How to Make Fajitas in the Oven

20-Minute Sheet-Pan Fajitas Will Transform Your Weeknight Dinner Routine

Fact: dinner doesn't get any easier than one-pan meals. And if you're getting insanely bored of the same chicken breast dinner you've eaten 100 times, allow me to introduce you to sheet-pan chicken fajitas, which come together in less than 30 minutes to transform your weeknight routine.

Chop a few vegetables while the oven preheats, grab a pound of chicken from your fridge, use your favorite fajita seasoning mix, and voila! Dinner will be on the table in no time. This recipe is for a basic chicken fajita filling, but you can serve it any way you want. Serve with flour tortillas, over rice, or with your favorite toppings like cheese, sour cream, guacamole, lime juice, or cilantro.
