Ingredients

• Rolled oats- A source of whole grains. You can also use quick oats, but I wouldn’t recommend steel cut oats because they need extra liquid.
• Greek yogurt- A high protein ingredient
• Milk
• Chia seeds- For healthy fats
• Lemon zest
• Blueberries- Fresh blueberries are fine, but you can also use frozen!
• Honey

Additions/Substitutions

Have special dietary needs or want to change things up? Here are some ideas!

• Milk: Use plant-based milk like almond milk, oat milk, coconut milk, or soy milk
• Greek yogurt: Use vanilla Greek yogurt or even a plant-based yogurt
• Ground flax seed
• Maple syrup instead of honey
• Vanilla protein powder for an extra boost of protein

What’s the best jar size for overnight oats?

I’ve done some research and have narrowed this down to two options. But the main answer is: It depends!

I really like the 8-ounce Mason jars because all the ingredients, as used above, fit perfectly in them. It fills right up to the top and simply looks pretty.

The 16-ounce Mason jars are also good because they give you more room to stir the ingredients. The only downside is that it looks like you’re not getting a lot of food because it only fills halfway.

Use the 8-ounce ones for portability, and the 16-ounce ones for ease of use and to add more stuff!

How long does it take to solidify?

Overnight oats become thick as it sits in the milk and yogurt, and becomes a pudding-like texture.

I’d say the minimum time to wait is 3-4 hours. But honestly, I think waiting overnight is best because, well, it’s in the name!

You can meal prep a bunch of these ahead of time so you can eat them all week.

How to make

In two Mason jars, divide and combine the oats, Greek yogurt, milk, chia seeds, lemon zest, blueberries, and honey. Place the lids on top and keep in the fridge overnight.

The next morning, give the ingredients a good stir and enjoy!

How long do overnight oats last in the fridge?

As long as they’re properly sealed, these will last between 5-7 days in the fridge. So feel free to make up a huge batch to eat from all week!
