To bake pumpkin seeds, there are different methods and temperatures you can use. Here are some options:

• 350°F (177ºC) for 12-15 minutes: Toss the seeds every 5 minutes to ensure even roasting.
• 300°F (150°C) for 20-30 minutes: Toss the seeds in melted butter and salt before baking.
• 350°F (177°C) for 20-30 minutes: Boil the seeds in salted water for 10 minutes before drying and roasting. This method can help solve the chewiness problem.
• 325°F (162°C) for 45 minutes: Drizzle the seeds with oil, salt, and seasonings before baking. Stir occasionally and finish baking at a higher temperature (such as 325°F to 375°F) to achieve crispy seeds.

Regardless of the method you choose, its important to clean the seeds thoroughly and dry them before baking to ensure they crisp up properly. You can also experiment with different seasonings, such as cinnamon and sugar, olive oil, pepper, and Worcestershire sauce.
