Caputo’s Caramelized Onion Meatballs

Caputo’s Caramelized Onion Meatballs
5 T butter
1 large onion, diced
1 clove garlic, minced
2 lbs. lean ground beef
1 ½ lbs. ground pork
2 egg yolks
salt and freshly ground pepper to taste

Melt ½ the butter in a pan, add the onion and cook over medium-low heat, stirring occasionally, for about 10 to 15 minutes, or until well browned. Combine ½ of the onion with the remaining ingredients and mix well in a bowl. Reserve the remaining ½ of the onions. Shape the mixture into meatballs.

Melt the remaining butter in the pan, add the meatballs and cook over medium-high heat until browned and cooked through. Add the remaining ½ of the onions just to heat. Transfer the meatballs to a dish and spoon over the onions and cooking juices.
