Step 1

Preheat oven to 350 degrees.

Step 2

Place onion wedges in bottom of dutch oven.

Step 3

Rinse and pat dry the brisket with paper towels.

Step 4

Arrange corned beef brisket on top of onion slices.

Step 5

Sprinkle brisket with dry rub and steak seasoning. Or, use the spice packet that comes with corned beef.

Step 6

Pour bottles of dark beer and beef stock (or water) into the dutch oven. Make sure liquid level reaches the top of the meat.

Step 7

Cover dutch oven with lid.

Step 8

Place in 350 degree oven. Cook for 1 hour.

Step 9

Reduce heat to 300 degrees. Cook for 2 hours.

Step 10

Check liquid level at this point. If it has cooked down too low, add a cup of water or broth to prevent scorching.

Step 11

Turn the brisket over. Add carrots and potatoes to the pot. Sprinkle with steak seasoning or salt and pepper. Cook 1 hour.

Step 12

Add cabbage to the pot. Cook 1 more hour.

Step 13

Serve straight from the pot or transfer to a large baking dish and serve with spicy mustard. Be sure to slice meat across the grain for a tender brisket. Slicing across the grain also keeps the meat from shredding.
