Vacio steak, often referred to as flank steak in the United States, is a flavorful and relatively lean cut of beef prized for its rich taste and affordability. This Argentinian favorite is a staple in asados (barbecues) and is increasingly popular in home kitchens worldwide. Mastering the art of cooking vacio steak unlocks a world of culinary possibilities, from simple pan-seared dinners to impressive grilled feasts. This guide provides a comprehensive overview of everything you need to know to cook perfect vacio steak every time.
Understanding Vacio Steak: A Cut Above the Rest
Vacio, derived from the Spanish word for “empty,” refers to the cut’s location on the cow – the flank, specifically the abdominal muscle. This area is characterized by hard-working muscles, which translate to a more robust and pronounced beefy flavor compared to more tender, less-used cuts. While vacio might not be as inherently tender as a ribeye or tenderloin, its flavor profile more than compensates, especially when cooked correctly. Its loose grain also makes it ideal for marinating, allowing it to absorb flavors beautifully.
The key to enjoying vacio steak lies in understanding its characteristics. It’s a relatively thin cut, typically around ¾ to 1 inch thick, and has a distinct grain running lengthwise. This grain is crucial to consider when slicing the cooked steak; cutting against the grain ensures maximum tenderness.
Identifying Quality Vacio
When purchasing vacio steak, look for a vibrant red color and even marbling (the streaks of fat within the muscle). The marbling contributes to the steak’s flavor and juiciness. Avoid steaks that appear dull, dry, or have large areas of fat that haven’t been properly trimmed. Also, consider the thickness of the steak. Uniform thickness is ideal for even cooking.
Ideally, source your vacio from a reputable butcher who can provide information about the cut and its origin. Grass-fed beef tends to have a slightly more intense flavor than grain-fed beef, while the latter typically boasts more marbling.
Preparing Vacio Steak for Cooking: Setting the Stage for Success
Proper preparation is vital for achieving a delicious and tender vacio steak. This involves trimming, tenderizing (if desired), and seasoning.
Trimming and Tenderizing
While some vacio steaks may come pre-trimmed, it’s always a good idea to inspect the cut and remove any excess silver skin or thick layers of fat. Silver skin is a tough membrane that can make the steak chewy, so carefully removing it with a sharp knife is recommended.
Tenderizing vacio is optional, but it can significantly improve the texture, especially if you’re working with a less-than-prime cut. There are several methods to tenderize vacio:
- Mechanical tenderizing: Using a meat mallet or a jaccard (a device with small needles) to break down the muscle fibers. Be careful not to overdo it, as this can make the steak mushy.
- Marinating: Soaking the steak in an acidic marinade (containing ingredients like vinegar, lemon juice, or yogurt) helps to break down proteins and tenderize the meat.
- Salt Brining: Submerging the steak in a saltwater solution can also help to tenderize and season the meat from the inside out.
Seasoning Vacio: Simplicity or Complexity?
When it comes to seasoning vacio, the choice is yours. Simple seasoning with salt and pepper is often sufficient to highlight the natural beefy flavor. However, vacio steak also takes well to more complex flavor profiles.
For a simple seasoning, use coarse kosher salt and freshly ground black pepper. Apply generously to both sides of the steak at least 30 minutes before cooking, or even up to a day in advance (dry brining). This allows the salt to penetrate the meat and enhance its flavor.
For a more complex flavor profile, consider using a dry rub or a marinade. Popular dry rub ingredients include garlic powder, onion powder, paprika, chili powder, cumin, and oregano. Marinating options include chimichurri, soy sauce-based marinades, or herb-infused oil marinades.
Cooking Methods for Vacio Steak: Exploring Your Options
Vacio steak is a versatile cut that can be cooked using various methods, each offering a slightly different result. The most common methods are grilling, pan-searing, and broiling.
Grilling Vacio: The Asado Experience
Grilling is arguably the most authentic and popular way to cook vacio steak, especially when replicating the Argentinian asado. Grilling imparts a smoky flavor and creates a beautiful sear on the outside.
To grill vacio, preheat your grill to medium-high heat. Make sure the grates are clean and lightly oiled. Place the steak on the grill and cook for 3-5 minutes per side for medium-rare, or longer depending on your desired level of doneness. Use a meat thermometer to ensure accuracy; 130-135°F for medium-rare is ideal.
