Ingredients

  • 1 ½ to 1 ¾ lbs russet potatoes peeled and thinly sliced
  • 1 yellow onion thinly sliced
  • ¼ C + 1 tablespoon salted vegan butter divided
  • 1 C raw cashews soaked for 20 minutes in hot water
  • 1 ½ C + ½ C hot water divided
  • 2 teaspoon vegan chicken-flavored bouillon paste
  • 2 teaspoon white wine vinegar
  • 1 tablespoon nutritional yeast
  • ½ teaspoon sea salt
  • ½ teaspoon ground black pepper
  • 3 garlic cloves, minced
  • 1 tablespoon fresh thyme tender stems and leaves finely chopped

Instructions

  • In a large oven safe skillet over medium-high heat, melt ¼ cup of vegan butter. Toss in onions and a pinch of salt, coating the onions in butter. Then continue to cook, only tossing occasionally to caramelize. Total cook time is about 30 minutes or until evenly golden brown and caramelized. Lower heat as needed to prevent burning.
  • Meanwhile you can make the sauce. Drain the cashews from the soaking water, and add to a high powered blender with 1 ½ cups of hot water, bouillon paste, white wine vinegar, nutritional yeast, sea salt, and ground pepper. Blend until very very smooth and set aside.
  • Preheat oven to 400°F close to when the onions are nearly done.
  • Remove the caramelized onions onto a plate and set aside. Add 1 tablespoon of vegan butter, minced garlic, and thyme to the pan and sauté about 1 to 2 minutes until fragrant. Lower the heat on the pan, if needed, to prevent garlic from burning. Add sliced potatoes in thirds, and toss in the mixture to coat evenly. Once all the potatoes are in the pan add ½ cup of hot water and a lid to the pan. Cook 5 to 6 minutes. Remove lid, add in the cashew cream, gently toss the potatoes in the sauce and arrange in an even layer. Turn off the heat. Add caramelized onions on top in an even layer. I found it easiest to use my fingers to place them on top.
  • Place the entire skillet in the oven and bake for 30 minutes. If you decide to transfer the scalloped potatoes in a glass casserole dish for baking, as opposed to a cast iron pan or other metal oven safe skillet, it will take over double the time to bake until the potatoes are soft enough. So bake anywhere from 50 to 70 minutes. I would also maybe add the caramelized onions on top half way through the bake time in this case.
