Ingredients List
Here’s what you’ll need to create these delicious sheet pan steak fajitas. Everything is simple and straightforward, so let’s dive in!
- 1 lb Flank steak – Thinly sliced against the grain for maximum tenderness.
- 2 Mixed color bell peppers – Sliced; I love using a mix of red, yellow, and green for that vibrant look!
- 1 large Onion – Sliced; it adds a lovely sweetness when roasted.
For the Seasoning:
- 2 tsp Chili powder – For that warm, spicy kick.
- 1 tsp Cumin – Adds an earthy, aromatic flavor.
- 1 tsp Garlic powder – Because everything’s better with garlic!
- 1 tsp Salt – Enhances all the flavors.
- 1/2 tsp Black pepper – Just the right amount of heat.
How to Prepare Sheet Pan Steak Fajitas
Now that you have your ingredients ready, let’s dive into the simple steps to whip up these mouthwatering sheet pan steak fajitas. You’ll be amazed at how easy it is to create a flavorful dinner!
Step 1: Preheat the Oven
First things first, you’ll want to preheat your oven to 400°F (200°C). Preheating is super important because it ensures that your fajitas cook evenly and get that lovely char on the veggies. Trust me, you’ll want those delicious caramelized edges!
Step 2: Prepare the Ingredients
In a large mixing bowl, combine your thinly sliced flank steak, colorful bell peppers, and onion. Now, it’s time to add the seasoning! Sprinkle the chili powder, cumin, garlic powder, salt, and black pepper over the mixture. I like to use my hands to really get in there and toss everything together until every piece of steak and veggie is coated in those bold spices. This step not only mixes the flavors but also ensures every bite is packed with goodness!
Step 3: Arrange on Sheet Pan
Next, grab your trusty sheet pan and spread the mixture evenly across the surface. Make sure to give everything a bit of space—this will help the steak and veggies roast beautifully rather than steam. You want to see some of that pan! If you crowd the pan too much, you won’t get that nice, roasted finish we’re aiming for.
Step 4: Baking
Pop the sheet pan into your preheated oven and bake for about 20 minutes. I recommend checking around the 15-minute mark to see how things are looking. You want the steak to be cooked to your preference—if you like it medium-rare, just take it out when it’s slightly pink in the center. The veggies should be tender and beautifully caramelized. Oh, the smell wafting from the oven is just heavenly!
Step 5: Serving Suggestions
Once your fajitas are ready, take them out and let them rest for a minute. Serve them up with warm tortillas and don’t forget to add your favorite toppings! I love a drizzle of fresh lime juice, a sprinkle of cilantro, and maybe some creamy avocado or guacamole. The best part is that you can customize these fajitas to your heart’s content, so get creative!

Tips for Success
To make your sheet pan steak fajitas truly fantastic, here are some essential tips that I’ve learned along the way!
- Choosing the Right Steak: Flank steak is my go-to for this recipe because it’s flavorful and tender when sliced correctly. Always slice against the grain for the best texture.
- Veggie Prep: Keep your veggies uniform in size so they cook evenly. I like to slice my bell peppers and onions into strips about 1/4 inch thick for optimal roasting.
- Don’t Skip the Seasoning: Make sure every piece of steak and vegetable is well-coated in the seasoning mix. I find that using my hands works best for an even distribution.
- Resting Time: Let the fajitas rest for a couple of minutes after baking. This allows the juices to redistribute, making every bite juicy and flavorful.
With these tips, you’re sure to impress everyone at the dinner table!

FAQ Section
Can I use chicken instead of steak?
Absolutely! Chicken is a fantastic alternative for these sheet pan steak fajitas. Just use boneless, skinless chicken breasts or thighs, and slice them thinly. The cooking time will be similar, but I recommend checking for doneness around the 15-minute mark. Chicken should be cooked to an internal temperature of 165°F (75°C). You can also add a bit of lime juice or a sprinkle of smoked paprika for extra flavor!
What toppings pair well with sheet pan steak fajitas?
Oh, the toppings can really elevate your fajitas! Here are some of my favorites:
- Guacamole – creamy and delicious!
- Sour cream – adds a nice tang.
- Fresh salsa or pico de gallo – for that fresh burst of flavor.
- Shredded cheese – cheddar or queso fresco both work wonders.
- Chopped fresh cilantro – to brighten everything up.
- Sliced jalapeños – if you like a little heat!
How do I store leftovers?
Storing leftovers is super easy! Just let your fajitas cool down to room temperature, then transfer them to an airtight container. They’ll keep in the fridge for about 3 to 4 days. For reheating, just pop them in the microwave or heat them on the stovetop until warmed through. You can also use a skillet to bring back that delicious char!
Can I make this recipe ahead of time?
You sure can! I love meal prepping with this recipe. You can slice the steak and veggies and toss them with the seasoning a day or two in advance. Just store everything in the fridge until you’re ready to cook. It’s a great way to save time on busy evenings. If you have time, marinating the steak for a few hours or overnight in a mixture of lime juice and spices will give it even more flavor!
What side dishes complement this meal?
To round out your fajita feast, consider serving some delicious side dishes! Here are a few ideas:
- Spanish rice or cilantro lime rice – a perfect pairing!
- Refried beans or black beans – for that extra protein.
- Grilled corn on the cob – sweet and smoky.
- Simple salad with avocado and lime dressing – refreshing!
These sides will really make your meal feel complete and satisfying!
