Begin by bringing a large pot of salted water to a rolling boil. Once boiling, add the bowtie pasta and cook according to package instructions, typically around 8-10 minutes, until the pasta is al dente.

Carefully drain the pasta in a colander, allowing excess water to escape. Rinse the pasta under cold running water to stop the cooking process. Let it cool completely before moving on to combine with other ingredients.

In a large mixing bowl, add the cooled bowtie pasta, diced red onion, diced Canadian bacon, and frozen peas. Fold these ingredients together with a spatula.

In a separate bowl, combine sour cream and French dressing, mixing until smooth. Taste and add salt and pepper to season.

Pour the creamy dressing over the pasta mixture, gently folding until all components are coated.

Sprinkle in the shredded cheddar cheese, folding it into the mixture. Cover with plastic wrap and refrigerate for at least 2 hours before serving.
