In large bowl, mix sausage, beef, bread crumbs, onion, garlic and egg until well combined. Shape mixture into 24 (1 inch) meatballs.
In Dutch oven, heat oil over medium heat. Add meatballs; cook 9 to 11 minutes, gently turning occasionally, just until browned on all sides.
Stir in broth, pasta sauce and whipping cream; heat to boiling. Stir in pasta; return to boiling. Reduce heat; simmer uncovered 18 to 22 minutes, stirring occasionally, until meatballs are thoroughly cooked (165°F), pasta is cooked to desired tenderness and sauce is thickened. Top with Parmesan cheese and basil.
