Ingredients
List of Needed Ingredients
To make this roasted tomato basil soup, gather these ingredients:
- 2 pounds ripe tomatoes, halved
- 1 medium onion, chopped
- 4 cloves garlic, unpeeled
- 1/4 cup extra virgin olive oil
- Sea salt and freshly ground black pepper, to taste
- 1 tablespoon balsamic vinegar
- 1 cup fresh basil leaves, roughly chopped
- 2 cups vegetable broth (homemade or store-bought)
- 1/2 cup heavy cream (or coconut cream for a dairy-free option)
Fresh Ingredients vs. Store-bought
Fresh ingredients make a big difference in flavor. Using ripe tomatoes gives the soup a sweet taste. Fresh basil adds a bright, herby note. Store-bought ingredients can be convenient, but they may lack the same depth. For the best soup, choose fresh tomatoes and basil when possible. If you can't find ripe tomatoes, look for high-quality canned ones as a backup.
Substitute Options for Key Ingredients
If you need to make some swaps, don't worry. Here are some options:
- Tomatoes: Use canned tomatoes if fresh ones aren't available.
- Onion: Shallots or leeks work well if you don't have onions.
- Heavy cream: Coconut cream gives a nice, creamy texture without dairy.
- Vegetable broth: Chicken broth can replace vegetable broth for more flavor.
These substitutes will keep your soup tasty and comforting!

Step-by-Step Instructions
Prepping the Vegetables
Start by preheating your oven to 400°F (200°C). This is the best temperature for roasting. Next, take 2 pounds of ripe tomatoes and cut them in half. Then, chop one medium onion into small pieces. Don’t forget the garlic! You need 4 cloves, and leave them unpeeled for now.
Spread the halved tomatoes, chopped onion, and unpeeled garlic on a large rimmed baking sheet. Drizzle 1/4 cup of extra virgin olive oil over the veggies. Then, sprinkle sea salt and freshly ground black pepper on top. Toss everything lightly to coat well. This step makes all the flavors come together.
Roasting Process Details
Now, place the baking sheet in the oven. Roast the vegetables for 30-35 minutes. You will know they are ready when the tomatoes become caramelized and the onions soften. This step adds a lovely sweetness to your soup.
Once roasted, take the tray out and let it cool for a few minutes. It’s time to peel the garlic cloves. They should be soft, and the skins will slip off easily. This is a fun part!
Blending and Finishing the Soup
In a large pot, combine the roasted tomatoes, onions, peeled garlic, and 1 tablespoon of balsamic vinegar. Add 2 cups of vegetable broth and 1 cup of roughly chopped fresh basil leaves. Stir gently to mix everything. Bring the mixture to a simmer over medium heat.
For the fun part, use an immersion blender to puree the soup until it's smooth. If you don’t have one, you can use a regular blender. Just remember to let the soup cool slightly first to avoid mess.
After blending, return the soup to the pot. Stir in 1/2 cup of heavy cream (or coconut cream for a dairy-free option). Heat the soup through and taste. Adjust the seasoning with more sea salt and black pepper as needed.
Serve the soup hot. Garnish with extra basil leaves and a drizzle of olive oil. Enjoy your delicious roasted tomato basil soup!
Tips & Tricks
Enhancing Flavor Profiles
To boost the flavor, think about adding fresh herbs. Fresh thyme or oregano can elevate the taste. You might also try a pinch of red pepper flakes for a bit of heat. A splash of lemon juice brightens the soup, adding freshness. If you want depth, consider using smoked salt instead of regular sea salt.
Common Mistakes to Avoid
One mistake is not roasting the tomatoes long enough. Roast them until they are caramelized for rich flavor. Another mistake is using too much cream. Start with a small amount and adjust to taste. Also, avoid skipping the balsamic vinegar; it adds a nice tang. Always taste your soup before serving; it helps you adjust the seasoning.
Making Ahead and Reheating
You can make this soup a day ahead. Let it cool, then store it in the fridge. When reheating, do it slowly over low heat. If the soup thickens too much, add a splash of broth. You can also freeze the soup for later. Just remember to let it cool completely before freezing.
Pro Tips
- Choose the Right Tomatoes: For the best flavor, select ripe, in-season tomatoes. Heirloom varieties add a unique sweetness and complexity to your soup.
- Don't Skip the Roasting: Roasting the tomatoes and onions enhances their natural sweetness and adds depth to the overall flavor of the soup.
- Use Fresh Basil: Fresh basil elevates the dish with its aromatic qualities. Add it at the end of cooking to maintain its vibrant flavor.
- Adjusting Consistency: If you prefer a thicker soup, reduce the amount of vegetable broth. For a thinner consistency, add more broth or cream until desired.
Variations
Vegan Adaptations
You can easily make this soup vegan. Simply swap the heavy cream for coconut cream. This keeps the soup creamy without any dairy. You might also want to check your vegetable broth. Make sure it is vegan-friendly. This small change allows everyone to enjoy the soup.
Adding Protein Options
If you want to add protein, consider chickpeas or lentils. Both add great texture and nutrition. You can also use white beans for a creamier feel. Just add them when you blend the soup. This makes it heartier and more filling.
Flavor Variations (Spices & Herbs)
To change the flavor, try different spices and herbs. You can add some red pepper flakes for heat. A pinch of cumin can add depth too. Fresh thyme or oregano works well with the tomatoes. You can mix and match to find your favorite flavor.
Storage Info
Refrigeration Guidelines
After you make the soup, let it cool first. Pour it into a clean, airtight container. Store it in the fridge. It will stay fresh for 3 to 5 days. Always check for signs of spoilage before eating. If you see mold or an odd smell, throw it away.
Freezing Instructions
You can also freeze the soup for later. Cool it completely before freezing. Use freezer-safe bags or containers. Leave some space at the top for expansion. The soup keeps well for 3 months. When you’re ready to eat it, move it to the fridge to thaw overnight.
Best Ways to Reheat
To reheat the soup, use a pot on the stove. Heat it over medium until warm. Stir often to avoid burning. You can also use the microwave. Pour the soup into a microwave-safe bowl, cover it, and heat in intervals. Stir in between to heat evenly. Add a splash of water or broth if it’s too thick. Enjoy it warm with fresh basil on top!
