Eggnog Overnight oats protips

  • Use rolled oats. You may also see these going by the name “old-fashioned oats,” and they will give you the best overnight oats texture!
  • Don’t skip the chia seed or flax meal! Chia or flax seeds help make the overnight oats nice, thick, and creamy.
  • Sweeten to taste. Eggnog is already pretty sweet, so you may not need to add any honey or maple syrup. Give the oats a taste before you add any sweetener.

Ingredients

Notes

  • Any eggnog will do the trick here—our dairy-free eggnog recipe and regular eggnog recipe both work great.
  • Eggnog is naturally pretty sweet, so you might not need to add any additional honey or maple syrup to your oats. I recommend tasting before adding additional sweetener.

Frequently Asked Questions about eggnog overnight oats

We prefer them cold, straight out of the fridge—that’s where they are at their creamiest and most pudding-like! But if you’d prefer a warm breakfast, you can heat these oats in the microwave for 30-60 seconds, stirring often, or in a small saucepan on the stove.

These overnight oats will be fine in the fridge for up to a week.

Sure can! Just make sure to use certified gluten-free oats, and you’ll be all set.

Choose a plant-based yogurt instead of Greek yogurt, and use our coconut milk eggnog, which is dairy-free.
