Louisiana Voodoo Fries

Over high heat, bring a large pot of water to a rolling boil. Blanch the fries in boiling water for two to three minutes, then drain and pat dry if using fresh-cut fries.
Fry fresh-cut potatoes in heated oil at 350°F until golden and crispy, or cook frozen fries as directed on the package. After draining on paper towels, sprinkle with salt.
Melt 1 tablespoon of butter in a small saucepan over low heat. Add 1 tablespoon of flour and simmer until smooth, about 1 minute.
Add ½ cup of milk gradually while whisking and swirling until the liquid thickens.
Stir in 1 cup of the shredded cheddar cheese until it melts and becomes creamy. Add a little milk if necessary to get the right consistency. Take off the heat.
Combine 1 teaspoon hot sauce, 1 teaspoon Cajun seasoning, and ¼ cup ranch dressing in a small bowl and stir until thoroughly blended. Put aside.
Drizzle the homemade cheese sauce over the cooked fries after placing them on a serving plate.
Evenly distribute the bacon crumbles on top.
If desired, top with chopped green onions and drizzle with the hot ranch mixture.
Serve hot and crispy right away.
