In a large mixing bowl, combine the water, active dry yeast, and granulated sugar. Let it sit for 4-5 minutes until the mixture foams up. This means your yeast is active. If it does not foam up, restart again and make sure that your water is not too warm. It needs to be between 95-105*F.
Add the garlic salt and olive oil, then mix well.
Add the flour, one cup at a time until it's fully incorporated and a ball starts to form.
Transfer the dough to a lightly floured surface and knead the dough until you have a ball and all the dry flour is fully incorporated.
Transfer the dough to an oiled mixing bowl and let it rise, cover it for 1 hour.
Put the dough on a working surface such as a baking mat. Roll the dough into a log and this will make it easier to separate into 12 pieces, do so.
Roll each piece into a 10-inch rope about 1/2 inch thick.
Fold to make a knot, think of a square knot when tying your shoes.
In a small bowl, melt 1 tbsp of butter.
Brush butter onto the knot.
Place in the air fryer and air fry or air crisp for the Ninja Foodi at 370*F for 6 minutes until nice and golden. You can use parchment paper or silicone liners for the basket of the air fryer.
While it is cooking, melt 2 Tbsp of butter and mix in the garlic powder.
Once done, carefully remove and place on a cooling rack.
Brush with the garlic butter and then sprinkle with parsley and grated Parmigiano.
Repeat the process for the remaining knots until you have cooked them all.
