What is roasted vegetable gazpacho?
Gazpacho is a Spanish chilled soup, traditionally associated with Andalusia, where it is commonly made from raw vegetables blended with olive oil and vinegar. This version roasts the vegetables first, giving the soup a softer, sweeter flavour and a lightly smoky edge.
Tomatoes provide the familiar gazpacho base, while courgettes make the blend substantial without overwhelming their flavour. Chilling gives the vinegar and roasted vegetables time to come together.

The tomatoes and courgettes contribute most of the carbohydrates, while avocado oil and olive oil account for much of the fat. The vegetables and broth provide some protein, but the amount per serving is modest. Pair a bowl with a protein-rich side, such as eggs or beans, for a more balanced meal.
Choosing and preparing the vegetables
Tomatoes: Use ripe tomatoes for a juicy, savoury base. Quarter them so they roast evenly alongside the other vegetables.
Courgettes and onion: Cut the courgettes into cubes and quarter the onion, as listed, so both soften and take on colour in the oven.
Jalapeño and garlic: Halve the first jalapeño before roasting; the second is sliced for the topping. Keep the seeds if you prefer more heat, or remove them before using.
Roasting for depth
Spread the vegetables in a large skillet or across two smaller pans or a baking tray, leaving them room to roast rather than pile up. Coat them with avocado oil before they go into the oven.
The final 5 minutes under a high grill help form charred spots. Watch closely during this stage, since the vegetables can darken quickly.
Getting a smooth soup
Blend the roasted vegetables until smooth before adding the broth, oil and vinegar. Pulse after adding these liquids to combine them without losing control of the soup’s texture.
Blenders vary in capacity, so work in batches if needed and take care with warm vegetables. The soup should be smooth enough to ladle, with no large pieces remaining.
Why the long chill matters
Chill the blended soup for at least 8 hours before serving. This gives it time to become thoroughly cold and lets the roasted, acidic and savoury flavours settle together.
Make the soup ahead, but leave the cucumber, cilantro and sliced jalapeño until serving so they stay fresh and crisp.
Serving the gazpacho
Serve the soup cold in bowls, topped with thin cucumber slices, cilantro and fresh jalapeño. Flaky salt and freshly ground pepper add a final savoury contrast.
For a more substantial meal, serve it with crusty bread or a simple sandwich. Add these alongside rather than stirring them into the soup, so the chilled texture stays intact.
Recipe notes & tips
- Use two pans if the vegetables do not fit in a single layer.
- Check the vegetables during the high-grill stage so their edges char without burning.
- Taste the soup after chilling and adjust the seasoning before serving.
- Blend in batches if your blender cannot safely hold all the vegetables and liquid.
- Keep the garnishes separate until the bowls are ready to serve.
Variations
- Adjust the heat: Remove the jalapeño seeds before roasting or slicing for a milder soup.
- Add extra herbs: Use more cilantro as a garnish for a stronger herbal note.
- Change the oil: Use another high-heat oil, such as coconut oil, in place of avocado oil.
- Make it chunkier: Blend the soup briefly, stopping before it becomes completely smooth.
- Serve with bread: Add crusty bread alongside the soup for a more filling meal.
Common mistakes to avoid
- Crowding the pan: The vegetables may steam instead of roast; divide them between pans or use a baking tray.
- Skipping the char: The soup will lose some roasted depth; give the vegetables the full 5 minutes under a high grill, watching closely.
- Blending too much at once: A full blender can be difficult to handle; work in batches if necessary.
- Serving it too soon: The flavours and temperature need time to settle; chill for at least 8 hours.
- Adding the garnish early: Cucumber and cilantro can lose their fresh texture; add them just before serving.
How to store
Keep the soup covered in the refrigerator for up to 3 days, storing the garnishes separately. Stir before serving; this soup is intended to be eaten cold, so no reheating is needed.
Frequently asked questions
Can I make roasted vegetable gazpacho ahead?
Yes. Blend and chill it for at least 8 hours, then add the cucumber, cilantro and sliced jalapeño just before serving.
How can I make the soup less spicy?
Remove the seeds and inner ribs from the jalapeños, or use less of the sliced jalapeño as a topping.
Can I use a baking tray instead of a skillet?
Yes. The method allows for a sheet pan; use two pans if necessary so the vegetables are not crowded.
Should the vegetables cool before blending?
The method transfers them after roasting, but take care when blending warm ingredients. Follow your blender’s instructions and work in batches if needed.
Can I serve this soup warm?
It is designed to be chilled for at least 8 hours and served cold. Chilling is part of the preparation, not just a serving preference.
