Chicken Fajitas – The EASY Way!

Being born and raised in Texas, I consider myself a connoisseur of fajitas. I have always scoffed a little at the idea of doing them on a sheet pan.

But I can admit when I am wrong. These Sheet Pan Chicken Fajitas really do bring you all the flavor of the original — minus the dishes, spatter on the stove top and need to hover over it while cooking. It is the best way to make EASY chicken fajitas at home!

If I had hours on end, and someone to clean up after me, I would forever make my skillet chicken fajitas, or even do grilled chicken fajitas, but for a quick chicken fajitas everyone will love, THIS.IS.IT!

What I LOVE about this recipe:

• All in one– The meat… the veggies… they all cook together so you aren’t juggling multiple dishes, cook times, etc
• Non-existent clean up – Only one sheet pan is needed for cooking. Outside of that, just a cutting board and knife.
• TONS of FLAVOR! All the delicious fajita flavor… just less work!
• No babysitting- No need to stand over a pan stirring, once you pop this in the oven, you are free to do whatever you need until the timer goes off!
• Fast Cook time – Because of the method we use, the cook time is super quick so this is great for busy nights.
• Makes AMAZING leftovers! We generally eat this as fajitas day 1, but look forward to the leftovers because we use those for quesadillas, salads, wraps, enchiladas, burritos and more!

I could keep going and going! This recipe for making chicken fajitas in the oven is really a staple for a busy family!

What to Serve with Chicken Fajitas

Traditional fajitas served at a Mexican restaurant will generally come with the fajita set up. This is a plate that includes the following:

• Mexican rice
• Refried beans
• Shredded lettuce
• Sour cream
• Guacamole
• Pico de gallo
• Shredded cheese (in tex mex style fajitas)
• Flour tortillas

You can stick with this just as it is served at the restaurant, or mix it up to include other family favorites! Our family likes fajitas with my crock pot black beans, corn salsa, and a drizzle of jalapeno ranch. Do what you love!

Recipe Notes

This Sheet Pan Chicken Fajitas recipe is as simple as promised! Just a few ingredients and a baking sheet for a family friendly meal.

In this section I am going to go through a few tips and tricks I use when making this recipe to get the absolute best and most delicious results.

Ingredients + Substitutions

• Chicken breast– I use about 1.5 pounds of chicken breast in this recipe. It seems to be just the right amount for a large sheet pan. Chicken breast is traditional for chicken fajitas, but you can use chicken tenderloins as a substitute.
• Yellow onion- I like yellow onion, but you can use white or red in this recipe. Any of the three will caramelize to sweet perfection once baked.
• Bell peppers- The perfect fajitas have a combination of green pepper and a sweeter pepper like red, orange or yellow. The green peppers are less sweet and the brighter colored peppers more sweet for a great flavor combo. I like to use half green and then divide the other half with the sweeter colored peppers.
• Fajita seasoning – You can use store bought seasoning found on the spice aisle, or the Mexican food section. If you have 5 minutes though, I highly recommend using my homemade Fajita seasoning. It is quick, easy and SO good!
• Oil– you can use your favorite high heat tolerant oil. I generally use vegetable or canola oil
• Lime– I highly recommend using fresh lime

Recipe Tips

1. Slice thin! Make both the slices of chicken and the vegetables very thin so that they are able to all cook quickly in the hot oven.
   
2. Spread in a single layer. Try as hard as you can to spread everything (and especially the meat) in a single layer on the baking sheet. The reason for this is that it will cook more evenly. If the meat is piled on top of each other, you will have some areas that are done, while the areas that are piled up need to be cooked longer to cook through.
   |
3. Use a LARGE sheet pan. Because as we discussed above, you want everything in a single layer, you will need a big sheet pan to get everything to fit. If you don’t have a large sheet pan, you can use two smaller pans instead.
   
4. Don’t over cook. The biggest secret to getting tender juicy chicken is not over cooking it. Chicken should be cooked to an internal temperature of 165˚F. Since we are working with thin strips of meat, in a very hot oven, it happens quickly!
   
5. Season at the beginning AND the end. The method I like to use is seasoning the meat at the beginning, then cooking the fajitas and then doing an additional squeeze of lime juice over everything to give it a really fresh flavor. Even better add chopped cilantro too!

Scaling the Recipe

If you find yourself wanting to make more than 4 servings of chicken fajitas, or want extra for meal prep, you can double, triple, or even quadruple the recipe, BUT you will need to use a separate pan for each “recipe.”

So a doubled recipe would need 2 large sheet pans, or a tripled 3 sheet pans etc. You can cook multiple pans at one time if your oven is big enough. Otherwise, you should just cook them in batches.

Recipe Short Cuts

If you need to make this recipe, but are extra short on time, here are a few ideas that can help make this recipe even faster!

• Pre-cut the veggie and meat– this can be done up to 4-5 days in advance, or however long before your meat is due to expire. Once the meat and veggies are cut, I store them in separate containers in the refrigerator.
• Pre-season the meat– The chicken can also be seasoned with the oil and fajita seasoning up to 24 hours in advance. I prefer to add the lime no more than 4 hours before the cooking time though since the strong acidity can start to break down the meat when left too long.
• Prepare as a freezer meal– You can have this meal prepped and ready to cook up to 6 months in advance using the freezer method. Find all the details on this below.

Recipe Variations

If you love this recipe as much as we do and want some quick ways to change it up for variety, these little tips will do the trick!

• Spicy Chicken Fajitas– By default this is a pretty mild recipe, to make spicy chicken fajitas, add 1/4-1/2 tsp cayenne pepper to the fajita seasoning. Then slice fresh jalapeño peppers to cook along with the veggies.
  
• Loaded Veggie Chicken Fajitas– If you like a big variety of vegetables in your fajitas, you can add squash, zucchini, mushrooms, and even tomatoes into the veggie mixture. If you add too many extra veggies you may need to cook them on a separate sheet pan.
  
• Extra Cheesy Chicken Fajitas– This recipe contains cheese/dairy only as an optional topping after prepared. If you like your fajitas extra cheesy, then you can remove from the oven once done, then sprinkle with cheddar or Mexican blend cheese and return to the oven for 2-3 minutes or until cheese is melted. Then serve as desired.
