- Adding a few whole cloves or bay leaves to the slow cooker can infuse additional aromatic flavors.

FAQs
Can I use a different cut of corned beef?
While flat cut is preferred for its uniform shape and tenderness, you can use point cut corned beef; just expect a bit more fat and a longer cooking time.
Is it necessary to brown the meat before slow cooking?
Browning the beef adds extra flavor and color, but if you’re short on time, you can skip this step and still get good results in the slow cooker.

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 salt from the curing process. Pat it dry thoroughly with paper towels to ensure it browns properly in the pan.
- Brown the Meat: Heat a large skillet over medium-high heat and add 2 teaspoons of cooking oil, swirling to coat. Once hot, sear the corned beef on all sides until a rich, brown crust forms, about 3-4 minutes per side. This step locks in flavor and adds depth.
- Transfer to Slow Cooker: Place the browned corned beef roast into the slow cooker, positioning it evenly.
- Make the Maple Mustard Sauce: In a small bowl, whisk together ½ cup maple syrup, ¼ cup yellow mustard, ¼ teaspoon black pepper, and minced garlic cloves. Ensure the sauce is well combined for a balanced sweet and tangy flavor.
- Apply Sauce and Cook: Pour the maple mustard sauce evenly over the corned beef in the slow cooker. Cover with the lid securely and cook on LOW heat for 7 hours. Do not open the lid during cooking to maintain heat and moisture for tender results.
- Serve: After cooking, remove the corned beef and let it rest briefly before slicing. Serve warm with traditional sides such as mashed red potatoes, steamed carrots, and cabbage for a complete meal.
Notes
- For best results, avoid using the spice packet that comes with the corned beef to better control flavor.
- Do not open the slow cooker lid during cooking; this helps retain heat and cooking time efficiency.
- Make sure to properly brown the meat before slow cooking to enhance the flavor.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
