This creamy tortellini soup is a comforting dish featuring tender cheese tortellini, fresh broccoli, and carrots in a rich, cheesy broth. Starting with a buttery roux and infused with aromatic spices, it's a hearty and satisfying meal ready in just 30 minutes, perfect for a quick yet flavorful lunch or dinner.
Achieving a smooth roux is crucial for this soup; melt butter thoroughly, then gradually whisk in flour until a paste forms, cooking for 1-2 minutes to eliminate raw flour taste. When adding broth, pour slowly while whisking constantly to prevent lumps. For optimal vegetable texture, add harder vegetables like carrots earlier, followed by broccoli. The tortellini cooks quickly, so add it last to avoid overcooking and a mushy texture. Integrate the heavy cream and Colby cheese off the heat or over very low heat to prevent curdling, ensuring a silky, rich finish. Adjust salt and pepper at the end, as the chicken broth and cheese will add salinity. A final sprinkle of fresh herbs like parsley or chives can enhance presentation and add a fresh counterpoint.
