Key Takeaways:
- Slice the chicken before marinating: Cutting the chicken breasts into strips before marinating helps coat more of the chicken with the flavorful marinade.
- Use fresh lime juice: Lime juice adds bright acidity that balances the spices and complements the chicken.
- Marinate for flavor: This recipe calls for a 2-hour marinade, giving the chicken plenty of time to absorb the seasoning.
- Cook the chicken in batches: Avoid overcrowding the skillet so the chicken can brown instead of steaming.
- Don’t forget the peppers and onions: Red, yellow, and orange bell peppers add color, sweetness, texture, and flavor to the fajitas.
- Customize the toppings: Serve with avocado, salsa, sour cream, cilantro lime crema, cheese, or fresh lime juice.
- Choose your tortilla: Flour tortillas work beautifully, while corn tortillas provide a gluten-free serving option.
Overview
Chicken fajitas are a Tex-Mex-style meal made with seasoned or marinated chicken cooked with sliced peppers and onions and served in warm tortillas. This version uses boneless, skinless chicken breasts sliced into strips and marinated with lime juice, oil, chili powder, onion powder, paprika, cumin, and red pepper flakes before cooking. The key to flavorful chicken fajitas is allowing the chicken strips to marinate before cooking. Slicing the chicken first gives the marinade more surface area to work with and helps distribute the seasoning throughout the meat. The chicken is then cooked until browned and fully cooked, while the peppers and onions are sautéed until tender and lightly caramelized.
SIS Tip - Simple is Smart
For extra-tender chicken strips packed with flavor, slice the chicken breasts into strips before marinating. This allows the marinade to fully infuse the chicken, rather than marinating and cooking the breasts whole before slicing them.
Neuro-Nutrition Nugget
Did you know that red, yellow, and orange sweet peppers are not only flavorful and colorful, but they can also support better brain nutrition? These vibrant vegetables are loaded with important nutrients that help promote healthy brain function. Whether you enjoy the sweetness of red peppers, the bright flavor of yellow peppers, or the mild taste of orange peppers, adding them to your meals can provide valuable benefits for your brain.
One of the most important nutrients found in red, yellow, and orange sweet peppers is vitamin C. These colorful vegetables are an excellent source of this powerful antioxidant, which helps protect brain cells from oxidative damage caused by free radicals. Vitamin C also supports the production of neurotransmitters, the chemical messengers that help brain cells communicate with one another. Including sweet peppers in your diet can therefore help provide your brain with nutrients needed for healthy function.
Sweet peppers are also a good source of vitamin B6, an essential nutrient involved in the production of important neurotransmitters, including serotonin and norepinephrine. These chemical messengers play a role in mood, sleep, and cognitive function. Regularly enjoying red, yellow, and orange sweet peppers can help supply your body with vitamin B6 to support these important brain processes.
In addition to vitamins C and B6, sweet peppers provide other brain-supporting nutrients, including folate and vitamin E. Folate plays an important role in normal brain function and overall mental health, while vitamin E works as an antioxidant to help protect cells from oxidative stress. By adding a colorful variety of red, yellow, and orange sweet peppers to your meals, you can enjoy a delicious way to increase your intake of nutrients that support a healthy brain.
