Understanding the Quality of Costco’s Skirt Steak

The Quality of Costco’s Skirt Steak

Costco is renowned for offering fresh, quality meat products, and their skirt steak is no exception. Originating from large wholesalers, often traceable back to farm-bred cattle, the skirt steak at Costco meets the typical high standards associated with the retail giant. The skirt steak is often a USDA Choice grade, which assures consumers of high-quality, tender, and flavorful meat. This grade is only a step below Prime, beef’s highest grade, indicating that you are getting an excellent cut of meat for your money.

The standout characteristic of Costco’s skirt steak is its thickness and marbling. The marbling, or the intramuscular fat veining, is especially noticeable and is a significant factor in contributing to the steak’s succulence and rich flavor upon grilling. Moreover, the steak often exhibits a bright red color, which is a common indicator of freshness.

Selecting the Best Skirt Steak at Costco

When choosing skirt steak at Costco, there are various factors to consider. Firstly, check the color of the meat; it should be a vibrant red hue and not overly dark, which might suggest it is not at its freshest. Secondly, look for marbling. A steak with a good amount of fat veins will result in a juicier, more flavorful steak. Nonetheless, excessive fat need not deter you, as it can be trimmed at home or render down upon grilling.

The steak’s thickness is very important, too. As a rule of thumb, a skirt steak should be thin enough to cook quickly on high heat, but thick enough to still offer a juicy bite. Too thin, and the steak risks becoming overdone too quickly; too thick, and it may end up being tough. Costco usually pre-packages their skirt steaks with multiple pieces per package. Thus, if one skirt steak piece isn’t up to your standards, there will typically be other pieces in the same package to choose from.

Costco’s commitment to quality ensures that their skirt steak, or “Arrachera,” is of high standard, making it a favorite choice for many looking to enjoy this particular cut of beef. If you’re shopping at a Costco in a region with a significant Spanish-speaking population or in a country like Mexico, the term “Arrachera” might be more prominently displayed.

Comparison to Other Supermarket Offerings

In comparison to other grocery retailers, Costco’s skirt steak is a game-changer. While many high-end stores may offer similar cuts of meat, Costco manages to deliver the same quality and taste but at a more competitive price.

Discount chains may tempt consumers with lower prices, but the danger lies in inconsistency in quality. Costco, however, offers an assurance of consistent, top-notch quality owing to their robust relationships with established meat providers. This ensures that the skirt steaks you purchase from Costco are always a top choice for your grilling season essentials.

Preparation and Marinade Tips for Skirt Steak

Cooking Tips and Basics for Grilling Skirt Steak

Costco’s skirt steak is a beef cut ideally suited for grilling, known for its distinctive flavor and sold as a long, flat piece. Before grilling, rinse the steak well under cold water and then pat it dry using a paper towel to eliminate any remaining blood or packaging residues. After that, examine it for any excessive fat or silver skin, which can cause the meat to become chewy. If you find any, use a sharp knife to carefully remove these portions.

Cutting your Skirt Steak

When cutting the skirt steak, it is imperative to cut against the grain to maximize tenderness. The grain refers to the direction in which the muscle fibers are aligned. Identifying the grain in skirt steak is usually easy due to its string-like fibers that run down the length of the steak. Instead of long strips, aim to cut the steak into 4 to 6-inch pieces that are easier to manage on the grill.

Marinating your Skirt Steak

Marinating the skirt steak is non-negotiable if you desire a juicy, flavorful steak. Plus, the acidic ingredients in the marinade help to tenderize this naturally tough cut of beef. The marinade could be as simple as olive oil, citrus juice, garlic, and your favorite herbs and spices. For best results, marinate your skirt steak for at least 2 hours, although overnight marination will allow for the most flavor penetration.

Allergy-friendly and Diet-specific Marinade Options

For individuals with specific dietary needs or allergies, there are plenty of marinade options. Gluten-free soy sauce or tamari can be used in place of traditional soy sauce. Use apple cider vinegar for a paleo-friendly option. For a dairy-free alternative, replace any butter with olive oil or avocado oil. For those on a keto diet, focus more on high-fat, low-carb options, such as a marinade made from olive oil, herbs, and spices.

Flavoring Tips for Skirt Steak

Beyond the marinade, include a finishing touch to the skirt steak right after grilling. You can brush it with garlic-infused butter for a flavor boost or sprinkle it with coarse sea salt to intensify the savoriness. For an unconventional but exciting flavor profile, consider running some fresh lime zest and chili powder over the cooked skirt steak for a zesty, spicy finish.

When grilling skirt steak, especially from a top-notch source like Costco, a crucial step to remember is the rest period after the meat has been grilled. Allow the steak to sit for at least five minutes after cooking finishes. This period isn’t wasting time but rather lets the juices redistribute back into the steak, enhancing its mouthwatering taste when bitten into. Don’t skip this process – it’s as vital as the initial preparation of the steak.

Chimichurri Marinade for Costco Skirt Steak

When it comes to enhancing the rich flavors of skirt steak, few marinades can rival the vibrant and tangy notes of chimichurri. Originating from Argentina, this green sauce is not only a fantastic marinade but also serves as an excellent accompaniment to grilled meats, especially beef. Its combination of fresh herbs, garlic, vinegar, and chili provides a zesty counterpoint to the beefy richness of skirt steak.

