Healthy Steak Tacos Fillings
Before cooking your steaks, I recommend starting with sauteeing your vegetables. Personally, I like to melt butter in a pan but you can also use oil, then add in the sliced mushrooms, onions, and salt.
Allow that to cook for about 10-15 minutes, stirring frequently and covering the pan to help the vegetables soften. Near the end of cooking, I also like to add some black pepper and fresh herbs!
But, while the vegetables are cooking, feel free to start cooking your flat iron steaks! (See process for cooking & slicing below.)
The final component of these flat iron steak tacos will be the whipped blue cheese spread. To prepare, simply pulse together blue cheese crumbles and whipped cream cheese in a food processor, until creamy. It should only take 1-2 minutes! Once it’s spreadable, you’re ready to assemble your tacos.
When I made this recipe, I used small yellow corn tortillas, added a dab of the whipped blue cheese, then layered in some sliced steak, and finished with the sauteed veggies and a cilantro garnish.
Of course, you’re welcome to make your healthy steak tacos with any tortillas you prefer! Soft flour will work just as well, or try lettuce wraps, jicama shells, or even egg wraps—whatever you enjoy and suits your lifestyle.
How to Cook Flat Iron Steak
Naturally, the most important component of our flat iron steak tacos is going to be the steak. Different cuts of steak will cook a bit differently, so just keep in mind that I’m talking about flat iron steaks throughout this process.
To start, cut your 12oz of steak into 2-4 pieces as needed—smaller pieces will need less time to cook. Then, be sure to season them with salt on both sides.
Heat a large, flat pan over medium-high heat, then add butter to melt or your oil of choice. Once heated, add each piece of steak to the pain and allow them to cook for 5-6 minutes undisturbed, without moving them around.
Next, flip each piece, season with a dash of pepper, and continue to cook for anywhere from 2-10 minutes.
The exact amount of time will vary depending on the thickness of your steaks, the heat of your pan, and your desired level of doneness. (I.e., shorter time for medium-rare, longer time for well-done.)
I like a little pink in my steaks (medium), so an additional 5-6 minutes worked well for me! For more well-done, you may want to continue cooking for 8-10 minutes. Once cooked to your liking, remove from the pan, finish with a squeeze of lemon juice, and allow to rest 5 minutes before slicing.
How to Slice Steak for Tacos
Generally, slicing against the grain is the best option for slicing steak—particularly for flat iron steak tacos like these. By slicing in this way, you break down the meat fibers so they’re more tender, which makes them easier to bite and chew in your tacos.
So, look at your cooked piece of meat, and look for the pattern of lines (a.k.a. ‘the grain’) running across the meat. It’s best to look at the top and all sides of the meat to get a sense of the direction of the grain!
Once you can see the general direction, grab your knife and slice diagonally across the grain, slicing the meat into strips. Continue to slice each piece of meat in this way.
If, after slicing one of your steaks, you notice it’s pinker than you’d like it to be, that’s fine! Simply pause, reheat your pan, and toss the steak back on for another few minutes. Then, allow it to rest once more before slicing into strips. Once sliced, assemble your healthy steak tacos and devour!
