This warming Beetrook Bake with Parmesan recipe is from The Great Dixter Cookbook: Recipes from an English Garden by Aaron Bertelsen, published by Phaidon.
A seasonal take on the classic fish pie but using celeriac as a lovely alternative to mashed potato.
The lightly smoked salmon comes alive with the addition of lemon zest and thyme, whilst the rosemary and garlic combine with the fresh chilli, sweet potato and carrots to deliver a warming, comforting healthy mash, and the truffle oil adds depth of flavour.
