Karlynn’s Recipe Notes
- Skill Level: Beginner-friendly and totally foolproof! If you can slice a few veggies, you’re golden – the slow cooker does it all for you.
- Total Time: About 4-6 hours – most of that’s just your slow cooker doing the work while you go live your life!
- Variations: Add in different veggies, like mushrooms or corn or black beans for added texture! Also – try serving your fajitas with our easy chunky guacamole – or, try our avocado crema as a topping – and of course, lots of shredded cheese!
- Spice it up: Love your spice? Toss in a diced jalepeno or pinch of chilli flakes for an awesome kick.
- Tools You’ll Need: The key tool here is a slow cooker – it’ll be your cheat code to success! A 5-6 quart slow cooker is perfect. You also want to keep some tongs handy!
- Prep Friendly: you can prep all the ingredients the night before and store them in the frige – just dump everyting into the slow cooker in the morning. Dinner will be ready right when you walk in the door!

What You’ll Need for Ingredients
Chicken: Boneless, skinless chicken breasts are the go-to here – they shred beautifully after a few hours in the slow cooker. Karlynn’s Tip: I pesonally love using boneless chicken thighs as well, especially if you like things a little juicier!
Peppers & Onions: A mix of red, yellow, and green bell peppers adds color and sweetness, while sliced onion gives that classic fajita flavor. Don’t stress too much about the combo – use whatever’s in your fridge! Karlynn’s Tip: Add in whatever veggies you like, like mushrooms or corn!
Seasoning: A packet of fajita seasoning keeps things simple, but if you’ve got a favorite homemade blend, go for it. A touch of chili powder or smoked paprika can also kick it up a notch.
Extras: A drizzle of olive oil helps the seasoning stick, and a squeeze of lime at the end brightens the whole dish up – and of course, you can’t forget the shredded cheese! Karlynn’s Tip: Don’t forget your tortillas – or swap them for rice or salad greens if you’re going low-carb!

How To Make Crockpot Chicken Fajitas
This is a quick overview of the recipe. The full list of ingredients & complete step-by-step instructions are in the recipe card below.




- Place the chicken in your crockpot.
- Sautee your onions until brown and place ontop of the chicken.
- Combine salsa, seasoning mix, lime juice & sugar and pour into crockpot.
- Cook on high for 4 hours, or low for 6-8 hours – set it and forget it!
- Serve on tortillas and garnish however you like. Enjoy!


Storage Instructions
Refrigerator: Store leftovers in an airtight container for up to 4 days. The flavors actually get even better after a day or two – perfect for easy lunches! Just reheat gently in a skillet or microwave until warmed through.
Freezer: Cool completely, then portion into freezer-safe bags or containers (juice and all). You can freeze this safely for up to 3 months! Thaw overnight in the fridge, then reheat on the stove or in the microwave.
Pro Tip: If you are planning to freeze, skip adding fresh toppings like lime or cilantro until after reheating – it’ll taste much fresher that way.

This meal is simple, very flavourful and absolutely delish! The only change I made was eliminating the lime juice, only because I didn’t have any, but honestly it was the best thing I’ve made in my kitchen in a long time. Thank you, Karlyn!
