Lower calorie versions of white sauce?

[MonsteraCheeseplant]

I need to lighten up my lasagne and the white sauce is a significant culprit of boosting the calorie content. Any ideas?

Delia does one without butter. Thickened milk then really. I really don’t use much butter in mine anyway so it’s the pasta that is the most calorific. I sometimes layer thinly sliced sweet potatoes instead of the pasta to make it lower calorie.

Holy crap why didn't I think of that? I love potatoes so much and lasagne with potatoes instead of pasta almost sounds better! Thank you very much for that suggestion.

Quark mixed with an egg yolk, a pinch of mustard powder, salt and pepper and sometimes some mature cheddar is a good replacement!

You can use leek layers instead of pasta. Unroll and lay flat. It's not as nice as pasta though.

This recipe uses blended cauliflower and it’s really nice, plus bonus sneaky extra veg hodgepodgedays.co.uk/recipe/cauliflower-lasagne-sauce/

I don't think i've ever tasted Quark before, just googled it, does it taste sour?

I have tried leeks instead of pasta and it's nice, but it's not lasagne.

Blended cauliflower is very imaginative, is there anything that veg can't do? I imagine it'd be a bit grainy.

If you cook the cauli as per the recipe, once you blend it it goes smooth. It’s very good, I like it a lot.

I recently discovered Heston's cheese sauce, which is made with stock and wine (you could omit the wine) and the cheese is lightly coated in cornflour. It is a bit weird to make, but works well and is tasty.
