Marinade for Chicken Fajitas

When I don’t know what to make for dinner but I have chicken, this chicken fajita marinade is my go-to. In just 20 minutes, it infuses the chicken with all the flavor you need for a dinnertime win.

While the chicken sizzles, I sip on my best margarita recipe and dip chips into some spicy guacamole. When the chicken is ready, I wrap it all up in warm tortillas and turn it into easy chicken fajita tacos.

How Long to Marinate Chicken for Fajitas

20 to 30 minutes is long enough to infuse the chicken with all the flavors in the marinade, but no more than 8 hours. At that point, the acid in the lime juice begins to break down the proteins and change the texture of the chicken.

Tips for the Most Flavorful Marinade

Cut whole breasts or thighs into fajita strips or smaller pieces before marinating. The more the chicken is exposed to the marinade, the more flavorful.
Prep the marinade ahead, but avoid over-marinating. If you want to save time, mix the marinade a day ahead, but remember that the chicken only needs 20 minutes.
Fresh lime juice makes a big difference in the flavor and the tenderizing of the protein.
Don’t skip the oil. It helps the spices and herbs get into the meat. You’ll discard the marinade anyway.
Use a marinade bag or smaller dish so the marinade covers as much of the chicken as possible.

Variations

Fresh herbs: chop up some fresh cilantro, lemon thyme, or fresh oregano instead of the dried in the recipe.
Fresh aromatics: swap the garlic powder for 2 garlic cloves, finely minced or grated.
Use orange juice instead of lime. This citrus pairs great with all the spices.
Make it spicier by adding 1 tablespoon of minced chipotle peppers in adobo, ½ teaspoon of red chili flakes, or by chopping up ½ of a jalapeño.
