Creamy Flavor-Packed Green Tomato and Kale Soup
Green tomatoes are hard to come by where I live, so every visit to London turns into an opportunity to bring back a generous stash.
After discovering how delicious green tomato jam and a vibrant salsa verde can be, I’ve grown quite fond of their bright, distinctive taste.
With a few tomatoes left, I decided to make a creamy soup with kale, loosely inspired by a recipe I once stumbled upon on an American blog.
I was a bit hesitant the first I made it, worried the flavor might be too sharp or overly acidic.
To soften it, I added a potato for natural sweetness and a smoother texture, and I loved the finish it gave.
I also stirred in a little baking soda, a simple trick I’d read about to tame acidity.
The result was a velvety, comforting, beautifully balanced soup I know I’ll return to often.

Ingredients for a Nourishing and Flavorful Green Tomato Soup
- 1 kg green tomatoes, quartered : Their bright tang softens beautifully when roasted, creating a deep, mellow flavor.
- 2 medium onions, quartered : They caramelize in the oven and add gentle sweetness to the soup.
- 5 garlic cloves : Essential for warmth, aroma, and depth of flavor.
- 2 tbsp olive oil : Helps the vegetables roast evenly and enhances their natural taste.
- ½ tsp fine salt : Just enough to season the vegetables without overpowering the delicate flavors.
- ¼ tsp black pepper : Adds a subtle spicy note that complements the tomatoes.
- 2 cups chopped kale : Boosts nutrients, adds color, and rounds out the soup with earthy notes.
- 1 potato, diced : Softens acidity and naturally thickens the soup for a velvety finish.
- 1 cup vegetable or chicken broth : Provides the liquid base and helps blend all the flavors together.
- ½ tsp baking soda : Neutralizes excess acidity and creates a wonderfully balanced taste.
- ½ cup cream (optional) : For extra richness and a smooth, luxurious texture.

Step-by-Step Instructions for the Perfect Roasted Green Tomato Soup
1. Roast the vegetables for maximum flavor
- Preheat the oven to 220°C / 425°F.
- Spread the green tomatoes, onions, and garlic cloves on a baking tray.
- Drizzle with olive oil and season with salt and pepper.
- Roast for 15 minutes, flip the tomatoes, then roast for another 15 minutes, until lightly browned and caramelized.
2. Simmer the broth and vegetables
- In a pot, gently simmer the broth with the diced potato and chopped kale.
- Cover and cook for 10 minutes, until everything is tender and fragrant.
3. Blend and balance the acidity
- Add the roasted vegetables to the pot.
- Blend until completely smooth and creamy.
- Return the soup to the pot, on a medium heat and stir in the baking soda; it will foam slightly as it neutralizes acidity.
- Mix until the bubbles fade completely.
- Adjust seasoning, then stir in the cream if you’d like a richer texture.
4. Serve with a flavorful finishing touch
- Ladle the soup into bowls while hot.
- Finish with a drizzle of olive oil, cracked black pepper, or a swirl of cream.

How to Reduce Acidity in Green Tomato Soup
Green tomatoes are naturally more acidic, but you can easily create a smooth, balanced flavor by using:
- A potato to add natural sweetness
- Roasting, which caramelizes the sugars
- A pinch of baking soda, which neutralizes acidity
- Cream, for those who prefer a richer, rounder finish
