Step-by-Step Guide to Making Slow Cooker Creamy Tomato Basil Tortellini Soup

Heat olive oil in a large skillet over medium-high heat. Add carrots and onion, sauté for 3-4 minutes until softened, and then stir in garlic, sautéing for another minute until fragrant.
Transfer this vegetable mixture to a 6 or 7 quart slow cooker. Add in the whole Roma tomatoes, vegetable broth, chopped basil, bay leaves, and sugar. Stir well to combine and season with salt and pepper to taste.
Cover the slow cooker and set it to cook on LOW for 6-7 hours or HIGH for 3-3.5 hours.
Once cooking is complete, remove the bay leaves. Puree the soup in small batches in a blender or use an immersion blender for a creamy texture.
Stir in the tortellini, cover the slow cooker, and continue cooking on HIGH for an additional 15-20 minutes until the tortellini is heated through.
Reduce the heat to warm and gently stir in the heavy cream. Adjust the consistency if needed by adding 1/2 cup of water if the soup is too thick.
