What is Homemade Roasted Tomato Basil Soup?
Homemade roasted tomato basil soup is a delightful blend of oven-roasted tomatoes, fresh basil, and aromatic garlic, all simmered to create a smooth, comforting dish.
By roasting the tomatoes, you amplify their natural sweetness and depth of flavor. Combined with the fragrance of fresh basil, garlic, and a splash of olive oil, each spoonful is like a warm hug in a bowl.
It’s simple yet sophisticated, making it a perfect dish for both weeknight dinners and leisurely weekend gatherings. The texture can be adjusted based on your preference—smooth and creamy or chunky with bits of caramelized tomato.
What Does It Taste Like?

Why This Recipe Works
This recipe isn’t just about throwing ingredients into a pot. Here are the reasons that truly set it apart:
1. Flavor Development through Roasting
Roasting tomatoes intensifies their flavor. High heat caramelizes the natural sugars in the tomatoes, releasing flavors you wouldn’t achieve by just boiling them. Additionally, roasting garlic mellows its sharpness, creating a buttery richness.
2. Fresh Herb Aroma
Basil brings a refreshing dimension. Its vibrant notes are a perfect match for the soup’s acidity, cutting through the richness and balancing the dish beautifully. Using fresh basil instead of dried makes a significant difference.
3. Quick Preparation
Despite the layered flavors, this soup is incredibly straightforward to make. With a little chopping and some patience while roasting, you can create something that tastes as though it simmered for hours.
4. Health Benefits
With tomatoes as the star ingredient, you gain all sorts of nutritional bonuses. Tomatoes are packed with vitamins C and K, as well as antioxidants that can help promote heart health. Add in basil and garlic, and you’re embracing a dish that’s not just delicious but health-conscious too.
Ingredients For Homemade Roasted Tomato Basil Soup
Before we begin, ensure your kitchen is stocked with the following ingredients:
- 6 whole garlic cloves, unpeeled
- 1/2 cup finely chopped yellow onion
- 3 pounds fresh tomatoes, any type, halved
- 4 tablespoons extra virgin olive oil, divided
- 1 tablespoon coarse kosher salt
- Salt and freshly ground black pepper, to taste
- 1 1/2 teaspoons freshly cracked black pepper
- 5 cups low-sodium vegetable stock or chicken stock
- 1/4 teaspoon crushed red pepper flakes
- 1/2 cup chopped fresh basil leaves

Step by Step Instructions
Let’s roll up our sleeves and dive into this delicious creation.
Step 1: Prepare the Tomatoes and Garlic
Start by preheating your oven to 400°F (200°C). This heat is crucial for roasting. Next, take your tomatoes, halve them, and place them cut-side-up on a baking sheet. Don’t forget to add your unpeeled garlic cloves to the tray, too.
The more the merrier! Drizzle with 2 tablespoons of olive oil and sprinkle with salt and black pepper. Roasting these ingredients will unlock their full potential.
Step 2: Roast in the Oven
Slide the baking sheet into the oven and roast for about 30-40 minutes. You’re looking for slightly caramelized edges on the tomatoes and a toasty aroma filling your kitchen. Your patience will pay off here.
Step 3: Sauté Onion and Garlic
While the tomatoes are roasting, heat the remaining 2 tablespoons of olive oil in a large pot over medium heat. Add the finely chopped onion. Sauté until translucent, about 5 minutes. This step builds a flavor base for your soup.
When you think the onions are just right, add the roasted garlic (you’ll want to squeeze the cloves out of their skins) and cheerfully stir for another minute or two.
Step 4: Combine Roasted Ingredients
When the tomatoes come out, toss them into the pot with the sautéed onions. Pour in the vegetable stock (or chicken stock if you prefer) and stir in crushed red pepper flakes. Give everything a mix, and bring it to a gentle boil.
Step 5: Blend It Up!
Once boiling, lower the heat and allow it to simmer for approximately 10 minutes. This extra time allows flavors to mingle.
After that, it’s blending time! Use an immersion blender (or carefully transfer to a regular blender) to purée the soup until smooth. Remember, blending hot liquids can be tricky—take it slow.
Step 6: Add Fresh Basil
After blending, stir in the roughly chopped fresh basil. Allow it to infuse its flavor for a few minutes. This vibrant herb adds a fresh finish and raises the taste to a new level.
Notes
Here are some valuable tips to ensure your soup turns out perfectly:
- Use Fresh Ingredients: Fresh tomatoes and herbs will drastically improve the flavor.
- Don’t Skip the Roasting: Roasting is key to achieving the depth of flavor this soup is known for.
- Adjust Seasonings: Everyone’s palate is different. Taste as you go and adjust salt and pepper as needed.
- Make it Creamy: For a richer soup, add a splash of heavy cream or a dollop of crème fraîche before serving.
- Batch Cooking: This soup freezes wonderfully. Make a large batch and freeze portions for quick future meals.

How To Store The Leftovers?
Let the soup cool completely before transferring it to airtight containers. It keeps well in the fridge for up to 5 days or you can freeze it for up to three months. If you’re freezing, be sure to leave some room in the containers for expansion.

Sides For Homemade Roasted Tomato Basil Soup
Enhance your meal experience with these complementary sides:
1. Grilled Cheese Sandwich
A classic pairing, a gooey grilled cheese makes each spoonful of soup more exciting. Choose sharp cheddar or a melty Gruyère for unforgettable bites.
2. Caprese Salad
Slicing fresh tomatoes, mozzarella, and basil, drizzling with balsamic reduction creates a light, refreshing counterpoint to the warmth of the soup.
3. Garlic Bread
Crusty yet tender, garlic bread pairs beautifully. Spread a flavorful garlic butter on your favorite loaf, toast it up, and serve on the side.
4. Simple Garden Salad
Throw together some mixed greens, cherry tomatoes, and cucumbers dressed in olive oil and lemon juice. The crunchiness adds a delightful contrast to the soup’s silky texture.
What Are Some Alternative Choices to the Ingredients?
Sometimes, flexibility is key in the kitchen. Here are some alternatives to consider:
1. Fresh Tomatoes
If fresh tomatoes aren’t available, canned tomatoes can step in just fine. Opt for whole peeled or diced tomatoes—just remember to reduce the overall cooking time since they’re pre-cooked.
2. Vegetable Stock
Chicken stock is a great substitute for those not vegetarian. For a gluten-free option, check that your stock is appropriately labeled.
3. Olive Oil
If you’re out of olive oil, feel free to use vegetable or canola oil. Each will impart its own unique flavor profile.
4. Fresh Basil
No fresh basil? No worries! Dried basil can work in a pinch, just remember to use less (about 1 teaspoon) as dried herbs have more concentrated flavors.
