Cooking Techniques
Sheet pan cooking makes this recipe super simple! The key to perfect fajitas is cutting your chicken and veggies into similar-sized strips – this helps everything cook evenly. When spreading ingredients on your pan, try not to overlap them too much. This lets them roast instead of steam, giving you those lovely charred edges that make fajitas so tasty!
Easy Substitutions
Feel free to mix up the protein – shrimp works great and cooks even faster! For a vegetarian version, try using portobello mushrooms or extra-firm tofu. Can’t find fresh bell peppers? Frozen pepper strips work in a pinch. You can also swap flour tortillas with corn tortillas for a gluten-free option, or serve everything over rice for a fajita bowl!
Serving Suggestions
Set up a fun fajita bar! Put out bowls of shredded cheese, sour cream, guacamole, and pico de gallo. Add some black beans on the side for extra protein. Want some heat? Offer sliced jalapeños or your favorite hot sauce. A squeeze of fresh lime brightens everything up, while warm tortillas make the perfect wrapper for all these goodies!
Storage Tips
Store leftover chicken and veggies in an airtight container in the fridge – they’ll stay fresh for up to 3 days. Keep tortillas separate to prevent them from getting soggy. When reheating, a quick zap in the microwave works, but for better results, try a hot skillet to bring back some of that crispy texture. The fajita seasoning mix can be made ahead and stored in a sealed jar for up to 3 months!
