How long should you marinate the chicken for chicken fajitas?

You’ll get great flavor if you marinate the chicken for at least 15 minutes, but for deeper seasoning it’s best to let it sit for 1 hour or even overnight. This gives the fajita seasoning and lime juice time to tenderise the meat and infuse flavor.

Can you make chicken fajitas in the oven or on a sheet pan?

Yes — you can spread the seasoned chicken, bell peppers and onions on a sheet pan, bake at around 425 °F for 20–25 minutes and still end up with juicy chicken and crisp-tender veggies. It’s a convenient one-pan method when you want minimal cleanup.

Are chicken fajitas healthy?

They definitely can be. Using lean chicken breasts, plenty of fresh bell peppers and onions, a homemade seasoning blend and serving in corn tortillas or over greens helps keep this meal high in protein and vegetables and moderate in calories. Your choice of toppings and sides will affect the final nutrition.

What’s the difference between fajitas and tacos?

While both are built with tortillas and filling, fajitas typically feature meat (or vegetables) seared with bell peppers and onions and served sizzling in a skillet, often with the option for DIY assembly. Tacos are usually pre-assembled (or not) and can have a broader variety of fillings and styles.

How should you store and reheat leftover chicken fajitas?

Store the cooked chicken-and-veggie mix in an airtight container in the fridge for up to 3–4 days. To reheat, warm gently in a skillet so the chicken stays juicy and the peppers retain texture. If you choose to freeze, keep the chicken and veggies separated from tortillas, freeze for up to 2 months, then thaw overnight before reheating.

Instructions

Whisk olive oil, lime juice, and spices together in a bowl, then add sliced chicken and marinate for at least 15 minutes.
Heat olive oil in a skillet over medium-high heat. Add sliced onions and bell peppers; sauté until slightly softened and charred, then remove and set aside.
In the same skillet, cook marinated chicken for 5–6 minutes until golden and cooked through.
Return vegetables to the skillet, toss to combine, and squeeze fresh lime juice over the top.
Serve the mixture in warm tortillas with your favorite toppings like sour cream, salsa, or guacamole.

Notes

Marinate longer for deeper flavor—up to 2 hours if time allows.

Use a cast-iron skillet for the best sear and authentic restaurant-style char.

For meal prep, store the filling separately and assemble fajitas just before serving.
