This Roasted Tomato and Red Pepper Soup is one of my favorite ways to enjoy fresh summer tomatoes. The tomatoes, red peppers, onion, and garlic are roasted until tender and lightly caramelized, then blended with fresh basil, oregano, and stock into a smooth, flavorful soup.
Roasting the vegetables first makes a big difference. It brings out their natural sweetness and gives the soup a deeper flavor than you get from simply cooking everything in a pot.
Serve it with crispy cheese toasts for an easy lunch or light dinner. The soup is also simple enough to make ahead and freezes well, so you can enjoy it long after tomato season.
Why You’ll Love This Roasted Tomato and Red Pepper Soup

Ingredients
Tomatoes – Use ripe, flavorful tomatoes since they are the main ingredient in the soup. Roma, vine-ripened, or other meaty tomatoes work well.
Red bell peppers – Roasting brings out their natural sweetness and adds depth to the tomato flavor.
Red onion – Adds sweetness and savory flavor as it roasts.
Garlic – Roasting the garlic in its skin makes it soft, mellow, and slightly sweet.
Olive oil – Helps the vegetables roast and adds richness to the soup.
Basil and oregano – Fresh basil and dried oregano give the soup a simple Mediterranean-style flavor.
Chicken or vegetable stock – Use vegetable stock if you want to keep the soup vegetarian.

How to make Roasted Tomato and Red Pepper Soup
Cut the tomatoes into quarters, the red pepper into chunky pieces, and the onion into wedges and transfer to a parchment paper-lined baking sheet. Add the garlic cloves with the skin on. Season with salt and pepper and drizzle with olive oil. Bake in a preheated 400F (200C) oven for about 40-45 minutes. Transfer the cooked vegetables with all the juice into the bowl of a blender. Squeeze in the garlic flesh and add fresh or dried basil and oregano. Blend until smooth. Pour the soup into a pot and add chicken or vegetable stock. Bring to a boil. Serve the soup warm, decorate with cream and basil leaves and serve with cheese toasts.
Roasting the vegetables enhances their flavor, bringing the best out of them. It is one of the best recipes you can try for tomato season to enjoy its sweet summery flavor.

This is absolutely fantastic, great for pre-autumn season. I’m not big fan of this kind of toast, so instead I’ve made regular croutons, and spreaded grated cheese on top of soup – it also worked really well 🙂
Love your recipes, videos and music!!!!!

You can consider leaving the peppers out. The soup will still be delicious.
