Juicy, smoky chicken with charred peppers and sweet onions—the dish in your photo is perfect for meal prep and tastes even better the next day.
🛒 Ingredients
For the chicken & vegetables
- 1½–2 lb (700–900 g) boneless, skinless chicken breast or thighs
- 1 large red bell pepper
- 1 large green bell pepper
- 1 large yellow or orange bell pepper
- 1 large yellow onion
- 3 tbsp olive oil
- 3 cloves garlic, minced
- 1½ tbsp chili powder
- 2 tsp smoked paprika
- 1½ tsp ground cumin
- 1 tsp dried oregano
- 1 tsp onion powder
- ½ tsp black pepper
- 1 tsp salt
- ½ tsp cayenne pepper, optional
- Juice of 1 lime
For serving
- Warm flour or corn tortillas
- Sour cream
- Avocado or guacamole
- Shredded cheese
- Fresh cilantro
- Lime wedges
- Salsa or pico de gallo
🔪 Preparation
- Prepare the chicken:
Pat the chicken dry and cut it into bite-size pieces. Keeping the pieces relatively similar in size helps them cook evenly. - Slice the vegetables:
Cut the peppers into thin strips and slice the onion into wedges or strips. Don’t make them too thin—they should remain slightly crisp after roasting. - Make the seasoning:
In a large bowl, combine chili powder, smoked paprika, cumin, oregano, onion powder, salt, black pepper, and cayenne. - Marinate everything:
Add the chicken, peppers, and onions to the bowl. Add olive oil, minced garlic, and lime juice. Toss thoroughly until everything is coated with the seasoning mixture. For the best flavor, cover and refrigerate for 30 minutes to 2 hours. If you’re short on time, you can cook it immediately.
🔥 Cooking
- Preheat the oven:
Heat your oven to 425°F (220°C). For extra browning, let the baking sheet heat in the oven while it preheats. - Arrange the fajitas:
Spread the chicken, peppers, and onions across the baking sheet in a single layer. Avoid piling everything on top of each other. Crowding causes the vegetables to steam instead of becoming beautifully charred. - Roast:
Bake for approximately 20–25 minutes, stirring once halfway through. - Get that restaurant-style char:
For the final 2–4 minutes, switch the oven to broil/high grill. Watch closely—the edges should become browned and slightly charred without burning. - Check the chicken:
The thickest pieces should reach 165°F (74°C) internally. - Finish:
Remove from the oven and squeeze fresh lime juice over everything. Let the chicken rest for about 5 minutes before serving.
🌮 How to Serve
Warm your tortillas, then pile them high with the chicken, peppers, and onions. Top with:
- A spoonful of guacamole
- Sour cream
- Fresh cilantro
- Pico de gallo or salsa
- Shredded cheese
- A squeeze of fresh lime
⭐ Best Tips for Extra Flavor
- Use chicken thighs if you want especially juicy, tender chicken.
- Don’t overcrowd the pan—this is the biggest secret to getting the browned edges shown in your photo.
- Smoked paprika gives the chicken a delicious grilled flavor.
- Letting the chicken marinate for at least 30 minutes makes a noticeable difference.
- For even more char, finish under the broiler for a few minutes.
- Add sliced jalapeños if you like your fajitas spicy.
🍱 Meal Prep
Divide the cooked chicken and vegetables into 4–5 containers. Refrigerate and use within 3–4 days. Reheat in a skillet or microwave and serve with rice, tortillas, salad, or avocado.
My favorite combination: chicken + peppers + onions over cilantro-lime rice, topped with guacamole, fresh salsa, and a squeeze of lime.
