Preheat oven to 325 degrees. Heat the olive oil a dutch oven or oven safe pot. Add the diced onion. Season with salt & pepper to taste. Sauté for about 5-7 minutes, until the onions are translucent. Add the garlic cloves (whole cloves) and cook for another minute or two. Remove the onions/garlic & set aside.

Add the short ribs & sear on each side over high heat. You're not wanting to cook them through, just give them a nice sear on the outside.

Reduce the heat to medium-high. Add the onion mixture on top of the short ribs. Pour in the beef broth.

Bring to a boil. Turn off the heat to the stove.

Place the covered oven-safe pot into the oven. Cook at 325 for 2.5 hours.
