As explained by My Recipes, dishes often need to be made in advance for holidays or the Sabbath. Kugels can be extremely convenient because they can be prepared a few days before the feast, frozen, and served without much fuss. The casseroles can contain many ingredients including cheese, spices, onion, and herbs. Potato kugels are especially much-loved and you can expect to find vegetables such as zucchini and broccoli.
Quora users have previously discussed what it’s like to prepare kugels for Passover. One user wrote, “There are many types of kugel, and some are not kosher Passover, and some might be with some changes. Potato kugel is a family [favorite] and we can eat it year round.” They added that the original noodle kugel is not suitable for Passover but you can tweak the recipe and use kosher noodles if you’d like to include it in a meal. Another commenter simplified it further and wrote, “Kugel just means ‘pudding’ – to say ‘kugel’ is something like saying ‘casserole’. A kugel can have almost anything in it.” What a versatile meal, huh?
