This is a quick and comforting one-pan meal that turns a regular weeknight into something special. Savory ground beef and tender bowtie pasta are coated in a luxuriously creamy, garlicky Parmesan sauce. The secret to the perfect silky sauce is reserving starchy pasta water.
Do not skip reserving the pasta water; it is essential for the sauce texture. Use freshly grated Parmesan for best melting. Avoid adding cheese to a boiling sauce to prevent it from seizing. Leftovers reheat well with a splash of milk or broth.
