Roasted Tomato Soup

September 12, 2021

Roasted Tomato Soup is made with oven roasted heirloom tomatoes, garlic and caramelized onions to give you a rich, flavorful bowl! Pair it with grilled cheese for the ultimate comfort food meal! 

Tomato soup is a classic that everyone loves! From the early days of childhood all the way to adult hood, there’s nothing like pairing a big bowl of tomato soup with crusty bread or a gooey grilled cheese! Today I’m bringing a deeper richness to this classic by roasting the tomatoes! The caramelization that occurs in the oven when tomatoes are roasted is magical, and brings incredible flavor to this roasted tomato soup! Additionally, when tomatoes are roasted, they become more concentrated, and intense, because there’s less liquid per bite.

How long do you roast tomatoes in the oven?

To prepare the tomatoes for roasting, give them a light wash, then cut the tomatoes into halves. Spread the tomatoes and garlic cloves on a baking tray. Drizzle with olive oil and season with salt, pepper and thyme. Roast for 20 to 30 minutes, or until they begin to caramelize.

How do you make roasted tomato soup?

Heat a large stock pot on the stove over medium heat.

Slice an onion and add to the pot with 3 tablespoons of olive oil. Cook until caramelized, about 10 minutes.

Add stock, bay leaf and butter. Add roasted tomatoes and garlic.

Bring to a boil, reduce heat and simmer for 15 to 20 minutes or until liquid has reduced by a third.

Remove the bay leaves and thyme and using an immersion blender, blend until smooth.

Return soup to low heat and add basil, grated parmesan, and salt and pepper to taste.

Tips for making the best tomato soup

  • Add fresh basil, not dried. Fresh herbs always perk up a soup
  • Use freshly grated parmesan cheese. Freshly grated parmesan is always better than the powdered stuff.
  • Add Croutons. My homemade garlic parmesan croutons are a yummy garnish for this roasted tomato soup.
  • Drizzle with an infused olive oil. Take a squirt bottle or put a pour spout on a bottle of olive oil and create a circle on the top of your soup for extra flavor and a beautiful garnish!

How can I freeze tomato soup?

If you make a big batch and have soup left over, roasted tomato soup is great for freezing. Fully cook and fully cool the roasted tomato soup. Freeze in a freezer container or bag and seal well. You can store it for up to three months in freezer. To reheat, thaw in the refrigerator or using the defrost setting in the microwave.
