This Latin-Style Sheet Pan Steak Fajitas recipe is a bold, speedy dinner that packs a whopping 50g of protein in a single serving. High-heat roasting caramelizes the onions and sweetens the peppers while keeping them tender-crisp. The flank steak stays juicy, infused with smoky, citrusy, and savory notes thanks to a vibrant spice-lime marinade. Serve with creamy guacamole and fresh cilantro for a burst of color and flavor. It’s a fiesta on a sheet pan—perfect for a hassle-free, protein-rich meal any night of the week.
Ingredients
Instructions
Preheat your oven to 450°F (232°C). Line a sheet pan with parchment or foil for easy cleanup.
In a large bowl, toss the flank steak strips with lime juice, olive oil, cumin, chili powder, smoked paprika, garlic powder, salt, and black pepper until evenly coated.
Add the sliced bell pepper and red onion to the bowl and gently toss again to coat the vegetables in the marinade.
Spread the steak and veggies in a single layer on the prepared sheet pan.
Roast in the hot oven for 10-12 minutes, tossing halfway, until the steak is just cooked through and the peppers are tender-crisp with some charred edges.
Meanwhile, warm the tortillas and prep the guacamole and cilantro.
Remove the sheet pan from the oven. Assemble fajitas by piling steak and veggies into warm tortillas. Top each with a dollop of guacamole, fresh cilantro, and a squeeze of lime.
Serve immediately with extra lime wedges on the side.
