This high-protein chicken fajitas recipe delivers 27 grams of protein per serving with a bold spice blend that actually takes effort to get right. The overnight marinade turns basic chicken breast into something that tastes like it came off a restaurant grill, and the whole thing comes together in a single skillet. Great for meal prep Sunday or a weeknight dinner that doesn’t feel like diet food.

What Makes This Actually Good

• The spice blend is built with chili powder as the base, smoked paprika for depth, and a touch of cayenne that adds heat without overpowering the chicken.
• Marinating the chicken in a zip-top bag means every corner gets coated in seasoning, and butterflying the breasts creates more surface area for the spice rub to work into.
• Cooking the chicken on medium heat for 5 to 8 minutes per side gives you a nice sear on the outside while keeping the inside juicy and fully cooked.
• Each serving packs 27 grams of protein at just 240 calories, which makes it easy to hit your daily targets without sacrificing flavor.

Ingredients

• Chicken Breast. Trim the fat and butterfly for even cooking.
• Avocado Oil. Adds healthy fats and helps everything brown evenly in the skillet. 2 tablespoons for the chicken, 1 tablespoon for the peppers.
• Chili Powder. The main flavor driver for the whole spice blend. A full 2 tablespoons gives you that classic fajita taste without any heat.
• Smoked Paprika. It brings a smoky depth you normally only get from an outdoor grill.
• Ground Cumin. Earthy and warm. A tablespoon is a generous amount, but cumin is what makes fajitas taste like fajitas instead of just seasoned chicken.
• Garlic Powder. Garlic. Not the jarred stuff. It makes a noticeable difference when you’re building a dry rub.
• Onion Powder. Complements the fresh onion you’ll sauté alongside the peppers. Double onion layer adds complexity.
• Dried Oregano. A small amount goes a long way. Ties the spice blend together with a subtle herbal note.
• Salt. 1 teaspoon seasons the chicken through without making it taste like a deli slice.
• Black Pepper. Freshly cracked if you’ve got it, but pre-ground works fine for a marinade this bold.
• Cayenne Pepper. Optional heat. Half a teaspoon adds a slow burn without turning the whole thing into a fire hazard.
• Lime. You’ll use half for the chicken marinade and half for the peppers. Brightness cuts through all the spice.
• Honey. Just a tablespoon. Balances the heat from the cayenne and keeps the chicken from tasting like a spice rack.
• Red Pepper. The star of the pepper medley. Sweet and colorful, it caramelizes nicely in the skillet.
• Yellow Pepper. Adds a slightly milder sweetness that rounds out the mix alongside the red and green peppers.
• Green Pepper. Bell pepper. A classic fajita component that holds its crunch through the sauté.
• White Onion. Half a onion sliced and sautéed until soft. Sweeter than yellow onion when cooked down.
• Fresh Cilantro. Garnish. Tear it on right before serving for the freshest flavor.
• Salsa. Toss it on top or serve it on the side. Your call.
• Avocado. Sliced and ready to go. Adds creaminess and healthy fats to balance the spice.
• Sour Cream. Cool and rich. A dollop offsets the cayenne heat really well.

Reasons This Will Become a Regular

• 27 grams of protein and only 240 calories per serving makes this one of the most macro-efficient dinners you can put on the table.
• The marinade goes together in one bag, so cleanup is basically washing a bowl and a skillet.
• Butterflying the chicken breasts means they cook faster and more evenly than whole pieces ever would.
• Three colored peppers give you a visually striking plate that looks like restaurant quality without any plating skills.
• The spice blend is flexible enough to adjust heat level to your preference. Skip the cayenne for a family that doesn’t like spice.
• Leftovers reheat beautifully in a skillet or microwave, which makes this a solid meal prep candidate for the whole week.
• You probably already have every spice in this recipe on hand. No specialty grocery runs required.

What Goes Well With This

• Cilantro Lime Chicken (balances the spice and turns this into a full meal)
• Cooked black beans or pinto beans, filling enough to make it a complete bowl
• Warm flour or tortillas, the classic vessel for wrapping up every bit of chicken and peppers
• Simple side salad with lime juice and olive oil, keeps the meal from feeling too heavy on weeknights
• Mexican street corn (elote) style corn kernels for a sweet and creamy contrast to the smoky chicken

Ways to Make This Yours

• Shrimp Fajitas. Swap the chicken breast for peeled and deveined shrimp. Cook time drops to 3 to 4 minutes per side, so watch it closely.
• Steak Fajitas. Flank skirt steak works here too. Marinate it the same way and grill it to medium rare for a different protein experience.
• Veggie Fajitas. Drop the chicken entirely and double the peppers plus add a zucchini or two. Serve over cauliflower rice for a lower carb option.
• Air Fryer Version. Toss the marinated chicken pieces in the air fryer at 400F for 12 to 14 minutes. Less active monitoring, same flavor.
• Taco Bowl Format. Skip the plating and toss everything over a bed of greens or rice for a deconstructed fajita bowl that’s just as satisfying. If you want the same fajita flavors in a handheld format, Ground Turkey Fajita Wraps use a similar spice blend with lean ground turkey.

Notes

For best flavor, marinate the chicken overnight. The spice blend gets even more complex as it sits.
