How To Serve Easy Fajitas:
Whilst this simple fajitas recipe is packed full of flavor, we all know it's the toppings that take this dish to the next level.
This recipe is so versatile you can use whatever you have lurking in the fridge. I like to set everything out in dishes and let everyone make fill their tortilla their own way.
Here are some suggestions to get you started:
- grated cheese
- shredded lettuce
- sliced scallions
- fresh or pickled jalapenos
- lime wedges
- avocado or guacamole
- salsa
- sour cream or yogurt
- hot sauce
- Sour Cream & Chive Dip
Variations of Baked Chicken Fajitas:
- This recipe uses chicken breast, but you can replace that with chicken thighs or legs if you prefer.
- Like chili heat but the kids don't? Simply leave the chili powder out of the mix and instead place some hot sauce or pickled jalapenos on the table so the adults can add to their own wrap.
- To add a little smoky flavor to the fajitas, add a teaspoon of smoked paprika with the other spices.
- Following a low carb diet? No problem. Replace the wraps with a large lettuce leaf for holding the chicken and veggies. Alternatively the meat, veggies and toppings are also great loaded onto a bowl of dressed greens.
- These fajitas are just as good with flour or corn tortillas - your choice!
Tips For Making the best Chicken Fajita Sheet Pan Dish:
- Line the sheet pan with parchment paper to cut down on the washing up and avoid any scrubbing.
- Feeding a crowd - no problem. This recipe can easily be double or quadrupled if necessary. It's so quick and easy you'll have everyone tucking in in no time.
Frequently Asked Questions
Are sheetpan fajitas spicy?
Fajitas don’t have to be spicy at all, which is why they’re so great for families. This recipe uses mild spices like cumin and chili powder for flavour rather than heat. If you’re cooking for kids or prefer things milder, you can reduce or leave out the chili powder. If you like more heat, just add a pinch of cayenne or some sliced fresh chilli.
Can I make sheet pan fajitas ahead of time?
Yes, this is a great make-ahead dinner. You can slice the chicken, peppers, and onions and store them in the fridge for up to a day in advance. When you’re ready to cook, just toss everything with the seasoning and roast. You can also cook everything ahead and reheat—it’s perfect for busy evenings.
Why are my fajitas soggy instead of slightly charred?
This usually happens when the pan is overcrowded. Make sure everything is spread out in a single layer so it roasts instead of steams. Using a hot oven and a large sheet pan also helps get those slightly crispy, caramelised edges.
What is the best protein to use for fajitas?
Chicken is an easy, family-friendly option, but this recipe works with lots of proteins. You can use sliced steak like sirloin, pork tenderloin, or even shrimp. For a lighter option, try salmon or cod. If you want a vegetarian version, extra firm tofu or halloumi both work really well.
Can I use frozen chicken?
It’s best to thaw the chicken first so it cooks evenly and gets those nice roasted edges. If you use frozen chicken straight from the freezer, it will release too much moisture and the fajitas can turn out watery.
Can I make this low carb?
Yes, just skip the tortillas and serve the fajita mixture in a bowl with salad, cauliflower rice, or wrapped in lettuce leaves.
How do I stop the chicken from drying out?
Slice the chicken evenly and don’t overcook it. Cooking at a high heat helps seal in the juices while giving you those slightly charred edges.
Do I need to marinate the chicken?
No, this recipe is designed to be quick and easy, so there’s no long marinating time needed. The seasoning cooks into the chicken as it roasts and still gives plenty of flavour.Storing and Reheating
How To Reheat Baked Chicken Fajitas?
If you need to reheat chicken fajitas, place them in a skillet on the stove over a medium heat until the chicken is hot and warmed through.
However, any leftovers can be served cold and make a great tasting sandwich the next day. They're even better if you have some leftover guacamole and salsa too.
