Costco is a popular wholesale store that offers a wide array of products at competitive prices. While many people are familiar with their selection of bulk goods, Costco is also known for their high-quality meat department. One item that stands out among their meat options is the Costco St Louis ribs. These ribs are well-marbled, bone-in, and have a mouthwatering flavor that makes them a favorite among ribs enthusiasts.

If you’re looking to cook up some delicious ribs for your next meal, but aren’t sure where to start, then you’ve come to the right place! In this guide, we’ll walk you through everything you need to know about cooking Costco St Louis ribs.

What Are St Louis Ribs?

St Louis style ribs refer to a particular cut of pork spare ribs that have been trimmed and squared off into a rectangle shape. Unlike baby back ribs, which come from the hog’s backbone, St Louis style ribs are cut from the lower part of the breastbone. This results in a larger and meatier rib with more marbling than other cuts.

The term “St Louis” comes from the city where they were first popularized in the 20th century. However, these ribs are now widely available in most grocery stores and are frequently seen on restaurant menus.

Choosing the Right Ribs at Costco

When purchasing Costco St Louis ribs, there are a few factors you should consider to ensure you get the best quality meat.

Firstly, check for fresh-looking cuts with nice pink color and minimal bruising or discoloration. You can also look for any signs of freezer burn or excessive ice crystals on the ribs’ surface.

Secondly, make sure to check expiration dates on packaged cuts. You want to buy fresh cuts rather than frozen ones whenever possible.

Lastly, note that cuts with an inch or more of solid white fat on top of them are typically more flavorful and tender. Lean cuts, while healthier, tend to dry out more easily during cooking.

Preparing Your Ribs

Before cooking your ribs, there are a few steps you should take to ensure the best results.

First and foremost, thaw out your ribs completely if you purchased them frozen. You can do this by tightly wrapping the ribs in plastic wrap and placing them in the refrigerator overnight. This slow thawing method helps preserve the quality of the meat.

Next, remove any excess fat from the ribs using a sharp knife or kitchen scissors. While some fat is necessary for flavor and tenderness, too much can make your ribs greasy and unappetizing.

Finally, rinse off your ribs under cold water and pat them dry with paper towels. This will help get rid of any bone fragments or extra bits of fat that may still be attached to the meat.

Cooking Methods

When it comes to cooking Costco St Louis ribs, there are several different methods you can use depending on your preference and cooking equipment available.

The most common cooking methods for St Louis ribs include grilling, smoking, and roasting in the oven. Each of these methods produces slightly different results in terms of flavor and tenderness, so feel free to experiment with all three to find your favorite.

Whichever method you choose, make sure to season your ribs beforehand with a dry rub or marinade. This will add a burst of flavor to your meat and help tenderize it as well.

Grilling Ribs

Grilling is an excellent option for those who love that classic charred taste on their ribs. It’s also a relatively quick method compared to smoking or roasting in the oven.

To grill your Costco St Louis ribs:

1. Preheat your grill to medium heat.
2. Place your ribs on the grill, bone-side down.
3. Cook for approximately 10-15 minutes per side, basting with your preferred sauce every 5 minutes.
4. Use a meat thermometer to check the internal temperature of your ribs. They should reach 145°F for safe consumption.
5. Once done, let the ribs rest for a few minutes before cutting and serving.

Smoking Ribs

Smoking ribs is a popular method that results in fall-off-the-bone tender meat with a smoky flavor. This method takes longer than grilling but is well worth the wait.

To smoke your Costco St Louis ribs:

1. Prepare your smoker by filling it with charcoal or wood chips and preheating it to 225°F.
2. Add your seasoned ribs to the smoker, making sure to place them bone-side down.
3. Let them smoke for approximately 5-6 hours (depending on the size of your ribs), making sure to add more charcoal or wood chips as needed.
4. Once done, check the internal temperature of the meat with a thermometer; it should be at least 145°F.
5. Let the ribs rest for 10-15 minutes before slicing and serving.

Roasting Ribs

Preparing and Seasoning the Ribs

When it comes to cooking Costco St. Louis ribs, preparation is key. Start by taking the ribs out of the refrigerator and letting them sit at room temperature for at least 30 minutes before cooking. This will allow the ribs to cook more evenly.

Next, remove the membrane from the back of the ribs. This tough layer can prevent seasonings from penetrating and also create a chewy texture. To remove it, use a sharp knife to loosen one corner then grab onto it with a paper towel or kitchen towel and pull it off in one piece.

Once the membrane is removed, season your ribs generously with your choice of rub or seasoning. Popular choices include dry rubs containing spices like paprika, garlic powder, onion powder, and brown sugar. Apply the rub evenly on both sides of the ribs, making sure to cover all areas.

If you have time, let the seasoned ribs sit in the refrigerator for a few hours or overnight to allow them to marinate and develop deeper flavors.

Choosing Your Cooking Method

There are several methods for cooking Costco St. Louis ribs, each resulting in deliciously tender and juicy meat. The most common methods include grilling, smoking, baking or slow-cooking.

Grilling: This method involves directly cooking the ribs on a grill over medium heat for about 25-30 minutes per side until they are fully cooked. Make sure to keep an eye on them as they can easily burn due to their high sugar content.

Smoking: For those looking for even more flavor, smoking is a great option. It involves slow-cooking the ribs in a smoker over indirect heat using wood chips for added smoke flavor. Depending on your smoker’s temperature and type of wood used, smoking can take anywhere from 3-6 hours.

Baking: Baking is an easy and convenient way to cook ribs. Simply place the seasoned ribs in a baking dish, cover with foil, and bake in the oven at 300°F for 2-3 hours until they are fully cooked and tender.

Slow-Cooking: Another effortless method for cooking Costco St. Louis ribs is using a slow cooker. Place the seasoned ribs in the slow cooker, add your choice of liquid (such as broth or BBQ sauce), and cook on low for 6-8 hours or high for 3-4 hours.

Cooking and Finishing Your Ribs

Whichever cooking method you choose, make sure to cook your ribs until they reach an internal temperature of 145°F for medium-rare or 190°F for well-done. Use a meat thermometer to check the temperature in the thickest part of the meat without touching any bones.

Once your ribs are cooked, you can choose to finish them with a glaze or sauce. Simply brush your choice of glaze onto the ribs and return them to the grill, smoker, or oven for about 5 minutes until it is sticky and caramelized.

If using BBQ sauce, be mindful as it can easily burn due to its high sugar content. It’s recommended to add BBQ sauce only during the last 5-10 minutes of cooking time.

Serving and Enjoying Your Ribs

Once your Costco St. Louis ribs are fully cooked and caramelized, remove them from the heat source and let them rest for at least 10 minutes before cutting into them. This allows for the meat juices to distribute evenly throughout which results in much juicier and flavorful ribs.

When serving your ribs, it’s best to cut them between each bone so that each piece has a rib bone attached. This not only looks more appealing but also allows guests to grab a rib without getting their hands messy.

Ribs are perfect for pairing with a variety of sides such as coleslaw, corn on the cob, baked beans, or potato salad. They also go well with a cold beer or your favorite BBQ sauce for dipping.

Now that you know how to cook Costco St. Louis ribs like a pro, it’s time to gather your ingredients and fire up the grill or smoker. With these tips and methods, you’ll be sure to impress your friends and family with deliciously tender and flavorful ribs every time. Experiment with different rubs, sauces, and cooking methods until you find your perfect recipe. Happy cooking!
