01 - Heat olive oil in a large pot over medium heat. Add diced onion and cook for 3–4 minutes until translucent and softened.
02 - Add minced garlic to the pot and cook for 1 minute until fragrant, stirring constantly to prevent browning.
03 - Stir in tomato paste and cook for 1 minute, allowing it to caramelize slightly and deepen in color.
04 - Add diced tomatoes, drained white beans, vegetable broth, dried basil, oregano, and smoked paprika. Stir thoroughly to combine all ingredients.
05 - Bring the soup to a gentle boil, then reduce heat to low and simmer uncovered for 15–20 minutes, allowing the flavors to meld together.
06 - Remove the pot from heat. Use an immersion blender to purée the soup directly in the pot until smooth and creamy, or transfer in batches to a countertop blender.
07 - Stir in the Greek yogurt until fully incorporated and the soup reaches a silky 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.
