Can You Reuse Fajita Marinade? 

You may be tempted to reuse the marinade straight from the bag, but it will not be safe to use as-is. In fact, the bacteria from the raw meat could make you very, very sick.

All that flavorful fajita marinade doesn't have to go to waste, though: You can make it safe-to-eat by boiling the liquid for several minutes. This process will also reduce the liquid, resulting in a thick sauce that'll work well with your homemade fajitas. .

Allrecipes Community Tips and Praise

“This is an excellent marinade, particularly if you have the time to do it overnight,” according to John McArthur. “When I have less time I add about 50% more lime juice so the acid breaks down the muscle better.”

“This recipe makes fajitas that are addictive,” raves one Allrecipes community member. “And I ought to know — I'm from Texas! I scaled this to 20 servings for a party and used half the marinade for top round steak and half for chicken breasts.”

“I love Mexican food,” says Medora Jensen. “This recipe has resurrected two dishes for my family. Quesadillas and fajitas. I use cooked, left over chicken and shred it with the marinade. I cook some peppers, onions and garlic, add the shredded chicken and voila!”
