A deliciously comforting bowl of goodness!
I’m sure I’m not alone in this predicament: I wait months for the tomatoes in my garden to grow and then, all of a sudden, I am overwhelmed by the plants’ abundance. I picked a huge basket of perfectly ripe fruit the other day and realized there were only so many sandwiches and salads I could eat, so I decided to roast some tomatoes and make this soup. I loved it and my husband absolutely raved about the flavour; I’ll be making this one often. If you’re wondering about the inclusion of baking soda, it helps neutralize the tomatoes’ natural acidity and really enhances the flavour. This soup freezes well; I plan to make numerous batches to set aside for a taste of summer on cold winter days. It can be enjoyed warm, at room temperature or cold.

Ingredients
- 3 pounds (1.3 kg) assorted tomatoes *
- 1 large yellow cooking onion
- 4 cloves garlic
- 2 tablespoons (30 mL) olive oil
- Salt and pepper
- 1/2 teaspoon smoked paprika
- Few pinches baking soda
- 1 cup (250 mL) vegetable or chicken broth
- 1/3 cup (20 g) packed fresh basil leaves, torn or chopped
- Optional garnishes: crumbled feta (or vegan alternative) and additional olive oil
*I used a mix of beefsteak, cherry and roma tomatoes
Method
- Preheat oven to 450F. Line a large, rimmed baking tray with parchment paper and set aside.
- Chop tomatoes into pieces of roughly equal size. Since I was using cherry tomatoes, which I halved, I made the other pieces similar in size to them. Peel and chop onion into pieces approximately 1/2 inch (1.25 cm) in size. Peel garlic cloves.
- Put all the vegetables on the prepared baking tray. Drizzle with the olive oil and a few grinds each of salt and pepper then toss to combine well. Bake in preheated oven for 25-30 minutes, until tomatoes are just beginning to blister in places. If garlic cloves are small, remove them from the pan as soon as they are golden brown and softened, and set aside.
- Once vegetables are roasted, transfer them to a large bowl or pot. Stir in smoked paprika, baking soda, fresh basil and broth. Puree the mixture using a stick (immersion) blender, or transfer the mixture (in batches) to a traditional blender and puree until smooth.
- After blending, taste the soup and adjust seasonings to your preference. At this point, the soup can be refrigerated or frozen, or heated and served.
- At serving time, ladle hot soup into bowls and garnish with crumbled feta and/or a drizzle of olive oil.
Serves 4 – 6.

beautiful! Why baking soda?
As the preamble to the recipe notes, baking soda neutralizes the tomatoes’ natural acidity, making for a smoother-tasting finished product. I add a pinch to anything I’m cooking with fresh tomatoes. It’s a tip from a Tuscan cooking school I attended long ago. 🙂
huh. No, I’ve never heard of this! I guess this is why some people add agave or honey? Fresh tomatoes can indeed have a tang. Can’t wait to try this on my next batch. Thanks!!!
I suppose that adding some sweetener would achieve similar results but ‘food chemistry’ says that neutralizing the acid is best (hence the use of a pinch of alkaline baking soda).
Makes total sense!!!
haven’t made this yet but just reading the recipe makes me salivate. I dubb this recipe 5 out of 5 Stars.
Thanks for your kind words! I’m confident your rating will prove accurate if/when you make it. 🙂
Do you ever add cream?
I have not added cream to this soup but I am sure it would taste delicious. You may wish to reduce the amount of broth slightly, to permit the soup to maintain a slightly thickened texture. Please let me know if you try it!
Decided not to tinker with the original today .The soup is just delicious !
So glad you’re enjoying it! I find it really tasty as well.
