Step One
Begin by preheating the oven to 450 degrees Fahrenheit.
Next, mist a baking sheet with olive oil (using a Misto) or nonstick cooking spray.
Step Two
In a large bowl, combine the ground beef, egg, breadcrumbs, and oregano. Mix with your hands until well combined and shape into 16 meatballs (about 1 ½ inches in diameter each).
Step Three
Next, place the meatballs on your baking sheet and bake for 12-15 minutes. While not totally necessary (meaning, I’ve forgotten to do this, and they turn out just fine), I like to take the meatballs out of the oven after about 6 minutes and flip them, so they brown evenly.
While the meatballs are baking, boil your water and cook the spaghetti noodles according to the package directions.
Step Four
Place the spaghetti sauce in a large pot and, when the meatballs are done baking, add them to the pan. Heat the sauce and meatballs over medium heat for 5-10 minutes.
(You’ll know it’s done when the sauce is heated, and the meatballs begin to absorb some of the sauce. For good measure, I always like to stick my digital thermometer into the middle of a meatball to make sure it’s at least 165 degrees Fahrenheit because, well, salmonella freaks me out a bit.)
To serve, place the spaghetti noodles on your plate and top with the meatballs and sauce.
