What You Need

You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.

  • 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.
  • Vegan Mayo — I use a storebought mayo like Hellman’s Vegan Mayo, or sometimes I’ll mix in a little plain, unsweetened vegan yogurt to make a lighter version.
  • Relish — A little bit of sweet relish is the secret to this amazing sauce. If you don’t have relish, finely chop a few sweet pickles.
  • Green Onion — I like the mild flavor of green onion. We’ll use only the white part, chopped finely.
  • French Dressing — I used Kraft French Dressing, which gives this sauce color and flavor.
  • Vinegar — You’ll need just a bit of white vinegar for this recipe.
  • Sugar
