The Essence of Spring Pistou Soup

A French Classic with a Springtime Twist

Spring Pistou Soup, often called Soupe au Pistou, is a Provençal vegetable soup known for being both rustic and elegant. Traditionally made with seasonal produce and topped with pistou (a mixture of basil, garlic, and olive oil), it’s France’s answer to Italy’s minestrone. In this spring variation, white and green asparagus take the spotlight, creating a light, golden broth that’s full of freshness.

Why Pistou Makes It Special

Pistou is a French condiment similar to pesto but without nuts or cheese. It’s made by blending fresh basil, parsley, garlic, and olive oil into a smooth, aromatic paste. When stirred into the soup just before serving, it infuses each spoonful with a burst of herbal richness. The balance between the earthy vegetables and the bright pistou gives this dish its unique personality.

A Wholesome, Nutrient-Rich Soup

This soup isn’t just delicious—it’s packed with goodness. Asparagus and cauliflower bring vitamins A and C, while peas add fiber and natural sweetness. The homemade broth, made by simmering asparagus peels, is full of flavor and nutrients. Combined with olive oil and fresh herbs, it’s a light yet satisfying meal that supports both health and comfort.

Sustainability in Every Step

One of the best parts of Spring Pistou Soup is its no-waste approach. Instead of discarding asparagus peels, they’re simmered to create a delicate, aromatic broth. This not only reduces waste but also adds incredible depth of flavor—a true reflection of thoughtful, sustainable cooking.
