December 26, 2013 6:32 PM

What to do with all the Christmas leftovers – for many, it’s a big question every year. So why not ask the expert. We tapped Big Night Entertainment Group’s Executive Chef, Kevin Long for a creative recipe that can turn the Christmas roast beef into a delicious leftover.

He was kind enough to give us: “Butch’s Roast Beef Hash.”

Butch’s Roast Beef Hash

(Butch has been my dad’s nickname since he was a boy. This is one of his favorite dishes – I think he likes it more than the roast beef the night before)

2 lbs. leftover roast beef – the more ends, crunchy & fatty bits, the better
2 cups chopped onions, lightly sweated
2 cups chopped potatoes, lightly sweated
2 pinch of onion powder
2 pinch Bell’s seasoning
Salt & Pepper
1/2 stick of butter

To make the Hash:
Melt the butter on medium heat, cut beef into 1/2 inch cubes and add to butter. Wilt down 5-10 minutes until it comes together like a hash consistency. Add the onions, potatoes and seasonings. Continue to cook another 5-10 minutes until the onions caramelize and melt in. Scrape up and bits that stick to the pan (that’s the best part). Add a few drips of water or beef broth to moisten if needed.

Serve with poached eggs on top.

Old school restaurant secret: Make sure you poach your eggs in water just below a boil with a few drops of white vinegar in the water.
