Ingredients
Sheet Pan Flank Steak Fajitas combines just a handful of fresh ingredients with pantry staples you probably already have in your spice cabinet.
- Flank Steak - This lean but beefy cut of beef comes from the flank, or rear of the cow near the plate. It's at it's most tender when it's cooked medium-rare to medium and thinly sliced.
- Bell Peppers - Red and yellow bell peppers add color and are sweeter than the green variety.
- Red Onion - Red onions caramelize and become sweet as they roast.
- Kosher Salt - Salt seasons both the vegetables in this sheet pan meal as well as the steak.
- Black Pepper - Adds earthy heat to the marinade.
- Cumin - Aromatic, earthy, and a little citrusy.
- Paprika - Not only adds a slight sweetness to the marinade, it also helps the flank steak develop a crust as it roasts.
- Garlic Powder - Bright, sharp, and pungent, this adds aromatic and savory flavor to the marinade.
- Onion Powder - Sweeter than garlic powder, onion powder offers up a fragrant savory note.
- Chili Powder - This adds mellow, earthy heat. Use your favorite variety such as ancho or guajillo.
- Olive Oil - Helps bring the marinade together as well as roast the steak and vegetables.
- Lime - Not only adds bright flavor to the marinade, the acid in lime juice also helps tenderize the flank steak.
