Why You’ll Love This Baked Corned Beef Recipe

Hands-Off Cooking: Just assemble, cover, and let the oven do all the heavy lifting.
Bold, Rich Flavor: The beer infuses the meat with depth while the mustard and seasoning packet form a delicious crust.
Tender & Juicy: Low and slow roasting ensures every bite is melt-in-your-mouth perfection.
Minimal Ingredients: You only need 3 key ingredients, but the taste is anything but basic.

Ingredients You’ll Need

4 pounds corned beef brisket (with seasoning packet), rinsed and patted dry
1 cup beer (Lager or Pilsner recommended)
1/4 cup stone ground mustard

Note: Make sure to keep the fat side of the brisket facing up for best results. This allows the fat to self-baste the meat during roasting, adding both moisture and flavor.

Step-by-Step Instructions

🔥 Step 1: Preheat and Prep

Preheat your oven to 325°F (163°C). Spray a 13 x 9 x 2-inch baking dish with non-stick cooking spray to prevent sticking and ease cleanup.

🥩 Step 2: Assemble the Dish

Place the rinsed and dried brisket into the baking dish fat side up. Pour 1 cup of beer around the brisket in the dish—don’t pour directly over the top.

🖌️ Step 3: Add Flavor

Brush stone ground mustard over the top of the brisket, then sprinkle on the seasoning packet that came with your corned beef. This creates a delicious, tangy, and savory crust.

⏲️ Step 4: Roast Low and Slow

Cover the baking dish tightly with aluminum foil and roast in the preheated oven for 3 ½ hours.

🔓 Step 5: Uncover and Finish Roasting

Remove the foil and continue roasting the brisket uncovered for an additional 30 minutes. This final step helps develop that rich, golden-brown crust.

🧂 Step 6: Rest and Serve

Remove from the oven and allow the corned beef to rest for 10 minutes before slicing. This helps retain the juices. Serve with roasted potatoes and carrots, or your favorite side dishes.

Kitchen Equipment Needed

To make this baked corned beef recipe, you’ll need:

13 x 9 x 2-inch baking dish
Aluminum foil
Basting brush or spoon
Sharp knife for slicing
Cutting board
Non-stick cooking spray

Expert Tips & Notes

Choose the Right Beer: Use a Lager or Pilsner for the best flavor—avoid dark stouts or IPAs, which can overpower the meat.
Don’t Skip Rinsing: Rinsing the corned beef brisket removes excess brine and salt, ensuring a more balanced flavor.
Fat Side Up: Always roast with the fat side up for self-basting and better moisture retention.
Resting is Crucial: Resting after baking lets the juices redistribute so you don’t lose them when slicing.

Recipe Variations & Swaps

Want to change things up? Here are a few tasty variations:

Glaze It: Add brown sugar or honey to the mustard for a sweet-and-savory crust.
Skip the Beer: Substitute beef broth or apple cider if you prefer a non-alcoholic option.
Add Veggies: Toss carrots, onions, and baby potatoes into the pan for a one-dish meal.
Try Dijon: Swap stone ground mustard for Dijon for a smoother, spicier flavor.

Frequently Asked Questions (FAQ)

Can I use a different type of mustard?

Yes! While stone ground mustard adds texture and flavor, you can substitute Dijon, spicy brown, or even honey mustard depending on your preference.

Do I have to use beer?

Not at all. Beef broth, apple cider, or even water with a splash of vinegar can be used in place of beer. The liquid helps tenderize the meat during roasting.

Can I make this in a slow cooker?

While this recipe is designed for the oven, you can adapt it for a slow cooker. Cook on low for 8 hours, then transfer to a baking sheet and broil for 5-10 minutes to develop a crust.

Is this gluten-free?

If you use a gluten-free beer or substitute broth, and ensure your mustard and seasoning packet are gluten-free, then yes, it can be made gluten-free.
