Begin by preheating the oven to 475°F (245°C).
While the oven’s heating, rub olive oil over the bell peppers.
Once the oven is ready, roast the red bell peppers for about 25-30 minutes. Turn them occasionally to ensure even roasting.
When the skin becomes charred, remove the peppers from the oven and let them cool.
After cooling, peel off the skin and discard the seeds and stems.
In a large pot, heat the remaining olive oil over medium heat.
Add chopped onions, and sauté until translucent, approximately 5-7 minutes.
Throw in the minced garlic and sauté for an additional 2 minutes.
Add the roasted red bell peppers, diced tomatoes, cumin, paprika, salt, and pepper.
Pour the vegetable broth into the pot.
Let the mixture simmer for about 15-20 minutes.
Using a hand blender, blend the soup until it reaches a smooth consistency. If it’s too thick, add more vegetable broth until desired consistency is achieved.
Taste the Vegan Roasted Red Pepper Soup and adjust seasonings if necessary.
Serve hot and, if desired, garnish with fresh basil or cilantro.
