These high protein and fiber pistachio pudding overnight oats are filling and absolutely delicious! They’re super creamy with a nutty, mild pistachio flavor. Easy to meal prep for a nutritious, grab-and-go breakfast! {Gluten-Free}

I am a big fan of using Jell-O Instant Pudding in various recipes. It adds flavor and a creamy thick consistency, especially to overnight oats. This is a fun pistachio pudding version of my popular Berry Cheesecake Overnight Oats recipe.
It’s a delicious combination of sweet and salty and a well-balanced, nutritional breakfast.

Why I Love These Overnight Oats:
- They’re delicious! The sweet pistachio pudding flavor with the vanilla yogurt and protein powder pairs well with the salty, crunchy pistachios on top. It’s thick and creamy – just the way I prefer my overnight oats.
- An already prepped breakfast in the fridge. Just 5 minutes of prep and you will have a healthy, delicious breakfast that’s portable and easy to grab-and-go.
- High protein and fiber. A breakfast that will help you reach a higher overall protein and fiber intake! Each serving has about 34 grams of protein and 12 grams of fiber! Both nutrients increase feelings of fullness and satisfaction so you’re less likely to overindulge at your next meal or turn to convenience snacks.
- May improve the composition of your gut microbiome. I love using Greek yogurt in overnight oats because it contains live, active cultures to promote a more diverse gut microbiome. Many brands, like Chobani, list the probiotic strains on the label. It’s one of the very few probiotic foods available. The fiber from the chia seeds are considered prebiotics- which help to feed that good bacteria in our gut.

Frequently Asked Questions
How can I make these dairy-free?
You can sub the Greek yogurt with a higher protein plant-based yogurt like Kite Hill. Another option is to use Lifeway vanilla flavored kefir in replace of Greek yogurt as it is 99% lactose-free and contains even more probiotics than yogurt. However, it does have less protein (add protein powder). You will need to decrease the amount of milk to about 1 1/2 cups.
Can I Use Instant or Steel-Cut Oats?
You can try it, but the texture will be different. Instant oats will provide a chewier texture and steel cut oats result in a tough consistency as well.
