Ingredients
- Boneless skinless chicken breasts: provide lean quick-cooking protein. Choose ones that are plump and firm for best results
- Olive oil: infuses the dish with richness while helping the Cajun seasoning cling to the chicken and veggies. Use extra virgin for deeper flavor
- Cajun seasoning: gives the dish its signature spicy smoky edge. A homemade mix tastes fresher but your favorite store brand works too
- Garlic powder: boosts flavor and blends smoothly into your spice mix
- Onion powder: enhances savoriness and is easy to sprinkle on evenly
- Paprika: supplies warmth and brings a beautiful color. Look for bright red sweet paprika for depth
- Dried thyme: adds earthiness that balances the bolder spices
- Salt: ties the seasonings together. Use fine sea salt for even seasoning
- Black pepper: lends sharpness and a mild touch of heat
- Bell peppers: in red green or yellow add natural sweetness and a fun crunch. Choose glossy firm peppers for best flavor
- Onion: brings a mellow bite and caramelizes slightly as it cooks
- Fresh garlic: heightens aroma and authentic Cajun flavor
- Parsley or cilantro for garnish: gives a fresh herbal lift right before serving. Choose perky leaves for best color and flavor
Step-by-Step Instructions
- Mix the Cajun Seasoning:
- Combine Cajun seasoning garlic powder onion powder paprika thyme salt and black pepper in a small bowl. Stir until everything is thoroughly blended. This step ensures even coverage and powerful Louisiana flavor
- Season and Sear the Chicken:
- Pat chicken breasts dry with paper towels so the spices do not slip off. Rub each piece evenly with your Cajun mix. Heat olive oil in a large skillet over medium-high until it shimmers. Sear chicken for about six to seven minutes per side until the surface is deep golden and the juices run clear. Remove chicken to a plate to rest which helps keep it juicy
- Sauté the Peppers and Onion:
- Add another splash of olive oil to the same skillet. Add sliced bell peppers and onions spreading them out so they soften instead of steam. Cook for five to six minutes stirring occasionally until they become tender. Once soft add fresh minced garlic and stir until just fragrant
- Slice and Return the Chicken:
- Cut your rested chicken into thin strips. Return it to the skillet with the peppers and onions. Toss everything gently to coat in pan juices and let the flavors blend over medium heat for two to three minutes
- Finish and Serve:
- Turn off the heat. Shower the skillet with a handful of chopped fresh parsley or cilantro. Serve hot with your choice of side like rice quinoa or salad

I love using fresh paprika in my Cajun mix for an extra punch of color and flavor. My kids always got excited watching the bright peppers sizzle in the pan and now it has become one of their all-time favorites to help with on busy nights.
Storage Tips
Leftovers keep very well in an airtight container for up to three days in the fridge. Reheat gently in a skillet over low heat or in the microwave. If freezing cool completely before packing into freezer-safe containers then thaw overnight in the refrigerator and warm through before serving.

Chicken thighs make a juicier option and taste just as good with the spices. Bell peppers can be swapped for zucchini squash mushrooms or even broccoli so use what you have on hand. For more heat toss in a little cayenne. If you do not have Cajun seasoning use a mix of paprika smoked paprika black pepper garlic powder onion powder and thyme with a pinch of salt.
