Step-by-Step Guide to Making Crockpot Chicken Fajitas
Let’s walk through this easy yet rewarding recipe from start to finish.
🔪 Step 1: Prep the Ingredients
Slice the bell peppers and onions into thin, uniform strips to ensure they cook evenly.
If using the homemade seasoning, mix the spices together in a small bowl and set aside.
🥘 Step 2: Assemble in the Crockpot
Start layering your ingredients in the slow cooker:
- Add chicken – Lay it flat at the bottom.
- Sprinkle seasoning – Coat the chicken thoroughly.
- Add vegetables – Peppers and onions go on top to prevent sogginess.
- Add diced tomatoes and broth – Pour evenly.
- Drizzle olive oil and lime juice – Enhances flavor and moisture.
🔥 Step 3: Slow Cook to Tender Perfection
Now the magic begins.
- Low Heat Option: Cook on low for 6–7 hours. Ideal for maximum tenderness.
- High Heat Option: Cook on high for 3–4 hours. Perfect if you’re short on time.
Avoid opening the lid during cooking—moisture and heat retention are essential for flavor and texture.
🍴 Step 4: Shred the Chicken
When done, remove the chicken and shred it using two forks or a hand mixer on low speed. Return it to the crockpot and mix well with the veggies and juices. Let it sit for 10–15 minutes to absorb more flavor.
🌮 Step 5: Warm Tortillas & Serve
How to Warm Tortillas:
- Skillet: 30 seconds per side.
