Key ingredients

Rolled oats – For the optimal chewy texture, use old fashioned rolled oats. Quick oats or instant oats work, but I do not recommend steel cut oats.

You may also substitute gluten free oats or rolled quinoa flakes.

Pistachios – These are the best pistachio overnight oats because they are packed with not one but two forms of pistachio. Stir pistachio butter into the base, and top it with chopped raw or roasted pistachios.

To save money, I make my own pistachio butter at home. It’s super easy: just process shelled pistachios in a food processor until silky smooth. You may substitute an equal amount of pistachio cream if you prefer.

Protein powder – This ingredient is optional, for those who want a high protein breakfast option to keep them full until lunch time.

Go with unsweetened protein powder, or choose a flavor that compliments pistachio, like vanilla, chai, or chocolate.

Yogurt – The recipe calls for half a cup of yogurt. I always use dairy free Greek yogurt to make vegan pistachio overnight oats. Once again, it works with flavored, sweetened, or plain unsweetened yogurt.

Milk – Any milk will do, including nondairy options like almond milk, coconut milk, or even pistachio milk. The milk adds a smooth creaminess to the oats.

Sweetener – Pure maple syrup, honey, or sugar free stevia are lovely options here.

The amount of sweetener will depend greatly on if you are using sweetened yogurt, milk, and protein powder. Some people might not want any additional sweetener at all.

Other ingredients – Superfood chia seeds add iron, calcium, and vitamins. Salt gives you depth of flavor. And I love to stir in a pinch of optional ground cardamom, because the floral cardamom and nutty pistachio combination is such a perfect culinary pairing.

How to make the best pistachio overnight oats

The recipe yields a single serving. It can easily be modified to feed a whole family or a crowd of hungry guests.

Begin by adding the rolled oats, chia seeds, salt, and optional protein powder and ground cardamom to a medium bowl or a mason jar. Stir well with a spoon.
Whisk in the milk of choice, yogurt, pistachio butter, and sweetener until smooth. If you prefer blended oats, feel free to use a small blender instead of a whisk or fork to combine everything together.
Stir in chopped pistachios now, or reserve the nuts for garnish at the end.
You can either enjoy these creamy pistachio oats right away or cover tightly and refrigerate overnight, during which time their texture will thicken considerably.
Sprinkle on toppings as desired. Then eat cold from the jar. Or warm up in the microwave or in a small saucepan on the stove top until hot.
Refrigerate any leftovers in an airtight covered container for up to five days, or freeze and reheat before serving.

Pistachio oatmeal topping ideas

I like to garnish the oats with chopped pistachios, mini dark chocolate chips, and sometimes fresh raspberries, pomegranate seeds, or sliced bananas.

You can also add a spoonful of coconut butter or Homemade Nutella.

Want to be really fancy? Stir one teaspoon of cocoa powder with one teaspoon each of melted coconut oil and pure maple syrup or agave. Spread this raw chocolate ganache over the top to create your own Dubai chocolate overnight oats.

Add elegance with a dusting of cocoa or matcha powder, or a burst of citrus flavor with a half teaspoon of orange zest and a sprinkle of white chocolate chips.

Average, boring oatmeal? Not a chance.

Health benefits of pistachio overnight oats

This hearty, filling breakfast can be gluten free, soy free, cholesterol free, low saturated fat, refined sugar free, egg free, and vegan.

Plus it gives you close to 50 grams of protein for under 400 calories total.

Superfood pistachios offer an array of vitamins and minerals, including copper, manganese, fiber, and potassium.

And you get whole grains from the rolled oats, along with calcium, iron, and omega-3 fatty acids thanks to the milk, yogurt, and chia seeds.

Creamy Pistachio Overnight Oatmeal Recipe (Vegan, Added Sugar Free)

Recipe adapted from my Blueberry Overnight Oats and Protein Overnight Oats.

*This recipe makes one jar. Feel free to scale up all ingredients if you want multiple servings to feed a family or meal prep for the week.
1. Combine oats, chia seeds, salt, and optional protein powder and cardamom in a medium bowl or mason jar. Stir well.
2. Whisk in milk, yogurt, softened pistachio butter, and sweetener of choice until smooth and evenly incorporated.
3. You can stir in half the chopped pistachios now, or reserve them all for garnishing the top.
4. Cover and refrigerate the oatmeal overnight. The oats thicken as they chill, yielding a delicious thick texture the next morning. (You can eat the oats right away if you prefer a thinner texture.)
5. Enjoy cold, or warm up in the microwave or a small saucepan on the stove.
6. Refrigerate leftovers in a covered container for up to five days.
