In a mixing bowl, combine warm water, yeast, and sugar. Let sit for 5 minutes until frothy.
Add flour and salt to the yeast mixture. Mix until a dough forms.
Knead the dough on a floured surface for about 5 minutes until smooth.
Place the dough in a greased bowl, cover, and let rise for 1 hour.
Preheat the oven to 450°F (230°C) and line a baking sheet with parchment paper.
Bring a large pot of water to a boil and add baking soda.
Divide the dough into 8 equal pieces and shape each into a pretzel.
Boil each pretzel in the water for 30 seconds, then remove and place on the baking sheet.
Brush each pretzel with beaten egg and sprinkle with coarse salt.
Bake for 12-15 minutes until golden brown. Enjoy warm!
