Sauté the onions and garlic in a large pot over medium heat until translucent, about 5 minutes.

Add the artichokes, vegetable broth, and seasonings. Bring to a gentle simmer, allowing flavors to meld for about 10 minutes.

Blend the mixture until silky smooth using an immersion blender or in batches with a countertop blender.

Stir in the heavy cream and lemon juice, heating gently until warmed through.

Serve in bowls garnished with fresh herbs or croutons.
