Peel and dice the potatoes. Rinse them with cold water.
2 cups potatoes
Add the potatoes, stock, and bay leaf to a medium saucepan. Add a pinch of salt if your stock is unsalted. The potatoes need to be just covered in stock. Bring everything to a boil but don't add a lid to the saucepan. The potatoes thicken up nicely as the liquid evaporates during the slow simmer.
1 cup beef stock, 1 bay leaf
Reduce the heat to a gentle simmer and let the potatoes stew for 15-20 minutes in the stock until fork tender. Stir them every 5 minutes.
Remove the saucepan from the heat and take out the bay leaf. Drain any excess stock.
Add the butter and cream to the potatoes and stir gently. Season the stewed potatoes with salt and pepper to taste.
1/4 cup heavy cream, 2 tbsp butter, 1/2 tsp salt, 1/8 tsp pepper
Garnish with fresh parsley and serve immediately as they thicken quickly.
1 tbsp fresh parsley
Notes
Storage: Leftover stewed potatoes can be stored in an airtight container in the fridge for up to 3 days. Reheat them on the stove or in the microwave with some extra stock or milk to loosen them up.
