This hearty Longevity Soup recipe draws inspiration from the Blue Zones where people live the longest, healthiest lives. Packed with nutrient-dense vegetables, beans, and leafy greens, this nourishing minestrone-style soup delivers exceptional flavor while supporting your wellbeing with every spoonful.
I first created this soup after researching the eating patterns of centenarians around the world. What started as a health experiment quickly became a family favorite that my children request regularly even though it's loaded with vegetables they might otherwise resist.

Step-by-Step Instructions
- Sauté the Base Vegetables
- Heat olive oil in a large Dutch oven over medium heat then add onion carrots celery and zucchini with a pinch of salt. Cook for a full 5 minutes stirring occasionally to develop flavor without browning. The vegetables should begin to soften but maintain some texture.
- Add Sweet Potato and Aromatics
- Incorporate diced sweet potato ensuring pieces are uniform for even cooking. Add minced garlic and cook for just one minute longer. Garlic burns easily and becomes bitter if cooked too long so keep a close eye during this step.
- Layer in Seasonings and Tomato
- Sprinkle in dried thyme and oregano crushing slightly between your fingers to release oils. Add tomato paste and stir continuously for 30 seconds to slightly caramelize which deepens the flavor profile.
- Build the Soup Base
- Pour in vegetable broth and diced tomatoes with their juice. Add your beans and lentils stirring thoroughly to incorporate all ingredients. Season again with salt which helps layer flavor throughout the cooking process.
- Simmer to Develop Flavors
- Add bay leaves and bring everything to a gentle boil before reducing to a simmer. Cook uncovered for 20 minutes allowing the flavors to meld and the vegetables to become tender but not mushy.
- Cook the Pasta
- Add your chosen small pasta shape directly to the soup. The pasta will absorb liquid as it cooks so add extra broth if needed for your preferred consistency. Cook for 10 minutes or until the pasta reaches al dente texture.
- Finish with Greens
- Stir in the kale and spinach just before serving and cook only until wilted about one minute. This preserves their vibrant color nutrients and slight texture which adds freshness to the finished soup.
- Garnish and Serve
- Ladle the hot soup into bowls and finish with a drizzle of extra virgin olive oil fresh parsley and a light sprinkle of parmesan if desired. These final touches elevate the flavor and presentation significantly.

The sweet potato is my secret ingredient in this recipe. While not traditional in Italian minestrone its natural sweetness balances the acidity of the tomatoes perfectly. My grandmother always said a truly healing soup needs something from under the ground and sweet potato fulfills that wisdom beautifully.
Perfect for Meal Prep
This Longevity Soup actually improves with time as the flavors continue to develop in the refrigerator. Make a large batch on Sunday and enjoy nourishing meals throughout the week with minimal effort. Store in airtight containers in the refrigerator for up to 5 days. The pasta will continue absorbing liquid so you might need to add a splash of broth when reheating.
Adaptable to Seasons
One of the beautiful aspects of this soup is how easily it adapts to seasonal produce. In summer swap zucchini for yellow squash and add fresh cherry tomatoes. Fall calls for butternut squash instead of sweet potato plus a handful of chopped kale. Winter versions work beautifully with hearty cabbage and extra herbs. This flexibility makes it a yearround staple that never becomes monotonous.
Serving Suggestions
Transform this soup into a complete meal by serving with a slice of crusty whole grain bread brushed with olive oil and rubbed with garlic. For a protein boost add a softboiled egg on top just before serving or include a simple side salad dressed with lemon juice and olive oil. For special occasions serve in bread bowls for an impressive presentation that delights guests while still maintaining the healthful integrity of the meal.

Recipe Q&A
- → What makes this soup a 'Blue Zones' inspired dish?
This soup incorporates key dietary principles from the world's Blue Zones—regions where people live exceptionally long, healthy lives. It features plant-based proteins from beans and lentils, abundant vegetables, whole grains from pasta, and heart-healthy olive oil—all staples in these longevity hotspots. The combination of ingredients provides a nutrient-dense meal with anti-inflammatory properties and complex carbohydrates that support overall health and longevity.
- → Can I use different beans or legumes in this soup?
Absolutely! The soup is incredibly versatile when it comes to legumes. While the original calls for cannellini beans and lentils, you can substitute with black beans, chickpeas, kidney beans, or any combination of legumes you prefer. This flexibility allows you to work with what's in your pantry while still maintaining the protein-rich, fiber-packed foundation that makes this soup so nourishing.
- → Is this soup freezer-friendly?
Yes, this soup freezes exceptionally well. For best results, cool the soup completely before transferring to freezer-safe containers. Consider freezing without the pasta and adding freshly cooked pasta when reheating to prevent it from becoming mushy. When ready to enjoy, thaw overnight in the refrigerator and gently reheat on the stovetop, adding a splash of broth if needed to reach your desired consistency.
- → How can I make this soup more filling?
While already quite substantial, you can increase the heartiness by doubling the beans or lentils for extra protein and fiber. Adding more pasta or including whole grains like farro or barley will make it even more satisfying. For non-vegetarians, adding some shredded chicken or turkey would work well. Serving with a slice of whole-grain bread drizzled with olive oil on the side creates a complete, filling meal.
- → What are the best greens to use in this soup?
Kale and spinach work wonderfully as specified, but you can experiment with other leafy greens based on availability and preference. Swiss chard, collard greens, or escarole are excellent alternatives that hold up well in soup. For a milder flavor, try baby kale or arugula. Remember that heartier greens like mature kale or collards may need slightly longer cooking time to become tender.
- → Can I make this soup in a slow cooker or Instant Pot?
This soup adapts beautifully to both methods. For slow cooker: Sauté the aromatics first, then combine all ingredients except pasta, kale, and spinach. Cook on low for 6-8 hours or high for 3-4 hours. Add pasta during the final 30 minutes and greens in the last 5 minutes. For Instant Pot: Use sauté function for vegetables, then add ingredients except pasta and greens. Pressure cook for 5 minutes, quick release, then add pasta and cook on sauté until tender. Stir in greens just before serving.
