In a medium bowl, combine the instant yeast, sugar, and warm water. Let it sit for about 5 minutes until foamy.
In a large mixing bowl, whisk together the flour and salt. Once the yeast mixture is ready, pour it into the flour mixture along with 1 tablespoon of olive oil.
Stir with a wooden spoon until a dough forms. Transfer the dough to a floured surface and knead for about 5-7 minutes until smooth and elastic. Add more flour as needed to prevent sticking.
Form the dough into a ball and place it in a lightly greased bowl. Cover with a damp cloth and let it rise in a warm place for about 1 hour or until doubled in size.
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Once the dough has risen, punch it down and divide it into 8 equal pieces. Roll each piece into a rope about 6 inches long. Tie each rope into a knot and tuck the ends underneath. Place them on the prepared baking sheet.
In a small bowl, mix together the minced garlic, remaining 2 tablespoons of olive oil, red pepper flakes, and chopped parsley. Brush this mixture generously over each knot.
Sprinkle Parmesan cheese over the knots if desired.
Bake for 12-15 minutes or until the knots are golden brown and cooked through.
Allow the knots to cool for a few minutes before serving.
Notes
Serve warm in a breadbasket lined with a kitchen cloth, garnished with additional parsley for a pop of color. Drizzle with leftover garlic oil for an enticing finish.
