Activate the yeast.
In a large bowl, combine the warm water and yeast. Let stand for 5–10 minutes, until foamy.
Make the dough.
Add the salt and flour. Mix by hand or with a stand mixer fitted with a dough hook for about 2 minutes.
Add 1 tablespoon olive oil and continue kneading until the dough is smooth and elastic, about 5–7 minutes more. The dough should feel soft and slightly tacky.
Let rise.
Lightly grease the bowl and turn the dough to coat. Cover and let rise in a warm place for about 1 hour, or until doubled in size. Allow extra time if your kitchen is cool.
Shape the knots.
Gently press down the risen dough and divide into equal small portions.
Roll each portion into a rope long enough to tie into a loose knot. Tuck the ends underneath if desired.
Let rise again.
Arrange the knots on a baking tray lined with parchment paper rated for 450°F, leaving space between them. Cover and let rise for about 20 minutes, until puffy.
Bake.
Meanwhile, preheat the oven to 450°F.
Bake for 15–18 minutes, or until golden brown and cooked through. Begin checking earlier if your knots are small.
Prepare the garlic topping.
Mix the olive oil or melted butter with the finely chopped garlic, parsley, and optional Italian seasoning.
Brush and serve.
Generously brush the hot knots with the garlic mixture as soon as they come out of the oven.
Let cool slightly, then serve warm.
