FAQs
Can I make this recipe on the grill instead of the oven?
Yes, you can cook the foil packets on a grill over medium heat for about 15-20 minutes, turning occasionally, until the steak is cooked to your preference.
What cuts of steak work best for fajitas?
Flank steak, skirt steak, or NY strip are great choices for fajitas because they cook quickly and remain tender when sliced thinly.
