🔍 What is Flank Steak and Why It’s So Great for Tacos
Flank steak is a beef steak cut from the abdominal muscles of the cow. It’s recognized for its deep flavor and lean texture. Unlike some fattier cuts, flank steak is lean and muscular and really shines when marinated, which tenderizes the flesh and imparts flavor.
You may be asking yourself how flank steak stacks up to other taco workhorses like skirt steak or sirloin. The Skirt Steak is also very flavourful, it just has a little bit of gristle in it. The sirloin’s tender but not deeply beefy flavor. Flank steak is just about the perfect thing — beefy and flavorful, and when it is marinated correctly, wonderfully tender.
Plus, flank steak contains a good deal of protein and less fat, which can be good news if you’re looking for a tasty, healthy taco filling 🥩.
🧪 The Secrets to the Best Flank Steak Taco Marinade 🥄
Why does marinating make such a difference? The mystery is in the interplay of the ingredients with the meat.
- Acidic components, such as lime juice or vinegar, help to break down the robust muscle fibers in flank steak. This tenderizing action helps to remove some of the chewiness and makes the meat easier to bite into.
- Oils: For example, olive oil, which performs two important functions: It moisturizes the meat and it carries the flavors of the herbs and spices deep in the steak.
- Seasonings and Spices such as garlic, cumin, and chili powder add depth and a savory element to the beef that takes it one (vaca) step further while still yielding that familiar punch of Mexico-inspired tacos 🌶️.
Timing is crucial. Marinate too short and the flavors won’t penetrate to the core; marinate too long and the acid can start to “cook” the meat, leaving it with an unpleasant mushy texture. For flank, that’s a 4 to 6 hour sweet spot, but overnight marinating can be divine, too, if you’re a planner.

🔥 How to Cook Marinated Flank Steak Tacos
To make the most of your marinade, the cooking method is as important as the steak.
- Grilling: This is the traditional technique. Preheat your grill on high heat 🔥. Cook steak 4-5 minutes per side for medium-rare depending on thickness. The grilling imparts a smoky char that plays perfectly off the flank steak taco marinade.
- Pan-searing: If you don’t own a grill, a heavy skillet or cast-iron pan is a good substitute. Preheat a pan over medium-high heat with a little oil in the bottom, then sear the steak as if you were cooking on a grill.
- Rest: After the steak is cooked, rest it for 5-10 minutes. Thanks to this, the juices have a chance to redistribute, and every bite is juicy and tasty 🥩.
- Slicing: Always slice flank steak against the grain (e.g., perpendicular to the muscle fibers). This breaks down toughness and makes your taco meat tender every time you take a bite.
