As I was caramelizing onions for a goat cheese and puff pastry dish I was testing out a few weeks ago, I started looking for other vehicles for one of my favorite flavors. I am not a huge fan of raw yellow onion, but with a little olive oil and some time in a skillet, they become tender and gain just a hint of sweetness. This sandwich is a simple blend of caramelized onions with four other classic flavors: steak, Dijon mustard, mayo, and a crusty baguette.
Steak Sandwiches
Makes approx. 4 sandwiches, based on amount of meat
-Flank steak (1 lb-1.5 lbs)
-1 thick baguette or bread of your choice, sliced sandwich-sized
-2 medium yellow onions, cut into thin rings
-1/2 cup mayo
-2 tbs. grained Dijon mustard
-2 tbs olive oil
-Salt and pepper to taste
1) Season the steak with salt and pepper on both sides, and place on a baking sheet coated with tinfoil. Broil to desired doneness, flipping halfway through, and tent with foil for 10 minutes to rest the meat. This will help retain the juices while cutting.
2) While the steak is broiling, heat the olive oil in the skillet and add the onion. Cook over medium-low heat, stirring often to avoid burning, until they are browned and tender. This should take 15-20 minutes.
3) Once the meat is resting, toast the bread slices (if desired) at 400ยบ for 3-5 minutes.
4) Mix the mayo and mustard in a cup and add salt and pepper to taste. Spread a thin layer on each side of the bread.
5) Slice the steak into thin strips. Create a layer of caramelized onions on the bottom half of the bread and cover with three strips of steak. Top with the other half of the bread and slice down the middle.
