Savory Corned Beef Roast

Growing up, corned beef only made an appearance once a year in our house – St. Patrick’s Day. Mom would toss it in a pot of water with the seasoning packet and hope for the best. Sometimes it turned out tender, other times it was about as chewy as my dad’s old work boots.

It wasn’t until I started experimenting in my own kitchen that I discovered roasting corned beef instead of boiling it. The method is just as simple, but the results are so much more reliable. No more crossing your fingers and praying it turns out edible – this roasting technique gives you tender, flavorful meat every single time.

What Kind of Corned Beef Should I Use?

When shopping for corned beef, you’ll typically find two different cuts at the store: the flat cut and the point cut. The flat cut is leaner and has a more uniform shape, making it easier to slice and present nicely on your plate. The point cut has more marbling (fat running through it) which makes it more flavorful but slightly harder to slice neatly. For this recipe, either cut will work well, though I tend to prefer the flat cut for its reliability and presentation. Most corned beef comes with a spice packet, but if yours doesn’t, you can easily make your own blend with peppercorns, bay leaves, and mustard seeds. Just make sure to rinse your corned beef before cooking – this helps remove any excess salt from the brining process.

Options for Substitutions

While some ingredients in this classic dish are essential, there’s still room for some swaps:

• Corned beef brisket: This is the star of the show and can’t be substituted – it’s what makes corned beef, well, corned beef! Just make sure to keep the spice packet that comes with it.
• Potatoes: Any potato variety works here – red potatoes, Yukon golds, or russets are all good options. Just keep the pieces similar in size for even cooking. You could even use turnips or parsnips for a lower-carb option.
• Carrots: Regular carrots can be swapped with baby carrots if that’s what you have. You can also use parsnips for a different flavor, or rainbow carrots to add some color to your dish.
• Onion: Yellow, white, or sweet onions all work great. If you’re out of fresh onions, you can use 1 tablespoon of onion powder, though fresh is better for this recipe.
• Garlic cloves: No fresh garlic? Use 1/2 teaspoon of garlic powder for each clove. You can also use pre-minced garlic from a jar – about 1/2 teaspoon equals one clove.

Watch Out for These Mistakes While Cooking

The biggest mistake when cooking corned beef is rushing the process – this tough cut needs a long, slow cook at a gentle simmer (not a rolling boil) to become tender, typically about 50 minutes per pound. A common error is not rinsing the meat before cooking, which can make your dish too salty – give it a quick rinse under cold water and pat it dry before starting. For the most flavorful results, always place the meat fat-side up in your pot, allowing the fat to baste the meat as it cooks, and resist the urge to check on it too frequently since lifting the lid releases precious heat and moisture. To ensure perfect doneness, use a meat thermometer to check that the internal temperature reaches 145°F, then let it rest for 10-15 minutes before slicing against the grain – this makes the difference between tender, easy-to-cut meat and a stringy, tough mess.

What to Serve With Corned Beef?

While this recipe already includes classic sides like potatoes and carrots, you can round out your meal with a few extra dishes that complement the salty, rich flavors of corned beef. A side of buttered cabbage or sautéed Brussels sprouts adds a traditional touch that pairs perfectly with the meat. For some tang to cut through the richness, try serving quick-pickled vegetables or a mustard-based coleslaw on the side. If you’re looking to add some bread to the meal, warm slices of Irish soda bread or dark rye bread are perfect for soaking up the flavorful cooking liquid.

Storage Instructions

Keep Fresh: Your leftover corned beef will stay good in the fridge for up to 4 days when stored in an airtight container. I like to keep the meat and vegetables separate – this way, you can easily grab what you need for sandwiches or quick meals. Pro tip: save any leftover cooking liquid to store with the meat to help keep it moist!

Freeze: Corned beef freezes really well! Place it in a freezer-safe container or heavy-duty freezer bag, and it’ll keep for up to 3 months. The vegetables can be frozen too, but they might be a bit softer when thawed – I usually just store those in the fridge and eat them within a few days.

Reheat: To warm up your corned beef, place it in a pan with a bit of the reserved cooking liquid or beef broth, cover, and heat on low until warmed through. You can also use the microwave, but heat it in short intervals to prevent the meat from drying out. The vegetables can be reheated in the microwave or quickly warmed in a skillet.

Ingredients

• One corned beef brisket (5 1/2 pounds) with spice packet
• 7 small peeled and diced potatoes
• 4 medium peeled and diced carrots
• 1 medium diced onion
• 3 chopped garlic cloves

Step 1: Preheat the Oven

Begin by preheating your oven to 300 degrees F (150 degrees C).

This low and slow cooking approach will ensure the corned beef becomes tender and flavorful.

Step 2: Prepare the Roasting Pan

Place the corned beef brisket in the center of a roasting pan.

Then arrange the potatoes and carrots around the sides, ensuring an even distribution for consistent cooking.

Scatter chopped onions and garlic over the top of the beef and vegetables, which will infuse the dish with savory flavors as it cooks.

Step 3: Season and Add Liquid

Sprinkle the seasoning packet that often comes with corned beef over the brisket to enhance its flavor.

Next, pour in enough water into the roasting pan until the potatoes are almost covered.

This will help keep the brisket moist as it roasts.

Step 4: Cover and Roast

Cover the roasting pan with a lid or heavy aluminum foil to trap steam and heat, facilitating the tenderizing process.

Place the covered pan in the preheated oven and roast for approximately 5 to 6 hours, or until the corned beef is tender enough to flake apart easily with a fork.

Step 5: Serve

Once cooked, carefully remove the pan from the oven and allow it to cool slightly before serving.

Slice the beef and serve alongside the roasted vegetables.

Enjoy your perfectly tender corned beef meal!
