Chop up 3 rasher Bacon and add it to a frying pan with 1 teaspoon Olive oil. Gently cook for 4-5 minutes until the bacon starts to crisp.
Add 3 Shallots, 80 g Button mushrooms and 2 Garlic clove to the frying pan and cook for 2 minutes more.
Add 500 g Green beans to the slow cooker.
Add the bacon mix on top.
Pour in 350 ml Chicken stock and cook on high for 3 hours.
Notes
How long you cook the bacon for really is a preference thing. Some people like their bacon really crispy, in which case cook it for a couple of minutes longer.
The bacon softens a little when cooking, so you can save some of the crispy bacon to sprinkle on top before serving.
Try to make sure all the green beans are pointing the same direction in the slow cooker, rather than overlapping diagonally. This will help them cook evenly.
You can make this a more filling side dish by adding diced potatoes and cooking them all together. They might need cooking a little longer, but the beans will be fine with longer in the slow cooker.
Always use fresh green beans, not canned.
You can make this a vegan side dish by leaving out the bacon and using vegetable stock.
Add some extra flavour to the finished dish with a sprinkle of red chilli flakes.
