How to Make Slow Cooker Corned Beef and Cabbage

Let’s get this party started—the hardest part is slicing the veggies.

1. Prep the Brisket

Place the brisket flat in your slow cooker, fat side down (this keeps the seasoning on top for flavor).

2. Add the Seasonings

Mix together the mustard, coriander, dill, red pepper flakes, black pepper, and salt. Rub this seasoning blend all over the top of the brisket.

4. Cook Low and Slow

Cover and cook on low for 6–8 hours or high for 3–4 hours. You’re aiming for an internal beef temperature of at least 190°F for the juiciest, tender results.

5. Rest, Slice, and Serve

Take the brisket out and let it rest for 15 minutes (this helps the juices redistribute). Slice thinly against the grain for the most tender pieces. Serve with veggies and a ladle of cooking juices.

Tips for Next-Level Slow Cooker Corned Beef

No liquid needed: The brisket and veggies release enough moisture as they cook.
Trim fat after cooking: For prettier slices, cut away extra fat before serving.
Don’t skip the rest: Letting the meat rest before slicing keeps it juicy.
Customize the seasoning: Make it your own—add extra pepper for a little more zing or toss in a bay leaf.

Storing, Freezing & Leftovers

Fridge: Store meat and veggies separately in airtight containers for up to 3 days.
Freezer: Slice and freeze leftover beef (veggies get mushy after freezing). Beef keeps up to 3 months—defrost in the fridge.
Reheat: Warm gently in the microwave or in a pan with a splash of broth or water.

Leftover ideas:

Layer in sandwiches (Reubens, anyone?), pile into wraps, or chop for a breakfast hash with eggs.

Serving Suggestions

Classic: Serve as a one-pot meal—no sides required!
Potato swap: Make mashed potatoes separately and spoon the cooking juices over top.
Bread: Add a warm dinner roll or slice of crusty bread to soak up all those tasty juices.
Greens: Pair with roasted asparagus or a fresh Caesar salad for a pop of color.
