This roasted red pepper soup is lightly creamy, comforting, and flavorful. It's easy to make with pantry ingredients like jarred roasted peppers, tomato paste, and vegetable broth. Save any leftovers for lunch the next day—the flavors just get better as this soup sits in the fridge.
Heat 2 tablespoons of the olive oil in a large pot over medium heat. Add the onion and pinches of salt and pepper and cook until translucent, about 5 minutes.
Add the garlic, fennel, carrots, and thyme leaves. Stir and cook until the carrots begin to soften, about 10 minutes.
Add the balsamic vinegar, red peppers, beans, tomato paste, broth, and ½ teaspoon salt. Simmer until the carrots are tender, 15 to 20 minutes.
Allow to cool slightly, then transfer the simmered soup to a high-speed blender with the remaining 2 tablespoons olive oil and puree until smooth. (Alternatively, use an immersion blender to blend the soup in the pot.)
Season with more salt and pepper, to taste. If you would like more punch, add a few more drops of balsamic, to taste. If you would like a little heat, add ½ teaspoon red pepper flakes.
Serve with generous drizzles of olive oil, desired garnishes, and warm baguette.
