Place oats, pumpkin seeds, sunflower seeds, coconut, pecans, syrup, olive oil, sugar, and 1 teaspoon salt in a large bowl and mix until well combined. Spread granola mixture in an even layer on a rimmed baking sheet. Transfer to oven and bake, stirring every 10 to 15 minutes, until granola is toasted, about 45 minutes.
Remove granola from oven and season with more salt to taste. Let cool completely before serving or storing in an airtight container for up to 1 month.
