In a large skillet over medium heat, fry the meatballs in the vegetable oil until golden brown on all sides. You will need to do this in batches, do not crowd to pan. Place the meatballs on a paper-towel lined plate to drain any excess oil.
2 tablespoons vegetable oil for frying
Place the browned meatballs in the slow cooker.
Whisk together the beef stock, Worcestershire sauce, dijon, salt, and pepper in a small bowl.
Pour the sauce over the meatballs. Cook on low for 4-6 hours or high 2-3 hours, until meatballs are cooked through or until the desired tenderness is reached.
Take meatballs out and set them aside.
Add the sour cream and heavy cream directly to the slow cooker, whisk to combine. In a small bowl mix together the cornstarch and water. Whisk the cornstarch slurry into the sauce. Cook on high uncovered for 15 minutes until thickened. Taste, adjust seasoning if necessary.
