Weeknight Skillet Fajitas Recipe
Prep Time: 15 minutes
Cook Time: 15 minutes
Total Time: About 30 minutes
Servings: 4–6
Ingredients
For the Fajitas
- 1 ½ pounds boneless, skinless chicken breasts or chicken thighs
- 1 red bell pepper
- 1 green bell pepper
- 1 yellow or orange bell pepper
- 1 large yellow onion
- 2 tablespoons olive oil, divided
- 2 cloves garlic, minced
- Juice of 1 lime
- 8–12 small flour or corn tortillas
Homemade Fajita Seasoning
- 2 teaspoons chili powder
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon cayenne pepper, optional
Optional Toppings
- Shredded cheddar or Mexican-blend cheese
- Sour cream
- Guacamole
- Sliced avocado
- Pico de gallo
- Salsa
- Chopped cilantro
- Sliced jalapeños
- Lime wedges
- Hot sauce
- Shredded lettuce
Step 1: Prepare the Ingredients
Slice the chicken into thin strips. Try to keep the pieces roughly the same thickness so they cook evenly.
Remove the stems and seeds from the bell peppers and slice them into strips.
Slice the onion into thin wedges.
Having everything prepared before you start cooking is particularly helpful with fajitas because the cooking process moves quickly once the skillet gets hot.
Step 2: Make the Fajita Seasoning
In a small bowl, combine the chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, black pepper, and optional cayenne pepper.
Mix thoroughly.
Homemade fajita seasoning takes only a minute to prepare and allows you to adjust the flavor exactly how you like it.
If you prefer milder fajitas, leave out the cayenne.
Want more heat? Add additional cayenne or crushed red pepper flakes.
Step 3: Season the Chicken
Place the sliced chicken in a bowl.
Drizzle with about 1 tablespoon of olive oil and sprinkle approximately two-thirds of the fajita seasoning over the chicken.
Toss until every piece is evenly coated.
For even more flavor, you can season the chicken earlier in the day and refrigerate it until dinner.
Step 4: Cook the Chicken
Heat a large cast-iron or heavy-bottomed skillet over medium-high heat.
Once the skillet is hot, add the seasoned chicken.
Spread the pieces into a relatively even layer and allow them to cook without constantly stirring them. Giving the chicken time against the hot surface helps create those delicious browned edges associated with restaurant-style fajitas.
Cook for approximately 5–7 minutes, stirring occasionally, until the chicken is cooked through.
The USDA recommends cooking poultry to an internal temperature of 165°F.
Transfer the cooked chicken to a clean plate and set aside.
Step 5: Cook the Peppers and Onions
Add the remaining tablespoon of olive oil to the same skillet.
Add the sliced bell peppers and onions.
Sprinkle the remaining fajita seasoning over the vegetables.
Cook for approximately 5–7 minutes, stirring occasionally.
You want the vegetables tender but still slightly crisp. A little browning around the edges adds even more flavor.
During the final minute, add the minced garlic.
Avoid adding the garlic too early because it can burn in the hot skillet.
Step 6: Bring Everything Together
Return the cooked chicken to the skillet with the peppers and onions.
Pour the fresh lime juice over everything.
Toss until the chicken and vegetables are thoroughly combined.
Cook for another minute or two until everything is hot.
Taste and adjust the seasoning if necessary.
Then bring that sizzling skillet straight to the table.
Don’t Forget to Warm the Tortillas
Warm tortillas make a surprisingly big difference.
You can heat tortillas individually in a dry skillet for about 20–30 seconds per side.
For an easier method, stack several tortillas together, wrap them in a slightly damp paper towel, and microwave them briefly until warm and flexible.
Keep them covered until you’re ready to eat so they don’t dry out.
Build Your Perfect Fajita
Now comes the fun part.
Place some chicken, peppers, and onions down the center of a warm tortilla.
Then start adding toppings.
One delicious combination is:
Chicken fajita mixture, shredded cheese, pico de gallo, guacamole, sour cream, cilantro, and a squeeze of fresh lime.
If you love spicy food, finish everything with sliced jalapeños or your favorite hot sauce.
Fold the tortilla and enjoy.
The Secret to Better Skillet Fajitas
The biggest mistake when making skillet fajitas is overcrowding the pan.
