Jibarito Sandwich Recipe with Flank Steak and Aioli is a Puerto Rican Chicago staple with flank steak that is topped off with a homemade aioli!
Dude, I’m not even kidding, I may like jibarito sandwiches more than I like burgers. And I work with a burger chain here in Chicago. I mean dude they are just so good. I’ve always said when things are in their simplest forms they are at their most delicious!
I mean it’s essentially a burger but with fried plantains instead of a bun and flank steak, or any other steak even burger meat if you want it, instead of an actual burger patty. That’s it! For some reason though when all of the flavors of it are married together it’s like an explosion of deliciousness.
I will say this, however, just like in my roast beef sandwich, because of the plantains a jibarito sandwich does take a minute to prep up but don’t let that hold you back because these are the new burgers
How to Make it
Whenever I cook anything, especially this jibarito, I am always about prepping first before anything. There is nothing worse than having to stop and cut or prep something in the middle of cooking because I forgot about it. After years of culinary training and practice
I don’t do that too often anymore but it does happen on occasion. The first thing to do is the prep up the flank steak for this jibarito sandwich recipe and it’s super easy.
Now when it comes to marinades I always say try and let it sit in the fridge overnight before cooking it so if you can do that with this recipe than I highly recommend you do so.
If you can’t, no problem just marinate it at the beginning of prepping up this recipe, so it’ll sit for about an hour and a half. Don’t worry this will still be delicious!
The flavors in this sandwich marinade are salty with a tad bit of spicy acid but don’t worry it is very light on the heat. Whisk together some adobo sauce from chipotles, oil (whichever one you prefer), salt, lime juice, and sugar.
The lime juice and sugar are there to offset the spice from the chipotle but again the heat is very mild so if you do like spicy, load this thing up with more adobo sauce or chipotles.
Add the marinade to a plastic bag and add in the steak and move it around so that the marinade covers the steak completely and pop it in the fridge until It’s time to cook it or overnight to make sure this jibarito is full-flavored!
How to Make the Aioli
The next thing in our prep repertoire is the garlic aioli and the veggies that will go on our sandwich.
The aioli for this is a basic aioli consisting of mayonnaise, salt, lemon juice, and finely minced garlic, that’s it.
You could add pepper if you want and if you do want to get super fancy faced go ahead and make homemade mayonnaise, that would be very extra gangster of you should you do that!
The other toppings for it are your basic burger stuff consisting of sliced tomatoes, green leaf lettuce, and thinly sliced onions.
You can completely change this up by using roasted tomatoes, heirlooms, iceberg lettuce, red leaf lettuce, sweet onions, I don’t care about this part you pick!
How to Make Tostones
The final and longest part of the prep for this is the plantains.
Now, this is not a hard procedure at all but like I said it will take some time, probably around 30 minutes or so, but once you’re prepped you will fly through making these delicious sandwiches!
In case you were wondering, the plantain buns for the jibarito are also known as tostones.
Find yourself some nice ripe green plantains, which are the savory kind, no they are not bananas and then peel them.
Be gentle peeling them because you want to make sure they keep their shape so your sandwich isn’t all jacked up. Cut them in thirds and then slice them in half.
It’s hard to imagine at this point but these will act as your buns for the jibarito. Fry these sliced up plantains in some oil that’s about 350° to 375° for 3 to 4 minutes per side. You won’t be able to tell if they are done just by constantly checking, just trust me on the temperature and time!
Next, you need to smash these fellas and if you’ve got a tortilla maker then you’re in business because all you need to do is add them in there and smash them up! If not no problem, just use the backside of a pan.
Don’t worry, these aren’t going to look awesome, they may be a bit hideous and that’s just a part of this jibarito sandwich.
Now refry the flattened plantains for about 2 minutes just to crisp them up a bit more and then it’s time to sear up the flank steak! I like medium-rare flank steak because I think it’s more tender that way so pan sear it up and slice it on a bias and against the grain very thin so that it’s the most tender piece of meat ever!
Plate up time! Fried plantain, aioli, American cheese, lettuce, sliced cooked flank steak, sliced tomatoes, sliced onions, aioli and top fried plantain and boom a jibarito sandwich. ENJOY!
