Step 1: Sauté the Aromatics
Heat olive oil and butter in a large pot over medium heat. Add chopped onion and cook for 5- 6 minutes until soft and translucent.
Step 2: Add the Garlic
Add whole garlic cloves. Stir gently and cook for 3–4 minutes. The garlic should soften without browning.
Step 3: Build the Soup Base
Pour in broth and water. Add bay leaf, salt, and pepper. Bring to a gentle boil, then reduce the heat.
Step 4: Simmer Slowly
Cover and simmer for 25 - 30 minutes, until the garlic becomes very tender.
Step 5: Blend (Optional)
Remove the bay leaf. Blend with an immersion blender until smooth, or leave slightly chunky if preferred.
Step 6: Adjust Seasoning
Taste and adjust salt and pepper. Garnish with fresh herbs if desired. Serve warm.
