Reader Recipes: Lesley’s Thick Onion Tart

Lesley sent me this Thick Onion Tart recipe recently…

Serves 4, make in a 20cm tin

100g flour 3p
Pinch salt
2 tsps mustard
40ml oil 4p
Up to 40ml water
40g cheese (Asda Smartprice Cheddar £4.82/kg) 20p

700g onions, chopped 32p (Asda Smartprice 49p/kg)
50g butter 24p
2 eggs 20p
110ml milk 6p
60g cheese 30p

Mix all the pastry ingredients together, adding the water bit by bit until you get a soft ball of dough.
Melt the butter in a frying pan, add the onions and sauté them slowly, uncovered, over a low heat for 30-45 minutes, until they have turned a deep brown. Stir them every now and then, particularly towards the end. Then let cool a little

Line your dish with the pastry.

Tip the remaining ingredients, except the cheese, into the onions (they can’t be too hot, or they will scramble the eggs) and stir well. Tip this mixture into the pastry case and top with the cheese. Bake in a moderate oven (180C) for 30 minutes.

This is lovely hot with salady things, or cooked veg, and also makes a very nice lunch, cold, the next day
Total £1.39, 35p per person

  1. Thank you to Lesley (and Jack) for sharing this. I’ve just cooked one up to ensure I use up all my onions before they go bad. I added a little bit of garlic and cut up a few mini hotdogs just so nothing would go to waste. The kitchen smells amazing! Thanks again. 🙂

  2. Well, I tried this as didnt believe I could make pastry without spending 20 minutes rubbing in fat and still have it turn ok. OH MY LORD !! That is the best tart I have ever eaten. Delicious. Simple. Filling. Thankyou !
