Make Meatballs: In a large bowl, combine 1 pound ground beef, ½ pound ground pork, ¼ cup parmesan cheese, ¼ cup yellow onion (grated), 2 tablespoons breadcrumbs, 2 teaspoons Italian seasoning, 2 teaspoons garlic, 1 large egg, 1 teaspoon kosher salt, ½ teaspoon lemon zest and ¼ teaspoon ground black pepper. Take about 2 tablespoons of the meatball mixture at a time and form into a meatball. Set aside on a plate until all the meatballs are formed.
Smoker: Pour 24 ounces marinara sauce in a 12 inch cast iron skillet. Place meatballs directly on the wire rack and place the cast iron skillet next to them. Close lid and let cook 30-40 minutes or until the meatballs reach an internal temperature of 125-130℉ (use a meat thermometer).
Finish: Transfer meatballs to the sauce and close smoker lid. Let cook in the sauce until they reach an internal temp of 140℉ (or let them simmer longer if you prefer). Remove from smoker and let cool slightly.
Serve: with spaghetti, other noodles of your choice or some creamy parmesan orzo!
