Ingredients
Method
- In a small bowl, combine 0.5 cup plain panko breadcrumbs and 0.25 cup whole milk, letting them sit for 5 minutes until fully absorbed.
- In a large mixing bowl, combine 1 lb ground beef, 1 lb ground pork, the soaked breadcrumbs, 1 beaten egg, 0.5 cup grated yellow onion, 2 minced garlic cloves, 0.5 tsp ground nutmeg, 0.25 tsp ground allspice, 1 tsp salt, and 0.5 tsp black pepper until evenly mixed.
- Shape the meat mixture into 30 meatballs, each about 1.5 inches in diameter, and place them in a single layer at the bottom of a 6-quart slow cooker.
- In a medium bowl, whisk together 2 cups low-sodium beef broth, 1 tbsp Worcestershire sauce, 0.25 cup melted unsalted butter, and 0.25 cup all-purpose flour until completely smooth.
- Pour the broth mixture gently over the meatballs, cover with the lid, and cook on LOW for 4 hours until the meatballs are thoroughly cooked.
- Gently stir 0.5 cup warmed heavy cream and 0.5 cup room-temperature sour cream into the slow cooker sauce during the last 15 minutes of cooking.
- Sprinkle with 2 tbsp finely chopped fresh parsley and serve warm over egg noodles or mashed potatoes.
Notes
Avoid stirring for the first 2 hours so the meatballs firm up and hold their shape.
Shortcut: use 2 pounds of frozen fully cooked meatballs and cook 3 to 4 hours on LOW.
