Ingredients:
- 1 lb ground beef
- 1 lb ground pork
- 1/2 cup Panko breadcrumbs
- 1 large egg, beaten
- 1/4 cup whole milk
- 1 tsp ground allspice
- 1/2 tsp ground nutmeg
- 1 tsp salt
- 1/2 tsp black pepper
- 2 cups beef broth, low sodium
- 1 tbsp Worcestershire sauce
- 2 tbsp all-purpose flour
Instructions:
- Prepare the meat mixture. In a large bowl, combine the ground beef, ground pork, Panko, beaten egg, milk, allspice, nutmeg, salt, and pepper. Mix with your hands until just combined Note: Overmixing makes the meatballs tough.
- Roll the meatballs. Scoop about 1.5 tablespoons of mixture and roll into balls. Ensure they are roughly the same size so they cook evenly.
- Sear the meat. Heat a skillet over medium high heat with a splash of oil. Brown the meatballs until a mahogany colored crust forms on all sides. You aren't cooking them through here, just adding flavor.
- Mix the gravy base. In your slow cooker, whisk together the beef broth, Worcestershire sauce, and all purpose flour until the mixture is completely smooth and no flour clumps remain.
- Combine everything. Carefully add the seared meatballs and all the browned bits (pan drippings) from the skillet into the slow cooker.
- The slow simmer. Cover the pot and cook on High for 4 hours (or Low for 7-8 hours) until the meat is tender.
- Add the dairy. During the last 30 minutes of cooking, stir in the heavy cream, sour cream, and melted butter.
- Final thicken. Stir gently until the sauce is glossy and thick and coats the meatballs beautifully.
