4. Stir in onion; cook for 5 minutes, until onions are translucent and begin to brown. Add garlic, stir for about a minute.
5. Stir in 1 1/2 tablespoons flour; cook and stir for about 1 minute. Add tomato paste, and cook for another minute.
6. Slowly add chicken stock, stir to combine, and return to a simmer. Remove skillet from the heat.
7. Place carrots and celery in the slow cooker. Place roast over the vegetables and pour in any accumulated juices. Add rosemary and thyme.
8. Pour onion and mushroom mixture over the top of the roast. Cover slow cooker, turn to high and cook the roast for 5-6 hours, until the meat is fork tender.
9. Skim off any fat from the surface and remove the bones. Season with salt and pepper to taste.
