Ingredients For Roasted Tomato Basil Soup
Roma tomatoes: These are plum tomatoes known for their firm flesh and low moisture, perfect for roasting.
Onion: Adds a sweet and savory depth to the soup when sautéed.
Garlic: Provides a pungent, aromatic flavor that enhances the overall taste.
Chicken or vegetable broth: Serves as the base liquid, adding richness and depth.
Fresh basil leaves: Imparts a fresh, herbal aroma and flavor to the soup.
Olive oil: Used for roasting and sautéing, it adds a subtle fruitiness and richness.

Technique Tip for This Soup
When roasting tomatoes, ensure they are cut side up on the baking sheet. This allows the natural sugars in the tomatoes to caramelize, enhancing their sweetness and depth of flavor. Additionally, using a high-quality olive oil can significantly impact the taste, so opt for extra virgin if possible. When blending the soup, if you prefer a creamier texture, consider adding a splash of cream or a dollop of yogurt before serving.

How to Store or Freeze This Soup
Allow the roasted tomato basil soup to cool to room temperature before storing. This prevents condensation from forming inside the storage container, which can dilute the soup and affect its flavor.
Transfer the soup to an airtight container. Glass containers are ideal as they do not retain odors and are easy to clean. Make sure to leave about an inch of space at the top to allow for expansion if you plan to freeze it.
For short-term storage, place the container in the refrigerator. The soup will stay fresh for up to 4 days. When reheating, do so gently over medium heat to preserve the flavors of the basil and roasted tomatoes.
For long-term storage, consider freezing the soup. Divide it into individual portions using freezer-safe bags or containers. This makes it easy to thaw only what you need, reducing waste.
When using freezer bags, lay them flat in the freezer until solid. This method saves space and speeds up the thawing process.
Label each container or bag with the date and contents. This helps you keep track of how long the soup has been stored and ensures you use the oldest batches first.
To thaw, transfer the frozen soup to the refrigerator and let it defrost overnight. If you're in a hurry, you can also use the defrost setting on your microwave or place the sealed bag in a bowl of cold water.
Once thawed, reheat the soup on the stovetop over medium heat, stirring occasionally. Taste and adjust the seasoning with salt and pepper as needed, as freezing can sometimes dull flavors.
Garnish with fresh basil leaves or a drizzle of olive oil before serving to enhance the fresh, vibrant flavors of the soup.
How to Reheat Leftovers
On the stovetop: Pour the soup into a saucepan and heat over medium-low heat. Stir occasionally to ensure even heating. Once it starts to steam and small bubbles form around the edges, it's ready to serve.
In the microwave: Transfer the soup to a microwave-safe bowl. Cover with a microwave-safe lid or a paper towel to prevent splatters. Heat on high for 1-2 minutes, stirring halfway through. Continue heating in 30-second intervals until the soup is hot throughout.
In the oven: Preheat your oven to 350°F (175°C). Pour the soup into an oven-safe dish and cover with foil. Heat for about 20-25 minutes, stirring halfway through, until the soup is warmed to your liking.
Using a slow cooker: Pour the soup into the slow cooker and set it to low. Allow it to heat for 1-2 hours, stirring occasionally, until the soup reaches the desired temperature.
With a double boiler: Fill the bottom pot with water and bring it to a simmer. Place the soup in the top pot and stir occasionally. This gentle method prevents scorching and maintains the soup's creamy texture.
