At Target Field, they have a really great sandwich - The Murray's Steak Sandwich. It's steak with melted provolone cheese and caramelized onions on ciabatta bread. Granted, the steak is always a little more done than I would like, but still, it's delicious.
So, the last time we were at a Twins game, I decided I had to try making the sandwiches at home. And they were amazing. I could've eaten them even without the steak and been perfectly happy.
Murray's Steak Sandwich
2 steaks (6 oz or so)
2 ciabatta rolls (big enough to fit the steak)
caramelized onions (about 1 1/2 medium onions worth for 2 people)
salt & pepper
Start caramelizing the onions about 45 minutes to one hour before you actually want to eat. Do this by melting about 1 TBSP butter in a big pan with about 1 1/2 tsp olive oil. Let that melt over low heat while you slice your onions. Put them in the pan and sprinkle with just a little bit of sugar (like 1/4 tsp). Stir just a little and let cook for about 10 minutes. After about 10 minutes, sprinkle with just a little salt. Stir. Continue this process for about 45-60 minutes total, stirring about every 10 minutes until the onions get a nice brown color.
After you put salt on the onions, season the steaks with salt & pepper on each side. About 25 minutes before you want to be eating, start heating up a pan on medium high heat. Add about 1 TBSP butter and about 1 TBSP olive oil. Let it heat up for about 5 minutes. Add the steaks and cook 1 minute and then reduce the heat to medium and cook another 3-4 minutes per side for medium rare. Increase the cooking time by about a minute or two per side if you want it more medium.
Let rest for about 5 minutes.
Meanwhile, preheat the broiler (mine has a high and a low setting - if yours does too, put it on low) about 5 minutes before the steaks are done. While the steak is cooking, put cut your ciabatta rolls in half and put cheese on each side of the rolls.
Once you take your steaks out to rest, put the rolls under the broiler for a couple of minutes to melt the cheese. Mine took about 3 minutes.
Once the rolls come out of the oven, put caramelized onions on the bottom of each roll and put the steak on top of the onions. Top with the top half of the ciabatta and enjoy.
