Creamy chicken tortellini soup is a one-pot weeknight soup: tender chicken, cheese-filled tortellini and spinach in a rich double-cream broth. It cooks in a single pot on the stovetop, with slow cooker and Instant Pot methods below, and it is ready in 45 minutes from scratch, or about 30 minutes when you start with cooked chicken.
The method is built around two rules that keep the soup at its best: the tortellini goes in last, so it stays tender instead of turning mushy, and the cream goes in over a gentle simmer, never a hard boil, so it stays smooth. Spinach wilts in at the very end, and a handful of Parmesan finishes the broth.
In the UK, this is a straightforward supermarket shop: chilled tortelloni from the fresh pasta aisle, double cream for the broth, and a supermarket roast chicken if you want the shortcut version.
