How to Make It
Bring 1 1/2 cups water and broth to a simmer in a large saucepan (do not boil). Keep warm over low heat.
Heat the oil in a Dutch oven over medium heat. Add onion; cook 8 minutes or until golden, stirring frequently. Add 1/2 cup water, squash, salt, and pepper; cook 10 minutes or until squash is tender and water has almost evaporated. Add rice; stir until combined. Stir in 1/2 cup broth mixture; cook until liquid is nearly absorbed, stirring constantly. Add the remaining broth mixture, 1/2 cup at a time, stirring constantly until each portion of broth is absorbed before adding the next (about 30 minutes total). Stir in cheese, butter, and parsley. Serve immediately.
