- 1 can (14 oz) diced tomatoes, drained: Adds acidity and moisture without overwhelming the dish.
- 1/4 cup chicken broth (or water): Helps keep everything juicy and tender during slow cooking.
- 1 tbsp olive oil (optional): Enhances richness and prevents sticking in the crockpot.
- Salt and pepper, to taste: Simple seasonings to balance and heighten the overall flavor.

How to Make Crockpot Chicken Fajitas Recipe
Step 1: Layer the Chicken and Vegetables
Start by placing your chosen chicken breasts or thighs right in the bottom of the crockpot. This creates a juicy base as the chicken slowly cooks, keeping all those delicious flavors close. Next, layer your sliced onions and bell peppers on top; these veggies will soak up the smoky, spicy fajita seasoning as they cook alongside the chicken.
Step 2: Add the Seasoning and Liquids
Sprinkle the fajita seasoning evenly over the chicken and veggies—this blend is truly the heart of the dish’s bold taste profile. Pour the drained diced tomatoes and chicken broth over everything, giving your crockpot a good splash of moisture to keep the chicken tender. If you want an extra touch of richness, drizzle in that olive oil now, too.
Step 3: Slow Cook to Perfection
Cover your crockpot and set it on low for 6 to 7 hours, or on high for 3 to 4 hours if you’re in a hurry. During this slow cooking, the flavors meld beautifully while the chicken becomes fall-apart tender. The aroma alone will have your mouth watering long before dinner time.
Step 4: Shred and Stir
Once the chicken is cooked through, carefully remove it and shred with two forks—this part is so satisfying! Return the shredded chicken to the crockpot and stir it in with the cooked veggies and juices, creating an irresistible saucy mixture.
Step 5: Add the Finishing Touches
Finally, squeeze in fresh lime juice for a burst of tangy brightness that lifts the entire dish. Give everything one more good stir to blend those vibrant flavors together.
How to Serve Crockpot Chicken Fajitas Recipe

Garnishes
The best part of serving fajitas is piling on fresh garnishes that elevate the meal. Fresh chopped cilantro adds a fragrant herbal pop, while a dollop of sour cream or some shredded cheese can bring creamy indulgence. Don’t forget to offer sliced avocado or guacamole for that buttery richness.
Side Dishes
Crockpot Chicken Fajitas Recipe pairs wonderfully with a variety of sides. Spanish rice or cilantro-lime rice keeps things classic, while black beans or refried beans add protein and texture. For a lighter touch, a crisp side salad or some grilled corn on the cob makes a lovely accompaniment.
Creative Ways to Present
Feeling adventurous? Present your fajitas as colorful taco bowls by spooning the chicken mixture over a bed of rice or cauliflower rice. Or try stuffing the filling inside crispy baked tortilla cups for a fun appetizer-style treat. Wrapping them in warm flour or corn tortillas with your favorite toppings makes for a crowd-pleasing hands-on meal everyone will enjoy.
Make Ahead and Storage
Storing Leftovers
Leftover Crockpot Chicken Fajitas store beautifully in an airtight container in the fridge for up to 4 days. Keeping the chicken and veggies stirred together helps the flavors continue to develop, making your next meal just as satisfying as the first.
Freezing
This recipe freezes well, making it a perfect make-ahead meal. Portion into freezer-safe containers and freeze for up to 3 months. When you’re ready to enjoy, thaw overnight in the refrigerator before reheating gently.
Reheating
Reheat your leftovers in a skillet over medium heat or in the microwave until warmed through. Adding a splash of water or broth during reheating helps maintain that wonderful saucy texture and keeps the chicken tender.
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Chicken thighs work wonderfully in this Crockpot Chicken Fajitas Recipe because they tend to stay juicier and more tender after slow cooking.
Is it necessary to drain the diced tomatoes?
Draining the diced tomatoes helps prevent the fajitas from becoming too watery, ensuring a perfect balance of sauce and texture.
Can I make my own fajita seasoning?
Yes, homemade seasoning allows you to control the spice level and ingredients. A mix of chili powder, smoked paprika, cumin, garlic powder, onion powder, salt, and pepper works beautifully.
What type of tortillas work best?
Both flour and corn tortillas are great choices. Flour tortillas tend to be softer and more pliable, while corn tortillas offer a bit more traditional texture and flavor.
Can I cook this on the stove instead of a crockpot?
You can, but the magic of this Crockpot Chicken Fajitas Recipe is in the slow cooking. On the stove, you’d need to cook on low heat for at least an hour to get similar tenderness and flavor melding.
