What Ingredients You Will Need

This comforting creamy roasted tomato basil soup recipe uses straightforward, wholesome ingredients that come together beautifully without any fuss. Most are pantry staples or easy to find at your local market, making this a go-to recipe year-round.

Fresh Tomatoes: About 3 pounds (1.4 kg) of ripe Roma or vine-ripened tomatoes, halved or quartered (they roast beautifully and provide rich flavor).
Fresh Basil Leaves: 1 cup (loosely packed), chopped (for that signature fresh herbal note).
Garlic Cloves: 4-5, peeled and smashed (adds depth and a subtle kick).
Olive Oil: 3 tablespoons (I prefer a good-quality extra virgin olive oil like Colavita for richness).
Yellow Onion: 1 medium, diced (adds sweetness and body to the soup).
Vegetable or Chicken Broth: 3 cups (720 ml) (homemade or store-bought, choose low sodium for better control).
Heavy Cream or Coconut Cream: 1/2 cup (120 ml) (use coconut cream for a dairy-free twist).
Salt and Freshly Ground Black Pepper: To taste (season carefully to enhance the natural flavors).
Optional: A pinch of red pepper flakes for a subtle heat, or a teaspoon of sugar if your tomatoes are a bit too acidic.

For the best texture, I recommend using firm, ripe tomatoes that hold up well during roasting without turning mushy. If you can find local farmers’ market tomatoes, even better—they tend to have more flavor and fewer preservatives. And if fresh basil isn’t in season, frozen basil can work in a pinch, although the fresh stuff makes a noticeable difference in aroma.

Not into cream? Greek yogurt or cashew cream can be swapped in to keep things creamy but lighter. Just remember to add those at the end and gently warm the soup to avoid curdling.

Equipment Needed

Baking Sheet: For roasting the tomatoes and garlic—any rimmed sheet works well to catch juices.
Large Pot or Dutch Oven: To cook the onions and simmer the soup.
Immersion Blender or Stand Blender: To puree the soup until silky smooth (I love the immersion blender for easy cleanup).
Sharp Knife and Cutting Board: For chopping the vegetables and basil.
Measuring Cups and Spoons: For precise ingredient amounts.
Ladle and Soup Bowls: To serve your delicious creation.

If you don’t have a fancy blender, no worries! A sturdy food processor can do the job, just blend in batches and be careful with hot liquids. For roasting, I’ve even used a cast-iron skillet when I didn’t have a baking sheet handy—it works just fine, though cleaning can be a bit more involved.

Keeping your knives sharp makes a world of difference here, especially when prepping tomatoes. I like to sharpen mine regularly to make chopping effortless and safe.

Preparation Method

Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or foil for easy cleanup.
Prepare the tomatoes and garlic: Wash and halve (or quarter) the tomatoes depending on size. Spread them evenly on the baking sheet. Toss the garlic cloves in olive oil and nestle them among the tomatoes.
Drizzle 2 tablespoons of olive oil over the tomatoes and garlic. Sprinkle with a pinch of salt and freshly ground black pepper. Roast in the oven for 25-30 minutes, or until the tomatoes are soft and slightly caramelized around the edges.
While the tomatoes roast, sauté the onions: Heat 1 tablespoon olive oil in a large pot over medium heat. Add the diced onions and cook for about 8-10 minutes, stirring occasionally, until they turn translucent and start to caramelize slightly.
Once the tomatoes and garlic are roasted, transfer them to the pot with the onions. Be sure to include all those tasty juices from the pan.
Add the vegetable or chicken broth to the pot and bring it to a gentle simmer. Let everything cook together for 10 minutes to meld the flavors.
Remove the pot from heat and add the fresh basil leaves.
Puree the soup: Using an immersion blender, blend the soup directly in the pot until smooth and creamy. Alternatively, carefully transfer batches to a stand blender, blend until smooth, and return to the pot.
Stir in the heavy cream or coconut cream and season with salt, pepper, and optional red pepper flakes or sugar to taste. Warm the soup gently over low heat, but don’t let it boil.
Serve hot, garnished with a few fresh basil leaves or a drizzle of olive oil for an extra touch.

Pro tip: If your soup feels too thick, add a splash more broth or water to reach your desired consistency. The roasting juices carry so much flavor, so don’t skip adding them!

When blending, watch out for steam pressure if using a stand blender—vent the lid slightly and cover with a towel to avoid hot splashes. Also, tasting as you go is key here; sometimes a little more salt or basil can make a big difference.

