• 2 tsp chili powder
• 1.5 tsp ground cumin
• 1 tsp smoked paprika

4. Arrange the seasoned chicken on top of the peppers and onions, spacing pieces out so they roast, not steam.
5. Roast for 18–22 minutes, until the chicken is cooked through (165°F) and edges of veggies begin to char.
6. Broil for 2–3 minutes if you want extra char. Watch closely.
7. Squeeze the lime juice over everything and toss right on the pan.Taste and adjust salt.

Keeping It Fresh

– Store cooked fajitas in an airtight container for up to 4 days. – Reheat in a hot skillet for 2–3 minutes to revive char and keep the peppers crisp. – Freeze cooked chicken only (without peppers) for up to 2 months; add fresh peppers when reheating for best texture.

Benefits of This Recipe

– Fast and reliable: Dinner on the table in about 30 minutes. – Customizable: Dial the heat up or down and swap proteins. – Balanced plate: Lean protein, colorful veggies, and fiber from corn tortillas or whole-wheat flour tortillas.

What Not to Do

– Don’t overcrowd the pan. Overlapping pieces lead to steaming, not charring. – Don’t cut chicken too thick.

Thinner strips cook quickly and stay juicy. – Don’t skip the lime. The acidity brightens the spices and lifts the whole dish. – Don’t under-season. Taste and add a pinch of salt after roasting if needed.

Alternatives

– Protein swaps: Use shrimp (roast 8–10 minutes), steak (slice thin and roast 10–12 minutes), or tofu (press well, toss with cornstarch and spices, roast 20–25 minutes). – Veggie upgrades: Add mushrooms or zucchini; slice similarly to peppers for even cooking. – Tortilla swaps: Try lettuce wraps for a lighter take or serve over rice/cauliflower rice for a bowl.

Can I use store-bought fajita seasoning?

Yes. Use 1.5–2 tablespoons for this amount of chicken and veggies.

Taste and add salt if the blend is low-sodium.

How do I keep the chicken from drying out?

Slice it thin, roast hot and fast, and avoid overcooking. Pull it at 165°F and finish with lime juice for extra moisture.

Should I marinate longer?

Even 10–15 minutes helps. If you have time, marinate up to 4 hours in the fridge for deeper flavor.

Can I prep this ahead?

Absolutely.

Slice everything and mix the spices the day before. Keep chicken and veggies separate until cooking to avoid sogginess.

What toppings work best?

Avocado, cilantro, salsa, pickled jalapeños, shredded cheese, and a quick lime-yogurt crema all shine. Warm tortillas are a must.
