Käse Spaetzle with Caramelized Onions (The Ultimate Mac & Cheese)

When it comes to quick and easy meals on a weeknight, cooking from scratch at home does not have to mean spending countless hours in the kitchen. Half an hour is usually all that is, (roughly) needed to put together a healthy, filling, and nutritious meal. Cheese spaetzle, or Kase Spaetzle as it’s known in Germany, Austria, and Switzerland, is a popular noodle dish often served in casserole form.

Ideal on a cool fall evening or after a day of skiing, it is essentially a homemade Mac & Cheese recipe!! You’ll get the best results if you use homemade spaetzle noodles, but store bought ones may be substituted if you wish. I make my spaetzle noodles from scratch the night before, and then simply assemble this cheese spaetzle recipe and pop it in the oven to bake!German kase spaetzle in a back steel pan on a wooden board

Caramelizing Onions

Käse spaetzle are served in many restaurants, pubs, and mountain chalets, as a quick and filling meal. Traditionally this spaetzle dish is served with caramelized onions and topped with Emmental Cheese, (though any cheese may be used) and breadcrumbs before being baked in the oven. If you have never caramelized onions before, doing so is very easy! You could even just used fried onions instead if you prefer a crispier texture! True caramelized onions are velvety soft, and deliciously sweet, making them the ideal addition to offset the sharpness of the cheese! The instructions here make roughly one cup of caramelized onion.

Julianne an onion in a few simple steps!

To caramelize your own onion, roughly Julianne the 4 onions into thick strips. Most people make the mistake and try to caramelize the onions over to high of a heat, causing the onion to stick to the bottom of the pot and creating a bitter flavor. To avoid this fill the pot with the Julianne onion, and cover the pot with a lid while cooking over medium heat.

Keeping the moisture from the cooking onions in the pot, prevents them from scorching and increases the internal temperature which is needed to caramelize the natural sugars present in the onion. Cook the onions like this for about 15 minutes, until they start to turn translucent. Stir the onions to make sure they are not sticking as they caramelize, and then put the cover back on and keep cooking for another half hour.

At this point you will notice that the onions have started to caramelize and turn a brownish color. Remove the lid and keep cooking the onions uncovered to remove excess liquid. Keep an eye on the pot for the last 15 minutes of cooking to prevent the caramelized onion from scorching! Cool the onions when finished, or use right away in the following kase spaetzle recipe.

Pan fry the homemade spaetzle noodles in some butter.

It’s best to make the spaetzle the day before , which makes the spaetzle easier to fry in a pan. Otherwise let the spaetzle cool a little and melt the butter in a pan. Add your spaetzle noodles to the pan and lightly fry them until the start to turn a light golden color. Note: This is an optional step, and the spaetzle noodles can simply be mixed and baked with the caramelized onions and cheese without frying first.

  1. 5 stars
    I just happened to have a block of Emmental in the fridge – my favorite after a trip to Switzerland this spring – so I caramelized an onion and tried my hand at your spaetzle. Can’t wait to put it all together tomorrow! A little applesauce and I’ll feel like I’m back on Pilatus, thank you!

    • Yum! I just finished the last of my Emmental with this recipe. It sure is a great way to reminisce about working in Langenthal! Take some pictures and tag me on social media!

  2. This kicks mac and cheese’s ass! I didn’t know you could buy packaged spatzle, I’ll have to take a look.
