Preheat the oven to 200°C / 180°C fan.
Heat the olive oil in a casserole dish (one that has a lid) over a high heat. Add the beef cubes and sear until the beef edges are brown and sealed.
Mix the Bay’s Kitchen Concentrated Beef Stock with the water. Add this, the coconut milk, potatoes and carrots to the dish and bring to a simmer.
Once simmering put the lid on, then place in the oven for 2 hours.
Remove from the oven and stir through the bok choy and Bay’s Kitchen Thai Massaman Sauce. Place the lid back on and leave for 5 minutes.
Give one final stir before serving. Garnish with the peanuts and slices of red chilli.
Serve with rice and naan or poppadoms.
