Decide how you’re using pumpkin seed oil: finishing/drizzling (keep flavor oils) vs baking/cooking (use more heat-tolerant swaps).
Match flavor intensity: for a nutty, toasted vibe, choose walnut oil; for a bolder aroma, choose toasted sesame oil using slightly less.
Use the listed ratio: if the substitute is stronger (sesame), start lower and adjust after tasting.
If you’re swapping with a neutral oil, add a pinch of crushed roasted pumpkin seeds (start tiny) to restore the “toasted” notes.
For best results, add finishing oils at the end and avoid high heat with delicate oils like flaxseed oil.
