hoursA 3 to 4 lb corned beef flat cooked 8 to 9 hours on LOW, tender at 190 to 205°F, rested and sliced 1/4 inch thick across the grain.
Ingredients
3 to 4 lb corned beef brisket flat
2 bay leaves
1 tbsp whole grain mustard
1 tbsp brown sugar
1 spice packet that came with the brisket
1 large yellow onion, sliced
4 garlic cloves, smashed
2 cups beef broth or water
1 tsp black pepper
1 tbsp apple cider vinegar
1 tbsp Dijon mustard, for serving
Rye bread, for serving
Directions
- Rinse the brisket under cold water and pat it dry so the surface brine does not oversalt the liquid.
- Scatter the onion and garlic in the bottom of the crockpot.
- Set the brisket on top, fat side up.
- Whisk the broth, mustard, brown sugar, vinegar and spice packet together.
- Pour the liquid around the meat so it reaches about halfway up the brisket.
- Add the bay leaves and the pepper.
- Cover and cook on LOW 8 to 9 hours or HIGH 4 to 5 hours without lifting the lid.
- Check the thickest part: it should read 190 to 205°F and a probe should slide in with no resistance.
- Lift the brisket to a board, cover loosely with foil and rest it 15 to 20 minutes.
- Slice 1/4 inch thick across the grain and spoon a little liquid over the slices.
Notes
- Cut across the grain or the slices fall into strings. Do not cook in plain water if you want flavor. Store slices in the liquid.
Why the flat slices cleanly
The flat is leaner and has a uniform shape, so it slices into tidy pieces. Cooking it in broth with onion and mustard puts flavor into the meat, where plain water would only pull flavor out. A rest before slicing keeps the juices from running onto the board.
Aim for 1/4 inch slices, cut across the grain.
Swaps and what fails
Beer or apple juice can replace some of the broth. A little more brown sugar gives a sweeter finish. Do not cut with the grain, or the slices fall into strings.
Serving
Rye bread, grainy mustard and a pile of roasted cabbage make an easy dinner. For sandwiches, layer the slices with Swiss and kraut.
Leftovers
Store the slices in the cooking liquid so they stay moist, and reheat gently, covered.
A sharp slicing knife helps. Cut the flat in half across the grain first if it is long, then slice each piece. Use the leftover liquid as a hot dip on the side.
