Equipment

Ingredients

6-8 large ripe tomatoes
2 red bell peppers
1 whole garlic bulb top trimmed to expose cloves
1-2 fresh red chili peppers (adjust to your preferred level of spiciness)
1 small red onion peeled and halved
2 tbsp olive oil
1/4 cup fresh basil leaves
4 cups vegetable or chicken broth
1 tsp balsamic vinegar
Salt and pepper to taste
1/2 tsp dried oregano
1/2 cup heavy cream (optional for a creamier version)
Grated Parmesan cheese for garnish (optional)

Instructions

Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or foil (optional).
Place the whole tomatoes, whole bell peppers, whole chili peppers, and halved red onion on the baking sheet. Wrap the garlic bulb tightly in foil with a drizzle of olive oil and add it to the baking sheet. Drizzle everything with olive oil and season with salt, pepper, and oregano.

Roast for 40–45 minutes, or until the vegetables are tender, blistered, and beginning to caramelize.
Optional: For a deeper char and smokier flavor, turn the oven to broil for the last 3–5 minutes of roasting. Keep a close eye on the vegetables to avoid burning.
Once cool enough to handle, peel the skins off the tomatoes and peppers if desired. Squeeze the roasted garlic cloves out of their skins.
Transfer all roasted vegetables and garlic to a blender or use an immersion blender in a large pot. Add the basil, oregano, broth, and balsamic vinegar, then blend until smooth. Add more broth to adjust the consistency if needed.
1/4 cup fresh basil leaves, 4 cups vegetable or chicken broth, 1 tsp balsamic vinegar, 1/2 tsp dried oregano
Pour the soup into a large pot if you used a blender. Simmer over medium heat for 10–15 minutes to let the flavors come together.
Stir in the heavy cream if using, just before serving, for a richer texture.
1/2 cup heavy cream
Ladle into bowls and garnish with grated Parmesan and fresh basil, if desired. Serve hot with crusty bread or grilled cheese.

Notes

Roasting the vegetables whole helps retain moisture and intensifies their natural sweetness.
Peeling roasted peppers and tomatoes is optional but improves soup texture.
Strain soup with mesh strainer for a smoother consistency.
Adjust chili peppers based on your preferred spice level—remove seeds for less heat.
Use homemade or low-sodium broth for better control over saltiness.
Soup thickens as it cools; add extra broth when reheating if needed.
Leftovers taste even better the next day as flavors continue to develop.
