Preheat your oven to 400°F (200°C).
Cut the top off the garlic bulb to expose the cloves slightly. Drizzle 1 tablespoon of olive oil over the top, wrap the bulb in aluminum foil, and roast in the oven for 35–40 minutes, or until the cloves are soft and golden brown.
While the garlic roasts, peel and dice the potatoes into 1-inch cubes. Set aside.
Trim the leeks, discarding the dark green tops. Slice the white and light green parts into thin rounds, then rinse thoroughly to remove any grit.
In a large pot, heat the remaining 1 tablespoon of olive oil and butter over medium heat. Add the leeks and sauté for 5–7 minutes, or until they become soft and slightly translucent.
Squeeze the roasted garlic cloves out of their skins and add them to the pot with the sautéed leeks.
Add the diced potatoes, vegetable broth, salt, black pepper, and thyme to the pot. Bring the mixture to a boil, then reduce the heat to low and simmer for 20–25 minutes, or until the potatoes are very tender.
Remove the pot from heat. Use an immersion blender to puree the soup until smooth. Alternatively, blend the soup in batches in a countertop blender, then return it to the pot.
Stir in the heavy cream and adjust the seasoning with additional salt and pepper, if needed. Heat the soup gently over low heat without letting it boil.
Ladle the soup into bowls, garnish with chopped fresh parsley, and serve warm with crusty bread or croutons.
