Sourdough Garlic Knots

Divide dough into 2 equal pieces and arrange on a parchment-lined baking sheet a few inches apart. Cover loosely with plastic wrap and let stand at room temperature until softened and pliable, about 1 hour.

Working with one piece at a time, use a lightly floured rolling pin to roll dough into a 6-inch square on a lightly floured surface. Cut into six 1-inch strips. Roll one strip to form a rope about 8 inches long, then tie into a single knot. Transfer to the parchment-lined baking sheet. Repeat with remaining strips and second piece of dough, arranging the knots a few inches apart on the baking sheet. Cover loosely with plastic wrap and let stand until puffed and doubled in size, about 2 hours.

Heat oven to 400 degrees. Bake knots until golden on bottom, about 15 minutes.

Meanwhile, in a small saucepan, cook butter and oil over low heat until butter melts. Add garlic and cook, stirring occasionally, until softened and very fragrant, about 5 minutes. Scrape butter mixture into a large bowl, then stir in parsley and season with salt.

In batches, toss the warm knots in the garlic butter until well coated. Sprinkle with Parmesan, if desired, and serve with marinara sauce
