What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most items are pantry staples or easy to find at any grocery store. If you’ve got steak, peppers, and a few spices, you’re already halfway there!

• For the Fajitas:
  • 1.5 pounds (680g) flank steak or skirt steak, thinly sliced (choose well-marbled for juiciness)
  • 3 medium bell peppers (any colors), sliced into strips (red, yellow, and green add extra visual pop)
  • 1 large red onion, sliced into strips
• For the Marinade:
  • 3 tablespoons (45ml) olive oil (helps everything roast evenly and adds richness)
  • 2 tablespoons (30ml) lime juice (freshly squeezed for zing)
  • 2 teaspoons chili powder
  • 1 teaspoon smoked paprika (regular works too, but smoked adds depth)
  • 1 teaspoon ground cumin
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt (or more, to taste)
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon crushed red pepper flakes (optional, for heat)
• For Serving:
  • 8-10 flour tortillas (or corn tortillas for gluten-free)
  • Sour cream, guacamole, shredded cheese, fresh cilantro, salsa (optional toppings)
  • Extra lime wedges for squeezing

Ingredient tips: If you want a leaner option, swap the steak for boneless chicken thighs or portobello mushrooms. Need it dairy-free? Skip the cheese and sour cream. For extra color, toss in sliced poblano or jalapeño peppers. I’m partial to Mission brand tortillas for fluffiness, and I always choose a fresh, firm steak from the butcher for best results. If you’re cooking for a crowd, you can easily double everything—just use two sheet pans!

Sometimes I toss a few cherry tomatoes on the pan for added sweetness, especially in summer. If you don’t have smoked paprika, regular will do—I’ve tried both, and the results are always tasty. The marinade is flexible, so feel free to play around with spice levels or swap lime for lemon in a pinch. It’s all about making these sheet pan fajitas with steak and peppers your own!

Equipment Needed

One of my favorite things about sheet pan fajitas with steak and peppers is you really don’t need much gear. Here’s what I use every time:

• Large rimmed sheet pan (about 18×13 inches / 46x33cm) — essential for spreading everything out in a single layer
• Sharp chef’s knife — for slicing steak and veggies thinly (makes all the difference)
• Cutting board — a sturdy one for prepping all your ingredients
• Mixing bowl — for tossing everything with the marinade
• Tongs or spatula — for transferring and flipping ingredients
• Measuring spoons — to get those spices just right
• Aluminum foil or parchment paper (optional, for easier cleanup)

If you don’t have a big sheet pan, you can use two smaller ones—just rotate them halfway through cooking. I’ve tried using a silicone baking mat for easier clean-up, and it works well, but sometimes you miss out on that slightly crispy edge. A good, sharp knife is worth its weight in gold for slicing steak thin enough to cook quickly (learned that the hard way with a dull one!). For budget-friendly options, I’ve picked up basic measuring spoons and mixing bowls at the dollar store, and they hold up just fine.

Maintenance tip: If you use a nonstick pan, avoid metal spatulas—they’ll scratch it up. I stick with silicone or wood. Honestly, this is one recipe where fancy gadgets aren’t needed—just good basics and a trusty oven.

Preparation Method

Ready to make sheet pan fajitas with steak and peppers? Here’s how I do it, step by step:

1. Preheat the oven. Set your oven to 425°F (220°C). You want it hot for caramelization. Line your sheet pan with foil or parchment if you like easy cleanup.
2. Slice the steak and veggies. Cut the steak into thin strips, about 1/4 inch (0.6cm) thick. Slice bell peppers and onion into similar-size strips. (Thin slices cook fast and evenly!)
3. Mix the marinade. In a large bowl, whisk together 3 tablespoons (45ml) olive oil, 2 tablespoons (30ml) lime juice, 2 teaspoons chili powder, 1 teaspoon smoked paprika, 1 teaspoon cumin, 1 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1/4 teaspoon crushed red pepper flakes (if using).
4. Toss everything in the marinade. Add steak, peppers, and onions to the bowl. Toss well until everything is evenly coated. Let it sit for 5-10 minutes while the oven heats—this helps the flavors soak in (don’t skip!).
5. Spread on the sheet pan. Arrange the steak and veggies in a single, even layer. If you’re doubling the recipe, use two pans. Spread everything out so it roasts, not steams.
6. Roast. Place sheet pan in the oven and cook for 15-18 minutes. If you want a little char, switch to broil for the last 2-3 minutes (watch closely!). The steak should be sizzling and the veggies tender with caramelized edges.
7. Warm the tortillas. While the fajitas cook, wrap tortillas in foil and pop them in the oven for 5 minutes. Or heat them in a dry skillet until just warm and pliable.
8. Check doneness. Steak should be cooked to your liking—medium-rare is about 135°F (57°C) internal temp, but you can go up to 145°F (63°C) for medium. Veggies should be soft but still have a little bite.
9. Serve. Transfer steak and peppers to a platter. Squeeze fresh lime juice over the top and sprinkle with chopped cilantro, if desired.
10. Build your fajitas. Let everyone grab a tortilla and pile on their favorite fillings—sour cream, cheese, salsa, guacamole.

