By OcadoLife
Published on 18 July 2025
Full of fresh, zingy flavours, this Seared Tuna with Marmalade-Dressed Fennel Salad was created by chef Milli Taylor – head of Ottolenghi Test Kitchen and the author of food and travel Substack When in Rome. Sear the tuna hard and fast so it's golden on the outside and gorgeously pink in the middle. Delicious as part of a sharing spread – serve it alongside Millie’s Lamb and Aubergine Loaded Houmous (search for the recipe online).
