Before you begin, this recipe takes around 5-10 min to prep, so get your casserole dish and all your ingredients ready, then wash your fruit and veg.

Preheat the oven to 220°C/ 200°C (fan)/ gas 7 and boil a kettle.

Heat a hob-safe oven-proof casserole dish with a drizzle of vegetable oil over a medium-high heat. Once hot, add your Fable pulled mushrooms to the dish and cook for 1-2 min or until the mushrooms are lightly browned, breaking them up with a wooden spoon as you go.

Cut your potatoes in half. Add the halved potatoes to a heatproof bowl and cover with cling film, then pierce a few holes in the top with a fork. Put the bowl in the microwave for 4 min or until slightly softened. Add the softened potatoes to a baking tray (or two!) with a drizzle of vegetable oil and put the tray[s] in the oven for 25-30 min or until golden and crisp.

Meanwhile, peel and finely slice (don't chop!) your garlic. Top, tail and chop your carrot[s] roughly (no need to peel!).

Once the Fable pulled mushrooms are browned, add the sliced garlic and chopped carrot to the pot with 1 tbsp [½ tbsp] [2 tbsp] flour and your tomato paste and cook for 1 min or until fragrant.

Once fragrant, add your stout paste, Marmite, gravy base and bay leaf[ves] to the pot with 350ml [460ml] [600ml] boiled water and bring to the boil over a high heat. Cover with the lid and put the dish in the oven for 25-30 min or until the sauce has thickened.

Once the casserole has had about 15 min, trim your green beans and add to a large piece of tin foil (or two!) with a splash of cold water, a pinch of pepper and a knob of butter and scrunch the foil around the green beans to form a tightly sealed parcel[s].

Firmly crush the potatoes with a spatula, add a knob of butter and a pinch of pepper and mix it all together, then return the tray[s] to the oven and cook for a final 10-12 min or until the green beans are tender and the potatoes are golden and tender.

Serve the oven baked Fable mushroom & stout casserole with the green beans and crushed buttery potatoes to the side. Season to taste.
