Ingredients for Skillet Chicken Fajitas with Peppers

Okay, let’s gather our fajita dream team! I’ve learned the hard way that prepping everything before you start cooking makes this recipe fly by. (Trust me, no one wants to be frantically slicing peppers while the chicken burns.) Here’s what you’ll need:

For the Fajitas

  • 1 lb boneless, skinless chicken breasts – sliced into strips (I make mine about ½-inch thick so they cook evenly)
  • 2 bell peppers – sliced (I’m partial to using one red and one yellow for color, but any combo works!)
  • 1 onion – sliced (yellow onions are my go-to for that perfect sweet-savory balance)
  • 2 tbsp olive oil – for that beautiful sizzle
  • 1 tbsp fajita seasoning – store-bought is fine, but I’ll share my homemade blend trick later!
  • 8 flour tortillas – warmed (more on how I do this perfectly below)

For Serving

  • Sour cream – optional (but in my house, it’s mandatory)
  • Guacamole – optional (said no one ever)
  • Salsa – optional (but why wouldn’t you?)

See? Nothing fancy, just fresh, simple ingredients that transform into something magical. Now let’s get cooking!

How to Make Skillet Chicken Fajitas with Peppers

Alright, let’s get sizzling! I’ve made these skillet chicken fajitas with peppers so many times I could probably do it in my sleep (and honestly, some nights I practically do). Here’s my foolproof method for getting that perfect char and juicy chicken every single time:

  1. Heat that oil like you mean it – Crank your burner to medium-high and let your skillet get properly hot before adding the oil. You’ll know it’s ready when a drop of water dances across the surface. Add the olive oil and swirl it around – that shimmer means business!
  2. Chicken time! – Add your sliced chicken in a single layer (no crowding, or you’ll steam instead of sear). Let it cook undisturbed for about 3 minutes until you see that beautiful golden crust forming underneath. Flip and cook another 2-3 minutes until no pink remains. Pro tip: resist the urge to constantly stir – those browned bits equal flavor!
  3. Veggie party – Push the chicken to one side and toss in your peppers and onions. I love that instant sizzle sound! Let them cook about 5 minutes, stirring occasionally, until they’re tender-crisp with some charred edges. This is when my kitchen smells like my favorite Mexican restaurant.
  4. Seasoning magic – Sprinkle the fajita seasoning evenly over everything and give it a good stir. The heat will wake up all those spices – you’ll actually see the color deepen right before your eyes. Cook for just 1 more minute to let the flavors marry.
  5. Serve with flair – Pile everything onto a warm platter (I use my trusty cast iron for that rustic look) with tortillas and toppings on the side. Watch everyone’s eyes light up when you bring it to the table still sizzling!

My secret weapon: If I have even 30 extra minutes, I’ll toss the chicken with half the seasoning and a splash of lime juice before cooking. That quick marinade makes the chicken insanely flavorful and tender. But honestly? Even without marinating, these fajitas are weeknight gold. And if you’re craving more quick chicken dinners, my 15-minute chicken stir fry is another family favorite!

Tips for Perfect Skillet Chicken Fajitas with Peppers

After making these skillet chicken fajitas with peppers more times than I can count (seriously, my family requests them weekly), I’ve picked up some tricks that take them from good to “oh my goodness, can I have thirds?” Here’s what I’ve learned:

Slice like you mean it: Cut your chicken into even strips—about ½-inch thick—so everything cooks at the same rate. Nothing worse than some pieces being done while others are still pink in the middle! I use kitchen shears for this job while the chicken is still slightly frozen; it’s way easier.

Get that pan screaming hot: Medium-high heat isn’t a suggestion, it’s the law for perfect fajitas. You want that satisfying sizzle when the chicken hits the oil. If your smoke detector goes off, you’re probably doing it right (just kidding… mostly).

Give them space to breathe: Don’t dump everything in at once unless you want steamed veggies instead of beautifully charred ones. I cook in batches if needed—it’s worth the extra few minutes for that restaurant-quality sear.

