Chicken Fajita Skillet
This chicken fajita skillet turns lean chicken breast, sweet bell peppers, and onion into a colorful one-pan dinner in about 25 minutes.
It fits a budget-friendly kitchen because it uses simple grocery staples and one skillet. Chicken breast gives you lean protein, while peppers and onion add fiber, color, and natural sweetness without much cost.
Why You’ll Love This Recipe
- Bold fajita flavor coats every strip of chicken and every soft piece of pepper.
- The chicken stays juicy when you slice it thin and cook it quickly.
- Everything cooks in one skillet, so cleanup stays simple.
- It works as a skillet meal, rice bowl filling, or tortilla filling if you want to stretch it further.
Fabian’s Budget and Health Tip: Use frozen bell pepper strips when fresh peppers cost more. They cook a little faster and still give you sweetness, color, and fiber. If chicken breast is pricey, sliced boneless chicken thighs work well too and stay tender.
Ingredients (Serves 4)
- Chicken breast: 1 pound, 454 grams, sliced into thin strips
- Bell peppers: 2 medium, about 300 grams, sliced, use any colors
- Onion: 1 medium, about 150 grams, sliced
- Fajita seasoning: 2 tablespoons, about 16 grams
- Neutral oil or olive oil: 1 tablespoon, 15 milliliters
- Water: 1 to 2 tablespoons, 15 to 30 milliliters, only if the pan looks dry
Step-by-Step Instructions
1. Slice the Chicken and Vegetables
Slice the chicken breast into thin, even strips so it cooks quickly. Also, slice the bell peppers and onion into similar pieces. Pat the chicken dry so it can sear instead of steam.
2. Sear the Chicken
Heat the oil in a large skillet over medium high heat. Add the chicken in an even layer. Let it sizzle without moving it for 2 minutes, then stir. Cook until the outside looks lightly golden and the chicken no longer looks pink on the surface. Move it to a plate.
3. Soften the Peppers and Onion
Add the sliced peppers and onion to the same skillet. Cook for 5 to 7 minutes, stirring often. The onion should turn glossy, and the pepper edges should soften and pick up a few brown spots. Your kitchen should smell sweet and savory.
4. Add the Seasoning
Return the chicken to the skillet. Sprinkle the fajita seasoning over everything. Stir well so the spices touch the chicken, peppers, and onion. If the spices stick to the pan, add a small splash of water.
5. Finish the Skillet
Cook for 2 to 3 minutes more, until the seasoning turns into a thin glossy coating and the thickest chicken strips reach 165°F, 74°C. The vegetables should be soft but not mushy, and the sauce should cling to the chicken instead of pooling in the pan.
6. Serve It Simply
Serve the chicken fajita skillet hot from the pan. Keep it simple as a low carb skillet meal, or spoon it over rice or into warm tortillas if you want a more filling dinner.
Expert Troubleshooting and FAQs
Can I use frozen chicken?
Yes, but thaw it fully before slicing. Pat it very dry before it hits the skillet. Extra surface moisture will make the chicken steam, and you will miss those golden edges.
Why is my chicken dry?
Chicken breast gets dry when it cooks too long. Slice it evenly, sear it fast, and pull it from the heat once it reaches 165°F, 74°C. Letting it finish with the vegetables for just a few minutes keeps it tender.
Can I make my own fajita seasoning?
Yes. Use a pantry blend of chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and black pepper. Homemade seasoning often costs less per batch than a small store bought packet.
