Heat (an extra) 1 tablespoon butter or olive oil in a stockpot on medium-high heat. Add onion and sauté for 5 minutes, stirring occasionally, until soft. Stir in the garlic and cook for an additional 1-2 minutes, stirring occasionally. Add broccoli, mushrooms, chopped potatoes, and carrots. Stir for another 1-2 minutes.
Add in the chicken broth, water, almond milk, and salt. Stir to combine.
Continue cooking until the soup reaches a simmer. Then reduce heat to medium-low, cover and simmer for 30 to 40 minutes until the rice is tender, stirring occasionally.
Serve warm and enjoy!