For an authentic asado experience, consider using wood or charcoal to impart a smoky flavor. You can also add herbs like rosemary or thyme to the coals for an extra layer of flavor.
Pan-Searing Vacio: A Quick and Easy Option
Pan-searing is a great option for cooking vacio indoors, especially when you want a quick and easy meal. This method allows you to achieve a beautiful sear and maintain control over the cooking temperature.
To pan-sear vacio, heat a heavy-bottomed skillet (cast iron is ideal) over medium-high heat. Add a high-smoke-point oil, such as canola or avocado oil, to the pan. Once the oil is shimmering, carefully place the steak in the pan. Sear for 3-5 minutes per side, or until desired doneness is reached. Use a meat thermometer to check the internal temperature.
For added flavor, you can add butter, garlic, and herbs to the pan during the last few minutes of cooking. Basting the steak with the melted butter and herbs will enhance its flavor and moisture.
Broiling Vacio: High Heat, Big Flavor
Broiling is another indoor cooking method that uses high heat to quickly cook the steak. This method is similar to grilling, but the heat source is above the steak rather than below it.
To broil vacio, preheat your broiler to high. Place the steak on a broiler pan and position it about 4-6 inches from the heat source. Broil for 3-5 minutes per side, or until desired doneness is reached. Use a meat thermometer to check the internal temperature.
Be sure to watch the steak carefully while broiling, as it can burn easily.
Achieving Perfect Doneness: The Importance of Temperature
Regardless of the cooking method you choose, achieving the desired level of doneness is crucial for enjoying vacio steak. Using a meat thermometer is the most accurate way to ensure your steak is cooked to perfection.
Here’s a guide to internal temperatures for different levels of doneness:
| Doneness | Internal Temperature |
|---|---|
| Rare | 125-130°F |
| Medium-Rare | 130-135°F |
| Medium | 135-145°F |
| Medium-Well | 145-155°F |
| Well-Done | 155°F+ |
Remember that the steak will continue to cook slightly after it’s removed from the heat (carryover cooking), so it’s best to remove it from the heat when it’s a few degrees below your desired temperature.
Resting and Slicing Vacio: The Final Touches
Resting the steak after cooking is essential for allowing the juices to redistribute throughout the meat. This results in a more tender and flavorful steak. Let the steak rest for at least 10 minutes before slicing. Tent it loosely with foil to keep it warm.
Once the steak has rested, it’s time to slice it. Remember that vacio steak has a distinct grain running lengthwise. To ensure maximum tenderness, slice the steak against the grain into thin slices. This shortens the muscle fibers, making them easier to chew.
Serving Suggestions for Vacio Steak: Completing the Meal
Vacio steak is incredibly versatile and pairs well with a variety of sides. Here are a few serving suggestions:
- Chimichurri: A classic Argentinian sauce made with parsley, garlic, oregano, red wine vinegar, and olive oil.

What exactly is Vacio steak, and where does it come from?
Vacio steak, also known as flank steak outside of Argentina, is a flavorful and relatively lean cut of beef taken from the abdominal muscles of the cow. Specifically, it's the cut located between the ribs and the rear quarter, offering a good balance of tenderness and robust beefy flavor. Its unique grain structure makes it ideal for grilling and slicing against the grain.
The key to its popularity in Argentinian cuisine lies in the way it's often prepared: typically grilled over high heat, allowing the exterior to develop a beautiful crust while maintaining a juicy interior. This method maximizes the cut's inherent flavors, creating a truly memorable steak experience that showcases Argentinian grilling traditions.
What's the best way to prepare Vacio steak for grilling?
Proper preparation is key to achieving the best results with Vacio steak. Begin by trimming any excess fat from the surface, leaving a thin layer for added flavor and moisture during cooking. Pat the steak dry with paper towels; this promotes a better sear on the grill.
Before grilling, generously season the steak with coarse salt and freshly ground black pepper. While Argentinian tradition often sticks to simple seasoning, you can add other spices like garlic powder or paprika if desired. Allow the steak to sit at room temperature for about 30 minutes before grilling; this helps it cook more evenly.
How long should I grill Vacio steak to achieve the desired doneness?
Grilling time for Vacio steak depends heavily on the thickness of the cut and your desired level of doneness. For a typical 1-inch thick Vacio steak, grilling for approximately 3-4 minutes per side over medium-high heat should yield a medium-rare result. Use a meat thermometer to ensure accuracy.
