Roasting changes everything about tomato soup. The oven concentrates the tomatoes’ natural sugars and adds a gentle caramelized flavor that you simply cannot get from a can. Blended with roasted garlic and onion and finished with a splash of cream, this soup is silky, rich and comforting.
Ingredients
- 3 lb (1.4 kg) ripe tomatoes (Roma or vine-ripened), halved
- 1 large yellow onion, cut into wedges
- 1 whole head of garlic, top trimmed off
- 3 tablespoons olive oil
- 1 1/2 teaspoons salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried thyme or oregano
- 2 cups (480 ml) vegetable or chicken broth
- 1 tablespoon tomato paste
- 1 teaspoon sugar, if needed
- 1/2 cup (120 ml) heavy cream or half-and-half
- A handful of fresh basil leaves
Step-by-Step Instructions
- Prepare to roast. Heat the oven to 400°F (200°C). Arrange the tomatoes cut-side up and the onion wedges on a large rimmed baking sheet. Drizzle the garlic head with a little oil and wrap it in foil, then place it on the sheet.
- Season. Drizzle the tomatoes and onion with the olive oil and sprinkle with salt, pepper and dried thyme.
- Roast. Roast for 40 to 45 minutes, until the tomatoes are soft, wrinkled and slightly caramelized at the edges.
- Combine in a pot. Squeeze the soft garlic cloves out of their skins into a large pot. Add the roasted tomatoes, onions and all the juices from the pan.
- Simmer. Add the broth and tomato paste. Bring to a simmer and cook for 10 minutes to blend the flavors.
- Blend. Add the basil and blend with an immersion blender until very smooth. If using a countertop blender, work in batches, fill it no more than halfway, and vent the lid with a towel over the top to let the steam escape.
- Finish. Stir in the cream. Taste and add sugar only if the soup tastes too acidic, then adjust the salt.
Choosing Tomatoes
Roma tomatoes are meaty with fewer seeds, which produces a thicker soup. Vine-ripened tomatoes are juicier and sweeter. Out of season, two 28-ounce (800 g) cans of whole peeled tomatoes, drained and roasted for 30 minutes, are a good substitute.
Tips for Success
- Scrape the pan. The browned juices on the baking sheet are full of flavor. Add a splash of broth to loosen them.
- For an extra smooth soup, pass it through a fine-mesh sieve after blending to remove the seeds and skins.
- Adjust thickness with more broth if too thick or a few minutes of simmering if too thin.
Variations
- Roasted red pepper: Add two red bell peppers to the baking sheet.
- Dairy-free: Use coconut milk or omit the cream and add an extra tablespoon of olive oil.
- Spicy: Roast a fresh chili with the tomatoes or add a pinch of chili flakes.
Storage and Freezing
Refrigerate for up to 5 days. Freeze for up to 3 months, ideally before adding the cream; stir the cream in after reheating.
Frequently Asked Questions
Do I need to peel the tomatoes?
No. Roasting softens the skins and blending breaks them down. Strain the soup if you prefer a perfectly smooth texture.
Why does my soup taste sour?
Tomatoes vary in acidity. A little sugar, a pinch of baking soda or an extra splash of cream will balance it.
What can I serve with tomato soup?
The classic choice is a grilled cheese sandwich. Croutons, a swirl of pesto, a spoon of Greek yogurt or a sprinkle of Parmesan are all excellent toppings.
