How to Make Easy Sheet Pan Steak Fajitas
Preheat your oven to 400°F (200°C) while you prep your ingredients. Line a large baking sheet with parchment paper for easy clean-up later.
Marinate the Steak: In a bowl, combine olive oil and taco seasoning. Add thinly sliced flank steak and toss well until fully coated. Let it marinate for at least 15 minutes to absorb all those spices.
Prepare the Veggies: While the steak marinates, slice your bell peppers and onions into thin strips. Their vibrant colors will brighten up your dish while adding crunch.
Arrange on the Sheet Pan: Spread the marinated steak evenly across one side of the baking sheet; arrange bell peppers and onions on the other side. Drizzle a little olive oil over the vegetables for extra flavor.
Bake to Perfection: Place the baking sheet in the oven and bake for about 20-25 minutes until veggies are tender and steak reaches desired doneness. Keep an eye out as those peppers start caramelizing!
Toss and Serve: Once baked, remove from oven and give everything a good toss. Serve hot with warm tortillas on the side—don’t forget your favorite toppings like guacamole or salsa!
