Key Ingredients

  • Lemon — We’ll use both the zest and the juice of the lemon.
  • Oats — I used rolled oats for this recipe, but you can substitute instant oats.
  • Chia — We’ll add some ground chia seeds to create a thicker texture. You can use whole chia seeds; I just prefer ground because it creates a smoother finished texture.
  • Syrup — I used maple syrup, but you can substitute agave nectar.
  • Milk — We’ll use almond milk for the best overnight oats! Substitute your favorite plant-based milk.
  • Yogurt — I love adding some plant-based yogurt (plain, unsweetened) for an even more tangy flavor.
  • Protein Powder — I add some vanilla protein powder for increased flavor and nutrients. If your protein powder is not sweetened, you may want to add an extra teaspoon or two of sweetener.
  • Cornstarch — We’ll use cornstarch to thicken the lemon curd topping.
  • Turmeric — A pinch of turmeric makes that lemon curd sunny yellow.
  • Vegetable oil — I use extra virgin olive oil. You can learn more about it and answer any questions, like is extra virgin olive oil vegan! If you need a substitute, you can use your favorite neutral vegetable oil, like avocado oil.
  • Onions — You’ll need 2 to 3 medium onions, peeled and diced.
  • Garlic — We’ll be using 2 to 3 cloves of garlic. You can substitute a teaspoon of garlic powder.
  • Sour cream — You can use storebought vegan sour cream or use this cashew cream.
  • Mayo — Let’s make it extra creamy with a bit of vegan mayo.
  • Seasonings — I season mine with vegan worcestershire sauce, salt, freshly ground black pepper, and dehydrated onions. You can substitute soy sauce if you don’t have any vegan Worcestershire on hand.
  • Herbs — Use fresh chives and thyme if you have them handy, otherwise, see the recipe card for substituting dried herbs.
