- 14 cups minced oyster mushrooms
- 9 cups panko bread crumbs
- 1/4 cup minced garlic
- 3 tablespoons ground black pepper
- 3 tablespoons kosher salt
- 5 pounds ground Kobe beef, at room temperature
- 3 tablespoons dried parsley
- Preheat oven to 350 degrees F (175 degrees C). Line 3 baking sheets with parchment paper.
- Mix oyster mushrooms, panko, garlic, black pepper, and salt together in a large bowl with your hands. Mix in ground beef until mixture is sticky and thoroughly combined.
- Scoop beef mixture with an ice cream scoop and roll lightly into balls. Place on the lined baking sheets.
- Bake in the preheated oven until browned and an instant-read thermometer inserted into the center reads 165 degrees F (74 degrees C), about 20 minutes. Remove from oven and let stand for 10 minutes before serving.
- Grind dried parsley into a fine dust using a coffee or spice grinder. Garnish meatballs with parsley dust.
