• 3 cups uncooked small macaroni
• 1/2 tablespoon unsalted butter
• 1 small onion, finely chopped

1. Bring a large pot of salted water to a boil and stir in macaroni. Cook, stirring occasionally, until pasta is al dente. Drain in a colander and shake well.
2. While pasta is cooking, melt butter in a large saucepan over medium heat, add onion and cook, stirring, until softened, about 6 minutes. Stir together milk and cornstarch in a large cup; whisk into pot with onion and cook, whisking, until boiling. Continue to cook, whisking, until thickened, about 2 minutes. Stir in peas and salt.
