1. In a large pot or skillet over medium-high heat, brown ground beef with onion and garlic. Cook until cooked through and no longer pink. Drain excess grease. Then return to medium heat in the same pot.
3. Reduce to a simmer and cook for about 15 minutes, stirring occasionally until the pasta is tender and has absorbed most of the cooking liquid. Different brands of pasta will have different cook times. If your liquid is evaporating before your pasta is cooked, turn down the heat slightly and add ¼ cup more water, as needed.
