Ingredients Needed

These pistachio overnight oats come together with just a few simple ingredients.

Measured ingredients needed to make pistachio overnight oats on a table including oats, chia seeds, non-dairy milk, maple syrup, matcha powder, vanilla extract, and pistachio butter.
  • Quick Oats: I’ve tested all different kinds of oats when creating my overnight oat recipes and discovered that quick oats give it the creamiest texture.
  • Non-Dairy Milk: Any non-dairy milk works here: soy, almond, or oat. I’ve also tried these with pistachio milk and it was amazing.
  • Pistachio Butter: I typically use homemade pistachio butter, but I’ve also made it with store-bought pistachio butter and it came out great!
  • Chia Seeds: Adds fiber, omega-3s, and helps thicken the mixture. I use them in my Chocolate Hazelnut Overnight Oats too.
  • Maple Syrup: Naturally sweetens the oats without any refined sugars.
  • Vanilla Extract: Just a drop enhances all the flavors.
  • Matcha Powder: This is optional, but if you want a vibrant green color without any artificial dyes, add 1/4 teaspoon of matcha powder. It doesn’t affect the flavor, but adds a beautiful green color!

Substitutions & Flavor Variations

  • Maple Syrup: Swap for agave.
  • Yogurt: I think these are creamy enough on their own, but feel free to add 1/4 cup of your favorite yogurt to make it even more creamy. Just make sure to use a vegan yogurt to keep this recipe vegan.
  • High Protein: Add one scoop of vanilla protein powder for a protein boost. Add extra milk as needed.
  • Chocolate-Pistachio Twist: Add one tablespoon of cocoa powder or dark chocolate chips for a Dubai chocolate inspired twist! My younger sister loves this variation.

Megan’s Tips

  • Mix thoroughly: Stir everything well, making sure there are no clumps of pistachio butter or matcha powder. We want that smooth and ultra creamy texture!
  • Add more milk if needed: If your oats are too thick in the morning, just add a splash of milk and stir. It’s completely normal for them to thicken as they sit.
  • Sweeten to taste: If you prefer a sweeter flavor, add a little more maple syrup or drizzle some on top before serving.
  • Wait to add your toppings: For the best texture, add your toppings just before serving. I especially love these with my Healthy Chocolate Granola.

Pistachio Overnight Oats FAQs

Are pistachio overnight oats healthy?

Yes! These pistachio overnight oats are made with wholesome ingredients like oats, chia seeds, and pistachio butter, which provide fiber and healthy fats.

Can I make pistachio overnight oats without chia seeds?

Yes. Chia seeds help thicken the oats, but you can leave them out. Just note that the texture will be slightly thinner, so you may want to reduce the milk slightly or add a bit more oats to compensate.

How long will pistachio overnight oats last in the fridge?

These pistachio overnight oats will last 3-5 days in the fridge. Perfect for meal prep!

Can I eat pistachio overnight oats warm?

Yes, you can absolutely enjoy these pistachio overnight oats warm if you prefer. After soaking, heat them in the microwave for 30–60 seconds. If the oats thicken too much after heating, just stir in a splash of non-dairy milk to bring back that creamy texture.
