Fajita Seasoning Breakdown
Homemade is always best, but store-bought is fine. For the DIY crowd, mix up:
- 1 tbsp chili powder
- 2 tsp ground cumin
- 1 tsp smoked paprika
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp dried oregano

Pro tip: Make a double batch and keep it in a jar. You’ll want this on everything.
Step-by-Step: How to Make Fajita Chicken Sheet Pan Dinner
1. Prep the Veggies and Chicken
Slice everything into thin, even strips for fast, even cooking. Toss chicken and veggies with olive oil and seasoning right on the sheet pan.
2. Spread Everything Out
Arrange in a single, even layer. Crowded pans = steamed veggies. Space = crispy edges.
3. Roast
Bake at 425°F for about 20-25 minutes, stirring once, until chicken is cooked through and veggies are caramelized at the edges.
4. Serve and Enjoy
Squeeze over fresh lime, sprinkle with cilantro, and serve hot with tortillas and all your favorite fixings.

Nutrition Takeaway:
This fajita chicken sheet pan dinner is protein-packed, low in carbs (before tortillas), and loaded with vitamin C and antioxidants from all those peppers. Toss it in a tortilla, or go naked (the fajita, not you—unless it’s that kind of dinner party) and serve over salad for a lighter twist.
Why Sheet Pan Fajitas Rock for Meal Prep
- Portion out leftovers for lunch: They’re just as tasty reheated.
- Pack with tortillas for work or school: DIY fajita wraps all week.
- Freeze extras: The chicken and veggies hold up great for future meals.
- Switch up the flavor: Add black beans, corn, or roasted sweet potato to keep things interesting.
Make It Your Own: Fun Variations
- Spicy: Extra jalapeños or a dash of hot sauce pre-bake
- Cheesy: Add shredded cheese at the end and pop back in the oven for 2 minutes
- Vegan: Swap chicken for tofu or chickpeas (use the same seasoning)
- Extra filling: Serve with brown rice, cauliflower rice, or salad greens
My Experience: From “Meh” to Must-Make
I used to dread weeknight cooking. Now, I look forward to sheet pan nights! The first time I tried this, my kitchen actually smelled so good that my neighbors texted to ask what I was making (true story). There’s something satisfying about tossing everything on a pan, walking away, and coming back to a complete meal. Plus, there’s no fighting over cleanup. 😏
Side Note: Common Mistake
Don’t overcook the chicken! Thin strips cook fast—so check at the 18-minute mark. Dry chicken = sad fajita.
What to Serve with Your Fajita Chicken Sheet Pan Dinner
- Warm tortillas (corn or flour)
- Fresh guacamole or sliced avocado
- Chunky salsa or pico de gallo
- Greek yogurt or sour cream
- Lime wedges
- Cilantro and extra veggies
Or, for a lighter option, skip the tortillas and pile it on greens for a fajita salad.
