Toss half a 28-ounce bag frozen crinkle-cut fries with 1 tablespoon olive oil and 1/4 teaspoon each kosher salt, pepper, garlic powder, onion powder and paprika. Spread on a baking sheet and bake at 425˚ until crisp, about 30 minutes. Heat 1/2 cup half-and-half in a saucepan over medium heat until steaming; add 4 ounces diced sharp cheddar cheese and 2 diced slices American cheese. Cook, whisking, until smooth. Whisk in 1/2 teaspoon Worcestershire sauce. Season with salt and pepper. Serve with the fries.
