"Käsespätzle is a popular dish in Germany and people like to recreate it in the US because it is so simple and tastes so good. Cheese Noodle Casserole is foolproof if you take the time to make it right. Homemade Spätzle are the best for this dish, although you can substitute dried noodles from the store, if necessary. Caramelizing the onions takes about 1 hour, noodles - 30 minutes and casserole bakes about 35 minutes. Serves 2 - 4, depending on hunger and side dishes served. See larger image..."
