In a small bowl add the cold water and corn starch, whisk with a fork until smooth. Add to the slow cooker along with the broth. Mix the broth with the cornstarch slurry.
Add meatballs to the bottom of the slow cooker.
Top with cream of mushroom soup, brown gravy mix, Worcestershire sauce, dried parsley, garlic powder, and onion powder. Stir well to mix all ingredients. It's ok if the cream of mushrooms doesn't dissolve, it will melt with the cooking time.
Place the lid on the slow cooker and cook on high for 3 hours or low for 5 hours. Stir occasionally towards the end of the cooking time.
When cooking time is complete, add the sour cream and stir. Serve the meatballs and gravy over large egg noodles or rice.

Notes
How to store?Meatballs will last in the fridge for about four days or in the freezer for three months.How to reheat?The quickest way to reheat a small serving of these meatballs is in the microwave. You can also reheat it on the stovetop in a saucepan.Variations
Use a can of golden mushroom soup instead of cream of mushroom for a richer, deeper flavor.
Stir in ½ cup of shredded Swiss or Parmesan cheese before serving for an extra creamy, savory sauce.
Use greek yogurt instead of sour cream for a healthier dish.
Add sliced mushrooms or small can of mushrooms.
My Serving Suggestions:
Serve as an appetizer with toothpicks and small plates.
Wide egg noodles are the most poplular choice with Swedish meatballs, don't mix them into the slow cooker, let each guest choose how much noodles and meatballs they want.
Crockpot Mashed Potatoes are a great side dish for anything with gravy!
Rice is one of my favorite ways to serve this. It soaks up more gravy than any of the other options.
Great served with chopped fresh dill on any way you serve them.
