How to Make Roasted Tomato Soup

Place the halved tomatoes cut side up onto a baking sheet along with the sliced onions.

Drizzle in oil and add in the garlic, salt, and pepper.

Roast in the oven for 40-50 minutes.

Place everything into a blender and add in your milk, parmesan cheese, basil, tomato paste, and sugar.

Puree until smooth.

Serve warm and enjoy!

Substitutes

Tomatoes. We are roasting the tomatoes and onions to help bring out the natural sweetness and remove excess moisture. You can use other tomatoes like cherry or grape tomatoes but keep in mind that you will need several cups worth as they are much smaller than a Roma tomato.
Cream. If you would like to use heavy cream, evaporated milk, or half and half instead of the milk you may. You can even choose to use non-dairy milk if desired as the results will still taste good. Alternatively, you can use chicken or vegetable broth but this will give you a less creamy soup.

Recipe Tips

If needed work in batches. Not all blenders can hold in the same amount of stuff so you may need to work in small batches, placing the pureed soup into a pot over low heat while working with the remaining batches until completed. Then stir together before serving.
Food processors work great too. If desired you can use a food processor instead of a blender to help get your soup to a nice and smooth finish.
Sugar in soup. We add a little bit of granulated sugar to this soup to help lower the acidity. Sugar helps to neutralize and balance out some of that tangy tomato taste and leave behind the wonderful flavor of sweet cooked tomatoes instead.

FAQs

Is tomato soup gluten-free?

This soup recipe is naturally gluten-free and vegetarian. By swapping out the milk for a non-dairy option you can also make this soup dairy-free and vegan-friendly as well.

How much oil do I need for roasting tomatoes?

You will only need about 2-3 Tbsp of oil to help cover and coat the tomatoes before roasting. Using canola or vegetable oil is actually preferred over olive oil but you can use what you have on hand.

Can I freeze roasted tomato and basil soup?

If you use evaporated milk or heavy cream then yes, you can freeze this soup after it cools. Other dairy products in the soup like regular milk or half and half will not turn out as well once thawed. If planning on making this soup for a freezer meal I recommend freezing the soup without the milk added and then thawing the soup to add it in just before serving as this will give you the best results.
You can freeze this soup in an airtight container for up to 3 months.
