This meat-free cottage pie is rich, savoury and properly satisfying. Mushrooms and green lentils create a substantial filling, while Roasty Roots Seasoning adds the familiar herby flavour of a classic roast dinner.

The seasoning also goes into the mash, so the golden topping tastes every bit as good as the filling underneath.

🧾 Ingredients

• 800g floury potatoes, peeled and chopped
• 30g butter
• 75ml milk
• 1 onion, finely chopped
• 2 carrots, diced
• 400g chestnut mushrooms, chopped

🍴 Instructions

1. Heat the oven to 190°C fan / 210°C conventional.
