Tips for Perfect Slow Cooker Chicken Fajitas
- Don’t Overcook: Overcooked chicken can become dry. Check the chicken periodically towards the end of the cooking time.
- Adjust Spice Level: Control the heat by adjusting the amount of cayenne pepper in your homemade seasoning, or by adding (or omitting) the jalapeño.
- Sear the Chicken (Optional): For added flavor, sear the chicken breasts in a skillet before adding them to the slow cooker. This adds a nice caramelized crust.
- Use Different Vegetables: Feel free to add other vegetables like mushrooms, corn, or poblano peppers.
- Thicken the Sauce (Optional): If the sauce is too thin for your liking, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir it into the slow cooker during the last 30 minutes of cooking.
- Warm the Tortillas: Warm tortillas are essential for the best fajita experience. You can warm them in a dry skillet, microwave, or oven.
- Let Rest: Allow the chicken to rest for 10 minutes after cooking before shredding; this helps retain its moisture.
