Quorn Moussaka Recipe UK: Easy Veggie Bake

Quorn moussaka is a hearty, comforting British twist on the classic Greek dish, swapping lamb for Quorn mince to create a lighter yet still satisfying vegetarian bake. Layered with rich tomato sauce, tender aubergines, and a creamy cheese topping, it delivers all the flavour of the original with far less fat. This recipe is perfect for a family weeknight dinner or a crowd-pleasing vegetarian centrepiece, and it freezes brilliantly too.

Ingredients

  • 2 large aubergines (about 800 g / 1 lb 12 oz), sliced into 1 cm (½ inch) rounds
  • 2 tbsp olive oil, plus extra for brushing
  • 1 large onion, finely chopped
  • 2 garlic cloves, crushed
  • 500 g (1 lb 2 oz) Quorn mince (frozen or chilled)
  • 2 x 400 g (14 oz) cans chopped tomatoes
  • 2 tbsp tomato purée
  • 1 tsp dried oregano
  • 1 tsp dried basil
  • 1 vegetable stock cube, crumbled
  • 1 tsp sugar (optional, to balance acidity)
  • Salt and freshly ground black pepper, to taste
  • For the topping:
  • 500 ml (2 cups) milk (semi-skimmed or whole)
  • 50 g (3½ tbsp) butter
  • 50 g (â…“ cup) plain flour
  • 100 g (1 cup) mature Cheddar cheese, grated
  • 1 tsp Dijon mustard (optional)
  • Freshly grated nutmeg (optional)

Instructions

  1. Preheat the oven to 200°C (400°F). Line two baking trays with baking paper. Brush the aubergine slices lightly with olive oil on both sides and arrange them in a single layer on the trays. Roast for 15–20 minutes, turning once, until golden and softened. Set aside to cool slightly.
  2. While the aubergines roast, heat the 2 tbsp olive oil in a large frying pan or saucepan over medium heat. Add the onion and cook for 5–6 minutes until softened. Add the garlic and cook for a further minute.
  3. Add the Quorn mince to the pan. If using frozen, cook for 5–7 minutes until fully thawed and any excess liquid has evaporated. If using chilled, cook for 3–4 minutes.
  4. Stir in the chopped tomatoes, tomato purée, oregano, basil, crumbled stock cube, and sugar (if using). Bring to a gentle simmer, then reduce the heat and let it bubble away for 10–15 minutes until thickened. Season to taste with salt and pepper.
  5. Meanwhile, make the white sauce. Melt the butter in a medium saucepan over medium heat. Stir in the flour and cook for 1 minute, stirring constantly. Gradually whisk in the milk, a little at a time, until smooth. Continue to cook, stirring, for 5–7 minutes until the sauce thickens and coats the back of a spoon. Remove from the heat and stir in the grated Cheddar and mustard (if using). Season with salt, pepper, and a pinch of nutmeg.
  6. To assemble, spread a thin layer of the tomato mixture over the base of a 3-litre (3-quart) baking dish (approx. 25 x 30 cm). Layer half the aubergine slices over the top, then half the remaining tomato mixture. Repeat with the remaining aubergine and tomato mixture. Pour the cheese sauce evenly over the top, spreading to cover completely.
  7. Bake in the preheated oven for 25–30 minutes, until the topping is golden and bubbling. If the top browns too quickly, cover loosely with foil for the last 10 minutes.
  8. Let the moussaka rest for 5–10 minutes before serving – this helps it hold its shape when sliced.

Tips

  • Don’t skip roasting the aubergines: This removes excess moisture and adds a lovely caramelised flavour. Frying them in a pan works too, but roasting is easier and less oily.
  • Make the white sauce ahead: You can prepare the cheese sauce up to 2 days in advance and keep it covered in the fridge. Reheat gently before assembling.
  • Adjust the consistency: If the tomato sauce seems too thin, simmer it a little longer. If it’s too thick, add a splash of water or red wine.
  • Use a food processor for the topping: If you prefer a smoother topping, blitz the sauce with a stick blender before pouring over.

Serving Suggestions

Serve the moussaka with a crisp green salad and some crusty bread to mop up the sauce. It also pairs well with garlic bread or a simple Greek salad with feta, olives, and cucumber. For a more substantial meal, add some roasted potatoes or a side of green beans.

Variations

  • Traditional Greek style: Use lamb mince instead of Quorn for a classic version. Cook the lamb thoroughly until browned, and drain off excess fat.
  • Add vegetables: Sauté some sliced courgettes or mushrooms with the onion for extra texture and flavour.
  • Spice it up: Add a pinch of chilli flakes or a teaspoon of smoked paprika to the tomato sauce for a smoky kick.
  • Swap the cheese: Use a mixture of Cheddar and Parmesan, or try a vegetarian Greek cheese like kefalotyri if you can find it.
  • Vegan option: Use a dairy-free milk and butter substitute, and a vegan cheese alternative for the topping.

Storage and Reheating

Leftover moussaka will keep in the refrigerator for up to 3 days in an airtight container. To reheat, place individual portions in the microwave for 2–3 minutes, or reheat in the oven at 180°C (350°F) for 15–20 minutes until piping hot throughout. The moussaka also freezes well for up to 3 months – thaw overnight in the fridge before reheating. Always ensure the internal temperature reaches 74°C (165°F) when reheating leftovers.

Frequently Asked Questions

Do I need to cook Quorn mince before adding it to the sauce? Yes, Quorn mince should be cooked before eating. If using frozen, it needs to be fully thawed and cooked through, which takes about 5–7 minutes. Chilled Quorn mince only needs 3–4 minutes to heat through. This step also helps to remove excess moisture and allows the mince to absorb the flavours of the sauce.

Can I make this moussaka ahead of time? Absolutely. Assemble the moussaka completely, then cover and refrigerate for up to 24 hours before baking. You may need to add 10–15 minutes to the baking time if baking straight from the fridge. Alternatively, bake it fully, let it cool, and then reheat as described above.

Why is my moussaka watery? This is usually due to the aubergines not being roasted enough, or the tomato sauce being too thin. Make sure you roast the aubergines until they are well softened and slightly browned, and simmer the tomato sauce until it has thickened before layering. Also, let the moussaka rest for 5–10 minutes after baking – this allows the layers to set and makes it easier to serve.

Can I use a different type of mince? Yes, you can substitute the Quorn with soya mince, lentils, or a mix of mushrooms and walnuts for a vegan alternative. If using soya mince, rehydrate it according to the packet instructions before adding to the sauce. Adjust the seasoning accordingly.

How do I know when the moussaka is cooked? The moussaka is cooked when the topping is golden and bubbling, and the sauce is hot all the way through. If you have a food thermometer, the centre of the dish should read at least 74°C (165°F). Let it rest for a few minutes before serving to allow the layers to settle.

Can I freeze the moussaka? Yes, this dish freezes very well. Allow it to cool completely, then wrap tightly in foil or place in a freezer-safe container. It will keep for up to 3 months. To serve, thaw overnight in the refrigerator and reheat in the oven at 180°C (350°F) until piping hot.
