Preheat oven to 275 degrees Fahrenheit and line a baking sheet with parchment paper.
In a mixing bowl, combine the canola oil, maple syrup, sesame seeds, smoked paprika, salt, cumin, ground ginger, cayenne pepper, and ground mustard. Stir well.
In a separate bowl, combine the oats, cashews, and pumpkin seeds.
Pour the seasoned oil over the oat mix and stir to fully coat the oats.
Evenly space the coated oats over the parchment-lined baking sheet (you may need more than 1 baking sheet), then place the baking sheets in the oven.
Bake the granola for 1 hour, flipping the oats every 10 to 15 minutes to allow for even browning.
Remove the granola from the oven and place on paper towels for 5 to 10 minutes to remove any excess oil.
Eat immediately or store in an airtight container for future use.
