Preheat oven to 190°C. Use a sharp knife to cut each bacon rasher, crossways, into 1cm-thick slices.
Combine the potatoes, onions, bacon and half the blue cheese in a large bowl. Season with salt and pepper. Spoon into a rectangular or square 2.5L (10-cup capacity) ovenproof baking dish. Sprinkle over the thyme leaves.
Use a fork to whisk together cream and chicken stock in a jug, and pour over the potatoes. Sprinkle with remaining blue cheese. Cook, uncovered, in preheated oven for 1 hour 20 minutes or until golden brown. Serve immediately.
