Ingredients
Main Ingredients List
- 2 pounds ripe tomatoes, quartered
- 1 large onion, chopped
- 4 cloves garlic, whole
- 3 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper

The main ingredients for roasted tomato basil soup are simple and fresh. You need ripe tomatoes for sweetness. I prefer using a mix of colors for a deeper flavor. A large onion adds depth and sweetness when roasted. Whole garlic cloves give a rich taste without being too sharp.
Olive oil is essential for roasting. It helps the vegetables caramelize and adds healthy fats. Use salt and black pepper to enhance the natural flavors. Dried oregano brings an Italian twist while red pepper flakes can add a little heat if you like spice.
Vegetable broth forms the base of the soup. It adds depth without overpowering the fresh flavors. Fresh basil is key for that classic tomato basil taste. I love chopping it just before adding it for a bright flavor burst.
Finally, balsamic vinegar adds a touch of acidity. It balances the sweetness of the tomatoes. For creaminess, choose between heavy cream or coconut milk. Coconut milk adds a nice vegan twist while keeping it rich.
With these ingredients, you can create a soup full of flavor and comfort.

Step-by-Step Instructions
Preheating and Preparing the Oven
First, you need to set your oven to 400°F (200°C). This heat helps the tomatoes caramelize. Next, take a large baking sheet and arrange your quartered tomatoes, chopped onion, and whole garlic cloves. Spread them out in a single layer. This ensures even cooking.
Roasting the Vegetables
Now, drizzle three tablespoons of olive oil over the vegetables. Make sure they all get a good coating. Then, season with one teaspoon of salt, half a teaspoon of black pepper, and one teaspoon of dried oregano. If you like some heat, add a quarter teaspoon of red pepper flakes. Toss everything together gently. Place the baking sheet in the oven and roast for about 30 to 35 minutes. You will know they are done when the tomatoes look caramelized and the onions feel tender.
Blending and Finishing the Soup
Once roasted, take the baking sheet out and let it cool for five minutes. In a large pot, transfer the roasted veggies along with any juices. Add one cup of vegetable broth and bring it to a gentle simmer on medium heat. Stir in one cup of chopped fresh basil leaves and one tablespoon of balsamic vinegar for a kick of flavor. For a smooth soup, use an immersion blender directly in the pot. If you don’t have one, carefully transfer the mixture to a standard blender and blend until creamy and velvety. If you want a richer taste, add a quarter cup of heavy cream or coconut milk, warming it through for another two to three minutes. Be sure to taste and adjust the seasoning as needed.
Tips & Tricks
Enhancing the Flavor
To make your roasted tomato basil soup shine, add more herbs. Try fresh thyme or rosemary for a new taste. You can even add a hint of sugar to balance acidity. Roasting the veggies is key. It brings out the sweet and rich flavors. The caramelization during roasting makes the soup taste deep and hearty.
Adjusting Consistency
If you want a thicker soup, blend in some more tomatoes. For a thinner soup, add extra vegetable broth until you reach your desired texture. An immersion blender works great for a smooth finish. If you prefer a standard blender, do it in small batches. This keeps spills and mess to a minimum.
Serving Suggestions
When serving, top the soup with fresh basil leaves. This adds color and flavor. A drizzle of olive oil makes it extra special. Pair your soup with crusty bread or a grilled cheese sandwich. These sides make for a cozy meal that everyone will love.
Pro Tips
- Choose the Right Tomatoes: Use a mix of different tomato varieties for a more complex flavor. Heirloom tomatoes add sweetness, while Roma tomatoes provide a robust base.
- Don't Skip the Roasting: Roasting enhances the sweetness and depth of flavor in the tomatoes and onions. Ensure they are well-caramelized for the best taste.
- Fresh Basil is Key: Always use fresh basil for the best flavor. Add it at the end of cooking to preserve its vibrant taste and aroma.
- Adjust the Creaminess: For a richer soup, adjust the amount of heavy cream or coconut milk to your preference. Start with a little and add more until you reach your desired consistency.
Variations
Vegan and Dairy-Free Options
You can easily make this soup vegan. Just swap heavy cream for coconut milk. This change keeps the soup creamy and adds a hint of sweetness. I also like to add a splash of lime juice for brightness. It gives a fresh twist that balances the soup's rich flavors.
Alternative Ingredients
If you want to try something new, use other veggies. Roasted red peppers or zucchini work well. Both add a unique taste and texture. You can also play with herbs. Try thyme or parsley instead of basil. Each herb brings its own flavor, making the soup special.
Spicy Version
For those who love heat, add spicy peppers. Jalapeños or serranos can bring the heat up a notch. Another great idea is to mix in some salsa or a dash of hot sauce. This adds a kick and depth to the soup. Just remember, start with a little. You can always add more spice later.
Storage Info
Storing Leftovers
To keep your roasted tomato basil soup fresh, refrigerate it. Use an airtight container. Store it for up to five days. If you want to save it longer, freezing works well. Pour the cooled soup into freezer-safe bags or containers. Leave some space at the top for expansion. This soup can last up to three months in the freezer.
Reheating Techniques
When you want to enjoy your soup again, you can reheat it easily. Use a pot on the stove for gentle heat. Pour in the soup and warm it on low. Stir often to prevent sticking. You can also use the microwave. Place the soup in a microwave-safe bowl. Heat it in short bursts, stirring in between.
To restore texture and flavor, add a splash of broth or water. This keeps the soup from becoming too thick. Taste it before serving and adjust the seasoning if needed. Enjoy your delicious soup just like the first time!
FAQs
Can I use canned tomatoes instead of fresh?
