Creating Louisiana Voodoo Fries is both fun and straightforward. Follow these steps for a dish that’s sure to amaze:

1. Prep the Potatoes: Wash and peel the russet potatoes. Cut them into fries, ensuring they are roughly the same size for even cooking.
2. Soak the Fries: Place the cut fries in a bowl of cold water. Let them soak for at least 30 minutes to remove excess starch, resulting in crispier fries.
3. Drain and Dry: After soaking, drain the fries and pat them dry using a clean kitchen towel. This is essential for achieving maximum crispiness.
4. Preheat Oil: In a large pot or deep fryer, heat cooking oil to 350°F (175°C). This temperature is ideal for frying.
5. Season the Potatoes: Toss the dried fries in a bowl with olive oil, Cajun seasoning, salt, and pepper, ensuring they are well coated.
6. Fry the Fries: Fry the seasoned potatoes in batches, being careful not to overcrowd the pot. Cook until golden brown and crispy, about 5-7 minutes per batch.
7. Drain Excess Oil: Once fried, remove the fries from the oil and place them on a paper towel-lined plate to drain any excess oil.
8. Add Cheese: While the fries are still hot, sprinkle the shredded cheddar and Monterey Jack cheese over the top. Allow the heat from the fries to melt the cheese.
9. Top it Off: Drizzle the spicy ranch dressing over the cheese-covered fries. Add diced jalapeños if you’re looking for an extra kick.
10. Garnish: Finish with a sprinkle of sliced green onions for freshness and color.

These simple steps will guide you in creating the most incredible Louisiana Voodoo Fries your friends and family will ever taste!
