Instructions

1 Preheat your oven to 400°F (200°C). On a large baking sheet, toss the halved or quartered ripe tomatoes, quartered yellow onion, and unpeeled garlic cloves with 2 tablespoons of olive oil, dried basil, and dried oregano. Ensure everything is lightly coated and spread in a single layer. Roast for 20-25 minutes, or until the tomatoes are softened and slightly caramelized, and the onion is tender and beginning to brown.
2 Once roasted, carefully remove the baking sheet from the oven. Squeeze the softened garlic cloves out of their skins and discard the skins. Transfer the roasted tomatoes, onion, and garlic to a large pot or Dutch oven.
3 Pour in 4 cups of gluten-free vegetable stock. Bring the mixture to a boil over medium-high heat, then reduce the heat to low, cover, and let it simmer gently for about 10 minutes to allow the flavors to meld together.
4 Using an immersion blender, carefully purée the soup directly in the pot until it reaches your desired smooth consistency. Alternatively, transfer the soup in batches to a regular blender, being cautious as hot liquids expand, and blend until smooth, then return to the pot.
5 If using, stir in 1/4 cup of gluten-free heavy cream or full-fat coconut milk for added richness. Season the soup with 1 teaspoon of salt and 1/2 teaspoon of black pepper, or adjust to your personal taste. Heat through for another 2-3 minutes, ensuring it doesn't boil after adding cream.

Tips & Notes

Roast until the tomato edges char in spots. The browned bits give the soup its deep, sweet flavor.
Scrape every bit of juice and browned residue from the baking sheet into the pot. Much of the roasted flavor is there.
If your tomatoes are watery, use meaty Roma or plum tomatoes. They roast down to a richer, thicker soup.
