【Key Ingredients】
– Main Ingredient: 2 cups dried white beans (soak overnight; yields about 6 cups cooked; if using canned white beans, drain and use about 450g, skipping the cooking step)
– Base Ingredients: 2 tablespoons extra virgin olive oil (about 30ml), 1 large onion (diced, yields about 2 cups/200g), 6 garlic cloves (minced)
– Root Vegetables: 4 celery stalks (diced, yields about 2 cups/200g), 4 medium carrots (peeled and diced, yields about 2 cups/200g)
– Leafy Greens: 16 cups dark leafy greens (Swiss chard, kale, or spinach; raw weight, approximately 4 cups blanched, about 400g)
– Broth & Seasoning: 4-6 cups (approx. 950-1425 ml) chicken or vegetable broth, ¼ cup (approx. 25 g) grated Parmesan cheese, sea salt and black pepper to taste
– Flavor Enhancers: 3 lemons (zest for approx. 1 tbsp, avoiding the white pith to prevent bitterness), 1 cup fresh basil leaves (shredded)
– Optional Toppings: 1 tbsp crushed red pepper flakes (adjust to taste), pesto sauce to taste (for drizzling)
【Preparation Tips】
1. Cooking Dried Beans from Scratch (Key Step)
1. Sort and Soak: Carefully sift dried white kidney beans, removing debris, pebbles, and shriveled beans. Place 2 cups of beans in a large bowl, cover with water 2-3 inches (approx. 5-7.5 cm) above beans, and soak for at least 8 hours or overnight refrigerated to allow beans to absorb water and plump up.
2. Rinse and Drain: After soaking, thoroughly drain the water. Rinse beans repeatedly under cold running water until the water runs clear.
3. Simmer for Flavor: Transfer rinsed beans to a large pot or Dutch oven. Add fresh water to cover beans by about 2 inches (5 cm). Optionally add 1 halved onion, 3 smashed garlic cloves, 1 bay leaf, or a few sprigs of sage/thyme for extra flavor.
4. Simmer with Salt: Bring water to a boil over high heat, then immediately reduce to the lowest setting. Leave the lid slightly ajar for ventilation. Simmer for 1-3 hours (depending on bean freshness). Add salt once beans are half-soft (adding salt too early can cause a hard core), then continue simmering until beans are tender, creamy, and smooth. Drain and set aside.
2. Blanching Leafy Greens (Preserving Color and Nutrients)
Using Swiss chard as an example: After washing the leaves, separate the stems from the leaves. Cut stems into small sections and tear leaves into bite-sized pieces. Bring a pot of lightly salted water to a boil. Blanch the stems for 1-2 minutes, then add the leaves and blanch for 30 seconds to 1 minute, until tender yet still crisp. Immediately transfer to ice water to stop cooking and prevent over-softening. Drain thoroughly and squeeze out excess water before setting aside.
【Preparation Steps】
1. Sauté the base ingredients: Heat a deep pot or soup pot over medium heat. Add extra virgin olive oil. Once hot, add diced onion and stir-fry for 3-4 minutes until translucent and softened. Add minced garlic and continue stir-frying for 30 seconds until fragrant and lightly golden (avoid burning to prevent bitterness).
2. Simmer vegetables until tender: Add diced carrots and celery, stir-frying for 2 minutes to coat evenly with oil. Pour in 4 cups chicken or vegetable broth. Bring to a boil over high heat, then reduce to low. Cover and simmer for 10-15 minutes until carrots are fork-tender.
3. Blend Flavors: Add cooked white beans and continue simmering on low heat for 5-10 minutes, allowing the beans to fully absorb the broth’s flavor. Optionally add crushed red pepper flakes for added depth.
4. Season and Finish: Stir in grated Parmesan cheese, lemon zest, and shredded basil. Season with salt and black pepper to taste, mix well, then remove from heat. Add blanched leafy greens to the pot. Use the residual heat to warm the greens to tender-crisp perfection, avoiding overcooking that destroys nutrients.
5. Adjust and Serve: Thin the soup to desired consistency with reserved broth. Ladle into bowls, drizzle with pesto or olive oil, and garnish with extra chopped basil and Parmesan shavings before serving.
