Eggnog Overnight Oats are a festive treat that combines creamy oats with the rich flavor of eggnog. Just mix oats, milk, and spices, then let them sit overnight!
In the morning, you’ll have a delicious breakfast that tastes like the holidays in a bowl. I love adding a sprinkle of nutmeg on top for a little extra cheer! 🎉
Key Ingredients & Substitutions
Rolled Oats: These are the foundation of the dish. They soak up the liquid well and create a creamy texture. If you prefer a chewier texture, you could use steel-cut oats, but they may require more soaking time.
Eggnog: You can use store-bought or homemade eggnog. If you’re looking for a lighter option, try using a reduced-fat version or even almond eggnog, which is dairy-free. In a pinch, substitute with milk flavored with vanilla and a bit of nutmeg.
Milk: Any type works here! I usually opt for almond or oat milk to keep it dairy-free. Coconut milk can also add a nice creaminess if you enjoy that flavor.
Sweeteners: Maple syrup is my go-to for a hint of natural sweetness, but you can use honey, agave nectar, or leave it out completely if you want it less sweet.
How Can I Achieve the Perfect Consistency?
Getting the right texture for your overnight oats is essential. If your oats are too thick in the morning, simply add a splash of milk to loosen them up. If they feel too runny, you might need a bit more oats or chia seeds to thicken them. Chia seeds absorb liquid, so if you’re using them, keep an eye on the mixture as they will continue to soak up moisture overnight.
- Mix everything well before refrigerating to help with even soaking.
- If using steel-cut oats, you may want to soak them a little longer (up to 12 hours).
- Stir the oats once more in the morning for an even creamier texture.

Eggnog Overnight Oats
Ingredients You’ll Need:
- 1/2 cup rolled oats
- 1/2 cup eggnog (store-bought or homemade)
- 1/4 cup milk (dairy or plant-based)
- 1/4 teaspoon ground cinnamon
- 1/8 teaspoon ground nutmeg, plus more for garnish
- 1 teaspoon maple syrup or honey (optional)
- 1/4 teaspoon vanilla extract
- Pinch of salt
- 1 tablespoon chia seeds (optional, for thicker texture)
- Rolled oats for topping (optional)
How Much Time Will You Need?
This recipe takes about 10 minutes of prep time. You’ll need to let the oats soak in the liquid overnight (or at least 6 hours) in the fridge. In total, you’re looking at just a short prep time, plus the time to chill!
Step-by-Step Instructions:
1. Mix The Ingredients:
In a jar or airtight container, combine the rolled oats, eggnog, milk, ground cinnamon, ground nutmeg, maple syrup or honey if you want it sweeter, vanilla extract, salt, and chia seeds if you’re looking for a thicker texture. Make sure everything is in there and ready to go!
2. Stir It Up:
Use a spoon or a small whisk to stir the mixture well. You want all the ingredients to blend together evenly so that the oats soak up the flavors nicely overnight.
3. Chill Overnight:
Seal the container with a lid and place it in the fridge. Let it sit overnight, or for at least 6 hours, so the oats can absorb the liquid and get nice and creamy. This waiting time is where the magic happens!
4. The Morning After:
When you wake up, take out your oats and give them another stir. If they seem too thick for your liking, don’t hesitate to add a splash of milk to loosen them up a bit.
5. Serve and Enjoy:
Spoon the oats into a serving jar or bowl if it’s not already there. You can top them with a dollop of whipped cream or a splash of extra eggnog, a sprinkle of ground nutmeg for that holiday vibe, and a few rolled oats on top for some extra texture. Isn’t it beautiful?
6. Delight in Your Creation:
Now, enjoy your festive Eggnog Overnight Oats chilled! It’s the perfect cozy breakfast for those holiday mornings. Cheers to a delicious start to your day!
Can I Use Instant Oats Instead of Rolled Oats?
Yes, you can use instant oats, but keep in mind they’ll make the mixture softer and mushier. If using instant oats, reduce the soaking time to about 2-3 hours to prevent them from getting too soggy.
What Type of Milk Can I Use?
You can use any type of milk you prefer! Almond milk, oat milk, coconut milk, or regular dairy milk all work well. Just choose an option that suits your taste and dietary preferences.
Can I Make These Oats Vegan?
Absolutely! Just use a plant-based eggnog and non-dairy milk. Maple syrup is also a great vegan sweetener, so you can enjoy a fully vegan version of these delicious oats!
How Long Can I Store Leftovers?
Leftover Eggnog Overnight Oats can be stored in the fridge for up to 3 days. Just make sure to keep them in an airtight container. Give them a good stir and add a splash of milk before eating to refresh their consistency!
