How to Make Slow Cooker Corned Beef
- Prep the brisket: Place the 3-pound brisket flat in your slow cooker, creating a cozy bed for it.
- Season it up: In a small bowl, mix together the 1 tablespoon dried ground mustard, 1 teaspoon dried ground coriander, 1 teaspoon dried dill, 1 teaspoon crushed red pepper flakes, 1 teaspoon black pepper, and 1 teaspoon kosher salt. Rub this flavorful mixture thoroughly over the top of the brisket.
- Add the veg: Scatter the roughly chopped 1 small onion, the 4 cut carrots, and the 6 oz of red baby potatoes around the brisket in the slow cooker.
- Set it to cook: Cover and cook on high for 3-4 hours or on low for 6-8 hours, depending on how much time you have. The longer it cooks, the more tender the meat will become.
- Slice and serve: Once done, remove the brisket from the slow cooker and let it rest for about 15 minutes. This step is crucial for maintaining juiciness. Slice thinly against the grain and serve it with the veggies.
Storing & Reheating
Once the Slow Cooker Corned Beef has cooled, you can store any leftovers in an airtight container. It’ll keep in the refrigerator for up to 3-4 days. If you want to extend its life, consider freezing it; properly stored, the frozen corned beef can last up to 3 months. When you’re ready to enjoy it again, simply thaw it overnight in the refrigerator and reheat gently in the microwave or oven until warmed through. Keep in mind that the texture may change slightly, but a splash of broth or water during reheating will refresh it.
Chef’s Helpful Tips
- Watch the seasoning: Don’t be tempted to skip the salt; it’s crucial for enhancing flavors. Adjust according to taste, especially if using low-sodium broth.
- Slicing tip: Always slice against the grain to ensure each piece is tender and easy to chew.
- Veggie swap: Feel free to swap in your favorite root vegetables, like parsnips or turnips, for a unique twist.
- Cooking time: If you prefer a bit more firmness to your vegetables, add them halfway through the cooking process.
- Make-ahead magic: Prepare the seasoning and chop veggies the night before for a quick assembly in the morning.
