Chicken fajitas in foil.

Hey everyone! It’s Ashley from The Recipe Rebel back with an easy summer dinner you need to add to your repertoire!

I don’t know about you, but we love to take our cooking outside in the summer. It’s fun to come up with new ways to make our favorite dinners on the grill, from Chicken Parmesan to Cheeseburger Pizza!

What I love about these Chicken Fajita Foil Packets is that they are so easy to prep ahead. You can slice up the chicken, peppers and onions, and mix them up with the seasoning and then let them sit — in a container or in their foil packets — in the refrigerator for up to 24 hours.

Recipes like this are perfect for camping, when you’re not going to want to spend a lot of time on meal prep, and those busy days where you’re running from the park to the beach to the grocery store for a refill on popsicles. You can have them ready and waiting, and when 5:00 hits you can fire up the grill and serve with some warm flour tortillas or rice.

Another thing that’s great about these chicken foil packets is that you can adjust the ingredients and the level of spice to suit everyone’s tastes. If a family member is not keen on onions, leave them out. If one likes their fajitas with extra spice, throw in some jalapenos or a dash of sriracha when you’re mixing it up. Vegetarian? Simply leave out the chicken and add in extra veggies like zucchini or mushrooms.

How to Make Chicken Fajita Foil Packets:

  • Double up on the foil: you really don’t want any of that flavor to drip out (and cause flare ups!), so double up on the foil to prevent any leaks.
  • Slice your chicken thin: your peppers and onions won’t take long to cook, and your goal is to have everything ready at the same time. Make sure your chicken slices are thin so they will cook quickly as well.
  • Time saver: if you’re short on time or energy (or both!) feel free to swap out the homemade seasoning for a store bought package. No one will know 🙂

    We love this recipe!! We like it on the grill, in the oven or camping. I was wondering about cooking this in the crockpot. Maybe 4hrs on high?? Need a company meal but not going to be home so it has to go in the crockpot.

  2. Thank you for making the recipes so that I can adjust them down for just the two of us! Sometimes I have to guesstimate the amount of dry ingredients but your things are usually always keepers!!

    Made this tonight and it was a HIT! Cooked in the oven at 400 for 20 minutes to perfection. Great recipe. Thank you for sharing!

  4. I recently noticed this recipe and wanted to try it, but unfortunately my grill is acting up and I need to get it fixed. I’ve noticed some of the other foil pack recipes have oven instructions. Do you have a recommendation for an oven temperature and time for this recipe?

    1. Yes, these are great in the oven too! I have not made this recipe in the oven but it will still work! I would bake them at 400* and for 15-20 minutes checking on them half way through. Let me know how they turn out! I love foil dinners! XOXO

    The chicken Fajita recipe is excellent and the idea of using the foil is a method I have used many times…Wonderful flavour.. I made the Chicken and Vegetarian versions.

    The Salmon with Lime is also a wonderful dish with a perfect sauce.. I eat salmon a couple of times a week for the Vitamin D.. It is a very moist fish and it is by far my favourite.

    Both recipes are very much keepers and I would not tire of making them.

    Thank you very much
