Nessy's Note
When I have busy mornings coming up in the week, overnight oats is one of my go to breakfasts to prep.
Because when you have a base as good as my Greek yogurt overnight oats (which has just 3 base ingredients, is high protein without the need for protein powder and is thick and creamy- just how I like it!), it is easy to whip up all sorts of filling flavors (like cookie dough ONOs).
And when I want to feel like I'm eating something like a blueberry cheesecake to start the day, this version is the one I make.
Ingredients and Substitutions

- Rolled Oats- These also can be called old-fashioned oats or large flake oats. They're my go-to for all of my overnight oats recipes (like almond butter overnight oats).
- Substitution: Instant or quick oats work but result in a bit of a "mushy" texture. Steel-cut oats won't work.
- Greek Yogurt- This makes the oats higher protein without the need for protein powder and provides most of the liquid to soak the oats for the recipe.
- Substitution: Another type of plain yogurt can be used but note that the protein content will vary.
- Honey- For some extra sweetness.
- Substitution: Maple syrup or your sweetener of choice can be used instead or if you find it sweet enough with just the berries, it can be left out.
- Chia Seeds- These add extra fiber and thicken the overnight oats.
- Substitution: Ground flaxseed can be used instead or they can be left out.
- Sea Salt- A pinch really brings the flavors together.
- Substitution: Kosher or table salt will also work or it can be left out.
- Blueberries- I usually use frozen blueberries because I always have some on hand, they tend to be less expensive and it makes the recipe quicker to make because you don't even have to thaw them. Fresh will work too, though.

My Notes for the Best Blueberry Overnight Oats
- Use frozen berries. While you can use fresh, frozen berries make it super easy to prep and tend to be a less expensive. Plus as they thaw overnight, they let out juices which seep into the oats and add more flavor.
- Adjust the consistency. If the oats have thickened too much overnight for your liking (they are pretty thick), you can stir in a splash of milk (or water) before serving.
- Meal prep for the week. These last up to 4-5 days in the fridge, so you can make a batch on Sunday and have breakfast ready for most of the week.

These oats are ready to eat straight from the fridge but if you prefer them warm, microwave in 20-second intervals, stirring between each, until heated to your desired temperature. Be careful not to overheat as the yogurt can curdle.
