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 under cold water to remove any excess brine, then pat it dry thoroughly with paper towels to ensure proper browning.
- Brown the Meat: Heat a large skillet over medium-high heat and add the cooking oil, coating the bottom of the pan evenly. Once hot, sear the corned beef on all sides until it develops a deep brown crust, which helps enhance flavor and texture.
- Transfer to Slow Cooker: Place the browned corned beef roast into the slow cooker, setting the stage for a slow, tender cooking process.
- Make the Sauce: In a small bowl, whisk together the maple syrup, yellow mustard, black pepper, and minced garlic cloves until well combined. Pour this sauce evenly over the corned beef in the slow cooker.
- Slow Cook: Cover the slow cooker with its lid and cook on the LOW setting for 7 hours. Avoid opening the lid during this time to maintain consistent heat and moisture, ensuring the meat becomes tender and infused with the sauce flavors.
- Serve: Once cooked, slice the corned beef against the grain and serve it with your choice of sides. Suggested sides include mashed red potatoes, steamed carrots, and cabbage for a classic and hearty meal.
Notes
- Remember to brown the corned beef first to lock in flavor and create a delicious crust.
- Do not use the spice packet that typically comes with corned beef, as the maple mustard sauce provides all necessary seasoning.
- Slow cooking on LOW heat is crucial for tender results; do not rush by cooking on HIGH.
- Let the meat rest a few minutes before slicing to retain juices.
- Pair with traditional sides like mashed potatoes and steamed vegetables for a complete meal.
