Roasted Tomato Basil Soup

So good far a chilly day!

Total: 1hr 25 min
Cook: 1 hr 10min
Servings: 4 servings


For the roasted tomatoes

3 pounds roma or plum tomatoes, cut in half
8 cloves garlic, peeled
3 tablespoons olive oil
Freshly ground salt and pepper

For the caramelized onions:

½ tablespoon olive oil
2 yellow onions, thinly sliced

Additions to the soup:

½ cup packed basil leaves
½ teaspoon dried oregano
1-2 cups water or vegetarian broth, depending on how thick you want the soup
Freshly ground salt and pepper, to taste
1 cup heavy cream or half & half

Optional add ins:

Whole dairy milk/heavy cream for a creamy texture
Parmesan cheese, for a tangy, flavor enhancing flavor


Preheat oven to 400 degrees F. Line a large baking sheet with parchment paper. Place halved tomatoes and garlic cloves on the baking sheet and drizzle with 3 tablespoons of olive oil. Generously season with salt and pepper. Roast in the oven for 40-45 minutes.

While the tomatoes are roasting, you can make the caramelized onions: Add 1/2 tablespoon olive oil to a large pot and place over medium heat. Add the onion slices and stir to coat the onions with olive oil. Cook, stirring occasionally. Check onions every 5-10 minutes until they have completely caramelized and turned golden in color. This usually takes 20 minutes.

Once tomatoes and garlic are done roasting, allow them to cool for 10 minutes, then add them to a food processor or high-powered blender and blend until smooth. If you have an immersion blender that would be my recommendation.  Next add basil and caramelized onions and blend again. Alternatively, you can add the tomatoes to the large pot and use an immersion blender.

After blending, transfer back to pot, turn to medium low heat and add in oregano, vegetarian broth and salt and pepper to taste. From there you can add in any additional add-ons. I added 1 cup of heavy cream for a cream tomato soup. Allow tomato soup to simmer 10 minutes before serving. To serve, garnish with parmesan cheese and serve with grilled cheese or French bread, if desired. Serves 4.
