Ingredient Notes & Substitutions
Corned beef brisket: Flat-cut brisket is easier to slice and leaner, while point-cut is fattier and more flavorful.
Fresh thyme: Substitute dried thyme if needed, but fresh gives stronger aromatics.
Whole grain mustard: Dijon can be used as an alternative for a smoother texture.
Cabbage: Red cabbage or a mix of red and green can be used for a colorful twist.
Horseradish Sauce: Replace with mustard-based sauce if preferred.

Instructions
Step 1: Sear the Beef
Heat a large 12-inch skillet over medium-high heat for at least 2 minutes. Open your package of corned beef and drain the brine into the sink. Add 2 tablespoons of oil to the hot skillet; it should shimmer immediately. Swirl to coat, then add the drained beef. Sear for 2-4 minutes on one side until golden brown, then carefully flip and sear for another 2-3 minutes.
Step 2: Prepare the Cooking Liquid
Place the seared corned beef in a crock pot, fat side up. In a glass measuring cup, combine 1 & 1/2 cups beef broth with 3 tablespoons whole grain mustard. Add the liquid to the skillet used for searing, turning the heat to medium-high. Scrape up browned bits as the mixture bubbles, then pour it over the corned beef in the crock pot.
Step 3: Add Aromatics
Smash 6 cloves of garlic, peel them, and add to the crock pot. Slice 1 large onion into wedges and toss them in along with about 15-20 whole peppercorns, 8-10 sprigs of fresh thyme, and 2 bay leaves. Sprinkle the spice packet* over everything. Cover with the lid and cook on low for 6-7 hours.
Step 4: Cook the Carrots
Prepare 2 pounds of carrots by peeling them and slicing each into thirds, halving any large pieces lengthwise. Add the carrots on top of the beef, re-cover, and cook for an additional 1-2 hours.
Step 5: Prepare the Cabbage
Slice 1 large head of cabbage in half, remove the stem, and cut into wedges. Melt 1/2 cup butter in a 12-inch skillet over medium-high heat. Add all the cabbage and sprinkle with 1 teaspoon kosher salt. Saute for about 10 minutes until slightly wilted. Add the cabbage on top of the carrots in the crock pot and cook on low for another 30-60 minutes.
Step 6: Serve
To serve, transfer the cooked ingredients to a large platter. Slice the rested beef against the grain, arrange the carrots and drained cabbage beside it, and garnish with chopped parsley or chives. Pair with seasonal autumn harvest sides like roasted sweet potatoes or grilled vegetable skewers for added variety, and serve with homemade horseradish sauce.
Alternative Cooking Methods
