Preheat oven to 250 degrees F. In a small bowl, combine the canola oil, Ranch mix, dried dill, garlic powder and cayenne pepper together until fully combined.
Place the crackers in a gallon size resealable bag and pour on the ranch mixture. Seal, then shake to coat the crackers with the mixture.
Spread the crackers on a baking sheet and bake for 15-20 minutes or until golden, then set aside to cool.
