Roasted Olive Tomato Soup: Take Traditional Tomato Soup to Another Level
It’s officially soup season and there are so many delicious ways to enjoy it! Soup is a great way to warm you up from within and most of them are pretty easy and fuss-free. It’s also easy to get creative with new flavors and ingredients when making soup.
What’s more comforting on a winter day than a good old tomato soup served with grilled cheese? I can’t think of anything better. We do have beautiful winter tomatoes, but I feel like they need something extra to really come through. Enter: olives! Roasting olives with the tomatoes will really bring out that umami flavor and just a perfectly balanced hint of the briny, salty olives.

I’m a big fan of using olives in cooked foods. You can let them simmer in slow-cooked stews, grill them, fry them or roast them like we’re doing today. They’re perfect for the winter season when we want to bring out more flavors of the produce we’re working with.
Ingredients You’ll Need

- Vegetables: Tomatoes, Pitted big green olives, Garlic, Shallots
- Herbs: Fresh thyme, Basil leaves, Dried oregano, Dried basil
- Condiments: Olive oil, Tomato paste, Vegetable stock, Salt, Pepper, Chili flakes, Sugar (if you have tomatoes with high acid).
- Dairy alternatives: Vegan (heavy) cream
- To serve: Vegan grilled cheese or other bread.
How to Make This Roasted Olive Tomato Soup

Prepare the tomatoes and garlic
Preheat the oven to 200 C / 390 F. If you are using large tomatoes, cut them in half. Cut off the top part of the garlic head.
add the ingredients to a baking tray
Place the tomatoes, garlic, shallots, thyme and olives on a baking tray. Drizzle over 2 tablespoons of olive oil, season with salt and pepper. Make sure the thyme is tucked under the tomatoes or olives so it doesn’t burn. Place the garlic with the cut side down.
roast the vegetables

Roast in the oven for 40-50 minutes until everything is tender.
bring it all together


Heat 1/2 tablespoon of olive oil in a large pot and stir-fry the tomato for 1 minute. Add all roasted vegetables (squeeze the garlic cloves out of the skin and remove tomato sprigs), basil leaves, vegan cream, vegetable stock, oregano, basil pepper and chili flakes.


Blend the soup until smooth and let simmer for a couple of minutes. Adjust with more stock if you want it thinner. Finally season with salt after tasting it, as both the olives and the broth are savory.