Keep those veggies lively: The peppers and onions should still have some crunch when you take them off the heat. They’ll keep cooking a bit from residual heat anyway, and that texture contrast with the tender chicken is everything.

My pepper confession: I’m obsessed with using one red and one yellow bell pepper—not just for the gorgeous color (though that’s a bonus), but because the red ones are sweeter while the yellows have this bright, almost citrusy note. Green peppers? Only in emergencies. The flavor just doesn’t sing the same way to me!

Serving Suggestions for Skillet Chicken Fajitas with Peppers

Now for the best part – loading up those warm tortillas with all the goodies! In our house, we turn fajita night into a full-on fiesta with a toppings bar. Here’s how I like to serve these skillet chicken fajitas with peppers:

The must-have toppings: Cool sour cream (I always have extra because my kids use it like frosting), chunky guacamole (my secret? a splash of lime juice and plenty of salt), and your favorite salsa. We usually do a mild one for the kids and a spicy verde for the adults. Oh, and don’t forget the shredded cheese – cheddar or Monterey Jack both work beautifully.

Tortilla trick: Warming your tortillas makes ALL the difference. I either wrap them in a damp paper towel and microwave for 30 seconds, or char them directly over my gas burner for about 10 seconds per side (watch them closely!). That little bit of heat makes them pliable and brings out their flavor.

Perfect sides: A big pot of Mexican rice (my go-to recipe) and some smoky black beans complete the meal. Sometimes I’ll even whip up a quick corn salad if I’m feeling fancy. The best part? Leftovers make amazing lunch wraps the next day!

Storage and Reheating Instructions

Okay, let’s talk leftovers – because let’s be real, I always make extra of these skillet chicken fajitas with peppers on purpose! Here’s how to keep them tasting amazing:

Fridge storage: Pack the chicken and pepper mixture (without tortillas) in an airtight container. It’ll stay fresh for 3 days – though in my house, it never lasts that long! Pro tip: Store any toppings separately so everything stays fresh.

Reheating magic: My favorite method is tossing everything back in the skillet over medium heat for 2-3 minutes. The veggies keep their texture and the chicken stays juicy. If you’re in a rush, the microwave works too – just cover with a damp paper towel and heat in 30-second bursts, stirring between.

Emergency warning: Whatever you do, don’t store the fajita mix with the tortillas unless you want a sad, soggy mess! I learned this the hard way after packing my husband’s lunch once. Now I send tortillas in a separate baggie with reheating instructions taped to the container. Marriage saved!

FAQs About Skillet Chicken Fajitas with Peppers

I get asked about these skillet chicken fajitas with peppers all the time – here are the questions that pop up most often in my kitchen (and my honest answers!):

Can I use frozen peppers instead of fresh?

Sure, in a pinch! Frozen peppers will work, but they’ll be softer – that fresh crunch is half the fun of fajitas. If you do use frozen, pat them dry really well before cooking to avoid a watery mess. Personally? I keep a bag of sliced peppers in my freezer for emergencies, but fresh is always my first choice for texture and flavor.

How can I make these fajitas spicier?

Oh, I love this question! Toss in some sliced jalapeños with your bell peppers – seeds and all if you’re brave. You could also use a spicy fajita seasoning or add a pinch of cayenne. My husband’s favorite trick? Drizzling everything with hot sauce before serving. Just warn your guests if you go wild with the heat – I may or may not have made this mistake at a family gathering once!

Can I swap the chicken for shrimp?

Absolutely! Shrimp fajitas are amazing – just reduce the cook time to about 2-3 minutes per side (shrimp cooks crazy fast). I like to use large, peeled shrimp and add them after the veggies are mostly done. Pro tip: squeeze fresh lime over the shrimp at the end for a bright pop of flavor. Now I’m craving seafood fajitas… might need to make those tonight!
