How to Make Roasted Tomato Basil Soup

For the Roasted Tomatoes:

Preheat Oven: Preheat to 400°F (200°C) and position an oven rack in the center. High heat unlocks tomato sugars for deep caramelization and intensified, sweet flavor.
Toss Vegetables: On a rimmed baking sheet, toss halved tomatoes and peeled garlic cloves in olive oil, salt, and freshly ground black pepper, ensuring each piece is evenly coated.
Roast: Bake tomatoes and garlic for 25–30 minutes, stirring once halfway through. Aim for tender, collapsing tomatoes, slightly charred skins, and golden-brown garlic for rich, mellow depth.

For the Soup Base:

Sauté Onion: In a large pot over medium heat, warm olive oil and cook chopped onion until soft and translucent, about 5 minutes, to build a savory foundation.
Combine: Add roasted tomatoes with their pan juices and vegetable broth to the pot. Stir, bring to a gentle boil, then reduce heat and let the flavors marry.
Simmer: Let the soup simmer gently for 10 minutes, stirring occasionally. If it becomes too thick, add extra broth or water to reach your preferred consistency.
Blend: Carefully puree the hot soup with an immersion blender until silky smooth, or blend in batches in a countertop blender. Return to low heat to warm through.
Season: Stir in fresh basil leaves, seasoning with salt, freshly ground pepper, and a pinch of sugar if needed to balance tomato acidity.
Serve: Ladle steaming soup into bowls, top with extra basil leaves, and finish with a crack of black pepper. Enjoy alongside crusty bread for a truly cozy meal.

Optional: swirl in heavy cream or coconut milk for extra silky richness.

Expert Tips for Roasted Tomato Basil Soup

Choose ripe tomatoes: Use vine-ripened tomatoes for the best natural sweetness and flavor that intensifies when roasted.
Don’t skip roasting: Roasting unlocks deep caramelized flavors, avoiding a bland, acidic soup. Be patient for those golden edges.
Blend carefully: Use an immersion blender for silky texture; over-blending can warm soup too much and dull fresh basil’s brightness.
Balance acidity: Add a pinch of sugar only if the roasted tomatoes taste too sharp, preserving the soup’s natural brightness.
Fresh basil last: Stir basil in at the end to maintain its vibrant, herbal aroma and avoid bitterness.
Serve warm with sides: Pair the soup with crusty bread or a light salad for a complete, comforting meal that highlights the roasted tomato basil soup’s richness.

Roasted Tomato Basil Soup Recipe FAQs

What kind of tomatoes work best for Roasted Tomato Basil Soup?
For the richest flavor, I recommend vine-ripened tomatoes that are firm yet fully colored. Avoid underripe (greenish) or overly soft tomatoes with dark spots all over, as they won’t caramelize properly when roasted.

How long can I store leftover Roasted Tomato Basil Soup in the refrigerator?
Leftovers keep beautifully in the fridge for 3 to 4 days when stored in an airtight container. Make sure the soup has cooled completely before sealing it, to prevent condensation which can affect flavor and texture.

Can I freeze Roasted Tomato Basil Soup and how should I do it?
Absolutely! Freeze the soup in freezer-safe containers or heavy-duty freezer bags, leaving at least 1 inch of headspace for expansion. Portioning into individual servings is ideal. Label with the date and freeze for up to 3 months. When ready to enjoy, thaw overnight in the fridge and gently warm it on the stove over low heat, stirring occasionally.

What should I do if my soup tastes too acidic after roasting the tomatoes?
No worries! A small pinch of sugar stirred in at the end of cooking works wonders to balance acidity without overpowering the fresh tomato flavor. Taste as you go, adding a little at a time until the soup’s bright and smooth to your liking.

Is this Roasted Tomato Basil Soup safe for pets?
While the soup’s ingredients are wholesome for us, ingredients like garlic and onion used in this recipe are toxic to dogs and cats. It’s best not to share this soup with your furry friends and keep them away from any leftovers.
