Ingredients
- Fresh orange juice: adds sweetness and makes the chicken extra juicy Always try to use freshly squeezed orange juice for the brightest possible flavor
- Lime juice: brings tang and helps tenderize the meat The more tart your limes the better the finished flavor
- Olive oil or avocado oil: helps every spice cling to the chicken plus ensures succulence Use a good quality oil for best taste
- Fresh garlic: gives rich pungency Buy whole heads and mince yourself for great depth of flavor
- Cilantro: lends a fresh herby finish Use bright green leaves with no yellowing or brown edges For cilantro haters parsley works too
- Jalapeño (optional): offers heat Slice thin and leave in or out as you like More seeds mean more spice
- Onion powder: spreads savory aroma throughout each piece of chicken Make sure your onion powder is fresh not clumpy
- Chili powder: seasons with warmth Choose one fresh from the spice rack
- Cumin: builds a smoky earthy note Use whole seeds you grind yourself for the most fragrance
- Dried oregano: traditional in fajitas adds green herbal complexity Mexican oregano is punchier if you can find it
- Crushed red pepper flakes: deliver a spark of heat Add more or less as you prefer
- Salt and pepper: finish and heighten all the flavors Always use kosher salt and grind peppercorns fresh for best taste
Step-by-Step Instructions
- Mix the Marinade:
- Whisk together orange juice lime juice oil garlic cilantro jalapeño onion powder chili powder cumin oregano red pepper flakes salt and pepper in a large bowl Mix thoroughly so the oil and citrus become a unified dressing
- Marinate the Chicken:
- Place your chicken in a large ziptop bag or a shallow glass dish Pour in the marinade making sure every piece is coated Massage gently or toss to cover all sides
- Chill and Marinate:
- Cover and place in the refrigerator for a minimum of twenty minutes but ideally two to three hours This allows the acid to tenderize and the spices to infuse If you go longer than twelve hours the texture can get soft so set a timer if marinating overnight
- Cook or Grill Chicken:
- Remove the chicken from the marinade and shake off excess Discard marinade that touched raw chicken Grill or cook as desired until the inside is no longer pink and juices run clear The high heat helps caramelize the sugars from the marinade for an extra layer of flavor
- Serve and Enjoy:
- Slice the chicken against the grain for the most tenderness Serve in warm tortillas and top with your favorite fajita fixings like sautéed bell peppers and onions

My favorite part of this dish is watching the color and aroma come alive after the marinade hits the chicken Every time I make it I think of a summer night when we made fajitas on the grill with my sister and neither of us could stop sneaking bites hot off the barbecue
Storage Tips
Pour extra marinade in a jar and store in the fridge for up to one week Make sure if you want to save some for sauce or drizzling it has not touched raw meat Otherwise freeze any chicken and marinade together in a freezer bag for up to three months and thaw overnight in the refrigerator before cooking
Ingredient Substitutions
No cilantro Try parsley or even a bit of fresh oregano No orange juice Mix pineapple or apple juice for a slightly different fruity note Sensitive to heat Skip the jalapeño and pepper flakes entirely or swap with a dash of mild paprika
