In a large Dutch oven or stock pot heat olive oil over medium-high heat. Once warm add in the diced onion, sauté for 2-3 minutes until onions start to soften. Add in minced garlic, salt, and pepper, sauté for another 1-2 minutes until fragrant.
Deglaze the pan with lemon juice, add in lemon zest and dry rice. Sauté the rice over medium-high heat for 2-3 minutes. Add in chicken stock and chicken breast. Cover and simmer for 15-20 minutes, or until rice and chicken are cooked. Stir often so the rice doesn't stick to the bottom of the pan.
Remove chicken breast, shred with two forks and return to the pot. Add in the heavy cream, stir to combine.
Serve immediately with warm bread, garnish with parmesan cheese and fresh herbs!
Notes
*This soup can be kept in an airtight container in the fridge, the soup may thicken once chilled. If that happens thin with a bit of water or chicken stock.
