Straßburger Auflauf is one of those dishes I always come back to when I want something warm, creamy and filling on the table without too much fuss. The classic German pasta bake with sausages, melted cheese and a rich egg custard has everything a proper weeknight dinner needs – and it actually turns out even better in the air fryer. A crispy top, a soft centre, and ready in just under 25 minutes. Here you get my tested method, so you hit the right balance between creaminess and crispiness the very first time.

Why I love Straßburger Auflauf in the air fryer
A good Auflauf needs two things in balance: a creamy egg custard that has only just set, and a golden, crispy surface with bubbles of melted cheese. In an ordinary oven it typically takes 35-40 minutes – in the air fryer I have consistently nailed it at around 22-25 minutes. The heat circulates much closer to the dish, so the cheese browns quickly and evenly without the base drying out. For me it also means I can make a quick weeknight version for the family without having to fire up the big oven first.
The difference between air fryer and oven
The air fryer is essentially a small convection oven, and that is exactly what benefits a dish like Straßburger Auflauf. Where an ordinary oven takes a long time to come up to temperature, the air fryer is ready in 2-3 minutes. The result is less time to the table and a cheese surface that becomes more intense in flavour, because the heat is distributed close to the dish. I also find that the pasta holds on to its moisture better, because the total cooking time is shorter than in the oven.
My kitchen test of Straßburger Auflauf
I have made this dish three times in my Philips XXL and twice in a smaller Cosori model before I settled on a method that works every time. 180°C for 22-25 minutes hits the mark in a medium-sized dish of around 20 cm. I always preheat for 3 minutes – it makes a clear difference to the cheese surface. And then there is the most important detail: the egg mixture must be poured over just before the dish goes into the air fryer. If it sits and soaks into the pasta, the base gets too wet and the top loses its crispiness.
The first time I went with 200°C for 18 minutes, and the cheese turned almost black at the edges while the middle was still runny. 180°C is the sweet spot for this kind of egg custard. In a large air fryer with a rack insert I use a long ceramic dish, while in a smaller model I go with a round foil tray of around 18 cm. Either way, the dish must never be more than two-thirds full, so there is still room for the cheese to bubble up.
Never pour on the egg mixture before the dish is ready next to the air fryer. Every minute it is allowed to soak down into the pasta costs you crispiness on top.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
I have made the mistakes myself, so you do not have to. The first and by far the most common mistake is using uncooked pasta – it does not work in the air fryer, because there simply is not enough liquid for the pasta to turn tender in 22 minutes. Always cook it al dente first, about 2 minutes less than the packet states, so it does not turn mushy when it finishes in the air fryer. The next classic is forgetting to grease the dish – a lightly greased dish lets the portions come away cleanly, so you do not have to scrape the cheese crust off the bottom. The third mistake is about the sausages: if they are sliced too thinly, they turn dry and chewy. I cut my Vienna or frankfurter sausages into slices of around 1 cm, so they keep their juiciness throughout the whole baking time.
How to serve Straßburger Auflauf
I like to serve the dish simply, with something fresh on the side to balance the creamy richness.
- A crisp green salad with vinaigrette and a little red onion
- Pickled beetroot or cornichons that cut through the cheese
- Coarse bread or toasted rye bread to mop up the sauce
- A glass of cold lager or a light Riesling, if you want to keep the German theme
Storage and reheating
Leftovers keep nicely for 2-3 days in the fridge in an airtight container. I reheat them in the air fryer at 160°C for 6-8 minutes – it is far better than the microwave, which makes the cheese chewy and the pasta rubbery. If the dish is cold all the way through, you can cover it loosely with baking paper for the first couple of minutes, so the top does not burn while the middle heats up.
FAQ
I use classic macaroni or penne, as they hold their shape well during baking. Always cook them al dente first, 2 minutes less than the packet states, so they do not turn mushy in the air fryer.
Yes, bratwurst or bockwurst work really well too and give a more robust flavour. Avoid very thin grilling sausages – they turn dry over the 22-25 minutes at 180°C.
A dish of around 18-20 cm fits most air fryers and has room for 3-4 portions. Always check that there is at least 2-3 cm of space above the dish, so the heat can circulate around the cheese surface.
For me, Straßburger Auflauf is the epitome of the kind of food where a little work gives a lot of flavour back. Try it on a Tuesday when time is tight – you will come back for it.

Ingredients
Meat filling
- 400 g minced meat (Mixed pork and beef)
- 1 pcs onion (Finely chopped)
- 2 clove garlic (Finely chopped)
- 250 g mushrooms (Fresh, sliced)
- 2 tbsp tomato purée
- 1 tbsp olive oil
- 1 tsp paprika (Sweet)
- 1 tsp dried thyme
- 1 tsp salt
- 0.5 tsp pepper (Freshly ground)
Pasta and topping
- 250 g pasta
- 200 g crème fraîche (18 %)
- 100 ml whipping cream
- 150 g grated cheese (any melting cheese)
How to make it
Preparation
- Cook the 250 g pasta in plenty of salted water for 2 minutes less than stated on the packet, so it is al dente. Drain and rinse briefly under cold water.
- Finely chop the 1 pcs onion and 2 clove garlic. Slice the 250 g mushrooms.
Preparing the meat filling
- Heat the 1 tbsp olive oil in a frying pan over medium heat. Sauté the onion and garlic for 2-3 minutes, until they soften.
- Add the 400 g minced meat and brown it, stirring, for 5-6 minutes, until it is crumbly and cooked through.
- Add the mushrooms and continue frying for 4-5 minutes, until the liquid has cooked away.
- Stir in the 2 tbsp tomato purée and fry for 1 minute. Season with 1 tsp paprika, 1 tsp dried thyme, 1 tsp salt and 0.5 tsp pepper. Take the pan off the heat.
Assembling and cooking in the air fryer
- Gently fold the cooked ribbon noodles together with the meat filling in a large bowl.
- Whisk the 200 g crème fraîche and 100 ml whipping cream together in a bowl. Season with a little extra salt and pepper if you like.
- Spoon the noodle and meat mixture into an ovenproof dish that fits in your air fryer. Pour the cream mixture evenly over the top and sprinkle the 150 g grated cheese (any melting cheese) on top.
- Place the dish in the air fryer and bake the Auflauf for 15-18 minutes, until the cheese is golden brown and bubbling gently. (Check a couple of times along the way.)
- Let the Auflauf rest for 3-4 minutes so the sauce thickens before you serve.
Our notes for the recipe
Use an ovenproof dish that fits snugly in the air fryer basket – that way the hot air can circulate around the dish and give you the perfect cheese crust. Variation:
Add 100 g diced bacon along with the minced meat for an even richer flavour, or stir 150 g frozen peas into the filling for a touch of freshness. Parmesan blended into the cream adds extra umami. Serving:
Serve the Auflauf with a crisp green salad and a tangy vinaigrette – it balances the creamy, hearty gratin perfectly. Portion size:
If your air fryer is smaller, you can make the dish in two batches or use two small dishes for the best result.
