How to Make Roasted Tomato & Basil Soup

For Roasting Tomatoes & Garlic:

Preheat your oven to 400°F and line a baking sheet with parchment paper. This ensures even roasting for sweet, caramelized tomatoes and garlic, enhancing their natural smoky depth.
Roast halved Roma tomatoes and peeled garlic cloves for 25 minutes, until edges brown lightly and juices bubble. Rotate the pan halfway for uniform color and intensified flavor in every piece.

For Simmering Soup:

Sauté chopped onion in a saucepan over medium heat with a drizzle of olive oil, stirring for about 5 minutes, until translucent and fragrant, adding depth and balancing the soup’s acidity.
Combine roasted tomatoes, garlic, sautéed onions, and low-sodium broth in the pot, bringing the mixture to a gentle simmer over medium-low heat for 10 minutes to meld all flavors.

For Blending & Finishing:

Blend the warm soup in batches using an immersion blender or a countertop blender, pulsing until smooth and creamy, and watch the color turn vibrant orange-red with a silky texture.
Stir in heavy cream or coconut milk over low heat, fold in torn basil leaves, then season with sea salt and freshly ground pepper to taste for a balanced, indulgent finish.
Serve hot in warmed bowls, garnishing each with a drizzle of olive oil or a sprinkle of Parmesan, and enjoy cozy comfort balanced with bright basil freshness.

Optional: Garnish with extra basil and a drizzle of olive oil.

Roasted Tomato & Basil Soup Recipe FAQs

How do I select the best tomatoes for Roasted Tomato & Basil Soup?
Choose ripe Roma tomatoes that are firm with glossy skin and no dark spots. Avoid overripe or mushy tomatoes, as they can lead to a watery or bland soup. Firm, evenly colored tomatoes roast beautifully, bringing out that natural sweetness and vibrant flavor.

What’s the best way to store leftover soup, and how long will it keep?
Store any leftover soup in an airtight container once it has cooled completely. Keep it refrigerated for up to 3 to 4 days. For the freshest taste, reheat gently on the stove and add fresh basil or cream to brighten the flavor before serving.

Can I freeze Roasted Tomato & Basil Soup? If so, how?
Absolutely! Freeze the soup without cream or fresh basil added to maintain peak freshness. Portion the soup into freezer-safe containers or heavy-duty freezer bags, leaving about an inch of headspace for expansion. Label and freeze for up to 3 months. When ready, thaw overnight in the fridge and gently warm on the stove, then stir in cream and fresh basil just before serving.

What should I do if my soup tastes too acidic or bitter after roasting?
No worries! A common fix is to balance the acidity by adding a teaspoon of sugar or a splash of cream slowly while stirring. You can also add a pinch more salt, which enhances sweetness and reduces sharp edges. Sautéing the onions gently before adding them helps mellow the flavors, so never rush that step.

Is this soup safe for pets or people with allergies?
While this soup is delicious for humans, it’s not recommended for pets due to garlic and onion, which are toxic to dogs and cats. For those with dairy allergies, swap heavy cream with coconut milk or your preferred non-dairy alternative to keep it creamy without the allergens. Always double-check ingredient labels to suit specific dietary needs.
