01 - Heat olive oil in a large pot over medium heat. Add the diced onion and cook for 3 to 4 minutes until softened and translucent.
02 - Add the minced garlic and stir for 1 minute until fragrant, being careful not to let it brown.
03 - Stir in the tomato paste and cook for 1 minute, allowing it to caramelize slightly and deepen in color.
04 - Add the diced tomatoes, drained white beans, vegetable broth, dried basil, oregano, and smoked paprika. Stir thoroughly to combine all ingredients.
05 - Bring the mixture to a gentle boil, then reduce the heat to low and simmer uncovered for 15 to 20 minutes, allowing the flavors to meld and the soup to thicken slightly.
06 - Remove the pot from heat. Use an immersion blender to puree the soup directly in the pot until smooth and creamy. Alternatively, transfer the soup in batches to a countertop blender and blend until silky.
07 - Stir in the Greek yogurt until fully incorporated and the soup reaches a creamy, uniform consistency. Season with salt and black pepper to taste.
08 - Ladle the soup into bowls and garnish with fresh basil leaves, a swirl of Greek yogurt, and a sprinkle of pumpkin seeds if desired.
