- 4 cloves garlic cloves minced
- 1 large onion chopped
- 2 tablespoons olive oil for roasting and finishing
- 1 teaspoon dried thyme or other herbs of choice

Chop the tomatoes into halves or quarters, and roughly chop the onion. Toss both with a tablespoon of olive oil to coat evenly.
Spread the prepared tomatoes and onion in the bottom of the slow cooker, adding the minced garlic and thyme on top.
Cover and cook on low for about 6 hours, until the tomatoes are deeply softened and the mixture is fragrant with roasted smells.
Once cooked, use a ladle to transfer the warm mixture into a blender or carefully use an immersion blender directly in the slow cooker to puree until smooth.
Pour the pureed soup back into the slow cooker or a pot; stir in the remaining olive oil, and season with salt and pepper to taste.
Add a splash of vinegar or lemon juice to brighten the flavor; stir well and taste adjust the seasoning if needed.
Heat the soup just until warmed through, then ladle into bowls and serve with crusty bread or a drizzle of olive oil for extra richness.