Troubleshooting tips: If your steak releases a lot of liquid, drain off excess halfway through roasting. If veggies aren’t browning, spread them out more. For crispier edges, broil for a minute at the end—but don’t wander off, as broilers can go from perfect to burnt in seconds (trust me, I’ve learned).

Personal tip: I prep everything ahead and stash it in the fridge. When it’s dinnertime, just toss, roast, and serve. Cleanup is a breeze, and everyone feels like they’re getting a restaurant meal at home. Sheet pan fajitas with steak and peppers—easy, flavorful, and always a win!

Cooking Tips & Techniques

Sheet pan fajitas with steak and peppers are pretty forgiving, but here are some tricks I’ve picked up over time (mostly through trial and error):

• Slice steak thinly and against the grain. This keeps it tender—even if you accidentally cook it a bit longer than planned.
• Spread in a single layer. Crowding the pan means veggies will steam, not roast. Use two pans if you have lots of ingredients.
• Don’t skip the marinade. Even 10 minutes gives steak and veggies more flavor. I’ve rushed it before, and it’s just not the same!
• Watch the broiler. A quick broil at the end gives everything a charred finish, but keep an eye out. I’ve burned a batch before—lesson learned.
• Rest the steak before serving. Just 2-3 minutes on the pan lets juices redistribute, so every bite is juicy.

If you’re multitasking, prep toppings while the sheet pan is in the oven. It saves time and makes dinner feel special. I sometimes cook an extra batch of peppers on a second pan for leftovers—they’re great in omelets or salads. For consistent results, always preheat your oven fully. Cold oven = uneven cooking (I’ve tried to rush it, and regretted it!).

Common mistakes? Overcooking steak (it gets tough fast), slicing veggies too thick (they stay crunchy), and forgetting to shake the pan halfway through for even roasting. Sheet pan fajitas with steak and peppers are all about the details—small tweaks make a big difference. My best advice? Trust your senses—look for caramelized edges, smell the spices, and listen for that satisfying sizzle when it comes out of the oven.

Variations & Adaptations

Sheet pan fajitas with steak and peppers are endlessly adaptable. You know, sometimes I get creative just to keep things interesting—here are a few favorite twists:

• Chicken or Shrimp Swap: Use boneless skinless chicken breasts or thighs instead of steak. Shrimp works too—just add them for the last 8 minutes of cooking so they don’t overcook.
• Vegetarian Version: Substitute steak with thick-sliced portobello mushrooms or tofu strips. Toss with the same marinade and roast until golden.
• Low-Carb/Keto: Skip the tortillas and serve fajitas over a bed of cauliflower rice or lettuce wraps. Still delicious, with fewer carbs!
• Spicy Fajitas: Add sliced jalapeños or a sprinkle of chipotle powder in the marinade. I’ve tried this for heat lovers, and it’s a hit.
• Seasonal Veggies: Toss in zucchini, cherry tomatoes, or even asparagus when in season. The more color, the better it looks (and tastes) on your plate.
• Different Cooking Methods: If you’re grilling, thread steak and veggies onto skewers and cook over medium-high heat. Or, try an air fryer for small batches—just shake halfway through.
• Allergen Substitutions: Use gluten-free tortillas or dairy-free toppings. You can even make it nut-free by sticking to classic ingredients.

My personal favorite adaptation? I sometimes add a sprinkle of smoked sea salt before serving, just for extra oomph. If you love cilantro, chop it fresh and shower it over everything. It’s all about making the recipe fit your taste and needs. Sheet pan fajitas with steak and peppers are the ultimate canvas—make them yours!

Serving & Storage Suggestions

Sheet pan fajitas with steak and peppers are best served hot, right off the oven. I like to pile everything onto a big platter, sprinkle with fresh cilantro, and let folks build their own fajitas at the table. Warm tortillas (wrapped in a cloth or foil) keep things cozy. For a Pinterest-worthy presentation, layer the steak and peppers in rainbow stripes and add lime wedges for pop.

Pair these fajitas with Spanish rice, refried beans, or a crunchy slaw. A pitcher of fresh limeade or homemade margaritas rounds out the meal perfectly. Sometimes, I toss in a bowl of pico de gallo or sliced avocado—always a hit!

Storing leftovers: Cool everything, then stash in airtight containers. Steak and veggies keep well in the fridge for up to 3 days. For freezing, portion into zip-top bags and freeze up to 2 months. (Thaw overnight in the fridge before reheating.)

Reheating tips: Spread leftovers on a sheet pan and warm in a 350°F (175°C) oven for 10 minutes. Or, microwave in 30-second bursts, stirring between each. The flavor actually deepens as it sits—so tomorrow’s lunch might be even tastier!

If you’re prepping for meal planning, double the batch and enjoy easy fajita bowls all week. Sheet pan fajitas with steak and peppers are perfect for lunchboxes—just pack tortillas on the side so they stay fresh.
