Ingredients
Corned Beef
- 3 lb. flat cut corned beef roast (ditch the spice packet)
- 2 tsp. cooking oil
Maple Mustard Sauce
- ½ cup maple syrup
- ¼ cup yellow mustard
- ¼ tsp. black pepper
- 2 garlic cloves (minced)
Instructions
- Prepare the Corned Beef: Rinse the corned beef roast under cold water to remove excess brine and pat it dry thoroughly with paper towels to ensure good browning.
- Brown the Meat: Heat a large skillet over medium-high heat and add cooking oil to coat the bottom. When the oil is hot, sear the corned beef on all sides until it develops a deep golden-brown crust, which adds flavor and texture.
- Transfer to Slow Cooker: Place the browned corned beef roast into the slow cooker, ensuring it sits evenly.
- Make the Maple Mustard Sauce: In a small bowl, combine the maple syrup, yellow mustard, freshly ground black pepper, and minced garlic cloves. Mix thoroughly to create a uniform sauce.
- Coat and Cook: Pour the maple mustard sauce evenly over the corned beef in the slow cooker. Cover with the lid securely.
- Slow Cook: Cook on the LOW setting for 7 hours without lifting the lid to maintain heat and moisture, allowing the flavors to meld and the meat to become tender.
- Serve: Once cooking is complete, remove the corned beef and slice as desired. Serve with your favorite sides such as mashed red potatoes, steamed carrots, and cabbage for a comforting meal.

- Discard the spice packet that comes with the corned beef to avoid overpowering the maple-mustard flavors.
- Browning the meat before slow cooking enhances flavor; do not skip this step.
- Do not open the slow cooker lid during cooking to retain heat and moisture for best tenderness.
