Melt the butter in a large pot over medium heat, add the sliced leeks and chopped onion, and cook for several minutes until they are soft, tender, and fragrant without letting them brown too much.

Stir the minced garlic into the softened vegetables, then add the potatoes, thyme, salt, pepper, and broth, bringing everything to a gentle boil so the flavors can begin to come together.

Step 4: Simmer and blend the soup
