Ingredients
Scale
Proteins:
- 1 pound (454 grams) flank steak
Vegetables:
- 1 yellow onion, sliced
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- 1 yellow bell pepper, sliced
Seasonings and Liquids:
- 3 tablespoons fajita seasoning
- 1/4 cup (60 milliliters) olive oil
- 1 tablespoon (15 milliliters) lime juice
- Salt to taste
- Black pepper to taste
Serving Accompaniments:
- Small flour tortillas
- Small corn tortillas
- Limes
- Cilantro
- 1 avocado (optional)
Instructions
- Prepare the oven at 400F (200C) and line a baking sheet with aluminum foil for easy cleanup and efficient cooking.
- Cut the flank steak into thin, uniform 1/2-inch strips to ensure even cooking and tender texture.
- Create a zesty marinade by whisking olive oil, fajita seasoning, and fresh lime juice in a mixing bowl.
- Transfer the steak strips into a resealable plastic bag, pour the marinade over, and let it infuse flavors for 10-15 minutes.
- Slice bell peppers and onions into similar-sized strips to promote consistent roasting and visual appeal.
- Toss the vegetable slices with remaining olive oil, additional fajita seasoning, salt, and pepper for enhanced flavor.
- Arrange vegetables on the prepared sheet pan, creating space for steak strips to ensure proper caramelization.
- Position marinated steak strips alongside the vegetables, maintaining some separation for even roasting.
- Roast in the preheated oven for 12-15 minutes, rotating and flipping ingredients midway to promote uniform cooking.
- Simultaneously warm tortillas and prepare garnishes like fresh cilantro and lime wedges.
- Remove sheet pan when steak reaches desired doneness and vegetables are tender and slightly charred.
- Allow fajitas to rest briefly, then serve immediately with warm tortillas, optional avocado, and fresh garnishes.
Notes
- Marinate the steak for extra flavor by letting it sit in the seasoning for at least 30 minutes before cooking, or even overnight in the refrigerator for deeper taste infusion.
- Use a meat thermometer to check the steak’s doneness, aiming for medium-rare at 135°F (57°C) for the most tender and juicy results.
- For a gluten-free version, swap regular flour tortillas with corn tortillas or lettuce wraps to accommodate dietary restrictions.
- Customize the heat level by adjusting the amount of fajita seasoning or adding hot sauce for those who love a spicy kick.
