Begin the recipe by mixing together in a large bowl the 1 pound ground beef, ½ cup bread crumbs, ¼ cup milk, ½ medium chopped onion, 2 minced garlic cloves, ¼ cup grated Parmesan cheese, 1 large egg, 1 teaspoon salt, and ½ teaspoon ground black pepper. Mix until all of the ingredients are fully combined.
Using your hands or a small cookie scoop, form the meatballs into small bite-size balls. Try to make each meatball about the same size, using a cookie scoop or measuring spoon certainly helps with this.
In a large deep pot over medium-high heat, add the 4 tablespoons of vegetable oil and heat thoroughly. Add half of the meatballs and turn them often on each side to make sure they evenly cook, about 5 to 7 minutes before carefully removing. Continue the process with the rest of the meatballs. If you need to add more oil, you may do so before adding the second batch.
Once finished cooking all of the meatballs, prepare a homemade sauce in the same pan or carefully drain the oil from the pot and add 24 ounces of your favorite jar of sauce. *{Homemade Sauce Recipe} To make a quick pasta sauce, use the same pot and pour in a 28 ounce can of crushed tomatoes, 2 tablespoons tomato paste, 1 tablespoon of minced garlic, 1 tablespoon basil, ½ tablespoon dried oregano, ½ tablespoon dried rosemary, and salt and ground black pepper to taste. Bring the sauce to a low boil on medium heat, then reduce heat, cover and simmer for 10 minutes to allow the flavors to come together.
Add the meatballs to the sauce and simmer on low heat for about 5 to 10 minutes, until the meatballs are heated throughout. Serve with 12 ounces cooked spaghetti pasta and enjoy!