Cooking Tips & Techniques

Roasting tomatoes is the secret weapon for this soup’s deep, rich flavor. You want them soft and caramelized but not burnt, so keep an eye after 20 minutes. Tossing garlic with the tomatoes lets it mellow and sweeten without getting bitter.

Sautéing the onions slowly is crucial. It brings out their natural sweetness and adds layers of flavor. If you rush this step, the soup might taste flat.

Blending the soup until ultra-smooth makes it so comforting. I’ve made the mistake of not pureeing enough, and the texture felt chunky and less satisfying. Using an immersion blender lets you control the texture perfectly and saves cleanup time.

Be cautious when adding cream—adding it last and warming gently prevents curdling. If you’re dairy-free, coconut cream works beautifully but adds a subtle coconut hint, so keep that in mind.

Lastly, seasoning is everything. I always taste after blending and adjust salt and pepper gradually. Remember, roasting concentrates flavors, so go easy at first and tweak to your preference.

Variations & Adaptations

Dairy-Free Version: Swap heavy cream with canned coconut milk or cashew cream for a luscious, plant-based alternative.
Spicy Kick: Add a pinch of cayenne or a diced jalapeño during the onion sauté for a warming heat that pairs nicely with the sweetness.
Herb Variations: Try swapping half the basil for fresh thyme or oregano to give the soup an earthy twist.
Roasted Red Pepper Addition: For a smoky sweetness, roast a red bell pepper alongside the tomatoes and blend it in.
Low-Carb Option: Skip the cream and use full-fat Greek yogurt stirred in at the end for tangy creaminess with fewer calories.

One of my favorite personal twists was adding a splash of balsamic vinegar right before serving—just a little bit wakes up the flavors and adds complexity without overpowering the soup’s comforting feel.

Serving & Storage Suggestions

This comforting creamy roasted tomato basil soup is best served warm, fresh from the pot. I like to ladle it into rustic bowls and top with a few torn basil leaves or a swirl of cream for a pretty presentation. It pairs wonderfully with crusty bread, grilled cheese sandwiches, or a simple green salad for a well-rounded meal.

Leftovers keep well in the fridge for up to 3 days in an airtight container. When reheating, warm gently on the stove or in the microwave, stirring occasionally to keep the texture smooth. Adding a splash of broth or cream during reheating can help revive the soup if it thickens too much.

You can also freeze this soup for up to 3 months. Just cool completely before transferring to freezer-safe containers. Thaw overnight in the fridge, then reheat slowly. The flavors actually develop beautifully over time, making leftovers a treat!

Nutritional Information & Benefits

Each serving of this comforting creamy roasted tomato basil soup provides roughly 180-220 calories (depending on cream choice), making it a light yet satisfying option. Tomatoes are packed with vitamin C, potassium, and antioxidants like lycopene, which supports heart health and skin vitality.

The fresh basil adds vitamin K and anti-inflammatory properties, while the garlic boosts immune function. Using olive oil brings in healthy monounsaturated fats, which are great for your heart.

This recipe is naturally gluten-free and can easily be adapted for dairy-free or low-carb diets. Just swap the cream and broth as needed. It’s a wholesome, nutrient-rich soup that feels indulgent without the guilt—perfect for nourishing your body and soul.

Conclusion

There’s just something incredibly satisfying about a bowl of comforting creamy roasted tomato basil soup. Between the deep, roasted tomato flavor and the fresh, bright basil, every spoonful feels like a little moment of joy. I hope you give this recipe a try and make it your own by adjusting the creaminess or herbs to suit your mood.

FAQs

Can I use canned tomatoes instead of fresh for this soup?

Yes, you can use high-quality canned whole or crushed tomatoes, but roasting fresh tomatoes really adds a deeper flavor. If using canned, consider roasting them briefly or sautéing with garlic to boost taste.

How can I make this soup vegan?

Simply swap the heavy cream for coconut cream or cashew cream, and use vegetable broth instead of chicken broth. This keeps the soup creamy and delicious without animal products.

Is it necessary to peel the tomatoes before roasting?

Nope! The roasting process softens the skins, and blending makes them unnoticeable. Leaving skins on saves time and adds fiber.

Can I prepare this soup ahead of time?

Absolutely. You can roast the tomatoes and garlic a day ahead, then combine everything and blend when ready. The soup also stores well in the fridge and freezer for later enjoyment.

What’s the best way to store leftover soup?

Store leftovers in an airtight container in the fridge for up to 3 days or freeze for up to 3 months. Reheat gently on the stove, adding a splash of broth if needed to loosen the texture.
