Dissolve yeast and sugar in warm water, about five minutes.
Add flour and salt then knead lightly for 2 minutes with a mixer or by hand.
Let dough rest for 10 minutes.
Melt butter in a 9x13 pan.
Divide dough into 18 parts. Roll into snakes and put close together in pan with melted butter.
Preheat oven to 375 degrees.
Let dough rise in pan for 20 minutes.
Sprinkle with grated parmesan cheese and garlic salt until they're all covered.
Bake at 375 degrees for 20 minutes.
Serve warm directly from the pan or on a serving tray, all breadsticks together.
Don't leave space between snakes in the baking dish. You want them to be tightly packed in there with a little space around the sides of the dish so the breadsticks can rise and fill up the rest of the space.Double the parmesan cheese if you like really cheesy breadsticks. I don't recommend doubling the garlic salt because they'll get really salty but adding a little more cheese never hurt anyone.Use a high-quality butter like Kerrygold for the best taste. These are baked in butter so the taste of the butter does matter. You can make them with whatever butter you have on hand but the good stuff is better.Make two batches of these breadsticks, they'll go fast.
