup.
  • Sugar: This is an optional ingredient. Use a tablespoon if your tomatoes are not ripe or sweet enough.
  • Optional Ingredients: I have included some optional ingredients that you can add to the soup to make it your own. This is your chance to get a little creative.

HOW TO MAKE ROASTED TOMATO SOUP

Now that we have our ingredients, let’s embark on the culinary journey of crafting this delightful roasted tomato soup.

Step 1: Roasting the Tomatoes and Garlic

Preheat your oven to 400°F (200°C). Place the halved tomatoes and peeled garlic cloves on a baking sheet. Drizzle with olive oil, ensuring each tomato is coated. Sprinkle with salt and black pepper. Roast in the oven for 40-45 minutes or until the tomatoes are caramelized and fragrant.

Step 2: Caramelizing the Onions

While the tomatoes are roasting, heat olive oil in a large pot over medium heat. Add thinly sliced onions and cook until golden brown and caramelized. This process adds a sweet depth to the soup, complementing the acidity of the tomatoes.

Step 3: Creating the Flavor Base

Once you have roasted the tomatoes and garlic, let them cool down for about 10 minutes. After that, transfer them to a food processor or blender and blend until they become smooth. Following this, add the caramelized onions and basil and blend once again. Alternatively, you can use an immersion blender to puree the soup directly in the pot.

Step 4: Infusing Flavors

Transfer the mixture into the pan and add water or vegetarian broth according to desired consistency, using less for a thicker soup and more for a lighter version.

Stir in dried oregano and tomato paste (if using) to enhance herbal and savory notes. Adjust sweetness with brown sugar and season with salt and black pepper to taste.

Step 5: Optional Enhancements

Here’s where you can tailor the soup to your preferences. For a creamy vegan version, swirl in light or whole coconut milk. If you crave indulgence, opt for whole milk, cream, or even a sprinkle of Parmesan cheese for that extra umami kick. For a richer flavor, stir in a couple of tablespoons of butter.

Step 6: Simmering to Perfection

Allow the soup to simmer over low heat for 15-20 minutes, letting all the flavors meld together. The kitchen will be filled with an irresistible aroma, building anticipation for the deliciousness that awaits.

HOW TO CUSTOMIZE THIS TOMATO SOUP RECIPE

While the basic roasted tomato soup recipe is a flavorful delight on its own, the beauty of cooking lies in the ability to customize recipes to suit personal preferences. Here are some creative ways to tailor the roasted tomato soup to your liking:

  1. Spice it Up:
    • For a kick of heat, add red pepper flakes or a dash of cayenne pepper. Experiment with different chili varieties to find the level of spiciness that tickles your taste buds. A pinch of smoked paprika can also add a subtle smokiness to the roasted tomato soup.
  2. Herb Infusions:
    • Get creative with herbs to elevate the soup’s aroma and flavor. Thyme, rosemary, or even a hint of sage can bring unique herbal undertones. Consider adding a handful of fresh parsley or cilantro for a burst of freshness.
  3. Roasted Red Pepper Twist:
    • Introduce roasted red peppers to the mix for a slightly sweet and smoky flavor. Simply roast red peppers alongside the tomatoes and garlic, then blend them with the other ingredients. This variation adds depth and complexity to the roasted tomato soup.
  4. Citrus Zest:
    • Brighten up the roasted tomato soup by incorporating citrus zest. A touch of grated lemon or orange zest just before serving can add a zesty, aromatic dimension. This small addition can cut through the richness and bring a refreshing contrast.
  5. Protein Boost:
    • Turn your tomato soup into a heartier meal by adding protein. Shredded cooked chicken, diced tofu, or cooked lentils can make the soup more substantial. It’s a great way to transform it into a complete and satisfying dish.
  6. Grain or Pasta Additions:
    • For a more substantial texture, consider adding cooked grains like quinoa or rice directly to the roasted tomato soup. Alternatively, throw in some small pasta shapes during the last few minutes of simmering for a comforting, one-pot meal.
  7. Smoked Ingredients:
    • Infuse a smoky essence by adding ingredients like smoked tomatoes, smoked paprika, or a touch of liquid smoke. This can create a delightful complexity reminiscent of outdoor cooking.
  8. Mediterranean Flair:
    • Give your soup a Mediterranean twist by incorporating olives, capers, or a splash of balsamic vinegar. These ingredients add a tangy, briny element that pairs wonderfully with the sweetness of the roasted tomatoes.
  9. Garnish Galore:
    • Elevate the visual appeal and flavor by experimenting with various garnishes. Try croutons for crunch, a dollop of Greek yogurt or sour cream for creaminess, or a sprinkle of grated Parmesan cheese for added richness.
  10. Roasted Garlic Infusion:
    • If you’re a garlic enthusiast, roast additional garlic cloves and blend them into the roasted tomato soup for an intensified garlic flavor. This creates a robust and aromatic profile that garlic lovers will appreciate.
  11. Customizing Texture:
    • Control the texture of your soup by adjusting the blending time. For a chunkier version, pulse the immersion blender a few times, leaving some tomato pieces intact. If you prefer silkiness, blend until completely smooth.
  12. Garnish with Freshness:
    • Finish off your masterpiece with a drizzle of high-quality olive oil, a handful of freshly chopped basil or cilantro, or a swirl of balsamic reduction for a burst of freshness and visual appeal.

