How To Cook Corned Beef Perfectly For Reuben Sandwiches

If you’re craving a classic Reuben sandwich, the star ingredient has to be perfectly cooked corned beef. This tender, flavorful meat gives the sandwich its signature taste and texture. Knowing how to cook corned beef properly is key to making a sandwich that bursts with the right blend of savory and juicy notes.

Corned beef often intimidates home cooks because it’s usually purchased raw and requires proper seasoning and slow cooking to achieve a tender bite. Whether you’re starting with a brisket flat or point cut, cooking corned beef isn’t complicated once you understand the basic methods and timing.

In this guide, you’ll learn how to prepare corned beef from scratch, the best ways to cook it for Reuben sandwiches, and insider tips to boost flavor and texture. This step-by-step approach will have you slicing sumptuous corned beef that melts perfectly on rye bread.

Choosing the Right Corned Beef for Reuben Sandwiches

First, consider the cut of corned beef to use. Corned beef typically comes in two main cuts – flat and point. The flat cut is leaner and easier to slice, making it ideal for sandwiches. The point cut has more marbling, resulting in richer flavor but can be harder to get uniformly thin slices.

Look for corned beef that is fresh or pre-brined and vacuum-sealed. Avoid corned beef with excessive preservatives or added sugars for a purer flavor. You can also buy a corned beef brisket that hasn’t been cooked yet, giving you full control over the seasoning and tenderness.

Preparing Corned Beef Before Cooking

Rinse and Soak to Remove Excess Salt

Corned beef is cured using a salt brine, so rinsing before cooking is essential. Place the meat in cold water and soak for at least 30 minutes to help draw out extra salt, especially if it’s heavily cured. Replace the water halfway through if possible.

Adding Aromatics and Spices

While basic corned beef comes with seasoning packets, enhancing the boil with fresh aromatics can elevate the final flavor. Common additions include bay leaves, peppercorns, mustard seeds, and garlic cloves. Onions and carrots in the cooking liquid bring sweetness and depth.

How To Cook Corned Beef: Methods That Work Best

Slow cooking corned beef is necessary to break down the tough fibers, yielding tender slices. There are several effective methods depending on the equipment and time you have.

Boiling or Simmering on the Stovetop

Place the rinsed corned beef in a large pot, submerge in water, and add your chosen spices and aromatics. Bring to a boil then lower to a simmer. Cover and gently simmer for 2.5 to 3.5 hours, depending on the size, until the meat is fork-tender. Avoid boiling vigorously to keep the meat juicy.

Slow Cooker Method

For convenient hands-off cooking, use a slow cooker. Place the corned beef and aromatics inside, cover with water or broth, and cook on low for 8 to 10 hours. This method is excellent for ensuring tenderness without frequent monitoring.

Oven-Braising for Rich Flavor

Oven cooking combines slow simmering and roasting benefits. Place the corned beef in a roasting pan with liquid and cover tightly with foil. Bake at 300°F (150°C) for about 3 to 4 hours, checking for tenderness. The oven method helps develop savory brown edges.

Checking for Doneness and Resting

Corned beef is done when it’s easily pierced with a fork and shreds slightly under gentle pressure. Overcooking can cause dryness, so aim for tender but still moist meat. Rest the meat for 10 to 15 minutes after cooking to redistribute juices and ease slicing.

Slicing Corned Beef for Your Reuben

For the classic Reuben sandwich, thin slices are essential. Slice against the grain for maximum tenderness. If using a flat cut, slicing thinly is easier due to its uniform texture. If you have a point cut, take extra care to find the grain direction as it can change within the cut.

Enhancing Flavor Before Assembling Your Sandwich

Once sliced, you can add extra flavor by lightly pan-searing the corn beef slices to develop a crust or warming them gently in mustard or a splash of cooking broth. This step adds a delicious caramelized edge that complements the tangy sauerkraut and creamy Russian dressing traditionally used in Reubens.
