Cooking Instructions

The protein cooking time listed in this recipe has been updated.

As of December 2025, we’ve revised cooking times for all our proteins to reflect improved food safety guidance.

Check out the latest recommended times in our Cooking Guidelines.

  1. Preheat the oven to 220C / fan 200C / gas mark 8. Bring a large saucepan filled with salted hot water to a boil. Add the lentils and boil for 20-25 mins, until cooked, then drain.
  2. Thinly slice the sweet potatoes into 1/2cm discs. Place onto a large lined baking tray and toss with 1 tbsp oil, a pinch of sea salt and black pepper. Spread into a single layer. Roast for 15-20 mins, until soft and golden.
  3. Finely chop or crush the garlic. Finely dice the carrots (peel optional) and onions. Heat a large saucepan with 1 tbsp oil on medium-high heat. Add the garlic, carrots and onions and cook for 5 mins, until softened. Add the venison and Italian herbs, then cook for 5-7 mins, breaking up the mince with a spoon, until golden brown.
  4. Add the passata, 350ml hot water and crumble in the stock cube. Bring to a boil, then simmer for 10-15 mins, stirring occasionally, until thickened. In the final 1-2 mins, rinse the spinach and add to the pan along with the cooked lentils. Stir to combine, then season with sea salt and black pepper to taste.
  5. Make the bechamel; mix the cornflour in a jug with 2 tbsp cold water. Return the empty lentil saucepan to high heat. Add the yeast and cream, bring to a boil, then lower the heat to a simmer and gradually stir in the cornflour mixture. Stir frequently for 1 min, until thickened. Season with sea salt and black pepper to taste.
  6. Spoon half the venison mixture into a medium ovenproof dish. Top with half the sweet potato discs. Spoon the remaining venison on top, then cover with the remaining sweet potatoes. Spread the bechamel on the top. Bake for 10-15 mins, until golden and bubbling, then serve at the table.
