Heat the olive oil in a large pot over medium heat. Add the diced pancetta and cook until it begins to brown and release its fat.
Add the diced onion to the pot and cook until softened. Stir in the minced garlic and cook for another minute.
Pour in the vegetable broth, then add the pumpkin puree, drained white beans, dried thyme, salt, and black pepper.
Bring the mixture to a simmer and cook for 20 minutes, stirring occasionally to prevent sticking.
Taste and adjust salt if needed before removing the pot from the heat.