Remember, cooking is an art, and these suggestions are just starting points. Feel free to mix and match these customization ideas to create a roasted tomato soup that perfectly suits your palate.

STORAGE OF TOMATO SOUP RECIPE

Proper storage is crucial to maintaining the freshness and flavor of your delicious roasted tomato soup. Follow these guidelines to ensure your soup stays safe and tasty:

  1. Refrigeration:
    • Allow the roasted tomato soup cool to room temperature before refrigerating.
    • Transfer the soup to an airtight container or cover the pot with plastic wrap.
    • Refrigerate within 2 hours of cooking.
    • Store in the refrigerator for up to 3-4 days.
  2. Freezing:
    • If you’ve made a large batch or want to store the roasted tomato soup for an extended period, freezing is a great option.
    • Cool the soup completely before transferring it to freezer-safe containers or resealable plastic bags.
    • Leave some space at the top of the container to allow for expansion.
    • Label containers with the date for easy tracking.
    • Freeze for up to 3-4 months.
  3. Thawing:
    • When ready to use frozen roasted tomato soup, transfer it to the refrigerator the night before to allow for slow and safe thawing.
    • Alternatively, use the defrost function on your microwave or thaw in a pot on the stove over low heat.
    • Once thawed, reheat thoroughly before serving.
  4. Reheating:
    • Reheat refrigerated or thawed soup on the stove over medium heat, stirring occasionally.
    • Ensure the soup reaches a minimum internal temperature of 165°F (74°C) for food safety.
    • If the soup has thickened during storage, you can add a little water or broth to reach your desired consistency.
  5. Avoid Dairy Separation:
    • If your roasted tomato soup contains dairy ingredients (like cream or milk), you may notice separation after refrigeration. Gently stir or whisk the soup as you reheat it to recombine the ingredients.
  6. Flavor Adjustment:
    • It’s normal for flavors to develop and intensify as the roasted tomato soup sits. Taste the soup after reheating and adjust seasonings if needed.
  7. Portioning for Convenience:
    • Consider storing the soup in smaller, individual portions to make reheating and serving more convenient.
  8. Containers:
    • Opt for airtight containers or vacuum-sealed bags to prevent freezer burn and maintain freshness.
  9. Avoid Repeated Freezing and Thawing:
    • To preserve the quality of the soup, try to avoid multiple cycles of freezing and thawing. If you thaw a portion, try to use it within a reasonable time.
  10. Check for Signs of Spoilage:
    • Always check the soup for any signs of spoilage before consuming, such as off smells, unusual colors, or changes in texture.

By following these storage guidelines, you can enjoy your roasted tomato soup at its best, whether freshly made or from the freezer, whenever a comforting bowl is calling your name.
