Senfeier, also known as eier in senfsoße, is a classic German comfort food that consists of boiled eggs smothered in a smooth, and creamy mustard sauce. Typical accompaniments to this vegetarian specialty include boiled or mashed potatoes, rice, wilted spinach, blanched kale, and various vegetables such as carrots, broccoli, cauliflowers, or peas.

Fried onions and bacon bits can be added for extra flavor, and the dish can be garnished with freshly chopped parsley or dill on top, if desired. This simple dish is often prepared around Easter because it provides an easy way to use leftover Easter eggs.
