Instructions
Flank Steak
- Prepare your flank steak by trimming any excess fat.
- Mix your marinade ingredients together and place in large sealed bag with flank steak. Allow to marinade for an hour over overnight.
- Be sure to remove your steak one hour before cooking to allow to come to room temperature for more even cooking.
- If you have a cast iron grill pan, or any grill pan - you'll want to use that. Otherwise, a traditional skillet works well. Heat your pan on high for 5 minutes until hot.
- Place your flank steak down and allow to sear for 2-3 minutes. You'll know your steak is ready when you see grill/sear marks and browned.
- Flip and repeat on second side for 3-4 minutes.
- You can use a thermometer to check for doneness.
Insert thermometer into the thickest part of the steak: 120F for very rare, 125F for rare and 130F for medium rare. You don't want to cook beyond that. - Remove pan from heat. Allow steak to rest for 10 minutes before slicing.
Mushroom Sauce
- In a small saucepan on medium heat, add your toum - if you are using minced garlic, add 1 teaspoon olive oil and heat garlic until JUST fragrant. Quickly add your soup and water.
- Whisk until just combined and add your seasonings.
- I always taste before adding salt, especially since the soup is already seasoned. Adjust accordingly.
Mushroom + Onion Mixture
- In a 10" skillet, or something similar heat 2 tablespoons olive oil on medium-high heat. Add your onions and cook for 5 minutes until they begin to brown slightly and become translucent.
- Add a teaspoon of kosher salt* and continue to cook for another 5 or more minutes.
- I prefer my onions NOT to be fully caramelized for this dish but you certainly can continue cooking to caramelize.
- Remove onions from pan, set aside.
- Add 2 tablespoons of olive oil into the same skillet on medium-high heat.
- Add your mushrooms and begin to cook for 3-4 minutes until they soften.
- As they begin to soften add your toum or minced garlic and cook for another 3-4 minutes.
- Salt at the very END, salting early will release moisture into the mushrooms.
- Combine your onions and mushrooms and season as needed. Set aside.
Assembling
- When you're ready to enjoy your steak sandwiches, take your Kaiser or hard rolls and smear a bit of toum or olive oil on the inside. Place rolls on a sheet pan and into the oven on broil.
- Allow the rolls to brown, this gives a good base for the steak sandwich components and won't make it soggy.
- Once rolls are toasted, begin adding your ingredients -
a smear of mushroom sauce
a few slices of steak
onion mushroom mixture
more mushroom sauce
cheese
jalapeños
peppers
shredded cabbage
or whatever other toppings you'd like to include... - Place filled sandwiches back into oven on broil for 3-4 minutes until tops are crisp and cheese melts.
- Enjoy!
Notes
- Different types of salt have different levels of saltiness - I always season and taste along the way to make sure I have my flavors balanced. Kosher salt tends to be LESS salty than table salt. If using table salt, be sure to HALF the measurement and begin there.
- An alternative to cooking a whole flank steak is to purchase pre-sliced carne asada or even thinly sliced beef. Season the same way and cook in a hot skillet in batches.
- All components can be made ahead and assembled the same you're ready to eat.
- Meat can be frozen up to 3 months in sealed packaging. I like to wrap in plastic wrap, then foil and pop into a sealed freezer bag for optimum freshness.
