- 1 teaspoon onion powder – complements garlic with sweet, savory notes
- Salt and pepper to taste – balances and enhances all flavors
- 1 tablespoon olive oil – for browning and developing flavor
For the Mushroom Gravy:
- 1 cup beef broth – creates rich, savory gravy base

Step-by-Step Instructions
Form the Perfect Meatballs
In a large mixing bowl, combine ground beef, breadcrumbs, Parmesan cheese, chopped parsley, egg, garlic powder, onion powder, salt, and pepper. Mix gently with your hands until just combined—overmixing will result in tough meatballs. Roll mixture into 1-inch diameter balls, yielding approximately 20-24 meatballs.
Brown for Maximum Flavor
Heat olive oil in a large skillet over medium heat. Brown meatballs on all sides, about 5-7 minutes total. This crucial step develops a caramelized exterior that adds significant flavor to the finished dish. Don’t worry about cooking them through—they’ll finish in the slow cooker. Transfer browned meatballs to your slow cooker.
Build the Mushroom Gravy
In the same skillet with the flavorful browned bits, add sliced mushrooms and sauté for 3-4 minutes until tender and lightly browned. Pour in beef broth, scraping up any browned bits from the bottom of the pan. Stir in onion soup mix and Worcestershire sauce, bringing the mixture to a gentle simmer for 2 minutes.
Slow Cook to Perfection
Pour the mushroom gravy mixture over the meatballs in the slow cooker, ensuring meatballs are mostly covered. Cover and cook on low for 6-8 hours or high for 3-4 hours. The meatballs should be cooked through and tender, while the gravy develops rich, complex flavors.
Thicken if Desired
During the last 30 minutes of cooking, if you prefer thicker gravy, mix cornstarch with 2 tablespoons cold water to create a slurry. Stir into the slow cooker and continue cooking until the gravy reaches your preferred consistency.
Serve and Enjoy
Taste and adjust seasoning as needed. Serve hot over mashed potatoes, egg noodles, or rice, spooning the rich gravy generously over each portion.
