Preheat your oven to 300°F (149°C) to ensure even roasting.

Rinse the raw pumpkin seeds under cold water and pat them dry.

Combine melted butter and Worcestershire sauce, then mix in the pumpkin seeds, Cajun seasoning, paprika, and salt.

Spread the seasoned pumpkin seeds in a single layer on a baking sheet.

Roast the seeds in the oven for 45 to 60 minutes, stirring every 20 minutes.

Check for crunchiness at 45 minutes and continue roasting if necessary.

Let the seeds cool for about 10 minutes before serving.
