Fasting Potato Moussaka

Preparation

1. Preparing the Potatoes

Peel and rinse the potatoes. Slice into rounds about 4–5 mm thick — not too thin (they fall apart) nor too thick (they won’t cook evenly). Submerge the sliced potatoes in a bowl of cold water while you prepare everything else, to prevent browning.

Before assembling, rinse off the surface starch (the water turns cloudy) and pat dry with a clean kitchen towel or paper towels. Surface starch can make the moussaka overly sticky.

2. Caramelising the Onion — the Key Step

Dice the onion finely. In a deep frying pan, heat 80 ml of oil (reserve the rest for drizzling) over medium heat. Add the onion and fry for 12–15 minutes, stirring occasionally. The goal is for the onion to soften, turn translucent and then develop a lovely golden-brown colour without burning. This is the most important step — the caramelised onion is the “soul” of fasting moussaka and replaces the flavour of meat.

Towards the end of frying, reduce the heat, add the paprika and stir immediately (paprika burns in about 30 seconds — stir and remove from the heat). Add the dried rosemary, half the parsley, pepper and salt. Leave to cool.

3. Layering in the Baking Dish

Preheat the oven to 200°C. Grease the baking dish with oil. Layer as follows:

• First layer: potato rounds overlapping slightly
• Second layer: one third of the caramelised onion
• Third layer: potato
• Fourth layer: one third of the onion
• Fifth layer: potato
• Top layer: remaining onion spread evenly

Season each potato layer lightly with salt and pepper.

4. Liquid and Drizzle

Slowly pour the water or vegetable stock over the whole dish — the liquid should come halfway up the dish, not to the top (the potato should bake, not boil). Drizzle the remaining sunflower oil (about 20 ml) over the top and finish with a drizzle of olive oil for extra aroma.

5. Baking

Bake in the preheated oven at 200°C for 45–60 minutes. Cover with aluminium foil for the first 30 minutes so the potato steams and softens. Then remove the foil and bake for a further 15–20 minutes until a golden-brown crispy crust forms on top.

The potato is done when a knife or fork passes easily through the thickest part. The liquid should have almost fully evaporated, leaving a rich reduced juices between the layers.

6. Resting and Serving

Very important: do not serve immediately! Remove the dish from the oven and leave to rest 10–15 minutes — the layers stabilise and portions are much easier to cut. Scatter with the remaining fresh parsley.

Serve warm alongside pickled cabbage salad, grated carrot or beetroot salad. Traditionally accompanied by a thin slice of homemade bread.

Tips

Double oiling for a perfect golden crust: the trick is to drizzle oil over the dish before baking, and then switch on the top grill element (250°C) for the last 5 minutes to get an extra-crispy top. Watch through the oven glass to avoid burning.

Without water (traditional variant): in some regions of Serbia moussaka is made without any added liquid — only the caramelised onion and its juices are layered between the potato. The result is more compact and crispier but requires juicier potatoes and a longer initial baking time with foil.

Strict fast (no oil): for strict days, replace the oil by sweating the onion in a little water — the onion won’t get golden colour, but the moussaka is technically in the water category. You can also add crushed walnuts for a richer flavour without oil.
