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.

Ingredients

Recipe makes 3 servings.

  • Rolled Oats (2 cups).
  • Non-fat Greek yogurt (1 cup), plain or vanilla. Not only does yogurt add some creaminess and additional protein, it is also a good source of calcium and live, active cultures to increase the beneficial bacteria in our gut.
  • Vanilla Protein Powder (2 scoops), optional. Make sure that you like the taste of the protein powder because some can have a weird aftertaste. Another option would be to omit the protein powder and use a higher protein milk instead of almond milk for additional protein.
  • Chia Seeds (3-4 tablespoons).
  • Jell-O Pistachio Instant Pudding Mix (3 Tbsp.)
  • Vanilla Almond Milk (2 cups), or preferred milk.
  • Honey (1 teaspoon). Adjust based on your sweetness preference. If using an unflavored protein powder or unflavored yogurt, more honey may be needed. Omit the honey if you prefer this to be less sweet – you could also always add it in later after it has refrigerated.
  • Toppings: chopped pistachios, sliced bananas or mixed berries, whipped cream, dark chocolate chips

Overnight oats are one of the easiest breakfast meal prep options and can make those busy mornings a lot less stressful. When creating recipes, I aim to find a balance between taste and nutrition. This recipe feels decadent yet it’s high in protein, fiber, and probiotics to increase the diversity of that good bacteria in your gut!

Variations Ideas

  • To Omit the Protein Powder: sub the almond milk with skim or Fairlife milk and add more pistachios for topping.
  • To Change the Consistency: add a little more milk for a thinner consistency and less if you prefer it thicker. The chia seeds also act as a thickener as well – so you could omit them or just add 1-2 tablespoons.
  • Make It Sweeter: add more honey and/or use a really sweet tasting protein powder.
  • Less Sweet: omit the honey – taste test after refrigeration.
  • For Even More Creaminess: Use coconut milk as your preferred milk.
  • If it tastes too gritty: try less of the pistachio pudding mix. A different protein powder may help as well.

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.
