Serving Suggestions

One of the best things about crock pot chicken fajitas is how versatile they can be! For instance, we paired them with white rice. However you could also use it as stuffing for tortillas, placed on top of  greens for a salad, loaded onto tortilla chips for nachos, or even added to eggs to create an omelet! For even more flavor, try adding beans, sour cream, and shredded cheese to finish off whatever you choose to serve.

Storage and Meal Prep

We like to make a big batch of crock pot chicken fajitas to eat throughout the week. Luckily, they store super well. Just be sure to place them in an airtight container, and keep them in the fridge for up to 3-4 days.

Or, place leftovers in the freezer for up to 9 months. Then, when you’re ready to eat, thaw them in the fridge overnight.

How to Reheat

When you’re ready to eat, add your fajita mixture to a baking dish, cover it with foil, and let it heat in the oven for about 30 minutes at 365° Fahrenheit. Or, add it to a skillet over medium heat until heated through. If you must, you can warm them in the microwave as well, but this method may result in dry chicken.

Is it Better to Cook on Low or High Heat?

For the best results, we recommend cooking your chicken on a low heat setting. This helps keep it extra moist and juicy.

However, the high setting works, too if you’re in a bit of a pinch for time! Just be sure not to forget about it as leaving it in the crock pot for longer than 2 hours will likely cause it to become a bit dry.

Do I Have to Use Chicken?

Not at all! We prefer chicken because it’s super easy, affordable, and usually satisfies everyone. However, this recipe should work with any meat you’d like to substitute such as steak or shrimp. Just note that the cooking times will likely vary.

Can I Use Frozen Vegetables?

Yes! If you want to save time, you can usually even find pre-sliced onions and peppers in the frozen section of your local grocery store. Just keep in mind that your fajita mixture may be slightly more watery than if you used fresh vegetables.
