Fajitas are the perfect weeknight meal. Start the meat marinating earlier in the day and you are guaranteed a flavorful dinner! They cook up quick and easy. Pair with colorful sliced bell peppers and onions and load into soft flour tortillas for a filling dish. Serve alongside some charro beans, and some cilantro lime rice for a complete Tex Mex meal.

Why use this marinade?

  • The combination of lime and pineapple juice tenderizes the meat used in the dish giving you tender, juicy meat every time!
  • Using few seasonings and spices allows the true flavorings of the meat to still shine in the this recipe without being overpowering.
  • This marinade comes together quick and easy with mostly pantry items or items typically kept in the home.
  • Control what goes into your food by making your own homemade marinades.

Ingredients Needed for Homemade Fajita Marinade:

Notes on some ingredients:

  • Pineapple Juice: my preference is to buy the cans of Dole Pineapple juice, if you plan on making a large batch or using the juice for other recipes or drinks a large can will work, otherwise get a pack of small cans so you’re not wasting and keep them in the pantry.
  • Lime Juice: fresh squeezed juice is always best!
  • Soy Sauce: I use regular soy sauce in this recipe since I want the extra salt when marinading.

How to Make Fajita Marinade and How to Use It:

  • Prepare the marinade by combining the ingredients in a large jar, or small bowl.
  • Marinate the meat you are using (either chicken or skirt steak) in a sealed container or large sealed plastic bag.
  • Let the meat marinate for at least 3-6 hours. I don’t recommend leaving the meat to marinade overnight since the pineapple juice can start to make the meat turn mushy.

Tip: Be sure to set aside a couple tablespoons of marinade for grilling the veggies in at the end.

Cooking the meat:

Once the meat has marinated for 3-6 hours cook in a large cast iron skillet, chicken should be cooked to 165℉, steak to desired doneness (135-140℉ for medium rare) remove from the skillet and let rest on a cutting board while you grill the bell peppers and onions in the remaining marinade.
