What Are Steak Fajitas?
Steak fajitas are a classic Tex-Mex dish made with seasoned, grilled or seared strips of steak, sautéed peppers, and onions. Traditionally served on a sizzling platter with warm tortillas and optional toppings like guacamole, salsa, sour cream, or shredded cheese, steak fajitas are flavorful, festive, and endlessly customizable.
The word “fajita” comes from the Spanish word faja, meaning “belt” or “strip.” It originally referred to skirt steak cut into strips, but modern recipes use a variety of beef cuts to suit different preferences.
Best Cut of Beef for Steak Fajitas
The secret to the best steak fajitas lies in choosing the right cut of meat. Here are the top three cuts to consider:
1. Skirt Steak (Traditional Choice)
- Known for its rich beefy flavor
- Thin and long, perfect for quick cooking
- Must be sliced against the grain to avoid toughness
2. Flank Steak
- Lean and flavorful
- Slightly thicker than skirt steak, but still works great
- Requires marinating for maximum tenderness
3. Sirloin Steak
- A bit thicker and more tender
- Mild flavor that absorbs marinade well
- A great all-around option
No matter the cut, marinating the steak is essential for both tenderness and flavor.
