Central Market has Kobe roast beef that they make in-house. It is insanely good and every time I'm at the deli counter I am trying to think of ways to eat it. Truth be told, I stole this sandwich idea from Central Market. They have a roast beef sandwich in their prepared foods section with brie on it and it is so good that I thought I would try to recreate it at home. I thought I would up the ante a bit and add caramelized onions and serve it warm. Delicious!
Roast Beef Sandwich with Caramelized Onions and Brie
1 lb. roast beef
2 loaves of Italian white bread or ciabatta bread
1/2 lb. brie (a triple cream tastes best)
caramelized onions (recipe below)
Split the bread in half horizontally. First layer brie, then put the roast beef on top. Next, put a layer of caramelized onions and then another layer of brie. (The brie "layer" really ended up being little chunks. The triple cream is hard to slice.) Put the bread lid back on the sandwich and wrap the whole loaf in foil. Repeat with the second loaf of bread. The foil keeps the bread from getting crispy; don't skip this step or you'll be sorry. Place the loaves in an oven preheated to 350°. and warm for 15-20min, or until the brie is melted. Slice and serve. (Makes enough for about 5 or 6 sandwiches.)
(from Barefoot Contessa Back to Basics)
2 T. good olive oil
2 T. unsalted butter
2 lb. yellow onions, peeled and sliced in half-rounds
1/2 t. fresh thyme leaves (I omitted this)
2 T. sherry vinegar (I used balsamic)
1 t. kosher salt
1/2 t. freshly ground pepper
Heat the olive oil and butter in a large shallow pot, add the onions and thyme, and toss with the oil. Place the lid on top and cook over medium-low heat for about 10 minutes to sweat the onions. Remove the lid and continue to cook over medium-low heat, stirring occasionally, for about 25 to 30 minutes, until the onions are caramelized and golden brown. If the onions are cooking too fast, lower the heat. Add the vinegar, salt and pepper and cook for 2 more minutes, scraping the brown bits from the pan. Season to taste (they should be very highly seasoned).
