This Provençal vegetable soup, known traditionally as soupe au pistou, is a vibrant celebration of kitchen garden produce. A staple of Southern France, this vegetarian dish relies on a base of tender leeks, carrots, and potatoes, lightened by the addition of fresh green beans, courgettes, and Swiss chard. Unlike its Italian cousin minestrone, this soup is defined by the pistou—a fragrant, nut-free basil and garlic sauce that is stirred in just before serving to provide a bright, punchy finish.
Perfect for a light lunch or a comforting evening meal, this nourishing soup is as healthy as it is flavourful. The inclusion of pasta shells and edamame beans provides a satisfying bite and a boost of plant-based protein. For the most authentic experience, serve it in wide bowls with the remaining cheesy herb paste swirled through and plenty of crusty, grilled baguette on the side to soak up every last drop.

How to make Provençal Vegetable Soup (Soupe au Pistou)
Cook leek, celery, carrot, garlic, and thyme sprig in oil with 1/2 teaspoons salt and 1/4 teaspoons pepper in a 5-to 6-quart heavy pot over medium heat, stirring occasionally, until vegetables brown and stick to bottom of pot, 10 to 15 minutes.
Add potatoes and chard stems with 1/2 teaspoons salt and cook, stirring occasionally, until beginning to soften, about 5 minutes. Add water and bring to a boil, stirring and scraping up brown bits.
Stir in edamame, courgette, green beans, pasta, chard leaves, and 1/4 teaspoons salt and simmer, uncovered, until pasta is al dente and vegetables are tender, about 10 minutes. Discard thyme sprig.
Heat a dry small skillet (not nonstick) over medium heat until hot, then char tomato on all sides. Core tomato, then purée with basil, parsley, and garlic in a food processor. Add oil and cheese and blend well.
Remove soup from heat and stir in half of pistou and salt and pepper to taste. Serve soup with remaining pistou.
