The nice thing about casserole is you could have it every day of the year and never have to repeat the same one twice. There are endless combinations of ingredients to try out, and while some of those combinations might seem a little unusual, it’s not uncommon to find one that surprises you with its deliciousness. Take this Polish Casserole, for example. While tucking sauerkraut into a casserole might seem a little strange, you’ll actually find that its tang actually goes perfectly with a creamy sour cream-based sauce, smoky kielbasa, and nutty Swiss.
To make this sauce, you’re starting with a roux and building a bechamel, but then dressing it up with some Dijon mustard and sour cream. These both bring in a bit of acidity to balance the richness, and they echo the tang in the sauerkraut. The sauerkraut isn’t too sour though – it gets rinsed off and drained before everything gets mixed together to keep it from overwhelming the dish.
Any short pasta will work fine here, but penne has a nice way of catching that delicious sauce. You can think of it like mac and cheese with a Polish twist, but thanks to the kielbasa, it’s plenty hearty. It’s a flavor combo that’s a little unique, but it’s a seriously yummy one.
