Chicken Fajitas (Oven Baked) — A Little Tex-Mex Magic for the Just-for-Us Nights

Cookbook testing: enchiladas week. Elena's green chile chicken enchiladas — the Twentynine Palms napkin recipe. The recipe that changed my cooking and became our Christmas Eve tradition. Made them four times. The first three were for calibration — how much green chile, how much cheese, how long in the oven (every oven is different, so the recipe needs temperature RANGES, not absolutes — a lesson from nine base-housing ovens). The headnote writes itself: 'I met a woman in Twentynine Palms, California, the worst duty station I've ever endured. She handed me a napkin with a recipe for green chile chicken enchiladas. I didn't catch her last name. I kept her recipe. It became our Christmas Eve tradition and the recipe my children will associate with every December. Wherever you are, Elena — thank you.' The fourth batch was for Pri, who declared them 'excellent but you need more lime in the crema.' She's right. She's always right about lime. Caleb is deep into the summer reading program at the library. He's read eight books in two weeks — all about ocean animals. The dinosaur era may be ending. The marine biology era is beginning. 'Mama, octopuses have THREE HEARTS.' 'I know.' 'Can we get an octopus?' 'No.' 'Can we get a dog?' 'No.' 'Can we get ANYTHING?' 'You can get a library book.' The negotiation skills of a six-year-old. (Almost six. November.) Made the enchiladas for Friday dinner. The non-test batch. The just-for-us batch. Elena's enchiladas. The napkin recipe. The tradition.

After four rounds of enchilada testing and a Friday dinner that was purely, joyfully ours, I found myself still in a Tex-Mex frame of mind — the kind that wants bold spices, tender chicken, and something that comes together without a lot of fuss. These oven-baked chicken fajitas are the weeknight answer to that craving: everything goes on one pan, the oven does the work, and the result is the kind of colorful, sizzling dinner that makes Caleb ask for seconds before he’s finished his first plate. Sometimes the best follow-up to a tradition is something simple and bright that keeps the same spirit going.

Chicken Fajitas (Oven Baked)

Prep Time: 15 minutes | Cook Time: 25 minutes | Total Time: 40 minutes | Servings: 4

Ingredients

• 1 1/2 lbs boneless, skinless chicken breasts, sliced into thin strips
• 3 bell peppers (red, yellow, and green), sliced into strips
• 1 large yellow onion, sliced into strips
• 3 tablespoons olive oil
• 2 teaspoons chili powder
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 teaspoon cayenne pepper (optional)
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• Juice of 1 lime
• 8 medium flour or corn tortillas, warmed
• Optional toppings: sour cream, shredded cheese, salsa, avocado, fresh cilantro, lime wedges

Instructions

1. Preheat the oven. Heat your oven to 425°F (or 400°F convection). Line a large rimmed baking sheet — or two if needed to avoid crowding — with foil and set aside.
2. Make the seasoning. In a large bowl, whisk together the olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, cayenne (if using), salt, pepper, and lime juice until combined.
3. Coat the chicken and vegetables. Add the sliced chicken, bell peppers, and onion to the bowl. Toss everything together until evenly coated with the seasoning mixture.
4. Spread on the baking sheet. Arrange the chicken and vegetables in a single layer on the prepared baking sheet. Do not pile them up — a single layer ensures everything roasts rather than steams.
5. Bake. Roast in the preheated oven for 20–25 minutes, until the chicken is cooked through (internal temperature 165°F) and the peppers and onions are tender with lightly caramelized edges.
6. Broil for color (optional). For slightly charred edges, switch the oven to broil for the final 2–3 minutes, watching closely.
7. Serve. Pile the chicken and vegetables into warm tortillas and add your toppings of choice. Squeeze an extra wedge of lime over everything — Pri is right, more lime is always the right call.
