Grilled Steak Fajitas-7

I did Chicken Fajitas/Quesadillas in the past but I decided to kick them up a bit with some beef in the form of flank steak, blackened peppers, and a Caribbean marinade.

This dish has a lot of components to it but once you get the process down it’s just too easy.  This is also one of those very social dishes that brings everyone together so that they can make their fajita just the way they want it.  As you can see below there are a lot of components here:

Grilled Steak Fajitas-1

Let me break them down for you.


1.5 pounds of flank steak
2 medium chicken breasts (Mom requested chicken so I made some extra)
3 bell peppers, quartered with all seeds and white flesh removed
2 medium size onions, chunked into 6 equal chunks
Fajita shells
1 pound shredded cheese (I recommend shredding your own but preshredded will do)
1/2 cup olive oil and pastry brush
Salsa and sour cream for garnish
One bottle Tobago Keys Steakman’s Marinade
The Bud Light Lime is optional

Let’s start off with the beef.  Below is a very lean 1.5 pound flank steak:

Basically a very lean cut like this is tough and going to need some flavor.  And I have just the thing:

Tobago Keys Steakman’s Marinade. The first ingredient is orange juice.  The smell alone makes me think of my honeymoon in Playa del Carmen.  This stuff just oozes a Caribbean flavor throughout the meat.  And it being highly acidic (the orange juice) it will tenderize quite well.  I’m a big fan of the entire line of Tobago Keys stuff.

Into a plastic bag with enough of the marinade to cover all surfaces and into the fridge overnight:

My parents were coming over and my mom requested some chicken as well as a healthier alternative to the beef.  I had a cuple partial chicken breasts left over in the freezer from a bag of boneless, skinless breasts.  Combined these three pieces make about two medium size breasts.  I realize that the marinade is called Steakman’s Marinade but they are selling themselves short.  In the end the marinade permeated the meat better on the chicken than the steak.  The steak was a great mellow flavor of the Caribbean but the chicken just burst with the flavor:

Also into a bag with the marinade and into the fridge:

Now back to this picture.  Get everything chopped and ready before putting anything on the grill in order to save yourself a lot of time:

Grilled Steak Fajitas-1

Once everything is chopped and ready, throw the chicken on:

Grilled Steak Fajitas-5

Once the chicken is done, pull it off the grill and set aside but do not slice yet.  Now for the flank steak and the peppers.  Directly over a hot fire:

Grilled Steak Fajitas-6

After just 2 minutes flip the flank steak:

After another two minutes remove from the direct heat and continue to cook the peppers.  This is where I made a mistake.  I should’ve pulled the flank steak right here when it was still pretty rare.  Instead I pulled it to the side and closed the lid to hasten the cooking of the peppers which means the steak continued to bake.  I will go into why this was a mistake at the end in the, “What I would do different,” section:

Grilled Steak Fajitas-8

Once the peppers are done take them and the steak inside.  The peppers are done when they have a nice blackened skin and are fairly pliable rather than stiff when they went on the grill.

Now that I have room on the grill again, time for the onions.  While the peppers will not slide through the grill grates when quartered as such, onions will quite easily no matter how big you slice them so I used my grill pan with all the holes in it to do the onions:

Onions have become, soft, translucent and browned up in spots:

Grilled Steak Fajitas-10

Now you are probably asking yourself how the chicken can still be warm at this point.  The easy answer is it’s not.  But each person will stuff a fajita shell with meat, cheese, pepper, onions, etc and it will go back on the grill to brown the shell and thus reheating everything nicely.

Inside with all the ingredients Dad is slicing up the peppers:

Grilled Steak Fajitas-11

Once the peppers are done he tackled the steak which he cut against the grain.  What that means is that those lines are striations that run sort of up and down in the picture above are the grain.  Slicing the knife perpendicular to those lines is slicing against the grain like so:

Grilled Steak Fajitas-12

Here is everything sliced with a bowl of shredded cheese, some fajita shells, the onions in another bowl and some salsa verde (but you can use whichever salsa you prefer).  The steak is a medium rare to medium.  And on it’s own it had great flavor and was very tender.  But it was now sliced into thin pieces and going to go back over a heat source which means it will cook very quickly.  Considering the second round of heat I should’ve pulled it when it was still really rare.  I’m not perfect.  We make mistakes too.  Hopefully you learn from our mistakes without having to make them yourselves:

Grilled Steak Fajitas-13

Here we have dad with a layer of cheese, topped with some beef and some peppers:

Grilled Steak Fajitas-14

Another layer of cheese is added.  Cheese on the top and bottom layer allows for this thing to bind together nicely once it melts:

Grilled Steak Fajitas-15

Dad decided to add some salsa verde as well:

Grilled Steak Fajitas-26

Here are Mom’s two fajitas getting olive oil painted on to keep the shells from burning on the grill:

Grilled Steak Fajitas-17

Before putting anything back on the grill this is a good time to check to see if the fire needs any more fuel.  I added about a dozen briquettes at this time and allowed about five minutes for them to heat up.

Then Mom’s went on first:

Grilled Steak Fajitas-18

Here are all six in various stages of turning:

Grilled Steak Fajitas-19

Being the polite pit master that I am, I cooked mine last:

Grilled Steak Fajitas-20

And here they are plated:

Grilled Steak Fajitas-21

A dollop of sour cream completed the meal.

What I would’ve done differently

  1. Remember that there is a second cooking cycle so pull the beef when it is still pretty rare as it will cook more once back on the grill
  2. While someone else is slicing the peppers, steak, etc, add more coals to the fire to allow them to heat up and save yourself some time.

A couple of notes.

  1. When these things come off the grill they are like molten lava inside so please give them plenty of time to cool
  2. This recipe made a lot more than just enough for six fajitas.  My toddler had some of the steak and chicken and I still have enough for a couple more tonight.  In order to save on charcoal I will simply make these on the stove.  Fajita shell, layer of cheese over half, the leftover ingredients, some salsa, more cheese, fold over and place in a medium high frying pan with a little oil.  Heat till both sides are browned and then plate (again contents of the fajita will be like molten lava)
  3. For those vegetarians out there.  These things are excellent with just peppers, onions, cheese, and salsa.

Looks delicious. My wife is vegetarian and we make our fajitas with peppers, onions, carrots, broccoli, green beans and summer squash. And don’t forget the guacamole!

Good work providing plenty of pics.


That’s the great thing about these things. Just about anything would work. Mushrooms. Zucchini. Tomatoes.

I’m liking the “what I would do different” area on this and the last post! Keep up the good work!


Do you have any smoked ham favorites you could post about. I know it’s simple but I’ve never done it before.
