How to Make Sheet Pan Steak Fajitas Recipe
Step 1: Preheat and Prepare Your Pan
Start by heating your oven to 400 degrees Fahrenheit. While it’s warming up, drizzle your extra virgin olive oil across a large baking sheet. This oil base is essential for preventing sticking and helping your steak and veggies roast to perfection with a slight crisp.
Step 2: Slice Your Ingredients
Thinly slicing the sirloin steak and all your vegetables ensures everything cooks evenly and in a similar timeframe. This creates the ideal balance between tender steak strips and softly charred, sweet peppers and onions.
Step 3: Season and Toss
Sprinkle the taco seasoning, smoked paprika, soy sauce, and fresh lime juice evenly over your sliced meat and veggies. Getting hands dirty here is worth it — toss everything gently on the baking sheet, making sure all those layers of flavor coat the ingredients well. Spread the mixture out in an even layer so everything cooks uniformly.
Step 4: Roast to Perfection
Place the sheet pan in your preheated oven and roast for 10 to 13 minutes, depending on how you like your steak cooked. The vegetables should be tender and carrying a gorgeous golden-brown edge, while the steak remains juicy and packed with those bold, smoky spice notes.
Step 5: Serve and Enjoy
Once out of the oven, it’s time to assemble your fajitas. Load warm tortillas with the steak and veggie medley, and top with your favorite add-ons like sour cream, shredded cheese, or fresh salsa. Don’t forget a sprinkle of fresh cilantro to brighten the dish even more.
How to Serve Sheet Pan Steak Fajitas Recipe

Garnishes
Fresh cilantro is the classic finish, adding an herbal punch that makes the colors pop and the flavors sing. A squeeze of lime over the top can also elevate the fajitas before serving.
Side Dishes
Simple sides like Mexican rice, black beans, or a crisp green salad are perfect partners, rounding out the meal without overwhelming the star ingredient—the Sheet Pan Steak Fajitas Recipe. For something different, try serving with grilled corn or a light avocado salad.
Creative Ways to Present
Think beyond the classic tortilla fold. Stuff the fajita filling into colorful taco shells or even spoon it over a bed of warm quinoa or cauliflower rice for a fun twist. For a party, serve it family-style with all the fillings in bowls and everyone building their own.
Make Ahead and Storage
Storing Leftovers
Leftover fajitas keep beautifully in an airtight container in the refrigerator for up to 3 days. Store the steak and veggies separately from tortillas to prevent them from getting soggy.
Freezing
If you want to plan ahead, freeze the cooked steak and vegetables in freezer-safe containers or bags for up to 2 months. Thaw in the refrigerator overnight before reheating.
Reheating
Reheat by spreading the fajita mixture on a baking sheet and warming in a 350-degree oven for 8-10 minutes. This method keeps the veggies tender but slightly crisp, and the steak juicy. Microwaving works too but can make the veggies a bit soft.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While sirloin is tender and perfect for quick cooking, flank or skirt steak also work well for fajitas due to their flavor and texture when sliced thin.
What if I don’t have taco seasoning on hand?
You can easily mix your own by combining chili powder, cumin, garlic powder, onion powder, paprika, and a pinch of cayenne pepper to taste. It’s fresher and customizable!
Can I make this recipe gluten-free?
Yes! The steak fajitas are naturally gluten-free if you use gluten-free soy sauce or tamari and check that your taco seasoning doesn’t contain gluten.
Is it possible to make this in an air fryer instead of the oven?
Definitely! Cook the steak and vegetables at 400 degrees in the air fryer for about 10 minutes, shaking the basket halfway through, for a quick and tasty alternative.
How spicy is this Sheet Pan Steak Fajitas Recipe?
The heat level depends on your taco seasoning—usually moderate. You can adjust it by adding jalapeños or extra chili powder if you like more kick, or omit spicy ingredients for a milder dish.
