Easy Chicken Fajitas

There was a Tuesday night when I had exactly thirty minutes before soccer practice and a fridge full of bell peppers that were one day away from looking sad. I grabbed the chicken, sliced everything without measuring a single spice, and threw it all into my oldest skillet. The smoke alarm went off twice, the lime rolled under the fridge, and somehow those fajitas became the meal my kids ask for every single week. Sometimes the best recipes are born from chaos and hunger.

I made these for a friend who swore she hated cooking, and she texted me a photo of her own version three days later with the caption finally something I didnt ruin. Watching someone discover that weeknight cooking doesnt have to be stressful or perfect is better than any compliment. We ended up having a fajita night at her place the following month, and she admitted she had made them four times in two weeks.

Ingredients

• Boneless, skinless chicken breasts: Slice them thin so they cook fast and soak up all that lime and spice, and if theyre partially frozen theyre actually easier to cut evenly.
• Red, yellow, and green bell peppers: The mix of colors isnt just pretty, each one has a slightly different sweetness that builds flavor, and they hold up to high heat without turning to mush.
• Large onion: Slice it thick so it gets caramelized edges and stays a little bit crunchy, which adds texture against the soft tortillas.
• Olive oil: This helps the spices stick to the chicken and keeps everything from sticking to the pan when the heat gets high.
• Chili powder, cumin, smoked paprika: These three are the backbone of that Tex-Mex flavor, and smoked paprika is the secret that makes people ask what you did differently.
• Garlic powder and onion powder: They distribute flavor more evenly than fresh in a quick marinade, and they help create that beautiful crust on the chicken.
• Salt and black pepper: Dont skimp here because they bring out the sweetness in the peppers and the tang in the lime.
• Lime juice: Fresh lime is the only way to go, it brightens everything and cuts through the richness in a way bottled juice never will.
• Flour or corn tortillas: Warm them until theyre pliable and slightly toasted, and they become the perfect vehicle for all that sizzling goodness.
• Fresh cilantro, sour cream, salsa, shredded cheese: These toppings turn a simple fajita into a customizable feast, and everyone gets to build their plate exactly how they like it.

Instructions

Mix the marinade and coat the chicken:

In a large bowl, whisk together the olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, pepper, and lime juice until it looks like a rusty orange paste. Toss the sliced chicken in until every piece is coated, then let it sit for at least ten minutes while you slice the vegetables.

Cook the chicken until golden:

Heat your skillet over medium-high until it just starts to smoke, then add the chicken in a single layer and let it sit for a minute before stirring so it gets those dark, crispy edges. Cook for five to six minutes, stirring occasionally, until the chicken is cooked through and has little charred bits, then remove it to a plate.

Sauté the peppers and onion:

Add a splash of oil to the same pan if it looks dry, then toss in the bell peppers and onion, stirring every minute or so to get some color on them. Let them cook for four to five minutes until theyre tender but still have a little snap, and the edges are blistered and sweet.

Combine everything and heat through:

Slide the chicken back into the pan with the vegetables and toss everything together for one to two minutes so the flavors meld and everything is piping hot. The smell at this point will make everyone appear in the kitchen asking when dinner is ready.

Warm the tortillas:

Heat them in a dry skillet for about ten seconds per side until theyre soft and have a few brown spots, or wrap them in a damp towel and microwave for thirty seconds.

Assemble and serve:

Pile the chicken and vegetables into the warm tortillas, then let everyone add their own cilantro, sour cream, salsa, or cheese. Stand back and watch them disappear.

One night I made a double batch and packed the leftovers for lunch the next day, and my coworker leaned over and said it smells like vacation in here. We ended up sitting outside eating reheated fajitas and talking about summer plans, and it reminded me that food has this way of turning ordinary moments into something you remember. That lunch break became a weekly thing, and now we call it Fajita Friday even though it's usually Thursday.

Making It Your Own

The first time I swapped the chicken for shrimp I was nervous it would cook too fast, but it turned out even better because shrimp loves high heat and lime. You can also use flank steak sliced thin against the grain, or pressed tofu if you want to skip the meat entirely. I have a friend who adds pineapple chunks in the last two minutes of cooking, and as weird as it sounds the sweetness against the smoky spices is incredible.

Serving Suggestions

I like to put out little bowls of toppings and let everyone build their own because it feels like a tiny party even on a Wednesday. Guacamole, pickled jalapeños, a squeeze of extra lime, and some crumbled queso fresco all make it feel more special without any extra work. Serve it with a simple side of black beans or Mexican rice, and youve got a meal that feels complete without feeling heavy.

Storage and Leftovers

Leftover fajita filling keeps in the fridge for up to three days and reheats beautifully in a hot skillet with a splash of water to bring back the moisture. I have used cold leftovers in a salad with some romaine, corn, and a drizzle of lime dressing, and it was somehow better than the original dinner. You can also freeze the cooked filling in a zip-top bag for up to two months, then thaw and reheat when you need dinner in a hurry.

• Store the tortillas separately so they dont get soggy from the filling.
• Reheat in a skillet instead of the microwave to bring back that slightly charred texture.
• If the filling seems dry after storing, add a squeeze of lime and a drizzle of olive oil before reheating.

These fajitas have saved more weeknights than I can count, and theyve never felt boring or like a chore to make. I hope they become your easy answer to the whats for dinner question, because everyone deserves a meal that tastes this good without the stress.

Recipe FAQs

→ Can I use other proteins instead of chicken?

Yes, you can substitute beef strips, shrimp, or tofu for the chicken. Adjust cooking times accordingly—shrimp cooks faster while beef may need a bit longer.

Absolutely. You can marinate the chicken up to 24 hours in advance. Store it covered in the refrigerator for best results and maximum flavor.

→ What's the best way to get charred vegetables?

Use high heat and avoid overcrowding the pan. Let the vegetables sit without stirring for a minute or two to develop those delicious charred edges.

Store the cooked chicken and vegetables separately from tortillas in airtight containers in the refrigerator for up to 3 days. Reheat in a skillet over medium heat.

→ Can I make these fajitas spicier?

Yes, add sliced jalapeños to the vegetables, include a pinch of cayenne pepper in the marinade, or serve with hot sauce for extra heat.
