Season your short ribs with the garlic salt, onion powder and black pepper.
In a large skillet over medium high heat melt the butter and sear the short ribs quickly. Just enough to get color not to cook through.
To the bottom of the slow cooker add onion, carrots, celery and garlic cloves.
Place the short ribs on top of the vegetables.
Whisk together the cranberry juice, beef stock, wine, bouillon, dijon mustard and worchestershire sauce.
Pour the sauce over the short ribs.
Add in the rosemary and cranberries.
Cover and cook on low for 6-8 hours or high 4-6 hours until tender.
Garnish with cranberries and parsley.
Serve!