When too much food is packed into the skillet at once, moisture gets trapped. Instead of developing browned edges, the ingredients begin steaming.
If your skillet isn’t large enough, cook the chicken in two batches.
A cast-iron skillet works particularly well because it retains heat and helps produce a flavorful sear.
Another important trick is getting the skillet properly hot before adding the meat.
That initial blast of heat helps create the sizzling, slightly charred exterior that makes fajitas so good.
Make Steak Fajitas
Prefer beef?
This recipe works wonderfully with steak.
Try using:
- Flank steak
- Skirt steak
- Sirloin
- Flat iron steak
Slice the steak thinly against the grain and season it using the same fajita mixture.
Cook quickly over high heat and avoid overcooking it.
Once cooked, remove the steak while preparing the vegetables and return it to the skillet at the end.
Make Shrimp Fajitas
Shrimp turns this already-fast recipe into an even quicker dinner.
Use peeled and deveined shrimp and coat them with the fajita seasoning.
Shrimp generally needs only a few minutes in a hot skillet. Cook until pink, opaque, and cooked through, remove from the skillet, and prepare the vegetables.
Return the shrimp at the very end so it doesn’t become overcooked and rubbery.
Make Vegetarian Skillet Fajitas
You don’t need meat to make delicious fajitas.
Increase the amount of peppers and onions and add vegetables such as:
- Mushrooms
- Zucchini
- Corn
- Yellow squash
- Poblano peppers
You could also add black beans for extra protein and texture.
Portobello mushrooms are particularly good because their hearty texture stands up well to high-heat skillet cooking.
Turn Them Into Fajita Bowls
Skip the tortillas entirely and transform this recipe into fajita bowls.
Start with rice or another grain and pile the chicken and vegetables over the top.
Add black beans, corn, salsa, avocado, cilantro, cheese, and lime.
You can also serve the fajita mixture over chopped lettuce for a lighter fajita salad.
What to Serve With Skillet Fajitas
Fajitas can easily be a complete meal by themselves, but side dishes can turn them into an even bigger dinner.
Try serving them with:
Mexican-style rice: A classic side that pairs perfectly with the smoky seasonings.
Black beans: Simple, filling, and delicious alongside fajitas.
Refried beans: Another traditional choice that’s especially good topped with cheese.
Corn: Grilled or skillet-cooked corn complements the peppers beautifully.
Chips and salsa: Keep things easy with a bowl of tortilla chips and your favorite salsa.
Guacamole: Fresh avocado, lime, cilantro, onion, and seasonings create the perfect fajita companion.
Meal Prep Idea
Weeknight Skillet Fajitas are also excellent for meal prep.
Cook the chicken, peppers, and onions as directed and divide the mixture into meal-prep containers.
Add rice and beans if desired.
Store the tortillas separately so they don’t become soggy.
You’ll have an easy lunch or dinner ready to reheat during the week.
Storing Leftovers
Allow leftover fajita filling to cool before transferring it to an airtight container.
Refrigerate promptly and use within 3–4 days.
Keep tortillas and toppings such as sour cream, guacamole, lettuce, and salsa separate from the hot filling.
This prevents everything from becoming soggy.
Reheating Fajitas
The skillet is one of the best ways to reheat leftover fajitas.
Heat a skillet over medium heat, add the chicken and vegetables, and cook until heated thoroughly.
You can also microwave individual portions when you’re short on time.
Add a fresh squeeze of lime after reheating to brighten everything back up.
Easy Ways to Change the Flavor
One reason fajitas make such a great weeknight dinner is how easy they are to customize.
Try adding sliced poblano peppers for a slightly smoky flavor.
Add chipotle powder for extra heat.
Use freshly squeezed orange and lime juice for a citrus marinade.
Add fresh jalapeños while cooking the vegetables.
Experiment with different proteins.
You can even combine chicken and steak for a restaurant-style mixed fajita platter.
A Great Dinner for Feeding a Crowd
Fajitas are also an easy meal when friends or family come over.
Instead of trying to figure out everyone’s favorite toppings, create a fajita bar.
Set out warm tortillas, the sizzling fajita mixture, cheese, salsa, guacamole, sour cream, jalapeños, cilantro, lettuce, and lime wedges.
Everyone gets to create exactly what they want.
Double or triple the recipe depending on how many people you’re serving and cook the meat in batches so the skillet stays hot.
