How to Make Quark in the Oven

It is not coincident that I am already publishing my third version on how to make Quark. It just shows our German obsession with it … and its importance in the German cuisine. There is so much one can do with Quark!

What is Quark?

If you haven’t seen my other blogposts and videos about quark, let me give you a quick introduction:

Quark is a sort of fresh cheese. It is milk, injected with “good” bacteria and curdled with the help of either rennet or citric acid. The process of curdling leads to the separation of the whey and the casein in the milk. The casein is the milk protein and what we call Quark. It has a creamy, soft consistency, much like Greek yogurt but denser. In fact, often people here use Greek yogurt in place of Quark but it doesn’t always work out since yogurt is not the same as Quark and also still has the whey in it.

Other ways to make Quark

My precious recipes on how to make Quark were Making Quark from Buttermilk and Making Quark from Whole Milk with Kefir. Both methods have their upsides and downsides. While Quark from buttermilk is a quick way to make it, the taste of buttermilk is still present and not always suitable for a recipe. Also, it is very difficult to find REAL buttermilk in the US. Often the product does not have living buttermilk cultures but instead has additives that prevent this recipe from working.

The Quark from Kefir is an easy way to make it but it takes time and some people struggled with it because the temperature in their house was too cold and the kefir wouldn’t thicken. It’s also rather expensive with buying the kefir or kefir cultures.

Making Quark with Regular Milk

I am making Quark for years, using a machine that keeps the milk at the necessary constant temperature for an extended time. Since the machine is not available outside the EU, I needed to come up with an idea of how to achieve this in a different way.

I looked at yogurt makers but their temperature setting is too high and most of the time not adjustable. So, using a yogurt maker is NOT an option. I also looked at my slow cooker – too hot! Then I stumbled upon the method of using an insulated tumbler, which would be working great, if only they had a larger capacity since I want to use them with 1/2 gallon of milk or more.
So, my last resort was the oven! But the lowest oven settings are still way to high and I decided to heat the oven by just switching on the light bulb. And that seemed to be the solution!

But I was skeptical and measured the temperature in the oven with an oven thermometer … and after one and a half hours or so, the temperature was above 100°F, which again is too warm. Switching the light off at the right temperature helped. Since the oven is well insulated, it kept the temperature for long and my Quark turned out just perfect!

The Process of Making Quark

There are basically 4 steps on making Quark:

1. Heat the milk to 28°C / 82°F

2. Inject the culture and add the coagulant.

4. Leave it at the right temperature of 22°-30°C / 72°-86°F for 16 hours.

5. Drain the Quark.

Easy, don’t you think? There is just ONE VERY IMPORTANT RULE:


Which Culture, Coagulant, and Milk to Use

The Culture

As for the culture, you will need a Mesophilic Culture (HERE at amazon). But here is also a little trick: If you make Quark a lot, keep some of the whey. You can use it to inject the next batch of Quark, since it contains the mesophilic culture. This way you can save money and don’t need to use a bought culture every time. However, you should add the bought cultures every now and then and also don’t use the whey method if if might have gone bad.

The Coagulant

You have the choice between using Rennet (HERE at amazon) and Citric Acid (HERE at amazon). If you use rennet, you will later have a sweet whey, that you can use for a lot of other things. Using citric acid will get you an acidity whey and the quark might also taste a little sourer. I personally prefer rennet and it is available as a vegetarian product (HERE at amazon).

The Milk

In my video, I am using whole milk but you can use milk with less fat like 2% or 1%. You can use this method also with buttermilk and in fact, if you want to have a vegan Quark, just use nutmilk like from almonds or cashew or use soy milk.

What to do With the Whey

So, after draining the quark, you will end up with a lot of whey and you might wonder what to do with it.
Whey is full of vitamins, minerals, and protein, too precious to discard!
I like to put some whey into my bath because it’s great for the skin. But taking a bath in Texas is only suitable on a cold winter day, so it’s not a year round option. Most of the time I am using whey for baking bread. I just substitute it for the water in the recipe and the bread turns out wonderful and even healthier. I highly recommend you try this!
In Germany you can buy whey drinks that are made with fruit juice, often from lemons or oranges with a little sugar or sweetener. Mixing you whey with a juice or adding it to a smoothie is a great idea, too.

But there is a lot more you can do with whey like making soap or using it in the garden … and there is a website that has a lot of great ideas, so I will just link it HERE.

