This dish kept me up last night because once the idea struck me, I couldn't stop thinking about it. A crispy hash brown cake topped with shaved prime rib, a poached egg, and a tangy Bearnaise sauce.   
No kidding, I thought about it going to sleep and several times when I woke up during the night.  I thought of little details, like using the leftover egg whites from the Bearnaise sauce as a binder for the hash brown cakes.  By the time I got up this morning, I had the idea all worked out.
This is by no means a tutorial on how to make a Bearnaise sauce.  There's a little bit of an art to that, knowing how to avoid splitting the sauce (over heating, too much oil) or over cooking the eggs.  If you have never made a Hollandaise or Bearnaise sauce before, I'd recommend googling a video or two on how to make one, first.      
Prime Rib Eggs Benedict
by 
Ingredients
- 8 oz prime rib, finely shaved (or any thinly sliced roast beef)
 - 6 eggs
 
- 20 oz refrigerated hash browns
 - 1/4 cup onion, finely chopped
 - 1/4 cup bell pepper, finely chopped
 - 4 egg whites
 - 1/2 tsp kosher salt
 - 1/4 tsp black pepper
 
- 1/4 cup dry white wine
 - 3 Tbsp white wine vinegar
 - 3 sprigs fresh tarragon
 - 1 small shallot, diced
 - 8 black peppercorns, crushed
 - 4 egg yolks
 - 1 tsp cold water
 - 1/2 cup clarified butter (melted but cooled slightly)
 
Instructions
- Make the hash brown cakes. Mix all ingredients together. Form into six cakes 1 inch thick and 4 inches in diameter. Place on a greased cookie sheet and bake at 400f for 45 minutes or until crispy and cooked through.
 - Make the Bearnaise sauce. Place the wine, vinegar, stems from the tarragon (leaves removed and reserved), shallot, and pepper in a small sauce pan. Cook over med-high heat until reduced by 2/3rds. Strain the liquid (gastride) and set aside, discard the solids.
 - Bearnaise sauce (continued) In a double broiler over medium to medium low heat, rapidly whisk the egg yolks and water until frothy and doubled in volume (about 5 minutes). Add the clarified butter in small batches, whisking continuously. Add the liquid (gastride) and chopped tarragon leaves. Whisk until thickened to point of coating a spoon. Keep warm in a thermos.
 - Poach the eggs. In a large pan with 1 1/2" of almost boiling water (190-200f) and 1 Tbsp of vinegar, ease each egg into the water. Cook for 4 minutes. Use a slotted spoon to remove.
 - Assemble the Benedict. Top each cake with some of the beef, an egg, and the Bearnaise sauce.

| Using a 4 inch ring mold makes forming the cakes easy and you can pack them tightly. |

| The gastride will be insanely fragrant, but don't worry, it won't overpower the sauce. |

| I use a mixing bowl over a 3 quart pan to make a double broiler. |

| Shave the beef as thinly as you can. It doesn't have to be whole slices. | 
They were delicious, better than a normal Eggs Benedict but then again, it's not every day that I have leftover prime rib in the fridge either.  Next time I'd be tempted to pan fry the hash browns instead for time purposes.
