I’ve made these sheet pan steak fajitas so many times, they’ve basically become a staple recipe at home.

The steak always turns out tender, the peppers keep a nice bit of crunch, and that fresh squeeze of lime at the end really brings together all the flavors.

Just pile everything into warm tortillas, toss on your favorite toppings, and you’ve got a meal everyone can make their own.

If you ask me, this is one of those recipes you’ll want to keep in your back pocket for whenever you need something fast, tasty, and satisfying!

Tips and Tricks!

I’ve made these sheet pan fajitas so many times over the years. Along the way, I’ve picked up a handful of tips that just might help you out:

  • Steak Doneness: 20-minute bake at 400°F gives me a lovely medium-rare steak. Sometimes, though, my family wants it a bit more done, so I tack on another 2-3 minutes. The trick is to tap into your own preferences when deciding on timing.
  • My Storage Solution: When I make extra, I stash leftovers in glass containers. They stay fresh in the fridge for 2-3 days—honestly, the flavors seem even better by day two!
  • Personalize It: I love tossing on crumbled queso fresco and a handful of cilantro. My kids are all about that big scoop of sour cream. I recommend doing what feels best for you.
  • Meal Prep: On hectic weeknights, this recipe has saved me countless times. Sometimes I prep the marinade and slice everything the night before, so I just have to throw it all together and bake when I get home.
  • Tortilla Tip: I wrap my tortillas in foil and toss them in the oven for the last 5-10 minutes. They warm up perfectly—no dry edges.
  • My Slicing Recommendation: Always slice against the grain. It really does make the steak way more tender.
  • Sheet Pan Tip: I never overcrowd my pan. If I’m doubling the recipe, I just grab a second pan instead of piling everything into one.
