In a large pot or Dutch oven, heat the olive oil over medium heat. Add the diced carrots and chopped scallions. Sauté for about 3-4 minutes until the vegetables are tender and fragrant.
Stir in the minced garlic and cook for an additional minute, stirring frequently to prevent burning.
Add the vegetable broth to the pot, bringing the mixture to a gentle boil.
Once boiling, add the orzo pasta and reduce the heat to a simmer. Cook for about 8-10 minutes, or until the orzo is al dente.
Stir in the baby spinach and let it wilt for 1-2 minutes. Season the soup with sea salt and black pepper to taste.
Ladle the soup into bowls and enjoy warm. This Quick Orzo Soup is perfect on its own or paired with crusty bread for a complete meal.
