Tips for Easy Slow Cooker Chicken Fajitas

How Do I Prevent My Chicken From Drying Out?

Well, good news. Slow cooker chicken fajitas are foolproof. Cooking chicken in a slow cooker the juices from the chicken and ALL of those veggies in there create a wet heat and you are essentially braising your chicken. The chicken will automatically stay moist when cooked using this method.

An additional tip to keeping your chicken moist is after the chicken is cooked and you have sliced or shredded your chicken, simply return it to the crockpot with the veggies and the perfectly seasoned cooking juices, and voila!

What are the Best Fajita Toppings?

Here is where the real fun begins. First and foremost, toppings for slow cooker chicken fajitas are entirely subjective. It is really all about your personal preference. It should also be noted these fajitas are pretty darn good as is so ultimately no toppings are necessary but let’s talk about some regardless.

Sour cream, guacamole, some shredded cheese. MWAH *chef’s kiss* Don’t have any guacamole or all of the ingredients on hand? Simply slice your avocados and layer on top of your fajita feelings.

A little squeeze of lime will add an additional level of acidity and create a more complex flavor profile one might not expect from just a little fresh juice from the lowly lime. Trust me. Give it a try. You’ll thank me.

Want to take your fajitas to the next level? A little fresh pico de gallo and a spoonful of black beans will hit the spot.

What type of tortilla should you use? Corn? Flour? Traditionally fajitas are served on flour tortillas but this is another place where personal preference comes into play.

Do you want your fajitas on corn tortillas? Go for it! Live! Adamantly opposed to tortillas (or simply dislike them) or also perhaps watching your gluten or carbs? Serve your fajita meat and veggies over a bed of greens and BOOM! you have a chicken fajita salad on your hands! Serve your fajitas over a bed of rice and you have a fajita rice bowl. Nom nom nom. Get crazy. Mix it up.

How Do I Make Beef Fajitas with This Recipe?

Don’t love a chicken fajita? No worries. A few easy modifications and you can use this recipe for shredded beef fajitas.

Simply substitute one and a half pounds of flank steak for the chicken breasts! Season your beef, add the veggies and turn your crockpot to LOW setting and cook for 4-6 hours. Hold off adding your vegetables until half of the way through the cooking process.

If you add your peppers and onions at the start cooking process with the beef they will turn into a mushy mess long before the beef is done. After cooking remove the beef from the crockpot, shred the beef and return to the crockpot with your veggies and all those delicious fajita seasoned juices.

  1. Just made this today for my lunches this week. Unfortunately your statement about the peppers and onion not turning to mush is completely wrong. They did just that. I tried this recipe specifically because I hate overcooked veg and prefer them to be crisp. Maybe adding them at the end if the cooking time, the last 30 mins or so would work better.

    1. Sorry that you did not like. In general, when you use the slow cooker all the ingredients become softer. So you should stir-fry next time if you like it crispier.

  2. This is my 2nd time making this recipe. My family loves these fajitas. Super easy to make and delicious!

  3. Will it make a difference if I use precut chicken breast (chicken tenders) instead of whole? Wanting to try this recipe tomorrow.

    1. I’ve used chicken tenders all the time…. Never had issue with it, tastes just as good. Also I don’t add peppers and onions until last hour or so , I don’t like them soft or mushy… making this for dinner tonight with some refried beans and arroz

  4. Plan to put on for dinner today. I like crisp veggies too, so I’m going to just put the meat in the crockpot and sauté my veggies and then blend with the chicken when ready to serve. Thanks, this recipe sounds like a cinch to make!

  5. I have actually made this recipe a few times. 3 out of 4 of my family members love it. The 1 just doesn’t like anything resembling mexican food. I love this recipe and recommend it!!

  6. 4 hours on high is too long and chicken was quite dry. Skinless, boneless breasts do NOT need to be cooked that long. 3 hours is plenty.

  7. LOVE this recipe! I’ve made it so many times. My husband is a big fan of it. Do you think I could take the peppers out maybe an hour or so before, just so they don’t get too mushy?

  8. Very good ! I knew I wouldn’t have enough time after work to have the slow cooker on high for four hours, so I put it on VERY low for 10 hours. I put the veggies in for about 1.5 hours. I did add about 1 cup of wAyer in with the veggies. It might have ok with only four hours. Either way, it was delicious. I will be making this again.
