3 lbs corned beef any visible fat removed (I use Rachel's)
1 ½ tsps vegetable oil
2 cloves garlic minced
2 large yellow onions sliced
2 large carrots cut into 2 inch lengths
3 celery stocks cut into 2 inch lengths
1 ½ cups beef broth
11 oz Guinness beer
3 tablespoon tomato paste (can use Ketchup)
1 tablespoon balsamic vinegar
2 tablespoon corn starch
½ teaspoon salt
1 teaspoon black pepper
½ teaspoon dried thyme
½ teaspoon dried rosemary (or sub 1 teaspoon Italian spices for both Thyme and Rosemary)

Rinse your corned beef ito remove the spices and marinade. Heat oil to medium high in a skillet. Brown corned beef on all sides, about 3 minutes per side.
Put onions, celery, carrots in bottom of slow cooker. Add the browned corned beef.
In a measuring cup, mix the stock, tomato paste, vinegar, garlic and other spices. Pour over the corned beef and vegetables. Pour the Guinness over the top of everything.
Cook on low 7-8 hours. During the last hour mix the cornstarch with a few tablespoons of the sauce and shake well in a small covered jar. Pour the slurry back into the slow cooker and allow the gravy to thicken.
Remove corned beef from the slow cooker and loosely cover with foil for about 10 minutes before slicing. Serve with the sauce and vegetables.