Chimichurri Marinade Recipe:


  • 1 cup fresh flat-leaf parsley, finely chopped
  • 4 cloves garlic, minced
  • 2 tablespoons fresh oregano (or 2 teaspoons dried)
  • 1/2 cup extra-virgin olive oil
  • 2 tablespoons red wine vinegar
  • 1 teaspoon red pepper flakes (adjust to taste)
  • Salt and pepper to taste
  • Zest and juice of 1 lemon


  1. In a mixing bowl, combine the parsley, garlic, oregano, and lemon zest.
  2. Slowly drizzle in the olive oil while whisking to blend the ingredients.
  3. Add the red wine vinegar, lemon juice, and red pepper flakes. Mix well.
  4. Season with salt and pepper according to your preference.
  5. Place your Costco skirt steak in a large resealable bag or shallow dish and pour the chimichurri marinade over it. Ensure the steak is well-coated and marinate for at least 2 hours, preferably overnight, in the refrigerator.

For those who might be pressed for time or prefer a ready-to-grill option, Costco offers marinated skirt steaks from various brands, including those labeled as “Arrachera.” These pre-marinated options capture the essence of traditional flavors and offer a convenient alternative to homemade marinades. While making your own chimichurri provides a personalized touch, the Arrachera brands at Costco ensure that you’re getting a flavorful and quality product that’s grill-ready. Whether you opt for a DIY approach or a store-bought solution, the end result promises to be a delicious, mouth-watering skirt steak, perfect for any occasion.

Grilling Techniques and Tips

Mastering Your Skirt Steak Grilling Techniques

To further build on that perfect grilling for your skirt steak, you’ll need to understand the importance of heat control and timing. With skirt steak, an ideal grilling temperature tends to fall around 450°F to 500°F. Why so high, you may ask? This temperature range guarantees a hearty sear on the steak’s surface, locking in its succulent juices and enriching the overall flavor. A perfect skirt steak isn’t a miracle—it’s a matter of technique!

Timing Per Side and Checking Doneness

Generally speaking, the skirt steak should be grilled for about 2-4 minutes per side for medium-rare to medium doneness. However, due to differences in steak thickness and grill heat, this time may vary. A reliable method to confirm doneness is the use of an instant-read digital meat thermometer. For medium-rare steak, the internal temperature should read around 130-135°F, while a medium steak should register at about 140-145°F.

Grill Mar and Juice Retaining Techniques

To achieve eye-catching grill marks, place your steak at a 45-degree angle to the grates. After about 1-2 minutes, rotate the steak in the opposite direction. This will give a crosshatch pattern of grill marks. Flip and repeat on the other side.

To retain the juices and flavors, resist the temptation to frequently prod, poke, or flip the steak. This can puncture the meat and allow some of the flavorful juices to escape. It’s also very important to let your steak rest for at least 5 minutes after grilling. This allows the juices to redistribute throughout the steak, leading to a more flavorful and tender bite.

Recommended Grilling Tools

Grilling skirt steak requires some basic but vital grilling tools. A quality grill, preferably one with a temperature gauge, ensures consistent high heat necessary for searing steaks. Long-handled tongs are perfect for flipping and moving the steak around on the grill, without getting too close to the heat. Finally, an instant-read digital thermometer is essential in determining the steak’s internal temperature and hence, its doneness.

Serving and Pairing Ideas

Unlocking Skirt Steak Potential: Perfect Pairings and Serving Ideas

Thanks to its robust flavor and tender constitution, skirt steak provides the perfect canvas for a myriad of sides and dishes. For a traditional, hearty grill meal, combine your skirt steak with grilled accompaniments such as bell peppers, zucchini, and asparagus, or venture down the comfort food route with roasted potatoes or corn on the cob.

If you’re opting for a lighter meal, a fresh salad topped with slices of your grilled skirt steak, complemented by a zesty vinaigrette effortlessly melds the tender savory steak with the freshness of the greens. You could also thinly slice your grilled steak to add a smoky depth to tacos, fajitas, or sandwiches, amplifying the meals with an added layer of complexity in flavor.

Wine Pairings: Complementing Skirt Steak with Wine

When it comes to wine, bold red wines are traditionally recommended with steak. For skirt steak specifically, a Malbec or a Zinfandel works well. Malbec is known for its dark fruit flavors and smoky finish, which matches well with the robust flavors of the grilled steak. Zinfandels are typically high in alcohol and tannin, adding a balance and contrast to the richness of the skirt steak.

Presentation Tips: The Grand Finale

Presenting your grilled skirt steak to your guests can be as important as the cooking process itself. To start, allow the steak to rest after grilling for about 5-10 minutes to let the juices redistribute throughout the meat. This will yield a more tender, flavorful steak.

When slicing the steak, make sure to cut against the grain, as it will make the meat easier to chew and enhances the perceived tenderness of the steak. A well-presented and wisely cut piece of steak can greatly improve the dining experience.

If you’re serving the steak whole, you might choose to garnish it with fresh herbs like cilantro or parsley. If serving it sliced, fan out the pieces on the plate gently and consider adding a side of chimichurri sauce or a cream-based dressing for additional flavor and flair.

These serving, pairing, and presentation tips can greatly enhance your grilling season experience, taking your skirt steak from Costco from plain to impressive. The harmony of well-chosen sides, complementary wines, and a visually appealing presentation can create a truly memorable meal around the grill.
