Smørrebrød with Beef Patty, Caramelised Onions and Mustard Cream
Beef Patty with Caramelised Onions and Mustard Cream © kvalifood.com
Beef patty with soft onions is classic Danish everyday food, here served as smørrebrød. The caramelised onions are the key — they need to be cooked slowly for 25–30 minutes until completely soft, deeply golden and almost jam-like in their sweetness. It is a technique that takes patience but rewards with a depth no quick frying can match. The patty itself is mixed with egg and breadcrumbs to hold in the juices and is cooked medium, so it is pink inside. The mustard cream with two kinds of mustard gives the sharp contrast that the sweet onion and salty meat need. It is a filling, down-to-earth smørrebrød without fuss.
