How to serve Steak Fajitas
When you make Fajitas, you already have the base of a full meal with a protein and veggies.
To take it from good to great, you need to add some toppings and a couple of sides.
What to put in Fajitas
I like to offer a variety of toppings so that each person can customize their own fajita. This makes not only for a kid pleasing dinner, but also a great option for entertaining or having a party.
Start with a tortilla- you can use flour or corn based on preference. Then add all the toppings you want… or that your fajita can hold!
Here are my favorite toppings for fajitas:
Got the toppings! So what goes well with fajitas?
Sides for Fajitas
- Mexican rice
- Refried or black beans
- Chips – served with salsa, guacamole or queso
- Green chile cheddar mashed potatoes (not traditional but we love it!)
How much fajita meat do you need per person?
You should account for 4 oz of raw meat per person when served with vegetables, rice, and beans. If there are no sides, you should estimate 8 oz of steak per person.
Cooking Secrets – How to Make Steak Fajitas
As I mentioned above, the beauty of these steak fajitas is all in the method.
I am going to walk through my tips and tricks here, to help answer any questions that might pop up, but you will find the full recipe card at the bottom of this post.
What is the best steak for fajitas?
I prefer to use skirt steak for fajitas. I think it offers the best combination of tenderness and flavor, plus it was the original meat that was used when fajitas were first created!
Flank steak, hanger steak and sirloin flap all have a similar texture and taste and can be good substitutes as well.
I like to keep it traditional with my fajitas. Although these days you will see everything from mushrooms, to cauliflower and more in fajitas, this recipe just calls for the classics- bell pepper and onion.
You can use any color bell pepper you want for fajitas, but I really like to use 1 green and 1 red, yellow and orange. Since the red, yellow, and orange peppers have a sweeter taste than the green peppers it gives a bit more depth of flavor.
I highly recommend using a homemade fajita seasoning because it gives the best flavor without the fillers.
This homemade fajita seasoning I use only takes minutes to put together, and it will keep in your cabinet for as long as a year.
Another added bonus of fajita seasoning made from scratch is that it is friendly for gluten free, dairy free, and low carb diets. So if you are cooking for a special diet, make sure to use homemade since many packages on the shelf don’t comply with these restrictions.
Our 4 Step method (The Secret Sauce!)
The method in cooking these beef fajitas is both what makes them so delicious and what makes them so easy! It is a simple 3 step process:
- Prep the ingredients
- Cook on high heat
- The signature fajita sizzle
We use HIGH HEAT in this recipe so things move fast!
TIP: Make sure to have all of your ingredients prepped and ready before starting to cook so you can keep up with the pace for the best results!
In some fajita recipes you will cook the steak as a whole, and then slice it after it is cooked. In our recipe you will pre-slice the skirt steak.
This is important because it allows the steak to cook quickly in the skillet.
The veggies should also be sliced into uniform strips.
How long to cook steak fajitas
We use high heat to give the outside of the skirt steak and vegetables the delicious caramelization that makes the flavor so good!
Since the heat is so high, it only takes just a couple of minutes to get them cooked to where we want them. You also have to keep a careful eye on them so that you don’t leave them on too long and burn or over cook both the steak and vegetables.
The vegetables will take about 3-4 minutes and I like to cook these first for 2 reasons.
- The vegetables will continue to cook and soften as they sit
- This allows you to serve the steak as hot, fresh and sizzling as possible
The steak fajitas will take about 4-5 minutes total to cook, done in steps.
- First lay the steak in the pan in a single layer- getting it as spread out and flat as possible will add more flavor. Resist the urge to stir, you want it to sit 2-3 minutes so it get get that nice rich brown caramelization on the out side.
- Flip the steak to the other side. I find that almost as soon as I am done doing this I can move on to the next step.
- Mix in the butter, garlic and lime juice. Since the skillet and steak are so hot, these cook almost instantly, so you can remove the skillet from the heat and serve while the fajitas are still sizzling!
This last step is where you get that signature sizzle for your fajitas.
When you add the butter garlic and lime juice into the skillet on high heat, it will immediately produce the sizzle from the moisture in the butter and lime juice.
The combination of these three ingredients also add an insane level of flavor!
Be ready to stir back in the veggies and get your hot sizzling skillet to the table asap!
