This 4-ingredient slow cooker Cinco de Mayo chicken is exactly the kind of weeknight dinner I lean on when work runs late but I still want something fun and a little festive. You literally toss raw chicken fajita strips into the crock pot, add just three pantry-friendly ingredients, and let it do its thing. By the time you’re ready to eat, you’ve got tender, zesty, pull-apart chicken that tastes like it took way more effort than it actually did—perfect for tacos, rice bowls, or nachos when friends come over for a casual Cinco de Mayo get-together.
Serve this Cinco de Mayo chicken tucked into warm flour or corn tortillas with shredded lettuce, cheese, salsa, and a squeeze of lime. It’s also great spooned over cilantro-lime rice or Spanish rice with a side of black beans or refried beans. For a party spread, set out a build-your-own taco or nacho bar with tortilla chips, guacamole, pico de gallo, sour cream, and sliced jalapeños. A simple side salad with romaine, corn, and avocado rounds everything out, and a pitcher of sparkling lime water or margaritas (if you’re celebrating) fits the theme perfectly.
4-Ingredient Slow Cooker Cinco de Mayo Chicken
Servings: 6
Ingredients
2 pounds raw chicken fajita strips (pre-cut, unbreaded)
1 (16-ounce) jar thick and chunky salsa (mild, medium, or hot)
1 (1-ounce) packet taco seasoning (about 2 tablespoons)
1 cup low-sodium chicken broth
Directions
Place the raw chicken fajita strips in an even layer on the bottom of a 5- to 6-quart slow cooker. This should look like a close-up top-down shot of raw strips covering the base of the crock.
Sprinkle the taco seasoning evenly over the chicken fajita strips so they’re lightly coated with the spices.
Pour the jar of salsa over the seasoned chicken, spreading it out a bit with a spoon so most of the chicken is covered.
Pour the chicken broth around and over the salsa-covered chicken. Do not stir; just let the liquid settle into the bottom and around the sides so the chicken stays mostly in place.
Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or on HIGH for 2 to 3 hours, until the chicken fajita strips are cooked through and very tender (internal temperature should reach at least 165°F/74°C).
Once cooked, use two forks to shred the chicken directly in the slow cooker, mixing it well with the salsa and cooking juices until everything is evenly combined and saucy.
Taste and adjust seasoning if needed (you can add a pinch of salt or more taco seasoning if you like a stronger flavor). Switch the slow cooker to WARM and let the chicken sit for 10 to 15 minutes to absorb more of the sauce before serving.
Serve the Cinco de Mayo chicken hot in tortillas, over rice, or on top of tortilla chips with your favorite toppings.
Variations & Tips
For a creamier version, stir in 4 ounces of softened cream cheese or 1/2 cup sour cream after shredding the chicken, then let it melt on WARM for about 10 minutes before serving. If you like more veggies, you can add 1 sliced bell pepper and 1/2 sliced onion on top of the raw chicken fajita strips before adding the salsa and broth (this keeps the ingredient list simple while still feeling like fajitas). To make it spicier, use hot salsa and add a chopped jalapeño or a pinch of crushed red pepper flakes before cooking. For a lighter option, choose a fresh-style salsa with no added sugar and use low-sodium taco seasoning and broth. Leftovers make great meal prep: store cooled chicken in an airtight container in the fridge for up to 4 days or freeze for up to 3 months, then reheat gently on the stove or in the microwave with a splash of broth if it seems dry. Food safety tips: always start with fully thawed raw chicken fajita strips (never frozen solid) so they reach a safe temperature quickly and evenly in the slow cooker. Avoid lifting the lid during cooking, as this can lower the temperature and increase cook time. Use a meat thermometer to ensure the chicken reaches at least 165°F/74°C in the thickest pieces. Refrigerate leftovers within 2 hours of cooking, and when reheating, bring them back to 165°F/74°C before serving.
