Bloom the yeast in the warm water in the bowl of a stand mixer. Next add the oil and salt and give it a stir. Add the flour in one cup at a time, stirring intermittently until a dough forms and it begins to pull away from the sides.
Remove the dough and knead it on a lightly floured surface until smooth, adding a little more flour as needed until it doesn't stick to your hands. Place the dough in a greased bowl, cover, and let it rest until doubled in size.
Once the dough has doubled in size, preheat the oven to 350°F and place a deep-rimmed skillet or pot on the stove ¾ full of water over high heat. Dissolve the baking soda into the water and bring to a boil.
While the water heats up, shape the pretzels: roll a piece of dough into a string, then take the two ends and twist them around once or twice and fold over and press into the bottom of the pretzel.
Once the water reaches a boil, carefully drop the pretzels in (2-3 at a time) and cook each side for one minute. Remove the pretzels from the water and place on a greased baking sheet. Once the sheet is full, bake the pretzels for 30-40 minutes until the tops become golden brown.
Remove the pretzels from the oven and sprinkle with salt (we also use the slightest amount of oil on the pretzels, which allows the salt to stick). Enjoy!
