Sheet Pan: Flanken Beef Ribs (Costillas de Carne)

Flanken beef ribs make the perfect Sheet Pan meal. Why do we love a good Sheet Pan Recipe? They are the perfect answer to a busy weekday. You can throw everything onto the sheet pan, pop into the oven and move on. Everything cooks while you are tending to all the other things that await your attention.

Flanken Beef Ribs are the best kept secret in the meat department. Flanken, Beef Short Ribs and Beef Spare Ribs are all actually the same piece of meat. The difference is simply in how it is cut. It is one of the most flavorful cuts and they also happen to be one of the cheapest at $7 per pound. Easy and Cheap? How can you go wrong?

Things to know making this Flanken Beef Rib Sheet Pan Recipe

The ribs are rubbed with spices and herbs before roasting alongside potatoes and shallots. You can swap the potatoes for another hearty vegetable. Think sweet potatoes, brussel sprouts or carrots. You want to pick something that is strong enough to stand up to the long cook time.

Everything must be cut in uniform! The great part about the sheet pan meal is that everything can cook at the same time. The Flanken Beef Ribs take about an hour, which is why we only halve the potatoes and keep the shallots whole. If the vegetables are cut too small they will over cook.  They ribs are cooked on the bone and have fat marbled throughout the meat allowing them to hold up to a long cooking time.

They would be delicious served with our Olive Salsa Verde or our Chimichurri
