Recipe Ingredients & Mental Health Benefits
- Rolled oats (old-fashioned oats)

- Chopped pistachios
- Vanilla Greek yogurt (0% fat)
- Maple syrup
- Flaxseed or chia seeds (or a combination of both)
- Almond extract (or vanilla extract)
- Cinnamon

> Rolled Oats
The rolled oats are whole grains that are high in fiber, vitamins, and minerals. They are heart healthy, help stabilize blood sugar, and are good for your gut. Rolled oats and old-fashioned oats are the same thing.

> Milk
The milk in this recipe provides protein, calcium, vitamin D, and many other nutrients. I like to use nonfat dairy milk, but you can use any milk you like. If you are using plant-based milk, check the nutrition label for high amounts of protein and calcium.
> Pistachios
Pistachios provide protein, fiber, B vitamins especially vitamin B6, iron, and magnesium. These micronutrients are especially important for good mental health. Pistachios are among the top 5 nuts for brain and mental health.

> Nonfat Greek Yogurt
The nonfat Greek yogurt provides protein, calcium, and probiotics without any saturated fat. Probiotics are beneficial bacteria that improve your gut health, which then helps your mental health through the gut-brain axis.
> Flaxseed and/or chia seeds
The flaxseed and chia seeds are full of omega-3 fatty acids, which are vital for your mental health. I use ground flaxseed meal for the flaxseed because it’s easier for your body to use. Both these seeds are also anti-inflammatory foods.

- Use the milk you prefer, such as low-fat dairy milk, almond milk, or oat milk.

Pistachio Overnight Oats FAQ
Yes, you can use instant oats in overnight oats, but the texture will differ. Rolled oats are thicker and maintain their shape better after soaking, so they have a chewier texture you may prefer. Instant oats are thinner and break down more during soaking, so they have a softer, mushier texture.
Yes, you can use honey as a substitute for maple syrup in overnight oats. Honey will provide a slightly different flavor than maple syrup. You can also adjust the amount of honey you use based on your taste preference.
Yes, you can prepare overnight oats more than one night in advance. They will usually keep in the refrigerator for up to 5 days in a tightly sealed container. This makes them a great option for meal prepping at the start of the week.
Bottom Line
These pistachio overnight oats are a perfect blend of convenience, taste, and nutrition. They’re an excellent breakfast option that can help you maintain your health, boost your energy levels, and even improve your mood.