What to Do With Quark

Oh, where should I start? You can bake a German Cheesecake with it, use it in a Strudel (Quarkstrudel aka Topfenstrudel), make desserts, make Quarkkuchen, use it as a bread spread either under some jam or a slice of cheese, mix it with garlic and herbs and use it as a dip or bread spread, make quark-oil dough for pizza or quiche or bake quark rolls … there are so many possibilities and I will definitely make more recipes that require quark in the future.
My favorite way to eat quark is with fresh strawberries, some chocolate shavings, and a little vanilla sugar!

oven with light bulb
cheese cloth
optional: oven thermometer


  • ½ gallon milk any good quality cow milk or nut milk / soy milk
  • ¼ tsp mesophile culture
  • 5 drops rennet deluted in a little water


  • Switch on the lamp in your oven to get the oven to a temperature between 22°-30°C / 72°-86°F.
  • Make sure all tools are very clean and sterile.
  • Pour the milk in a pot an carefully heat it to 28°C / 82°F – this will only take a few minutes since it is a rather cold temperature.
  • Add the culture and stir the milk until diluted.
  • Add the rennet and stir for a brief moment, then bring the milk to a standstill.
  • Cover the pot with a lid and put it into the oven. Close the oven door. Ideally, control the oven temperature with an oven thermometer and switch the lamp off and on if needed to adjust the temperature.
  • Leave in the oven for 16 hours, then take it out. The milk should have thickened.
  • Put a cheesecloth into a colander that is placed above a bowl.
  • Pour the content of the pot into the cheesecloth, letting the whey drain while the quark is in the cheesecloth. Let drain for about 5 hours and more. For better draining, check out the trick in the video.
  • Remove the quark from the cheesecloth and fill it into a container or jar. Keep in the fridge until you use it. If you worked edclean, it will be good for at least 5 days, often 7 days.

If you still feel like you’d rather have a Quark Machine …

Here is one that ships from Germany to the US. Use the “Frischkäse” setting for making quark. It will hold 1.2 l (= 1.2 quarts) milk.
You will need a power converter, too.

    Hi Barbara,
    I think I have asked you this question before, but I cant find the answer anymore.
    How much Whey do you use instead of mesophile culture when making quark?
    I do use a youghurt makers which holds the temp at 97F instead of 87F but it works well and makes delicious quark.
    Love your website!!!

    1. I think 2 tablespoons should be enough on half a gallon. I use fresh cultures most of the time because the whey doesn’t last long and goes bad before we finished the previous batch of quark. But when using whey, I usually just add like 2 tbsp.

      1. Hi Barbara and Happy Thanksgiving!
        This might be a silly question but how long does whey last and how can you tell if it has gone bad. Is a week too long?

        1. I think a week can work with a very cold fridge and if you work very, very clean. They are bacteria after all, so they can go bad if the wrong strain is growing. The best solution is to make Quark back to back from the whey so there is not more than a day between getting the whey and making a new batch of quark. Maybe I’m too cautious but better safe than sorry … and using the bought cultures is still the safest way.

  2. i heat up a gallon of milk in its container in a water bath to 37 Celsius. i then add the culture and wrap (only in winter) the gallon container in a couple of covers and let it ferment for 24 hrs. i have, in the past, rehested mildly, when i did not see precipitation (i never add acid or rennin)

  3. Have you thought of using a sous vide method of cooking for quark? It uses a water bath with the temperature maintained by an immersion sous vide machine such as the Anova brand (which we have). It works by circulating the water through a heating element that maintains the temperature you’ve set +/- 1 degree. If you put the milk mixture into glass canning jars (lids screwed on tightly) and placed them into a container large enough to submerge them in the water, the sous vide machine will keep the water the proper temperature for hours. It has many other uses as well. I think you’d like it as a cooking method.

    1. That might work but should one run a sous vide machine for so many hours? I’m not sure if they are made for that.

      1. I often run my immersion sous vide for 12-16 hours One recipe even called for a full 24 hours. Just make sure you have a cover for your water bath and check on it every once in a while to ensure the water level.

    If you have a sous vide immersion cooker, I would think you could put the quark in a couple of quart canning jars with lids, and set your desired temperature. I know they make yogurt using that method. I’m surprised there is no salt added, is that right?

    1. That is right: NO SALT! We use our Quark in desserts, cakes, or as a dessert with fruits/honey. Only if we make a herb quark, we add some salt but not before the quark is made and finished.
