In a casserole dish add a dash of olive oil, add the mushrooms and venison. On the hob brown the venison, add the bacon and the garlic.
Then add the beef bone broth, red wine, shallots and rosemary and stir.
Put the lid on the casserole dish and place in the oven for 90 mins.
Make a paste with the cornflour and gently stir a little at a time into the mixture around 20 mins before the cooking time is up. Once 90 minutes is up it is ready to serve.
