This is Welsh comfort food at its best - layers of sliced potatoes and soft onions cooked together until sticky and golden.

Ingredients

  • 1/2 c
    unsalted butter, melted and warm
  • 1 lb
    onion, either sliced or finely chopped
  • 1
    rosemary sprig
  • 2 lb
    potatoes, thinly sliced (desiree or maris piper recommended)
  • 2 tsp
    fresh thyme, optional
  • ·
    salt and pepper
  • 4 oz
    caerphilly cheese, optional

How to Make Welsh Onion Cake

Step-by-Step

  1. Heat about 1/4 of the butter in a large pan, set over medium heat.
  2. Sweat the onions with a little salt and the rosemary sprig. Slowly cook on a gentle heat with a lid on for about 20 minutes. Remove rosemary and set aside.
  3. Grease an oven proof dish and on the bottom of the dish, place a thick layer of potatoes, well seasoned with salt and pepper.
  4. Add a layer of onions.
  5. Dot each layer with butter and thyme (if using), and repeat this again, or until the dish is full, ending with a layer of potatoes.
  6. The top layer should also be dotted with butter, using more than given above, if necessary. Cover with a lid or foil and bake in a moderate oven (350F.) for about one and a half hours, removing the lid for the last half hour.
  7. Note:
    The variety of potato makes it difficult to give a precise cooking time: very floury ones can cook in 1 hour where as waxy ones will take longer.

    If using the cheese, sprinkle a little bit on each layer.
