Ingredients
- Flank Steak: Choose a fresh, well-marbled flank steak for the juiciest results. Slice thinly across the grain to keep the meat tender and cook it quickly in the oven.
- Bell Peppers: Use a mix of colors, such as red, yellow, and green, for added appeal and flavor.
- Yellow Onion: Adds sweetness and depth to the fajitas. Slice thinly so it cooks evenly alongside the steak and peppers.
- Homemade Fajita Seasoning: A combination of chili powder, paprika, cumin, onion powder, garlic powder, dried oregano, cayenne pepper, salt, black pepper, and a touch of sugar. This blend gives your steak fajitas a bold, smoky, and slightly spicy flavor. Try our French fry seasoning for another homemade spice blend recipe.
- Cilantro and Lime: Fresh cilantro adds a bright, herbal note, and lime juice provides acidity to balance the richness of the steak and seasonings.

- Southwest Style: Add black beans and corn to the sheet pan before baking for a hearty, southwestern-inspired twist.
How to Cook Beef Fajitas in the Oven
These steak fajitas in the oven are quick, easy, and full of flavor. To get started, preheat the oven to 400℉ and lightly spray a sheet pan with nonstick cooking spray so everything cooks evenly and nothing sticks.
- Step 1: Prepare the Seasoning. Mix the chili powder, paprika, cumin, onion powder, garlic powder, oregano, cayenne, salt, black pepper, and sugar in a small bowl until well combined. This will be the flavorful coating for the steak and vegetables.
- Step 2: Arrange the Vegetables and Steak. Spread the sliced bell peppers and onion on the prepared sheet pan, then place the thinly sliced flank steak on top. Sprinkle the seasoning over everything and drizzle with olive oil and minced garlic, tossing gently to coat.
- Step 3: Bake in the Oven. Place the sheet pan in the preheated oven and bake for 18 to 25 minutes, until the steak reaches an internal temperature of 145℉ and the vegetables are tender. Serve with your favorite toppings and layered taco dip or smoked queso dip to start!
Expert Tips
- Slice Steak Thinly: Cutting the flank steak thinly across the grain ensures it cooks quickly and stays tender. Thicker slices can become chewy and unevenly cooked.
- Even Vegetable Cuts: Slice the peppers and onions evenly so everything cooks at the same rate and you avoid some pieces being overdone while others are undercooked.
- Don't Overcrowd the Sheet Pan: Give the steak and vegetables some space to roast properly; crowded pans can steam the ingredients instead of roasting them.
- Warm Tortillas Properly: Wrap tortillas in foil and warm them in the oven during the last 5 minutes of cooking to keep them soft and pliable, preventing cracking or tearing when wrapping your fajitas.
- Storage and Reheating. Store leftover fajitas in an airtight container in the fridge for up to 3-4 days. Reheat gently in the oven at 325℉ or in a skillet to maintain texture and flavor instead of microwaving.
Serving Suggestions
- Serve these sheet pan steak fajitas for a quick weeknight dinner, pair them with some Mexican rice, and finish the meal with our easy key lime pie.
- Great for parties or potlucks, set up a fajita bar with tortillas, fresh pico de gallo or restaurant salsa at home, and other easy toppings like shredded cheese, sour cream, and avocado slices.
Recipe FAQs
Slice the flank steak thinly across the grain and bake just until it reaches 145℉. Let it rest for a few minutes after cooking to keep it juicy and tender.
Yes, store cooked steak and vegetables in an airtight container or freezer bag for up to 2 months. Thaw in the fridge overnight and reheat in a skillet or oven before serving.
Yes! You can prep everything ahead. Slice the steak and veggies, toss them with the fajita seasoning and oil, then store them separately in an airtight container for up to 24 hours. When ready to cook, just spread everything out on the sheet pan and roast as directed. If you want to go even further, you can fully bake them, cool, and reheat just before serving, but prepping fresh and baking right before dinner gives you the best texture and flavor.
The trick is gentle heat. Reheat the fajitas in a skillet over medium-low heat with a splash of water or lime juice. Make sure to add just enough to steam and re-moisten the steak and veggies. You can also cover the skillet for a minute or two to help lock in moisture. If you're using the oven, spread the fajitas out on a sheet pan, cover loosely with foil, and warm at 325°F until heated through. Avoid microwaving as the steak can turn tough and rubbery.
