Preheat your oven to 425°F (220°C).
Wash and peel the russet potatoes. Cut them into thick fries, approximately 1/4 to 1/2 inch wide.
Rinse the cut fries under cold water to remove excess starch. Pat them dry with a paper towel.
Heat vegetable oil in a large saucepan or deep fryer to around 350°F (175°C). Carefully add the fries and cook them in batches until golden brown and crispy. Take out fries from saucepan and let them dry on paper towels. Season with salt to taste.
While the fries are cooking, prepare the Voodoo Sauce. In a mixing bowl, combine the mayonnaise, ketchup, Worcestershire sauce, hot sauce, garlic powder, smoked paprika, onion powder, dried thyme, dried oregano, cayenne pepper, salt, and black pepper. Whisk or stir until well combined.
Transfer the cooked fries to a baking sheet and spread them out evenly. Drizzle the Voodoo Sauce over the fries, ensuring each fry is coated.
Place the baking sheet in the preheated oven for about 5 minutes or until the sauce is warm and slightly bubbly.
When you're finished, take the fries out of the oven and let them cool for a little while before you serve them.
