Let’s Make It Together
- Begin by seasoning the chicken strips generously with salt and pepper—this builds the foundation for flavor.
- Place the seasoned chicken in the slow cooker. Add the sliced bell peppers, onions, and diced tomatoes or salsa, creating a rainbow of ingredients.
- Sprinkle the homemade fajita seasoning over the top, giving it a good stir to ensure everything is coated in goodness.
- If using the Instant Pot, pour in the low-sodium chicken broth for added moisture.
- Cover and cook on HIGH for 2-3 hours or LOW for 4-6 hours, allowing the flavors to meld beautifully. In the Instant Pot, select the poultry setting for about 15 minutes, followed by a natural release.
- Once cooked, enjoy the aroma that fills your kitchen. It’s time to assemble your fajitas!
Variations & Creative Twists
- Add Some Heat: Spice things up with sliced jalapeños or a dash of hot sauce mixed into the fajita filling for those who enjoy a kick!
- Creamy Avocado Sauce: Top your fajitas with a simple avocado cream made by blending ripe avocados, Greek yogurt, lime juice, and a pinch of salt. It’s zesty and indulgent!
- Swap the Protein: Flank steak or shrimp can easily take the stage if chicken isn’t your preference. Just adjust the cooking time accordingly.
- Crisp Toppings: A sprinkle of freshly chopped cilantro, crumbled queso fresco, or crunchy tortilla strips adds a delightful texture.
Chef Emma’s Helpful Tips
- Make-Ahead Convenience: Prepare the fajita seasoning ahead of time and store it in an airtight container for quick weeknight meals.
- Slicing Tips: Freeze the chicken breasts for about 30 minutes before slicing—this makes cutting easier and results in uniform strips.
- Storing Leftovers: Any leftovers can be kept in the fridge in an airtight container for up to 4 days. Reheat gently on the stove or microwave.
- Freezer-Friendly: Portion out extras into freezer bags, and on busy days, simply thaw overnight in the fridge and heat!
