The Reuben sandwich is a culinary masterpiece, a salty, tangy, and melty marvel that has earned its place in the pantheon of great American deli eats. While you can certainly buy pre-sliced corned beef at the grocery store, nothing compares to the depth of flavor and tender texture of a home-cooked brisket. Learning how to cook corned beef for Reuben perfection is the secret to transforming a standard lunch into a gourmet experience. This guide will walk you through everything from selecting the right cut to the final assembly, ensuring your next sandwich is the talk of the town.
Choosing the Right Cut for Your Reuben
Before you even turn on the stove, you have to choose your meat. When you go to the butcher, you will usually see two options: the point cut and the flat cut.
The flat cut is the most popular choice for Reuben sandwiches. It is leaner and more uniform in shape, which makes it much easier to slice into those beautiful, even ribbons that stack perfectly on rye bread. However, if you prefer a richer, more decadent sandwich, the point cut contains more intramuscular fat. This extra marbling leads to a more tender, “shreddy” result, though it is harder to get clean slices from it. For the classic deli look, stick with a high-quality flat cut.
Preparing Your Corned Beef
Most corned beef comes pre-brined in a vacuum-sealed bag. This brine is packed with salt and nitrates, which preserve the meat and give it that signature pink color.
One professional tip is to rinse the brisket under cold water before cooking. This removes the excess surface salt and the gelatinous goop from the packaging. If you skip this step, your final sandwich might be overwhelmingly salty, especially once you add the sauerkraut and Swiss cheese. After rinsing, pat the meat dry. You will likely find a small spice packet included in the package; don’t throw this away, as it contains the essential mustard seeds, coriander, and bay leaves that define the flavor profile.
The Best Cooking Methods for Reuben Success
There are several ways to tackle the cooking process, each offering its own benefits. The goal is always the same: breaking down the tough connective tissue in the brisket until it is “fork-tender.”
The Traditional Stovetop Simmer
This is the classic method. Place your brisket in a large Dutch oven or pot and cover it with water by at least two inches. Add the spice packet and perhaps some aromatics like a halved onion, a few cloves of garlic, and a stalk of celery.
Bring the water to a boil, then immediately reduce the heat to a low simmer. You do not want a rolling boil, as high heat can toughen the proteins. Cover the pot and let it cook for about 45 to 50 minutes per pound. You are looking for an internal temperature of about 145 degrees Fahrenheit for food safety, but for the best texture, most chefs aim for 190 degrees Fahrenheit to 200 degrees Fahrenheit, where the collagen fully dissolves.
The Slow Cooker Method
If you want to set it and forget it, the slow cooker is your best friend. Place the brisket (fat side up) in the crock, add the spices and just enough water or beef broth to cover the meat. Set it to low and let it go for 8 to 10 hours. This slow, gentle heat produces an incredibly tender result that almost melts in your mouth.
The Oven Braise
For a slightly deeper flavor, you can braise the beef in the oven. Place the brisket in a roasting pan with liquid and spices, cover tightly with heavy-duty aluminum foil, and bake at 300 degrees Fahrenheit. This method allows for a bit of “bark” to form on the fat cap if you uncover it for the last 30 minutes of cooking.
Calculating Your Yield
One common mistake is not cooking enough meat. Brisket shrinks significantly during the cooking process as the fat renders out and the moisture evaporates. To ensure you have enough for a crowd, use the following calculation to estimate your final yield:
| Raw Weight | Yield Multiplier | Estimated Cooked Weight |
|---|---|---|
| 1.0 lb | 0.65 | 0.65 lbs |
| 4.0 lbs | 0.65 | 2.6 lbs |
Since a standard Reuben uses about 4 to 6 ounces of meat, a 4-pound raw brisket will yield roughly 7 to 10 sandwiches.
The Importance of the Rest and the Slice
Once the meat is done, do not cut into it immediately. This is the most crucial step. Let the corned beef rest on a cutting board for at least 15 to 20 minutes. Resting allows the juices to redistribute throughout the meat. If you cut it too soon, all that moisture will run out onto the board, leaving you with dry beef.
When you are ready to slice, look for the grain. The “grain” refers to the direction the muscle fibers run. Always slice against the grain. If you slice with the grain, the meat will be chewy and stringy. By cutting across the fibers, you shorten them, making every bite tender and easy to chew. For a Reuben, thin slices are generally preferred over thick slabs.
Assembling the Masterpiece
Now that you have perfected the beef, the assembly is what brings it all together.
- The Bread: Traditional Jewish rye or marbled rye is a must. It needs to be sturdy enough to hold the moist ingredients.
- The Dressing: Russian dressing is the traditional choice, providing a spicy, horseradish-forward kick. Thousand Island is a popular, sweeter alternative.
- The Cheese: Sliced Swiss cheese provides a nutty, mild flavor that melts beautifully.
- The Sauerkraut: Ensure you drain your sauerkraut well and even squeeze it dry. If it is too wet, it will turn your bread into a soggy mess.
To get that perfect deli finish, butter the outside of your bread and grill the sandwich in a skillet over medium heat until the bread is golden brown and the cheese has completely melted into the nooks and crannies of the corned beef.
FAQs
How do I know when the corned beef is finished cooking?
The best way to tell is by using a meat thermometer to check for an internal temperature between 190 degrees Fahrenheit and 200 degrees Fahrenheit. If you do not have a thermometer, you can use the fork test. Insert a fork into the thickest part of the meat; if it slides in and out with almost no resistance, the beef is ready.
Should I cook the corned beef with the fat cap on?
Yes, you should always cook the brisket with the fat cap intact. In a slow cooker or oven, place the fat side up so that as the fat melts, it bastes the meat, keeping it moist and adding flavor. You can always trim away any excess fat after the meat has finished cooking and resting.
Can I use beer instead of water for the cooking liquid?
Absolutely. Using a dark stout or an Irish ale adds a wonderful complexity and a slight bitterness that complements the salty beef perfectly. Simply replace half or all of the water with your beer of choice. Just be aware that the sugars in the beer can cause the liquid to foam up initially, so keep an eye on the pot.
How long does cooked corned beef last in the refrigerator?
Once cooled, you can store your cooked corned beef in an airtight container for 3 to 4 days. If you find you have too much, it freezes remarkably well. Wrap it tightly in plastic wrap and then foil, and it will stay good in the freezer for up to 3 months. This is great for quick Reuben cravings later on.
Why is my corned beef tough even after hours of cooking?
If the meat is tough, it usually means it hasn’t cooked long enough to break down the connective tissues. Brisket is a very tough muscle. If you test it and it feels rubbery, put the lid back on and continue simmering. Even another 30 to 60 minutes can make a world of difference in the final texture.
