In a mixing bowl or the bowl of a stand mixer, mix together the warm water, salt, and sugar. Add the yeast, and let rest for 5 minutes until yeast starts to foam.
Add flour and oil to the bowl and mix well to form a dough. Turn the dough out on a lightly floured surface and knead for 3-5 minutes to form a smooth dough.
Put the dough back in the bowl and cover with plastic wrap to rest in a warm place for at least 10 minutes, up to 1 hour.
Preheat oven to 450°F (230°C).
Cut dough into 8 pieces. Roll each into a thin rope about 20 inches long. Bring the two ends together to form a circle, then twist the ends together once. Fold the twisted ends up over the top of the circle to form a pretzel shape.
Bring a large pot of water to a boil. Add baking soda. Boil each pretzel for 30 seconds per side.
Transfer pretzels to a wire rack and brush the tops with the egg wash, then sprinkle with salt.
Bake for 10-15 minutes, until golden brown.
