In a large skillet or Dutch oven over medium-high heat, cook the ground beef with the chopped onion for 5–7 minutes, breaking up the meat as it browns. Continue until beef is cooked through and onion is softened. Drain excess fat if needed.

Add pasta shells, ensuring they are fully submerged in the liquid. Increase heat and bring to a boil, then reduce to low and cover. Simmer for 10–12 minutes, stirring occasionally, until pasta is al dente and most liquid is absorbed.
