Cranberries and Pistachios: A Perfect Christmas Combination
You will probably notice a theme in this year’s Christmas recipe collection: I use pistachios and cranberries in everything! Unsurprisingly so, pistachios are my favourite nut. Not only extremely buttery and tasty, but pistachios also add to the aesthetics of dishes too with their bright green colour. Cranberries are, of course, a Christmas tradition, but they add that little bit of tart sweetness that is just great in this vegetarian roast.

Why Use Two Types of Mushroom in This Vegetarian Sunday Roast?
Another one of my favourite ingredients is dried porcini mushrooms (also known as ceps). The deep, nutty flavour of porcini is hard to beat, but in this roast, it’s also about the tiny bits of texture that rehydrated porcini provide.
Chestnut Mushrooms, on the other hand, are used for moisture. Whilst they are fried in the pan to dehydrate them a little bit, they give this Vegetarian Roast a lovely moist texture that makes it easier to cut without it crumbling.

Ingredients and Substitutes
- green lentils: we used fried lentils, that we cooked from scratch, but tinned drained green lentils will work in this vegetarian Sunday roast too.
- chestnut mushrooms: can be replaced with your basic closed-cup mushrooms.
- dried porcini mushrooms: an absolute must in this vegetarian roast recipe, both for the flavour and the texture.
- breadcrumbs: use fresh breadcrumbs made with stale bread, panko breadcrumbs or your regular shop-bought breadcrumbs. Note though, that dried breadcrumbs will absorb more moisture, so you may need some extra gravy with your Meat-free Christmas dinner.
- brown onion: can be replaced with red onion, white onion or a couple of small shallots.
- Cheddar cheese: choose sharp mature Cheddar.
- soy sauce: light or dark.
- dried cranberries.
- pistachio kernels: unsalted.
- dried thyme: or other herbs like rosemary, oregano or a mixture.
- butter: we used unsalted.

Method: How to Make Vegetarian Roast?
Cook green lentils following instructions on a packet. Once cooked, drain and leave to cool down.
In the meantime, pour hot water over dried porcini mushrooms, just enough to submerge and leave for 15-20 minutes for the mushrooms to rehydrate. Then chop them finely.
Heat a large non-stick frying pan over low heat. Melt the butter in the pan, then add the onions and sautee for 6-7 minutes until softened. Add the chopped chestnut and porcini mushrooms, a pinch of salt and cook for a further 7-8 minutes until the water has released and evaporated.
In the meantime, chop the cranberries and pistachios roughly. Coarsely grate cheddar cheese.
Preheat the oven to 200°C Fan.
Mash the cooled lentils into a rough paste (if you have a food processor, just blitz them for a few seconds). Add the cheddar, cranberries, pistachios, breadcrumbs, thyme, soy sauce, 2 tablespoon of water and onions & mushroom mixture to a large bowl and mix. It may look a little dry but that’s ok.

Line a small (1.5-2lbs) loaf tin with baking parchment (we highly recommend Bacofoil Baking Parchment)and grease lightly with vegetable oil.
Add the roast mixture to the tin, pressing down into the corners and smoothing out the surface.
Place the roast in the oven for 40-45 min. The top should have browned and the roast should be firm when pressed. Leave the roast to cool in the tin for 5 minutes.
Gently turn the roast out onto a chopping board, let it cool slightly and cut into thick slices.

I started making nut roasts for my vegan family members last year for Christmas and I must admit I’m impressed with the taste. I would love to try my hand at your version because it looks so inviting.

I really hope you try this version, maybe you can cook it for your vegetarian family members and friends? But to be honest, I think even meat -eaters will enjoy this recipe 🙂
