Lasagne with lots of cheese sauce is one of my favourite foods and always has been. However, it can be full of cheese and very unhealthy! The way I make it now as a low-fat cheese sauce with quark I enjoy it whilst it is also healthy.

Why choose my low-fat cheese sauce with quark?

Whilst it isn’t the same as a full-fat cheese sauce I do not feel like I am missing out when I have this. I thought I would share this cheese sauce recipe with you to try too.

The recipe is low in fat but works perfectly and will, I promise, soon be a family favourite!

Quark tips for cheese sauce

In recipes that need quark, there are a few simple things you can do to ensure it tastes good. Quark doesn’t have much flavour so ensure you flavour the dish well.

Quark is available in most large supermarkets now and even stocked in Aldi and Lidl. You can usually find it near soft cheeses in a tub similar to that you would buy cottage cheese in.

Due to the low-fat content of quark, it easily splits if heated too much or has hot water or hot liquid added to it.

Be careful and stir in gradually and you should be ok. This is something to really remember when making this low-fat cheese sauce with quark.

What is Quark?

It is a soft cheese made with skimmed milk. It’s rather like Philadelphia in its consistency and, due to the fat-free aspect of it, there is little flavour. Because of this, quark on its own is not often enjoyed.

Quark is, due to its limited flavour, very versatile and useful in some great recipes. I frequently use it in both sweet and savoury recipes and share a variety of my favourite quark recipes.

The importance of adding vegetables to your meals

Vegetables are low in calories compared to their density. This essentially means that they fill you up with very few calories.

The more vegetables you have in a meal either as a side dish or mixed in with the meal itself the lower-calorie the meal tends to be. A filling but low-calorie meal is perfect for weight loss.

All my recipes include vegetables where possible but do feel free to add more as an accompaniment when you can.

Always choose vegetables that you enjoy because otherwise you will begrudge eating them and are more likely to before long stop cooking them at all.

Trying vegetables cooked differently or with herbs and spices can make them a little more exciting too.
